Vincent A. De Gaetano, President, Branko Lubarda , Helen Keller, Pere Pastor Vilanova , Alena Poláčková , Georgios A. Serghides , María Elósegui , judges, and Stephen Phillips , Section Registrar ,

Having deliberated in private on 23 October 2018 ,

Delivers the following judgment, which was adopted on that date:

PROCEDURE

1 . The case originated in applications (nos. 65101/16 , 73789/16 and 73902/16 ) against the Kingdom of Spain lodged with the Court under Article 34 of the Convention for the Protection of Human Rights and Fundamental Freedoms (“the Convention”) by Spanish nationals, Mr Santiago Arrozpide Sarasola (“the first applicant ”), Mr Alberto Plazaola Anduaga ( “the second applicant ” ) and Mr Francisco Múgica Garmendia ( “the third applicant” ) on 4 November 2016 , 23 November 2016 and 21 November 2016 respectively .

2 . The first applicant w as represented by Mr I. Urbina Fernandez, a lawyer practising in Vitoria- Gasteiz . The second and third applicants were represented by Ms H. Ziluaga Larreategi , a lawyer practising in Hernani. The Spanish Government (“the Government”) were represented by their Agent, Mr R.-A. León Cavero , State Counsel and Head of the Human Rights Department at the Ministry of Justice .

3 . The applicants alleged, in particular, a violation of Articles 6, 7 and 5 § 1 of the Convention .

4 . On 18 January 2017 the Government were given notice of the complaint under A rticle 6 § 1 concerning right of access to the Constitutional Court and the complaints concerning A rticles 7 and 5 § 1 of the Convention. The remainder of the applications was declared inadmissible by the then V ice- President of the S ection, sitting in single-judge formation .

THE FACTS

5 . The applicants were born in 1948 , 1956 and 1953 respectively . The first applicant was detained in Topas Prison when his application was lodged with the Court . Th e third applic ant is detained in Zuera Prison . The second applic ant was living in Ciboure (France) when his application was lodged with the Court .

6 . On 30 September 1987 the first applic ant was arrested in France.

7 . On 3 October 1987 he was placed in detention in France for belonging to the ETA terrorist organisation .

8 . On 4 July 1990 the Paris Regional Court sentenced him to ten years ’ imprisonment on charges of criminal conspiracy , breach of the law on arms and explosives , breach of the Electronic Mail and Communications C ode and an offence related to individual or collective action aimed at creating public disorder through intimidation or terro r. That con vic tion concerned offences committed in France in 1987. The first applicant served his sentence up until 3 October 1995, after a full prison term of seven years.

9 . Th e first applic ant then remained in detention in France, for the purposes of extradition, until 21 December 2000, when he was surrendered to the Spanish judicial authorities pursuant to an extradition request .

10 . In Spain , the first applic ant was sentenced to more than three thousand years ’ imprisonment after eleven separate sets of criminal proceedings before the Audiencia Nacional . He was con victed of several terrorist attacks and murders committed in Spain between 1980 and 1987 by the ETA terrorist organisation , i n cluding the booby-trapped car explosion on the Plaza R e p ú bli ca Dominicana in Madrid on 14 July 1986 ( killing twelve Guardia C ivil officers and injuring forty-four Guardia C ivil officers and seventeen pass ers-by ) and the car-bomb attack on the Hipercor shopping centre in Barcelona on 19 June 1987 ( killing twenty-one people and injuring forty-six others ).

11 . Once the con vic tions in Spain had become final by decision of 7 March 2006, the Audiencia Nacional noted that the chronological l inks between the offences of which she had been convicted made it possible to group them together ( acumulación de penas ) as provided for in section 988 of the Criminal Procedure Act ( Ley de Enjuiciamiento Criminal ) in conjunction with Article 70.2 of the 1973 Criminal Code, in force when the offences were committed (see “ relevant domestic law and practice” in the case of Del Río Prada v. Spain [GC], no. 42750/09 , §§ 24-25, E CHR 2013) . The Audiencia Nacional fixed the maximum term to be served by the first applicant in respect of all h is prison sentences in Spain combined at thirty years .

12 . On 27 June 2006 an initial calcul ation was carried out for the purposes of fixing the date on which he would have finished serving h is sentence ( liquidación de condena ) , s tating that the first applic ant would be released on 30 January 2030.

13 . At the first applic ant ’ s request , the period of detention in France for the purposes of extradition ( from 3 October 1995 to 21 December 2000) was deducted from the maxim um prison term by decision of 24 May 2011 of the Audiencia Nacional . Consequently , the prison authorities re calcul ated the prison term and fixed the date on which he would have finished serving his sentence for 24 September 2025. That calcul ation was confirmed by an ord er issued on 27 September 2011 by the Audiencia Nacional .

14 . Following the judgment delivered by the Court in the case of Del Río Prada , cited above , the first applic ant sought and ultimately obtained a re calcul ation of his prison term, fixing the date of his release on 21 July 2020 , which was approved by decision of 28 February 2014. The remissions of sentence to which the applicant was entitled were deducted from the maximum term of thirty years ’ imprisonment , rather than from each of the sentences separately ( see , as regards the consequences of the Del Río Prada judgment f or other con victed persons , Lorenzo Vázquez v . Spain ( d e c. ), n o. 30502/12, §§ 19-24, 19 January 2016), for the purposes of determining his release date.

15 . On 25 March 2014 the first applic ant requested the deduction of the prison sentence imposed by the French judicial authorities and served in France from the maximum thirty-year term established in Spain . He relied on judgment n o. 186/2014 of 13 March 2014 of the Supreme Court, which had accepted the possibility of taking into consideration a sentence served in France for the purposes of group ing together sentences on the basis of Framework Decision n o. 2008/675/JAI of the Council of the European Union of 24 July 2008 on taking account of convictions in the Member States of the European Union in the course of new criminal proceedings ( “ Framework Decision n o. 2008/675/JAI ” ) ( see “ relevant domestic and EU law and practice ”, paragraphs 73-77 and 83 below ).

16 . By decision of 2 December 2014 the Audiencia Nacional ( first section of the Criminal Division ) a greed to deduct the prison term served in France from the maximum term of thirty years ’ imprisonment . The Audiencia relied, in particular, on judgment n o. 186/2014 delivered by the Supreme Court on 13 March 2014, a s well as Framework Decision n o. 2008/675/JAI, particularly A rticle 3 § 1 thereof , which provides that each Member State of the European Union ( “ the EU ” ) should ensure that in the course of criminal proceedings against a person, previous convictions handed down against the same person for different facts are taken into account to the extent previous national convictions are taken into account . The Audiencia Nacional took the view that a previous con vic tion handed down in another Member State should th erefore be taken into account in calcul ating the maxim um prison terms provided in criminal la w .

17 . Th e public prosecutor ’ s office lodged an appeal on points of law with the Supreme Court against that decision , for the purposes of clarifying the law . In the framework of those proceedings , the first applic ant requested an application for a preliminary ruling from the Court of J ustice of the European Union ( “ the CJ E U ” ) on the basis of A rticle 267 of the Treaty on the Functioning of the European Union . Moreover , he pointed out that allowing the appeal on points of law would violate the principle that only a statute can define offences and lay down penalties, the right to liberty , the right to equality before the la w and the right to effective judicial protection.

18 . On 4 December 2014, while the appeal on points of law was pending before the Supreme Court , the Audiencia Nacional re calcul ated the sentence to be served by the first applic ant under the impugned decision. It noted that pursuant to that decision , and taking account of the sentence served in France for the purposes of group ing the sentences together , the applicant ought to have finished serving his sentence on 27 January 2013.

19 . On 21 December 2014 the first applic ant was released from prison. He was placed in pre-trial detention on 20 January 2015 in relation to offences committed in 1986 and 1987 f or which he had not yet stood trial .

20 . On 10 March 2015 the Supreme Court allowed the appeal on points of law lodged by the public prosecutor ’ s office for the purposes of clarifying the law . In its judgment , which was delivered and published on 24 March 2015, i t held that there had been no need to take account of the sentence served by the fi r st applic ant in France for the purposes of group ing sentences together ( acumulación de penas ) . The Supreme Court had followed the s ame approach as in its leading judgment n o. 874/2014 of 27 January 2015, by which the Plenary Criminal Division had decided not to take account of sentences imposed and served in France in tandem with sentences imposed in Spain for the purposes of determining the maxim um prison term ( see “ R elevant law and practice at the domestic and EU levels ” , paragraph 69 below ).

21 . Referring to the reasoning set out in its leading judgment n o. 874/2014 of 27 January 2015, the Supreme Court reiterated all the applicable case-law and legislation concerning the consideration of sentences imposed abroad . It identified three different periods in this regard: the first period up until 15 August 2008, the date of publication of Framework Decision no. 2008/675/JAI; the second extending between that date and the date of publication of Organic Law no. 7/2014 of 12 November 2014 on the exchange of information from police records and taking account of criminal court decisions in the EU, which had come into force on 3 December 2014; and lastly, the third period from the date of publication of the aforementioned organic law to the present day. As regards the first period , the Supreme Court noted that the Spanish courts had only agreed to take account of sentences imposed abroad alongside those imposed in Spain where the sentence imposed abroad was to be served in Spain under an international treaty on the execution of criminal judgments ( for example a bilateral treaty o r the Council of Europe ’ s Convention on the Transfer of C on victed persons ). On the other hand, it pointed out that when the sentence had already been served abroad, there was no reason t o consider it in connection with sentences to be served in Spain for the purposes of implementing the maxim um prison term ( judgment n o. 2117/2002 of 18 December 2002). Concerning the second period (mi d - August 2008 to November 2014), the Supreme Court observed that under the Framework Decision itself ( A rticle 3 § 5), i t was not compulsory for S tat e s to take account of a sentence imposed in another Member State for the purposes of applying the maxim um prison term set out in the Penal Code . The court added, however, that as it transpired from its judgment n o. 186/2014 of 13 March 2014, in the absence of domestic legislation transposi ng the Framework Decision or of rules express ly governing this matter , the rules in force should be interpreted in a manner as compatible as possible with the content of European regul ation s, provided that such interpretation was not contra legem where domestic law was concerned. It pointed out that it was in that context that judgment n o. 186/2014, which had been enacted before the transposition of the Framework Decision , had agreed to take into consideration a sentence imposed in France for the purposes of grouping it together with sentences subsequently imposed in Spain . F in ally , a s re g ards the third period , the Supreme Court noted that Organic Law n o. 7/2014 had incorporated the Framework Decision into Spanish law, while expressly ruling out the effects of sentences imposed in another Member State in calculating the length of sentences given in Spain f or offences committed before any sentences handed down by the courts of the other Member State ( section 14 ( 2 ) of Organic L a w no. 7/2014 ). It considered that under those circumstances , even though the aim was not to apply that law direct ly, its existence meant that it was no longer possible to interpret Spanish law ( A rticle 70.2 of the Penal Code and section 988 of the Criminal Procedure Act ) in the previously accepted sens e, that is to say in favour of taking into account sentences imposed in another Member State for the purposes of calculating the maxim um prison term . Given that the Spanish State, through the intermediary of its legislature, had expressed its choice in the transposi tion of the Framework Decision , ruling out any consideration of sentences imposed in another Member State, the previous interpretation was no longer possible, because it was no longer praeter legem bu t contra legem .

