44 . On 30 December 2004 the district court allowed the complaint. The court stated, inter alia , the following:

“ ... the court established that :

... from [the date of the opening of the criminal case] 29 September 2003 up to the present the investigation in criminal case no. 42172 was suspended three times and resumed twice owing to the applicants ' numerous complaints.

On 30 November 2004 the investigator Zh. U. took t he last decision to suspend the investigation for failure to establish the identities of the perpetrators ; this decision was taken by him after 25 November 2004 , that is , [shortly] after the applicants had lodged their court complaint about his actions.

Given the kind of approach the investigator has taken to the execution of his work duties, it is possible that the perpetrator s [ of the abduction] will not be established any time soon [ ... ] the investigator did not carry out the written orders issued by the deputy district prosecutor on 25 October 2004 ... even though such orders were compulsory ...

In the course of the preliminary investigation it had been unequivocally established by whom and when the Mudayev brothers had been arrested and where they had been detained. From this it follows that the investigator and the supervising prosecutor must concentrate their attention on the identif ication of those who detained the brothers , on the