22 . Furthermore , in its judgment , the Supreme Court had considered whether Organic Law n o. 7/2014 was compatible with the Framework Decision , and concluded that the exceptions provided for in the C onsideration of S entences imposed in other Member State s Act were authorised by the optional exception set out in A rticle 3 § 5 of the Framework Decision .

23 . The Supreme Court also considered that the new interpretation of the law set out in its judgment n o. 874/2014 did not contravene A rticle 7 of the Convention read in the light of the Court ’ s case-law . It took the view that the change of interpretation could not be compar ed with the reversal of case-law which had given rise to the case of Del Río Prada. Firstly , the Supreme Court held that it would be difficult for an interpretation based on such a legal instrument as a Framework Decision , which itself introduced optional exceptions for its transposition , to give rise to legitimate expectations . Secondly , it considered that it was a case of a pre- established case-law or interpretative practice laying down the general rule of consideration of sentences already served abroad . T hi r dly , i t pointed out that judgment n o. 186/2014 of 13 March 2014 had been the first decision in which it had been called upon to interpret the Framework Decision , at a time when the commonly accepted practice of the courts in similar cases had been to refuse to take account of sentences served abroad . Fourthly, the court emphasised that in the absence of any established case-law , the first applic ant could not, when he had been serving his prison sentence , have legitimately expected that the sentence already served in France would be taken into consideration for the purposes of applying the maxim um prison term in Spain . I t concluded that even though the impugned interpretation differed from that adopted in judgment n o. 186/2014, that change was not such as to infringe any expectation on the first applic ant ’ s part based on reasonable foreseeability . Moreover , i t considered that that foreseeability could never have existe d either at the time the first applicant had committed the offences in France (1987) or at the time the decision was taken to group together sentences in Spain (2006), since the Framework Decision had not yet been adopted then and no judicial precedent had supported the taking into account of sentences served abroad . Finally , the Supreme Court held that the first applic ant must have known that the Framework Decision had to be implemented at the domestic level , and pointed out that such transposition would determine wheth er or no t sentences imposed in another Member State could be taken into account under the optional exception set forth in A rticle 3 § 5 of the Framework Decision itself . It noted that ultimately, Spanish law as a whole, including the relevant case-law, had not been drawn up sufficiently precisely for the argument advanced by the applicant to be accepted as established and evident.

24 . As regards the first applic ant ’ s desire to request a preliminary ruling from the CJ E U , the Supreme Court held that that was unnecessary in view of the cl e ar wording of A rticle 3 § 5 of the Framework Decision read in its context and in the light of the proce dure for adopting that instrument.

25 . The Supreme Court had adopted its judgment by four votes to one. One judge had appended a dissenting opinion submitting that the exceptions laid down in Organic Law n o. 7/2014 on taking account of sentences imposed in another Member State were contrary to the sp i rit of the Framework Decision and destroyed the very essence of the equivalence objective which that instrument was supposed to enshrine .

26 . On 13 March 2015 the Audiencia Nacional took note of the communication of the Supreme Court judgment and of the latter ’ s annul ment of the 2 December 2014 decision on group ing sentences together in respect of the first applic ant, thus rendering inoperative the latest calculation of the prison term to be served . It stated that the first applic ant now had to continue serving his prison sentence .

27 . On 10 April 2015 the 24 March 2015 judgment of the Supreme Court was served on the first applic ant ’ s representative . The notice accompanying the judgment stated that the latter was final and could be the subject of an amparo appeal before the Constitutional Court within thirty working days.

28 . On 15 April 2015 the first applic ant filed an action ( incidente de nulidad ) to set aside the judgment of the Supreme Court on the basis of section 241 ( 1 ) of the Organic Law on the J udiciary ( “ LOPJ ” ) ( see “ R elevant law and practice at the domestic and EU levels ” , paragraph 69 below ), alleging in particular an infringement of the principle that only a statute can define offences and lay down penalties, the right to liberty, the right to equality before the law and the right to effective judicial protection . He requested that his action be dealt with under urgent procedure so that he could lodge an amparo appeal before the Constitutional Court within the thirty-day time-limit.

29 . On 25 May 2015 the first applic ant requested the withdrawal of his action on the grounds that the Supreme Court , which had delivered the impugned cassation judgment , had already had an opportunity to reply to his allegations of breaches of fundamental rights .

30 . On 26 May 2015 the first applic ant lodged an amparo appeal with the Constitutional Court . He relied on Article 14 ( equality principle ), Article 17 ( right to liberty ), Article 24 ( right to effective judicial protection) and Article 25 ( principle that only a statute can define offences and lay down penalties ) of the Constitution. He once again requested that the CJ E U be invit ed to give a preliminary ruling . Regarding the requirement of exhaustion of available domestic remedies, the first applic ant p ointed out that no ordinary appeal lay with the cassation judgment and that the Supreme Court had already determined all the allegations of violations of fundamental rights, redress for which he was now seeking before the Constitutional Court .

31 . At a subsequent date (27 May 2015 according to the applicant and 8 June 2015 according to the Government ) the first applic ant was served with a decision of the Supreme Court date d 30 April 2015 declaring his action for annul ment in admissi ble. In that decision the Supreme Court stated that most of the applicant ’ s complaints had already been assessed in its cassation judgment , and that consequently, pursuant to section 241 ( 1 ) LOPJ , the action should be declared i nadmissi ble.

32 . On 24 May 2016 the Constitutional Court declared the amparo appeal i nadmissi ble on grounds of non- exhaustion of existing legal remedies, relying on section 44 ( 1 ) ( a) of the Organic Law on the Constitutional Court . That court noted that the first applic ant had not lodged an action for annul ment base d on section 241 ( 1 ) LOPJ.

B. Application n o. 73789/16

33 . Th e second applic ant was arrested in France on 18 November 1990. He was subsequently placed in pre-trial detention .

34 . By judgment of 11 March 1994 the Paris Regional Court sentenced him to seven years ’ imprisonment on charges of criminal conspiracy ( terrorism ), transport of arms and munitions and use of forged documents, in respect of offences committed in French territory in 1990. In its decision the court noted that the applicant was a member of the ETA.

35 . Th e second applic ant served that sentence in France up until the date of his extradition to Spain on 11 March 1996.

36 . By judgment of 31 July 1997 the Audiencia Nacional sentenced the second applic ant to a forty- six years ’ imprisonment for two attempted murders and damage to property, in connection with a terrorist attack on a bar in Eskoriaza ( Guipuscoa Province ) on 22 May 1987. The judgment stated that regard would be had to the upper limit set out in A rticle 70.2 of the 1973 Penal Code , which provided for a maxim um prison term of thirty years. The judgment was upheld by the Supreme Court on 12 June 1998 f ollowing an appeal on points of law .

37 . On 18 August 1998 an initial calculation was carried out for the purposes of fixing the date on which he would have finished serving his sentence ( liquidación de condena ), stating that the first applicant would be released on 3 March 2026. The Audiencia Nacional approved that calcul ation on 27 August 1998.

38 . On 20 March 2014 the second applic ant requested that the prison sentence imposed by the French judicial authorities and served in France be taken into account in determining the maximum thirty -year prison term set in Spain . He relied on judgment n o. 186/2014 of the Supreme Court of 13 March 2014 and Framework Decision n o. 2008/675/JAI of 24 July 2008.

39 . By decision of 2 December 2014 the Audiencia Nacional ( first section of the Criminal Division ) agreed to deduct the prison term served in France from the maximum term of thirty years ’ imprisonment. The Audiencia relied, in particular, on judgment no. 186/2014 delivered by the Supreme Court on 13 March 2014, as well as Framework Decision no. 2008/675/JAI, particularly Article 3 § 1 thereof, which provides that each Member State of the European Union (“the EU”) should ensure that in the course of criminal proceedings against a person, previous convictions handed down against the same person for different facts are taken into account to the extent previous national convictions are taken into account .

40 . The public prosecutor ’ s office lodged an appeal on points of law with the Supreme Court against that decision, for the purposes of clarifying the law. In the framework of those proceedings, the second applicant requested an application for a preliminary ruling from the CJEU on the basis of Article 267 of the Treaty on the Functioning of the European Union. Moreover, he pointed out that should the appeal on points of law be allowed, that would violate the principle that only a statute can define offences and lay down penalties, the right to liberty, the right to equality before the law and the right to effective judicial protection .

41 . On 2 December 2014 the Audiencia Nacional re calcul ated the sentence to be served by the second applic ant in accordance with the impugned decision . It noted that pursuant to that decision and having taken into account the sentence served in France for the purposes of group ing sentences together , the applicant should have completed his sentence on 24 August 2013. The Audiencia Nacional also had regard to the ordinary remissions of sentence to which the second applic ant was entitled and which had to be deducted from the thirty-year limit .

42 . On 4 December 2014 the Audiencia Nacional confirmed that calcul ation and the second applic ant was released from prison .

43 . On 10 March 2015 the Supreme Court allowed the appeal on points of law lodged by the public prosecutor ’ s office for the purposes of clarifying the law . In its judgment , which was delivered and published on 24 March 2015, i t held that there had been no need to take account of the sentence served by the first applicant in France for the purposes of grouping the sentences together . The Supreme Court had followed the same approach as in its cassation judgment concerning the first applic ant (see paragraphs 20-24 above) , referring to the approach which it had adopted in its leading judgment no. 874/2014 of 27 January 2015 . One judge had appended a dissenting opinion to the judgment .

44 . Also on 10 March 2015, the cassation judgment was communicated to the Audiencia Nacional . The latest calcul ation of the prison term to be served by the second applic ant was rendered inoperative and the previous calcul ation was reinstated. The Audiencia Nacional therefore fixed the date on which the second applicant would have finished serving his sentence as 16 August 2018 ( liquidación de condena ), and ord ered his recall to prison.

45 . Just as he was to return to prison, the second applicant absconded and remained untraceable. International arrest warrants were issued, and once he had been loca ted, an extradition request was issued to the French State.

46 . On 10 April 2015 the 24 March 2015 judgment of the Supreme Court was served on the second applicant ’ s representative. The notice accompanying the judgment stated that the latter was final and could be the subject of an amparo appeal before the Constitutional Court , to be lodged within thirty working days .

47 . On 17 April 2015 the second applicant filed an action to set aside the judgment of the Supreme Court on the basis of section 241 (1) of the Organic Law on the judiciary (“LOPJ”), alleging in particular an infringement of the principle that only a statute can define offences and lay down penalties, the right to liberty, the right to equality before the law and the right to effective judicial protection. He requested that his action be dealt with under urgent procedure so that he could lodge an amparo appeal before the Constitutional Court within the thirty-day time-limit .

48 . On 26 May 2015 the second applicant requested the withdrawal of his action on the grounds that the Supreme Court, which had delivered the impugned cassation judgment , had already had an opportunity to reply to his allegations of breaches of fundamental rights .

49 . On the same da te the second applicant lodged an amparo appeal with the Constitutional Court. He relied on Article 14 (equality principle), Article 17 (right to liberty), Article 24 (right to effective judicial protection) and Article 25 (principle that only a statute can define offences and lay down penalties ) of the Constitution. He once again requested that the CJEU be invited to give a preliminary ruling. Regarding the requirement of exhaustion of available domestic remedies, the first applicant pointed out that no ordinary appeal lay with the cassation judgment and that the Supreme Court had already determined all the allegations of violations of fundamental rights, redress for which he was now seeking before the Constitutional Court .

50 . On 27 May 2015 the second applicant was served with a decision of the Supreme Court dated 30 April 2015 declaring his action for annulment inadmissible. In that decision the Supreme Court stated that most of the applicant ’ s complaints had already been assessed in its cassation judgment , and that consequently, pursuant to section 241 (1) LOPJ, the action had to be declared inadmissible .

51 . The second applic ant was arrested in France on 7 September 2015. I t transpires from the case file that the Government adopted an agreement to request his extradition on 9 October 2015.

52 . On 22 June 2016 the Constitutional Court declared the amparo appeal inadmissible on grounds of non-exhaustion of existing legal remedies, relying on section 44 (1) (a) of the Organic Law on the Constitutional Court. That court noted that the first applicant had not lodged an action for annulment based on section 241 (1) LOPJ .

C. Application no. 73902/16

53 . The third applicant was arrested in France on 29 March 1992 in the framework of an operation against the main ETA leaders .

54 . By judgment of 19 June 1997 , the Paris Regional Court sentenced him to ten years ’ imprisonment on charges, in ter alia , of criminal conspiracy, unlawful possession of arms and munitions and use of forged documents, in respect of offences which had been committed in French territory between 1990 and 1992. The third applic ant served that sentence i n France.

55 . On 8 February 2000 he was surrendered to the Spanish judicial authorities pursuant to an extradition request .

56 . In Spain the third applic ant was sentenced to over four thousand seven hundred years ’ imprisonment following seventeen separate sets of criminal proceedings before the Audiencia Nacional . He was convicted, inter alia , of several terrorist attacks and murders (twenty-three in all) committed in Spain (Madrid, Zaragoza, Santander and Valencia) between 1987 and 1993.

57 . On 4 December 2012, once the sentences imposed in Spain had become final, the third applic ant requested the grouping together of the sentences for the purposes of determining the maximum prison term to be served ( thirty years ). He did not refer to the sentence served in France.

58 . B y decision of 18 November 2013 , the Audiencia Nacional noted that the chronological links between the offences of which she had been convicted made it possible to group them together ( acumulación de penas ) as provided for in section 988 of the Criminal Procedure Act ( Ley de Enjuiciamiento Criminal ) in conjunction with Article 70.2 of the 1973 Criminal Code, in force when the offences were committed. The Audiencia Nacional fixed the maximum term to be served by the first applicant in respect of all his prison sentences in Spain combined at thirty years .

59 . By decision of 11 April 2014 , the Audiencia Nacional approved the calcul ation of the sentence to be served by the third applic ant, taking account of the remissions of sentence to which he was entitled. The date on which he would have finished serving his sentence ( liquidación de condena ) was fixed for 13 November 2024.

60 . On 30 April 2014 the third applic ant requested that the prison sentence which he had served in France be taken into account in determining the maximum thirty -year term . He relied in particular on judgment n o. 186/2014 of the Supreme Court and Framework Decision n o. 2008/675/JAI.

61 . By decision of 2 December 2014, the Audiencia Nacional ( first section of the Criminal Division ) agreed to deduct the prison term served in France from the maximum term of thirty years ’ imprisonment. The Audiencia relied, in particular, on judgment no. 186/2014 delivered by the Supreme Court on 13 March 2014, as well as Framework Decision no. 2008/675/JAI, particularly Article 3 § 1 thereof, which provides that each Member State of the European Union (“the EU”) should ensure that in the course of criminal proceedings against a person, previous convictions handed down against the same person for different facts are taken into account to the extent previous national convictions are taken into account .

62 . That decision was contested on points of law before the Supreme Court by the public prosecutor ’ s office for the purposes of clarifying the law, and by the third applic ant. The latter requested the consideration of the whole sentence imposed in France ( ten years ), encompassing the remissions of sentence given, and not exclusively the time actually spent in prison ( from 29 March 1992 to 7 February 2000 – seven years and eleven months ). In the framework of the cassation proceedings , the t hi r d applic ant requested that the CJ E U be invit ed to give a preliminary ruling on the basis of A rticle 267 of the Treaty on the Functioning of the European Union . Furthermore, he complained of an infringement of the principle that only a statute can define offences and lay down penalties, the right to liberty, the right to equality before the law and the right to effective judicial protection .

63 . On 3 December 2014, the date on which the third applicant would have finished serving his sentence ( liquidación de condena ) was fixed for 21 March 2022, pursuant to the impugned decision and after deduction of the prison sentence served in France from 29 March 1992 to 7 February 2000. Having regard to the remissions of sentence already granted, deductible from the maximum thirty-year term, his final date of release ( licenciamiento definitivo ) was fixed for 5 August 2016.

64 . On 23 April 2015 the Supreme Court allowed the appeal on points of law lodged by the public prosecutor ’ s office for the purposes of clarifying the law, holding that there had been no need to take account of the sentence served by the third applicant in France for the purposes of grouping sentences together. The Supreme Court had followed the same approach as in its judgments concerning the first and second applicants (see paragraphs 20-24 above), while also referring to the approach adopted in its leading judgment no. 874/2014 of 27 January 2015 . Two judges appended a dissenting opinion to the Supreme Court ’ s judgment. The appeal on points of law lodged by the third applic ant was dismissed .

65 . On 18 May 2015 the judgment of the Supreme Court was communicated to the Audiencia Nacional and served on the third applic ant, who was represented by the same solicitor as the first and second applic ants. The notice accompanying the judgment stated that the latter was final and could be the subject of an amparo appeal before the Constitutional Court within thirty working days .

66 . On 20 May 2015 the latest calcul ation of the prison term to be served by the third applicant was rendered inoperative . Th e previous calcul ation was re - validated and updated by taking account of the further applicable remissions of sentence . According to that calcul ation , approved by the Audiencia Nacional on 21 July 2015, th e t hi r d applic ant would have finished serving his sentence ( liquidación de condena ) on 14 March 2024.

67 . On 26 June 2015 the third applic ant lodged an amparo appeal with the Constitutional Court . He relied on Article 14 (equality principle), Article 17 (right to liberty), Article 24 (right to effective judicial protection) and Article 25 (principle that only a statute can define offences and lay down penalties ) of the Constitution. He once again requested that the CJEU be invited to give a preliminary ruling. Regarding the requirement of exhaustion of available domestic remedies, the th ir d applicant pointed out that no ordinary appeal lay with the cassation judgment and that the Supreme Court had already determined all the allegations of violations of fundamental rights, redress for which he was now seeking before the Constitutional Court .

68 . On 22 June 2016 the Constitutional Court declared the amparo appeal i nadmissi ble on grounds of non- exhaustion of existing domestic remedies , relying on section 44 ( 1 ) ( a) of the Organic Law on the Constitutional Court . That court noted that the first applicant had not lodged an action for annulment based on section 241 (1) LOPJ.

A. A ction for annul ment

69 . Section 241 ( 1 ) of the Organic Law on the Judiciary ( “ LOPJ ” ) as amended under the first final provision of Organic Law n o. 6/2007 of 24 May 2007 provides :

“ As a general rul e, actions for the annul ment of judicial decisions must be declared i nadmissible . In exceptional cases, however , legitimate or potentially legitimate parties may request in writing that judicial decisions be declared nul l and void on grounds of a violation of a fundamental right secured under A rticle 53 § 2 of the Constitution, p rovided that such violation could not have be en complained of before the delivery of the judgment or decision terminating the proceedings , and that , in either cas e , no ordinary or extraordinary remedy lies with the judgment or decision .”

B. Organic Law on the Constitutional Court

70 . Section 44 ( 1 ) ( a) of the Organic Law on the Constitutional Court as amended under Organic Law n o. 6/2007 of 24 May 2007, provides :

“ 1. V iolations of rights and freedoms which are open to an amparo appeal and which derive immediately and directly from an act or omission on the part of a judicial body may give rise to such an appeal, subject to the following conditions:

( a ) that all the legal remedies provided for by procedural rul es have been exercised in the practical cas e, through judicial channels ... ”.

C. A pplicable law regarding upper limits on and the grouping together of sentences in Spain

71 . The relevant provision of the 1973 Penal Code in force at the time of commission of the offences in issue read :

Article 70

“ Where all or some of the sentences ( penas ) ... cannot be served simultaneously by the con victed person , the follow rules will apply :

1. Sentences ( penas ) s hall be imposed in accordance with their respective severity such that the con victed person serves them one after another, whereby the execution of a sentence shall begin , as far as possible, whe n the previous sentence has been served or been the subject of a pardon ...

2. No twithstanding the foregoing rule , the maximum prison term ( condena ) to be served by the con victed person cannot exceed three times the length of the heavi est of the sentences ( penas ) imposed , the remainder of which shall lapse as soon as the maximum term , which cannot exceed thirty years, has been reached .

The thirty-year maximum shall apply even if the sentences ( penas ) were imposed in the framework of separate sets of proceedings , provided that the connection between the offences concerned was such that they could have been the subject of one single set of proceedings . ”

72 . The relevant provision of the Criminal Procedure Act ( Ley de Enjuiciamiento Criminal ) in force at the material time provided :

Article 988

“ ... where a person found guilty of several criminal offences w as con victed in the framework of separate sets of proceedings of offences which could have been covered by the same proceedings pursuant to section 17 of this Act, the judge or court which delivered the latest judgment shall fix, proprio motu or at the request of the public prosecutor ’ s office or the con victed person , the maximum prison term for serving the sentences imposed in pursuance of A rticle 70.2 of the Criminal C ode. ... ”

D. Framework Decision no. 2008/675/JAI of the Council of the European Union of 24 July 2008 on taking account of convictions in the Member States of the European Union in the course of new criminal proceedings

73 . Framework Decision n o. 2008/675/JAI, which was adopted by the Council of the European Union o n 24 July 2008 (JO L 220/32, 15/08/2008, pp. 32-34), came into force on 15 August 2008. A rticle 5 § 1 require d EU Member States to t a ke the necessary measures to comply with the provisions of the instrument by 15 August 2010.

74 . The relevant part s of the preamble to the Framework Decision read as follows :

“6. In contrast to other instruments, this Framework Decision does not aim at the execution in one Member State of judicial decisions taken in other Member States, but rather aims at enabling consequences to be attached to a previous conviction handed down in one Member State in the course of new criminal proceedings in another Member State to the extent that such consequences are attached to previous national convictions under the law of that other Member State.

...

7. The effects of a conviction handed down in another Member State should be equivalent to the effects of a national decision at the pre-trial stage of criminal proceedings, at the trial stage and at the time of execution of the sentence.

8. Where, in the course of criminal proceedings in a Member State, information is available on a previous conviction in another Member State, it should as far as possible be avoided that the person concerned is treated less favourably than if the previous conviction had been a national conviction.

9. Article 3(5) should be interpreted, inter alia , in line with recital 8, in such a manner that if the national court in the new criminal proceedings, when taking into account a previously imposed sentence handed down in another Member State, is of the opinion that imposing a certain level of sentence within the limits of national law would be disproportionately harsh on the offender, considering his or her circumstances, and if the purpose of the punishment can be achieved by a lower sentence, it may reduce the level of sentence accordingly, if doing so would have been possible in purely domestic cases. ”

75 . The relevant parts of Article 3 of the Framework Decision , titled “ Taking into account, in the course of new criminal proceedings, a conviction handed down in another Member State ” , provide :

“ 1. Each Member State shall ensure that in the course of criminal proceedings against a person, previous convictions handed down against the same person for different facts in other Member States, in respect of which information has been obtained under applicable instruments on mutual legal assistance or on the exchange of information extracted from criminal records, are taken into account to the extent previous national convictions are taken into account, and that equivalent legal effects are attached to them as to previous national convictions, in accordance with national law.

2. Paragraph 1 shall apply at the pre-trial stage, at the trial stage itself and at the time of execution of the conviction, in particular with regard to the applicable rules of procedure, including those relating to provisional detention, the definition of the offence, the type and level of the sentence, and the rules governing the execution of the decision .

...

5. If the offence for which the new proceedings being conducted was committed before the previous conviction had been handed down or fully executed, paragraphs 1 and 2 shall not have the effect of requiring Member States to apply their national rules on imposing sentences, where the application of those rules to foreign convictions would limit the judge in imposing a sentence in the new proceedings.

However, the Member States shall ensure that in such cases their courts can otherwise take into account previous convictions handed down in other Member States . ”

76 . In its 2 June 2014 report on the implementation by Member States of Framework Decision n o. 2008/675/JAI (COM(2014) 312 final), the European Commission n ot e d that six Member States , including Spain , had not yet notified it of the measures transposing the obligations laid down in this instrument. With reference to A rticle 3 § 5 of the Framework Decision , the European Commission pointed out that the implementation of that provision would have to be assessed in the light of national criminal law principles and procedures related specifically to imposing sentences (e.g. aggregated sentences) .

77 . Framework decisions taken on the basis of Title VI of the version of the Treaty on European Union as amended by the Treaty of Amsterdam are binding on Member States as regards the required outcome , leaving to the national authoriti es the choice of form and methods . Such decisions cannot induc e any direct effect ( A rticle 34 § 2 ( b) from the Treaty on European Union , in its version amended by the Treaty of Amsterdam). According to the case-law of the CJ E U ( case of Pupino , judgment of 16 June 2005, C-105/3), the binding nature of such framework decisions imposes on the national authorities , and in particular the national court s , an obligation of interpretation in conformity with national law . In applying national law , a national court called upon to interpret the latter is required to do so as far as possible in the light of the wording and purpose of the framework decision in order to achieve the outcome pursued by that decision . This obligation ceases where national law cannot be the subject of a mode of application leading to a result compatible with that pursued by the framework decision . In other words , the compatible interpretation principle cannot serve as the basis for an interpretation contra legem of national law . That principle nevertheless requires the national court to take account, where appropriate , of national law in its entirety in order to assess the extent to which it can be appli ed in such a way as to avoid a result contrary to that pursued by the framework decision .

E. Organic Law n o. 7/2014 of 12 November 2014 on the exchange of information from police records and taking account of criminal court decisions in the EU

78 . The draft legislation which gave rise to Organic Law n o. 7/2014 on the exchange of information from police records and taking account of criminal court decisions in the EU was tabled in Parliament ( the Cortes Generales ), before the Congress of Deputies , on 14 March 2014. I t was published in the Parliament ’ s Official Gazette on 21 March 2014. The relevant provisions of the bill underwent several amendments during the enactment procedure in the Senate , between September and October 2014. The Organic law was final ly approved by the Congress of Deputies , with the Senate ’ s amendments , on 30 October 2014.

79 . Organic Law no . 7/2014 was enacted on 12 November 2014 and published in the S tat e Official Journal the next day. It came into force on 3 December 2014. It transposed Framework Decision no. 2008/675/JAI into Spanish law ( see paragraphs 73-75 above ).

80 . The relevant part s of the explanatory memorandum to Organic Law no. 7/2014 read as follows :

“ The regulations set out in Title II of this law pre suppose official recogni tion of the principle of equivalence between judgments delivered within the European Union by taking them into account in subsequent proceedings held following the commission of fresh offences . That means that, like previous con vic tions handed down in Spain , sentences imposed in another Member State must be taken into account [ at whatever sta g e], whether during the preliminary phase of criminal proceedings , the criminal proceedings themselves, or the sentence-enforcement phase . The effects of taking such sentences into account are confined to those attach ing to a con vic tion handed down in Spain , and are , moreover , subject to the condition that the con vic tion in another Member State was handed down in respect of acts punishable under Spanish la w as in force at the date of their commission.

Recognition of the effects concerns not only the time of imposition of the sentence, but also the decisions which must be taken during the investigatory and sentence-enforcement phases, for example decisions on the pre-trial detention of a suspect, on the amount of bail, on the calculation of the sentence, on a stay of execution or a revocation of such stay, or on release on licence .

With this general principle , in order to reinforce legal certainty, the law lists, pursuant to the provisions and options laid down in the Framework Decision , the cases in which such con vic tions [ handed down in another Member State ] cannot be taken into account : where previous con vic tions in Spain or decisions given with a view to their enforcement must be reconsidered ; where con vic tions likely to be handed down at a later date in Spain are given in respect of offences committed before the sentence could be imposed by the other Member State ; and in cases of decisions relati ng to the determination of the maximum prison term in respect of sentences imposed pursuant to section 988 of the Criminal Procedure Act, where one such sentence is inc orporated .

... ”

81 . The relevant provisions of Organic Law n o. 7/2014 read as follows :

Article 14 Legal effects attach ing to previous con vic tions under the new criminal procedure

“ 1. Previous final con vic tions handed down in other Member States in respect of a person for a different offence will , on the occasion of fresh criminal proceedings , the same legal effects as those attach ing to a con vic tion handed down in Spain , subject to the following conditions:

( a) the convictions must have been handed down for acts which were punishable under Spanish la w as in force at the time of their comm ission ;

( b) sufficient information on the con vic tions must have been obtained under the instruments applicable to legal mutual assistance or the exchange of information from police record s.

2. Notwithstanding the provisions of the previous sub-paragraph, final convictions handed down in other Member States will have no effect on the following, nor can they lead to their revocation or reconsideration:

( a) final judgments delivered previously by Spanish judges and courts, and decisions adopted for their enforcement ;

( b) convictions handed down during subsequent proceedings conducted in Spain for offences committed before any con vic tion has been handed down by the courts in the other Member State ;

( c) decisions which have given or are to be given in pursuance of the provisions of section 988 (3) of the Criminal Procedure Act , fixing the maximum prison term for grouping together sentences, including any conviction of the type set out in sub- paragraph ( b) above .

... ”

Single additional provision . Con vic tions prior to 15 August 2010

“ Account will not be taken, for the purposes of the present l aw, of con vic tions handed down by a court in any Member State of the European Union prior to 15 August 2010. ”

F. Case-law of the Supreme Court on the grouping together of sentences imposed and served in another S tat e

82 . By judgment n o. 2117/2002 of 18 December 2002, the Supreme Court rejected the possibility of taking into account a sentence already served in France for the purposes of implementing the maximum prison term in Spain . I t considered that the various offences which had been committed in France and Spain could not possibly have been the subject of the same criminal proceedings , since they had occurred in different national territories , subject to the sovereignty of different S tat e s, and had consequently been prosecuted before different national courts .

83 . By judgment n o. 186/2014 of 13 March 2014 the Supreme Court ( a five-judge criminal division ) considered the possibility of grouping together a sentence already served in France with subsequent sentences imposed in Spain f or different offence s, for the purposes of implementing the maximum prison term established by the Spanish Penal Code ( thirty years ). I t accepted that possibility , in the light of Framework Decision n o. 2008/675/JAI and in the absence , at the time, of domestic legislation transposi ng that Framework Decision or rules exp licitly governing that subject matter . The Supreme Court held as follows :

“ ... the existence of a European area of freedom , security and justice, which, in a way, implies separate consideration of specific aspects relating to the exercise of sovereignty . Accordingly , Framework Decision n o. 2008/675/JAI of the Council of the European Union, which was adopted on 24 July 2008 and therefore subsequently to our judgment of 18 December 2002, stated that its aim was to establish a minimum obligation on Member States to take outside of convictions handed down in other Member States . A rticle 3 of the Framework Decision provided : ‘ 1. Each Member State shall ensure that in the course of criminal proceedings against a person, previous convictions handed down against the same person for different facts in other Member States, in respect of which information has been obtained under applicable instruments on mutual legal assistance or on the exchange of information extracted from criminal records, are taken into account to the extent previous national convictions are taken into account, and that equivalent legal effects are attached to them as to previous national convictions, in accordance with national la w . 2. Paragraph 1 shall apply at the pre-trial stage, at the trial stage itself and at the time of execution of the conviction, in particular with regard to the applicable rules of procedure, including those relating to provisional detention, the definition of the offence, the type and level of the sentence, and the rules governing the execution of the decision . ’

Regardless of the Spanish Stat e ’ s diligence , as an EU Member State, in implementing the provisions of A rticle 5.1 of the aforementioned Framework Decision ( ‘ 1. Member States shall take the necessary measures to comply with the provisions of this Framework Decision by 15 August 2010 ’ ), the fact is that in the absence of rules explicitly governing the present subject matter in any categorical manner, the current regulations must be interpreted in a manner as compatible as possible with the content of European regulations, the transposition of which into the domestic system is an obligation entered into by the Spanish State on becoming a member of the European Union.

Therefore , there is nothing to prevent taking into account the judgment delivered in France for the purposes of grouping sentences together . ”

84 . In accordance with the approach thus followed by the Supreme Court in its judgment n o. 186/2014, some sections of the Criminal Division of the Audiencia Nacional have decided , in calcul ating the maximum thirty-year prison term, to deduct sentences imposed and served in France. The decisions given by that court concerning the three applic ants in the present case followed the same reasoning ( see paragraphs 16, 39 and 61 above ). Those decisions did not become final, since they were set aside by the Supreme Court following the appeals on points of law lodged by the public prosecutor ’ s office for the purposes of clarifying the la w . Moreover , i t transpires from the information s upplied by the parties that in three different cas es concerning other defendants, the sectional decisions in their favour were not the subject of an appeal on points of law and therefore became res judicata ( two decisions of 9 June 2014 and one decision of 24 November 2014).

85 . B y judgment no. 874/2014 of 27 January 2015, the Plenary Criminal Division of the Supreme Court ( comprising fifteen judges) discounted the possibility of grouping together sentences imposed and served in another EU Member State with sentences handed down in Spain for the purposes of determining the maximum prison term. The Division ’ s reasoning largely served as the basis for that adopted by the Supreme Court in its judgments on points of law relating to the three applic ants in the instant case. The main lines of that reasoning are summarised in the “ Facts ” section on the first applic ant ( see paragraphs 20-24 above ). Judgment n o. 874/2014 was adopted by a majority of nine vo tes to six. Four judges appended dissenting opinions .

G. Case-law of the Constitutional Court

86 . By judgment of 19 December 2013 (n o. 216/2013) the Constitutional Court ( Plenary formation ) clarified the criteria for determining when an action for annul ment was a judicial remedy which had to be exercis ed by a litigant before lodging an amparo appeal , pursuant to section 44 ( 1 ) ( a) of the Organic Law on the Constitutional Court . I t held that such an action did not have to be lodged where the judicial authorities had already had an opportunity to decide on the fundamental rights subsequently relied on in the framework of the amparo appeal . The Constitutional Court considered that the aim of the rule on exhaustion of available domestic remedies was to preserve the subsidiary nature of the amparo remedy , so that the ordinary courts could consider and, where appropriate , remedy the alleged fundamental rights violations. The Constitutional Court pointed out that this reasoning also appli ed in cases where the rights violation had originated in a single judicial decision given by a court at first instance and where the subject matter of the dispute before that court had entailed assessing the alleged violation of the fundamental right in issue . In that cas e , the aim of bringing an action for annul ment would merely be to seek a r e- examin ation of the merits of the decision by the same court, on the basis of arguments analogous to those used during the main proceedings .

87 . Furthermore , by reasoned decision ( auto ) of 20 September 2016, the Constitutional Court ( plenary formation) determined the amparo appeal lodged against judgment n o. 874/2014 of the Supreme Court . The court held that the Supreme Court had not retroactively appli ed Organic Law n o. 7/2014 – which had entered into force after the applicant ’ s request to group his sentences together – but had mentioned it solely in order to back up its interpretation of Framework Decision n o. 2008/675/JAI, particularly in relati on to the exception set out in A rticle 3 § 5 of that legal instrument. As regards the allegation of possible retroactive application of case-law unfavourable to the con victed person , the Constitutional Court drew a distinction between the case in question and Del Río Prada . It noted that when the total sentence to be served had been fixed in 2007 and throughout the execution of the sentence i n Spain , the applicant had obtained no decision in favour of taking account of the sentence served in France. T he court therefore considered that criminal legislation had been appli ed clearly and in complete conformity with existing judicial practice , without ever encouraging the applicant to hope that the sentence which he had served in France would be taken into account in determining the maximum prison term in Spain . I t noted that the only requests which the applicant had submitted for such an eventuality had been in 2013, that is to say after the 2007 decision to group decisions together , and they had all been dismissed . It consequently considered that in the instant case there had been no retroactive application of an unfavourable interpretation inconsistent with the judicial practice applicable a t the time when the sentence had been determined. The Constitutional Court noted that the applicant had only claimed that a possible interpretation of a previous legal rule, that is to say the rule laid down in judgment n o. 186/2014 of the Supreme Court, had been applied to him retroactively . In fact, under the principle of equality before the law, it had noted that that interpretation – adopted by a five-judge section of the Supreme Court the first time that court had been called upon to adjudicate on the Framework Decision – had remained isol ated and been rejec ted a few months later by the Plenary Supreme Court in its judgment n o. 874/2014. Moreover, the Constitutional Court observed that the detailed reasoning of that judg ment had not been based on an arbitrary or unreasonable interpretation of the applicable legislation . For all those reasons it declared the amparo appeal i nadmissi ble, since there had manifestly been no violation of the fundamental rights relied upon ( including the principle that only a statute can define offences and lay down penalties, the right to liberty, the right to equality before the law , the right to equality before the law ).

88 . That decision gave rise to two dissenting opinions by four judges of the Constitutional Court . In one dissenting opinion, two judges held that the Constitutional should have declared the appeal admissi ble and adjudicated on the merits with a judgment . In the other dissenting opinion, two judges also held that there had been a violation of the right to liberty and the principle that only a statute can define offences and lay down penalties, given that, in their view, the applicant had suffered the retroactive application of an unfavourable rule extending his prison term .

H. C ivil Code

89 . Article 1 of the C ivil Code provides :

“ 1. The sources of the Spanish legal system are the law, custom and the general principles of law.

...

6. Case-law complements the legal system with the doctrine regularly established by the Supreme Court in its interpretations and applications of the la w , custom and the general principles of law . ... ”

THE LAW

90 . Having regard to the similar subject matter of the applications, the Court finds it appropriate to join them and examine them jointly in a single judgment.

91 . The applicants complained that the decisions of the Constitutional Court declaring their amparo appeals inadmissible deprived them of their right of access to a court. They relied on Article 6 § 1 of the Convention, which reads as follows:

“ In the determination of his civil rights and obligations or of any criminal charge against him, everyone is entitled to a fair ... hearing ... by an independent and impartial tribunal established by law . ”

92 . The Government contested that argument.

93 . Th e Government objected that the available domestic remedies had not been exhausted .

94 . The Court r eiterates that under A rticle 35 § 1 of the Convention, an application can be lodged only after domestic remedies had been exhausted. In the present case the Government seems to be requesting a declaration of inadmissibility of the complaint on the same grounds as justified, in the Court ’ s view, the communication of the complaint in question, that is to say the reason for which the Constitutional Court declared the amparo appeal i nadmissi ble. The Court considers therefore that that objec tion is closely linked to the merits of the complaint put forward by the applic ants under A rticle 6 of the Convention, and decides to join it to the merits ( see , to that effect , Ferré Gisbert v . Spain , n o. 39590/05 , § 20, 13 October 2009 ). The Court notes that this complaint is not manifestly ill-founded within the meaning of Article 35 § 3 (a) of the Convention. It further notes that it is not inadmissible on any other grounds. It must therefore be declared admissible.

1. The parties ’ submissions

95 . The applic ants complained that the Constitutional Court had dismissed their amparo appeals for failure to file an action for annul ment with the Supreme Court , thus pre clud ing their examin ation on the merits . They exp lained that the Supreme Court had itself exp licitly stated in its noti ces accompanying the impugned judgments on points of law that the latter were open to an amparo appeal to the Constitutional Court within thirty days. The first and second applic ants a dded that their actions for annul ment had been declared i nadmissible by the Supreme Court on the grounds that their complaints had already been examined in the judgments concluding their respective appeals on points of law. They therefore saw a blatant contradiction between the Supreme Court and the Constitutional Court , submitting that the interpretation effected by the latter of the admissibility criteria had been excessive ly formalistic and strict .

96 . Th e Government conteste d that argument . They submitted that following the 2007 reform of the Organic Law on the Constitutional Court the scope of the action for annul ment had been broadened in order to allow litigants to complain of any fundamental rights violation before the ordinary courts before lodging an amparo appeal with the Constitutional Court . That appli ed, in particular , to the instant case, in which the alleged fundamental rights violation had occurred on one single occasion before the Supreme Court , which was at the summit of the ordinary judicial system . In that connection, th e Government relied on judgment n o. 216/2013 of 19 December 2013 of the Constitutional Court ( see paragraph 86 above ). They pointed out that that court had declared the amparo inadmissible f or failure to exercise the action for annul ment before the ordinary court s. Furthermore, in the case of the applic ant, his lawyer had not even lodged an action for annul ment and, in the case of the other two applic ants, their lawyers had requested the withdrawal of the actions which they had lodged with the Supreme Court . According to the Government , the applic ants had deliberately triggered the declaration of the inadmissibility of their amparo appeals by the Constitutional Court without giving it an opportunity to consider their allegations of fundamental rights violations , which ran counter to the subsidiarity principle .

97 . Th e first applic ant r eplied that the Constitutional Court judgment cited by the Government supported the applicant party ’ s argument : that judgment clearly stated that where a court had had an opportunity to adjudicate on the fundamental rights subsequently relied u pon before the Constitutional Court , it was no longer necessary to file an action for annul ment before th e latter court . He added that already in his reply to the appeal on points of law lodged by the public prosecutor ’ s office with the Supreme Court he had referred to the fundamental rights violations which the admission of the public prosecutor ’ s appeal would i nvolve .

2. The Court ’ s assessment

98 . The Court r eiterated that the “right to a court”, of which the right of access is one aspect (see in particular Golder v. the United Kingdom , 21 February 1975, § 36, Series A no. 18), is not absolute; it is subject to limitations permitted by implication, in particular where the conditions of admissibility of an appeal are concerned, since by its very nature it calls for regulation by the State, which enjoys a certain margin of appreciation in this regard ( see García Manibardo v . Spain , n o. 38695/97, § 36, E CH R 2000-II, and De la Fuente Ariza v. Spain , n o. 3321/04, § 22, 8 November 2007). Nonetheless, the limitations applied must not restrict the access left to the individual in such a way or to such an extent that the very essence of the right is impaired. Furthermore, a limitation will not be compatible with Article 6 § 1 if it does not pursue a legitimate aim and if there is not a reasonable relationship of proportionality between the means employed and the aim sought to be achieved ( see Zubac v . Croatia [GC], n o. 40160/12, § 78, 5 April 2018, and Arribas Antón v . Spain , n o. 16563/11 , § 41, 20 January 2015). The right of access to a court is impaired when the rules cease to serve the aims of legal certainty and the proper administration of justice and form a sort of barrier preventing the litigant from having his or her case determined on the merits by the competent court ( see Kart v. Turkey [GC], n o. 8917/05, § 79, E CH R 2009 ( extracts )).

99 . The Court also r eiterates that Article 6 of the Convention does not compel the Contracting States to set up courts of appeal or of cassation and , e ven less , courts with jurisdiction to deal with amparo appeals . However, where such courts do exist, the State must ensure that they provide litigants with access to the fundamental guarantees of Article 6 ( see Zubac , cited above , § 80, and Arribas Antón , cited above , § 42). Furthermore , the compatibility of limitations laid in domestic law with the right of access to a court as secu re d by Article 6 depends on the specific features of the proceedings in issue . The Court has several times found that the imposition by the national courts of compliance with formalities in order to lodge an appeal is liable to breach the right of access to a court. This is the case when an excessively formalistic interpretation of a legal provision prevents de fa c t o the consideration of the merits of a remedy exerc ised by a litigant ( see , fo r example , Zvolský and Zvolská v . the Czech Republic , n o. 46129/99, §§ 48 ‑ 55, E CH R 2002 ‑ IX ; De la Fuente Ariza , cited above , §§ 24-28 ; and Ferré Gisbert , cited above , §§ 28-33). Regard should be had to the domestic proceedings as a whole and to the role played in them by the Constitutional Court , although the conditions for the admissibility of an amparo appeal may be stricter than in the case of an ordinary appeal ( see Arribas Antón , cited above , § 42).

100 . Finally, the Court reiterates the fundamental principle that it is for the national authorities , particularly the courts, to interpret and apply domestic law ( see Brualla Gómez de la Torre v . Spain , 19 December 1997, Re ports of Judgments and Decisions 1997-VIII, § 31). T he Court will not therefore question the judgment of the national courts as regards alleged errors of law, unless their findings can be regarded as arbitrary or manifestly unreasonable ( see, to that effect, Bochan v . Ukraine (n o. 2) [GC], n o. 22251/08, § 61, E CH R 2015).

101 . I n the present case , the Court observe s that the Constitutional Court ’ s decision of 24 May 2016 ( concerning the first applic ant) and those of 22 June 2016 ( concerning the second and applic ants) declared i nadmissible the amparo appeals lodged by the applic ants against the Supreme Court ’ s judgments rejecting the possibility of grouping together sentences served in France with sentences imposed in Spain . Those decisions were based on the grounds of inadmissibility set out in section 44 ( 1 ) ( a) of the Organic Law on the Constitutional Court , that is to say non- exhaustion of ordinary legal remedies : in the present case the Supreme Court criticised the applic ants for failing to lodge an action for annul ment under section 241 ( 1 ) LOPJ.

102 . The Court note s that the first two applic ants did in fact lodge action s for annul ment with the Supreme Court , requesting urgent procedure so that they could lodge an amparo appeal with the Constitutional Court within the thirty-day legal time-limit from the date of notification of the cassation judgments . It is true that those two applicants subsequently withdrew their actions for annulment before applying to the Constitutional Court, but the Supreme Court nonetheless served them with a decision declaring the actions inadmissible as irrelevant. That decision was served after the expir y of the thirty-day legal time-limit for lodging the amparo appeal and after the applicants in question had lodged that appeal with the Constitutional Court ( see paragraphs 31 and 50 above ). I t should be noted that the notices accompanying the cassation judgments on 10 April 2015 explained that the latter were final but that an amparo appeal lay with them before the Constitutional Court within a thirty-day time-limit. There is nothing to suggest that that time-limit had been suspended by the lodging of the actions for annulment . If the two applic ants had awaited notification of the decisions concerning their actions for annul ment before preparing and validly lodging their amparo appeal , there would have been nothing to prevent the Constitutional Court from subsequently declaring their appeals i nadmissible as being out of time, on grounds of the irrelevance of the actions for annul ment ( see , fo r example , Del Pino García and Ortín Méndez v . Spain ( d e c. ), n o. 23651/07, § 32, 14 June 2011).

103 . Furthermore , the Court notes that the Constitutional Court decisions concerning the first and second applic ants are inco nsistent with the decisions of the Supreme Court declaring i nadmissible as irrelevant the actions for annul ment lodged by those applic ants. Indeed , the Supreme Court held that most of the complaints put forward by the two applic ants had already been examined in the impugned cassation judgments , and that pursuant to section 241 ( 1 ) LOPJ the actions for annul ment had therefore to be declared i nadmissible . The Court observe s that those remedies had already been the subject of a thorough assessment in the framework of the cassation proceedings ( see paragraphs 23-24 above ). Moreover, this was the position defended by the two applic ants in their amparo appeals with regard to the legal requirement of exhaustion of available remedies ( see paragraphs 30 and 49 above ).

104 . C l e a r ly , i t is not the Court ’ s task to determine the question whether an action for annul ment was an appropriate remedy under domestic law in these circumstances . However, the Court considers that the reasoning of the impugned decisions of the Constitutional Court is inco nsistent with that of the previous decisions given by the Supreme Court on the irrelevance of the actions for annul ment .

105 . The Court notes that the third applic ant, unlike the first and second applic ants, did not file an action for annul ment with the Supreme Court before lodging an amparo appeal with the Constitutional Court . It should nevertheless be noted that , since he was represented by the same solicitor as the first and second applic ants, he could have been apprised of the declaration of inadmissibility of the actions for annul ment lodged by the other applic ants before the expir y of the thirty-day time-limit for lodging an amparo appeal . In those circumstances , that applic ant and his representative could reasonably have foreseen that if he were to file an action for annul ment with the Supreme it would also fail. The third applic ant cannot therefore be accused of having direct ly lodged an amparo appeal with the Constitutional Court, especially since in his appeal he, like the other applic ants, pointed out that the Supreme Court , which had originated the impugned cassation judgment , had already adjudicated on all the allegations of fundamental rights violations which he was submitting to the Constitutional Court , and that he had therefore exhausted all the available legal remedies ( see paragraph 67 above ).

106 . The Court attaches particular importance to whether the procedure to be followed for an action for annulment as a remedy to be used before applying to the Constitutional Court could be regarded as foreseeable from the litigants ’ point of view (see, as regards the requirement of foreseeability of a restriction on access to a higher court, Zubac , cited above, §§ 87-89). It notes in that regard that the Government relies on a Constitutional Court judgment of 2013 establishing the criteria for determining when the exercise of an action for annul ment was required before an application to that higher court ( see paragraph 86 above ). The Court note s, however, that that judgment stated that the u se of such an action was not required where the court having originated the impugned judicial decision given at first instance had already adjudicated on the allegations of fundamental rights violations which were subsequently to be put forward in the framework of the amparo appeal . That was precisely the situation in the present case , as noted by the Supreme Court in its decisions declaring the first and second applicants ’ actions for annul ment inadmissible . Accordingly , the Constitutional Court ’ s subsequent decisions were not foreseeable or consistent with the case-law relied upon by the Government .

107 . In the light of all those facts, the Court considers that a disproportionate burden was imposed on the applic ants , thus upsetting the requisite fair balance between, on the one hand, the legitimate aim of ensuring compliance with the formal conditions for applying to the Constitutional Court, and on the other , the right of access to that court . In the present case , the fact that the amparo appeals had been declared i nadmissi ble on grounds of non- exhaustion of available domestic remedies , even though the Supreme Court had previously declared the first and second applic ants ’ actions for annulment i nadmissible as irrelevant and had served the litigants with its decisions outside the thirty-day time-limit for lodging an amparo appeal , must at the very least be considered as creating legal un certainty to the applic ants ’ detriment ( see , mutatis mutandis , Ferré Gisbert , cited above , § 33).

108 . The Court consequently holds that the inadmissibility decisions regarding the amparo appeals for non- exhaustion of available domestic remedies deprived the applic ants of their right of access to a court .

109 . The Court therefore rejects the Government ’ s objection and finds a violation of A rticle 6 § 1 of the Convention.

110 . The applic ants complain ed of what they saw as the retroactive application of new Supreme Court case-law and of a new law which had come into force after their con vic tion , arguing that this had prolonged the actual length of their prison term s . They relied on A rticle 7 of the Convention, the relevant parts of which provi d e :

“ 1. No one shall be held guilty of any criminal offence on account of any act or omission which did not constitute a criminal offence under national or international law at the time when it was committed. Nor shall a heavier penalty be imposed than the one that was applicable at the time the criminal offence was committed.

... ” .

111 . Th e Government contested that argument .

A. Admissibility

112 . Th e Government plead ed a failure to exhaust domestic remedies . They submitted that the available remedies had not been properly exhausted because the applicants ’ amparo appeals had been declared i nadmissible by the Constitutional Court on grounds of non- exhaustion of available remedies . The applicants therefore stood accused of failure to comply with the requisite legal form aliti es and conditions for the admissibility of a domestic remedy .

113 . Th e Government considered that the issue arising in the present case related exclusive ly to the enforcement of the l awfully imposed sentences, which issue was not covered by A rticle 7 of the Convention. They stated that the sentences imposed on the applicants had totalled over three thousand years ’ imprisonment (for the first applicant), forty ‑ six years ’ imprisonment (for the second applicant) and over four thousand seven hundred years ’ imprisonment (for the third applicant), respectively. The implement ation of the maximum thirty-year prison term was aimed at restricting or setting an upper limit on the actual period of imprisonment under sentences already imposed . Furthermore, implementing the maximum prison term pre suppose d the remission of a large number of sentences imposed for conne cted offenc es. Th e Government relied in that regard on the judgment in the case of Kafkaris v. Cyprus ([GC], n o. 21906/04, § 142, 12 February 2008) as regards the distinction between a measure constitu ting a “ sentence ” and a measure relati ng to the “ execution ” or “ enforcement ” of a “ sentence ” . They therefore invite d the Court to declare that complaint inadmissible as incompatible ratione materiae .

114 . The applic ants replied that they had exhausted all the existing domestic remedies in conformity with the subsidiarity principle .

115 . They submitted that the issued raised by their case went beyond mere sentence enforcement . They took the view that refusing to group together the sentences served in France for the purposes of implementing the maximum prison term in Spain had led to a redefinition of the scope of the “ sentences ” imposed , bringing it within the ambit of A rticle 7 of the Convention.

116 . The Court notes that the first objec tion is closely linked to the substance of the applic ants ’ complaint under A rticle 6 § 1 of the Convention. In the light of the considerations which led it to find a violation of that provision ( see paragraphs 101-109 above ), the Court considers that the applic ants gave the domestic courts an opportunity to provide redress for the alleged violation , and concludes that it must reject the Government ’ s objection as to failure to exhaust domestic remedies .

117 . As regards the second objec tion as to inadmissibility , the Court considers that it is closely linked to the substance of the applicants ’ complaint under A rticle 7 and decides to join it to the merits ( see , mutatis mutandis , Gurguchiani v . Spain , n o. 16012/06, § 25, 15 December 2009).

Further noting that that complaint is not manifest ly ill- founded within the meaning of A rticle 35 § 3 ( a) of the Convention and that it is not inadmissible on any other grounds, the Court declares it admissi ble.

B. The merits

1. The parties ’ submissions

118 . The applicants submitted that the application in their cases of the case-law reversal effected under judgment no. 874/2014 of the Supreme Court and under Organic Law no. 7/2014, which had come into force after their con vic tion and their requests to group together the sentences served in France, had actual ly prolonged their prison sentences . The application of that case-law reversal , which had been detrimental to their interests , had been unforeseea ble and retroactive . The applic ants exp lained that when they had submitted their requests to group together the sentences served in France they had been unable , in the light of domestic law as a whole, to foresee the legislative change s that would stem from Organic Law n o. 7/2014 and the Supreme Court ’ s case-law reversal . They added that the justification for this reversal had been the sp i rit of Organic Law n o. 7/2014, which the Supreme Court had de facto appli ed retroactively .

119 . Th e Government considered that the applic ants or their lawyers could not have expected – before the adoption of Framework Decision n o. 2008/675/JAI – that there was any possibility of the sentences imposed in France be ing grouped together with the sentences to be served in Spain for the purposes of determining the maximum prison terms to be served . Nor could they have foreseen such a possibility before the date scheduled for the transposition into national law of the Framework Decision (15 August 2010), or between that date and the date of publication of the draft transposition legislation (21 March 2014). Indeed, the Government pointed out that when the Supreme Court had delivered its i sol at e d judgment n o. 186/2014 ( on 13 March 2014), none of the three applic ants had submitted any request under the Framework Decision for grouping together the sentences served in France. They added that once the draft transposition legislation had been tabled , the applic ants and their lawyers had known that they would have to comply with its provisions . Furthermore, the Government stated that before the enactment and entr y into force of Organic Law n o. 7/2014 (on 3 December 2014), the only established Supreme Court case-law was that prohibiting the grouping together of sentences imposed in France. Furthermore, the decisions of the Audiencia Nacional in the three applicants ’ favour had been given one day before the entry into force of that law and had been immediately challenged before the Supreme Court, and the latter had quashed and annulled them in line with the approach adopted in its leading judgment no. 874/2014 of 27 January 2015, which was adopted by the plenary court. The Government explained that that Supreme Court judgment dis pelled any doubts which might have arisen as regards the validity of its previous line of authority .

120 . Th e Government drew a distinction between the present case and Del Río Prada. They took the view that in the instant case the pre-existing legislation and the Supreme Court case-law had been clear: unless there was an international treaty which was in force and had been transposed into domestic law, sentences imposed abroad were not taken into account for the purposes of the determination of the maximum prison term. T hey held that it was impossible to claim that judgment n o. 186/2014 could have created “ certainty ” in the applic ants ’ or their lawyers ’ minds as regards the change in the applicable legislation , because it was a case of one isolated judgment of the Supreme Court which had not set a precedent and had given rise to contradictory decisions in the different sections of the Audiencia Nacional based on an EU Framework Decision currently in the process of transposition. The judgment had been delivered during the proce dure for enacting the transposition bill at parliamentary level, and had in fact been disavowed only nine months later by the plenary Criminal Division of the Supreme Court . The Government p ointed out that the applic ants had never secured a final court decision in their favour regarding the incorporation of the sentences imposed in France. Furthermore , the fact that the first and second applic ant s had been released pending the outcome of the appeals on points of law had constituted an interim measure benefiting those two applic ants.

2. The Court ’ s assessment

121 . The Court re fers to its Del Río Prada judgment , cited above , which sets out the general principles concerning A rticle 7 of the Convention (§§ 77-93). As regards , more specifically , the distinction between the concept of a “penalty” and that of measures relati ng to the “execution” of a penalty , it established in that judgment that it did not rule out the possibility that measures taken by the legislature, the administrative authorities or the courts after the final sentence has been imposed or while the sentence is being served may result in the redefinition or modification of the scope of the “penalty” imposed by the trial court. When that happens, the Court considers that the measures concerned should fall within the scope of the prohibition of the retroactive application of penalties enshrined in Article 7 § 1 in fine of the Convention ( ib id . , § 89).

122 . In the present cas e , the Court observe s from the outset that by three decisions given on 7 March 2006 ( concerning the first applic ant), 31 July 1997 ( concerning the second applic ant) and 18 November 2013 ( concerning the third applic ant), the trial courts fixed at thirty years the maximum prison terms to be served by the applic ants under the custodial sentences imposed on them under section 70.2 of the 1973 Penal Code in force at the time of the commission of the offences . In the cas e of the first and third applic ants, that measure was also the result of a decision to group together the various sentences impose d in the framework of separat e sets of criminal proceedings , having regard to the chronological connection between the offences committed , on the basis of section 988 of the Criminal Procedure Act . Under Spanish law , a sentence to be served resulting from that maximum prison term and from those decisions to group sentences together and / or set au upper limit on them was conceived of as a new independent sentence ( see , to that effect , Del Río Prada , cited above , §§ 97-99). Furthermore , it was from that latter sentence that such prison benefits as remissions of sentence ( see paragraphs 14, 41 and 59 above ; see also Del Río Prada , cited above , § 99) and periods spent in pre-trial detention were to be deducted .

123 . In the light of the foregoing considerations, the Court cannot accept the Government ’ s argument that the application of the maximum prison term laid down in the Penal Code was a measure that plac ed an upper limit on the total term of imprisonment , relating exclusive ly to the “execution” of individual sentenc es already imposed. On the contrary , it was a measure which concern ed the extent of the sentences imposed on the applic ants ( see also , as regards combining multiple sentences into an overall sentence , Koprivnikar v . Slovenia , §§ 50-52, 24 January 2017). Therefore , the impugned decisions of the Supreme Court refusing to allow the applic ants ’ requests to take account of the sentences already served in France for the purposes of the determin ation of the maximum prison term in Spain also concerned the scope of the sentences imposed, and thus fell within the ambit of the last sentence of A rticle 7 § 1 of the Convention. The Government ’ s objec tion as to incompatibility ratione materiae s h oul d therefore be rejected .

124 . The Court must now seek to establish whether the impugned decisions of the Supreme Court altered the extent of the sentences imposed on the applic ants. In doing so , it must have regard to the domestic law as a whole and to how it was applied at the material time ( see , mutatis mutandis , Del Río Prada , cited above , §§ 90, 96 and 109). However, the Court p oints out that it is not competent to decide what is the proper interpretation of domestic law in the sphere of consideration of sentences served in another EU member State or to rule formally on the question whether the Supreme Court correct ly appli ed Framework Decision n o. 2008/675/JAI or any other provision of EU law ( see , mutatis mutandis, Avotiņš v . Latvia [GC], n o. 17502/07 , § 100, E CH R 2016).

125 . In the present case the Court noted, firstly, that the impugned decisions of the Supreme Court did not alter the maxim um prison term, which has always been thirty years ’ imprisonment . The subject matter of the dispute before the Spanish courts was whether, in order to implement that maximum term, account should be taken of sentences already served by the applic ants in France under the con vic tions handed down in France f or criminal offences committed in that S tat e . The decisions given by the Audiencia Nacional in favour of taking account of those sentences never became res judicata , because the public prosecutor ’ s office appealed against them on points of law to the Supreme Court, the highest court in the Spanish judicial system , with jurisdiction to determine divergences among the lower courts in the application of the la w . Th e fact that the first and second applic ants were release d on licence pursuant to the Audiencia Nacional ’ s decisions in favour of considering the French sentences, pending the outcome of the appeals on points of law , did not alter the non - final nature of those decisions .

126 . The Court also observes that when the applicants had committed the criminal offences and when the decisions had been adopted to take account of and/or to place an upper limit on their sentences (on 7 March 2006, 31 July 1997 and 18 November 2013 respectively), the relevant Spanish law, taken as a whole – including precedent-based law – did not provide, to a ny reasonable extent, for taking account of sentences already served in another S tat e for the purposes of determining the maximum prison term in Spain . Section 988 of the Criminal Procedure Act on the consideration of sentences imposed in the framework of separate criminal proceedings did not include any specific rule on taking account of sentences imposed abroad . The only precedents in favour of such consideration of sentences concern ed sentences imposed abroad prior to being served in Spain under an international treaty on the transfer of con victed persons, bu t not sentences already complet ed abroad ( see paragraph 21 above ). In the only cas e similar to that of the applic ants ( Supreme Court judgment n o. 2117/2002, see paragraph 82 above ), the Supreme Court had refused to take into account a sentence already served in France. That lack of foreseeability might explain the fact that at the time the applic ants had not requested the consideration of the sentences served in France, even though the latter had en ded in 1995, 1996 and 2000 respective ly . Even the third applic ant, who had requested consideration of his sentence on 4 December 2012, when Framework Decision n o. 2008/675/JAI was already in force , had not referred to the sentence served in France and / or the Framework Decision ( see paragraph 57 above ). I t should be note d that under the Treaty on European Union itself , Framework Decisions could not induce any direct effect .

127 . The Court attache s importance to the fact that the three applic ants did not request consideration of their sentences served in France on the basis of Framework Decision n o. 2008/675/JAI until after the adoption on 13 March 2014 of Supreme Court judgment n o. 186/2014, that is , on 25 March 2014, 20 March 2014 and 30 April 2014 respective ly . In that judgment the Supreme Court had been called upon for the first time to interpret Framework Decision n o. 2008/675/JAI, and e ven though it had been in favour of the possibility of taking account of sentences served in another EU Member State for the purposes of grouping sentences together , it pointed out that this stance had been adopted because there was no national legislation transposing the Framework Decision or any explicit regulation on that matter ( see paragraph 83 above ). Pursuing that approach , some sections of the Criminal Division of the Audiencia Nacional have grouped sentences served in France together with sentences imposed in Spain for the purpose of determining the maximum thirty-year prison term . All these decisions , apart from three isolated case s, were set aside by the Supreme Court after the public prosecutor ’ s office had lodged appeals on points of law and after the adoption by the Plenary Criminal Division of the Supreme Court of its judgment n o. 874/2014 of 27 January 2015 ( see paragraph 85 above ). The Court observe s that under Spanish law, precedents are not a source of law and that only case-law repeatedly established by the Supreme Court can complement la w ( see paragraph 89 above ). At all events, irrespective of whether isolated judgment n o. 186/2014 of 13 March 2014 set an authoritative precedent under Spanish law ( see , mutatis mutandis , Del Río Prada , § 112), the Court considers that that judgment was not accompanied by a ju dicial or administrative practice consolidat e d over time which could have created legitimate expectation s in the applicants as regards a stable interpretation if criminal la w . The present case clearly differs in that respect from Del Río Prada , where the applicant could reasonably have thought, while she was serving her prison sentence and when the decision to combine the sentences and fix a maximum prison term was taken, that the remissions of sentence for work done in prison would be de ducted from the maximum thirty -year prison term in accordance with the established practice that had been applied consistently by the Spanish prison and judicial authorities for many years ( ib id . , §§ 98-100, 103, 112-113). It was with regard to that previous practice concerning the interpretation of criminal la w and the scope of the sentence imposed that the Court considered that the Supreme Court ’ s case-law reversal ( the “ Parot doctrine ” ) as appli ed to the applicant could not be deemed foreseea ble, and that consequently there had been a violation of A rticle 7 ( ib id . , §§ 111-118).

128 . The Court observe s that in the instant case the divergences among the different courts concerned as to the possibility of grouping together sentences served in another Member State with sentences imposed in Spain o n ly lasted for about ten months, up until the adoption by the Supreme Court of its leading judgment n o. 874/2014. It accepts that achieving consistency of the law may take time, and periods of conflicting case-law may therefore be tolerated when the domestic legal system is capable of accommodating them ( see , mutatis mutandis , Borcea v . Romania ( d e c. ), n o. 55959/14, § 66, 22 September 2015). In the present case, the highest court in Spain in matters of criminal l aw, that is to say the Supreme Court ( its plenary Criminal Division ), settled the divergence in question by adjudicating on the issue of taking account of sentences served in another EU Member State . The Court note s that the solutions adopted in the applic ants ’ cases merely followed the judgment of the plenary Supreme Court .

129 . In the light of the foregoing considerations , and having regard to the relevant domestic law in force when the applic ants committed the offences , when the decisions had been adopted to take account of and/or to place an upper limit on their sentences , and when the applicants requested consideration of the sentences served in France, the Court considers that the impugned decisions did not lead to any change in the scope of the sentences imposed . The sentences imposed were always maximum thirty-year prison terms resulting from the consideration of and / or the pla cing of an upper limit on the individual sentences imposed on the applicants by the Spanish criminal courts, without taking account of the sentences imposed and served in France.

130 . I t follows that the impugned Supreme Court decisions did not lead to any change in the extent of the sentences imposed on the applic ants. Accordingly , the Court finds that there was no violation of A rticle 7 of the Convention.

131 . The applicants further complained of the fact that their detention had been extended by twelve years (in the case of the first applicant), seven years (in the case of the second applicant) and ten years (in the case of the third applicant), respectively, owing to the retroactive application of the law to their detriment . The first and third applicants allege d that they ha d been held in unlawful and arbitrary detention since 27 January 2013 and 5 August 2016 respectively. The applic ants relied on A rticle 5 § 1 of the Convention, the relevant parts of which provide :

“ 1. Everyone has the right to liberty and security of person. No one shall be deprived of his liberty save in the following cases and in accordance with a procedure prescribed by law :

(a) the lawful detention of a person after conviction by a competent court ;

... ”

132 . The Government contested that argument .

A. Admissibility

133 . The Government raised the same preliminary objection as to non ‑ exhaustion of domestic remedies as under Article 7 (see paragraph 112 above). The applicants recorded their disagreement.

134 . T he Court ca n only refer to its previous conclusions under A rticle 6 § 1 of the Convention concerning the right of access to the Constitutional Court and the objec tion as to non- exhaustion of domestic remedies in relati on to A rticle 7 ( see paragraphs 101-109 and 116 above ). The objec tion must accordingly be rejected .

135 . Noting that that complaint is not manifest ly ill- founded within the meaning of A rticle 35 § 3 ( a) of the Convention and that it is not inadmissible on any other grounds , the Court declares it admissi ble.

B. The merits

1. The parties ’ submissions

136 . The applicants submitted that their continued detention a fter the date on which they would have completed their sentences if the Spanish courts had agreed to take into account the sentences which they had served in France could not have been “ lawful or “ in accordance with a procedure prescribed by law ” . They took the view that that continued detention was the result of the retroactive application of Organic Law n o. 7/2014 and of the Supreme Court case-law applying that law, to their detriment .

137 . Th e Government co ntested that argument. They submitted that the decisions of the Audiencia Nacional allowing the requests for consideration of the sentences served by the applic ants in France for the purposes of determin ing the maxim um prison term had been non- fin al decisions , specifying that they had all been quashed and set aside by the Supreme Court . They argue d that the fact that the applic ants had been released on licence during the cassation proceedings had merely been the result of applying domestic legislation , which, in their view, had been fully consistent with paragraphs 3 and 4 of A rticle 5 of the Convention. From the moment the Supreme Court had set aside the decisions of the Audiencia Nacional i t had been necessary to re calcul ate the sentences to be served . I n that connection, the re calcul ation had been effected on the basis of the final judgments of the Supreme Court deciding not to take account of the sentences served i n France for the purposes of determining the maximum prison term in Spain . The Government also alleged that, inasmuch as the approach followed by the Supreme Court had fully complied with the provisions of A rticle 7 of the Convention, the actual prison term should be understood as being covered by the sentences imposed in Spain and that the applicable law had been clearly foreseea ble. The Government considered that it was only i f the Audiencia Nacional ’ s decisions on the consideration of sentences had become final that the prison terms in question would not have been covered by the sentences imposed .

2. The Court ’ s assessment

138 . The Court re fers to its judgment in Del Río Prada , cited above , which sets out the relevant principles concerning A rticle 5 § 1 of the Convention, and in particular indent ( a) thereof (§§ 123-127) .

139 . In the present case , the Court has no dou b t that the applic ants were in fact con victed, after proceedings prescribed by la w , by courts which were competent within the meaning of A rticle 5 § 1 ( a) of the Convention. Moreover , the applicants do not de n y that their detention was lawful up until the dates on which they ought to have completed their respective sentence s in accordance with the decisions of 2 December 2014 of the Audiencia Nacional ( on 27 January 2013, 24 August 2013 and 5 August 2016 respective ly ), taking into account the sentences which they had served in France for the purposes of determining the maximum thirty-year prison term . I t remains to be seen whether the applicants ’ continued detention or reimprisonment after those dates was “ lawful ” within the meaning of A rticle 5 § 1 ( a) of the Convention.

140 . In the light of the considerations which have led it to find no violation of A rticle 7 of the Convention ( see paragraphs 124-130 above ), the Court considers that when the applic ants ’ sentences had been imposed, and even later, when they requested the taking into account of the sentences served in France, Spanish law had not provided , to any reasonable extent , that sentences already served in France sh ould be taken into account for the purposes of determining the maximum thirty-year prison term . Given that the impugned decisions had not led to any change, in the light of Article 7, in the extent of the sentences imposed, the prison terms impugned by the applic ants cannot be designated as unforeseeable or unauthorised by “ l aw” within the meaning of A rticle 5 § 1 ( see , to converse effect , Del Río Prada , cited above , §§ 130-131).

141 . Moreover , the Court notes that there is a causal link for the purposes of A rticle 5 § 1 ( a) of the Convention between the sentences imposed on the applic ants and their continued detention after the dates indicated by them , stemming from the guilty verdicts and the maximum thirty-year prison term established in decisions to group sentences imposed in Spain together and/or to set au upper limit on them ( see , mutatis mutandis , Del Río Prada , cited above , § 129).

142 . Accordingly , the Court considers that in the present case there has been no violation of A rticle 5 § 1 of the Convention.

143 . Article 41 of the Convention provides:

“If the Court finds that there has been a violation of the Convention or the Protocols thereto, and if the internal law of the High Contracting Party concerned allows only partial reparation to be made, the Court shall, if necessary, afford just satisfaction to the injured party.”

A. Damage

144 . The applic ants claimed compensation for the non-pecuniary damage which they had sustained solely in connection with the alleged violation of Article 7 and Article 5 § 1. Their pecuniary claims d id not concern the complaints under A rticle 6 § 1 of the Convention. The applic ants also request ed their release from prison at the earliest possible date .

145 . Having regard to the fact that it has found a violation of A rticle 6 § 1 but no violation of Article 7 and Article 5 § 1 of the Convention, the Court holds that there is no need to make any award in respect of non-pecuniary damage or to indicate individual measures to the respondent S tat e as requested by the applic ants ( see , to converse effect , Del Río Prada , cited above , §§ 137-139).

B. Costs and expenses

146 . Th e first applic ant claimed 2, 662 euros (EUR) in respect of costs and ex pens es incurred before the domestic courts and EUR 3 , 138 . 71 in respect of those incurred before the Court . He requested that the sums relati ng to unpaid invoices be paid direct ly to his representative . The second and third applic ant s claim ed EUR 2, 662 each in respect of costs and ex pens es incurred before the domestic courts and EUR 1,815 each in respect of those incurred before the Court . They requested that the awards under this head be paid direct ly into their representative ’ s bank account

147 . Th e Government submitted that under the Court ’ s case-law , claims in respect of costs appertaining to domestic proceedings should be rejected . As regards the award in respect of the costs incurred before the Court , they left that matter to the latter ’ s discretion .

148 . According to the Court ’ s case-law, an applicant is entitled to the reimbursement of costs and expenses only in so far as it has been shown that these have been actually and necessarily incurred and are reasonable as to quantum . The Court considers that in the present case th e applic ants are not entitled to the reimbursement of all the costs and ex pens es incurred for their defence before the Spanish courts, and that they are only entitled to the reimbursement of the costs required to complain of the alleged violation found by the Court. In the instant case the Court found a violation of A rticle 6 § 1 of the Convention on account of the inadmissibility decisions given on th e amparo appeals by the highest national court, that is to say the Constitutional Court , with whose decisions no further effective remedies lie ( see, fo r example , Ferré Gisbert , cited above , §§ 38 ‑ 39 and 49). The Court therefore considers that the costs appertaining to the domestic proceedings cannot be deemed to have been incurred with a view to preventing or denouncing the violation which it has found, and therefore rejects the corresponding claims .

149 . As regards the costs and expenses incurred before the Court, having regard to the documents at its disposal and to the fact that it has only found one violation of the Convention, the Court considers it reasonable to award the first applicant the sum of EUR 2,000 a nd the second and third applic ants EUR 1,000 each . Those sums are to be paid direct ly into the bank accounts of the applicants ’ representatives ( see , mutatis mutandis , Khlaifia and Others v . Italy [GC], n o. 16483/12, § 288, E CH R 2016).

C. Default interest

150 . The Court considers it appropriate that the default interest rate should be based on the marginal lending rate of the European Central Bank, to which should be added three percentage points.

FOR THESE REASONS, THE COURT, UNANIMOUSLY,

(a) that the respondent State is to pay the applicants, within three months from the date on which the judgment becomes final in accordance with Article 44 § 2 of the Convention, the following amounts:

(i) EUR 2,000 ( two thousand euros), plus any tax that may be chargeable to the first applicant, in respect of costs and expenses , to be paid directly into his representative ’ s bank account ;

(ii) EUR 1,000 (one thousand euros), plus any tax that may be chargeable to each of the second and third applicants, in respect of costs and expenses, to be paid directly into their representative ’ s bank account;

(b) that from the expiry of the above-mentioned three months until settlement simple interest shall be payable on the above amounts at a rate equal to the marginal lending rate of the European Central Bank during the default period plus three percentage points;

Done in Frenc h, and notified in writing on 23 October 2018 , pursuant to Rule 77 §§ 2 and 3 of the Rules of Court.
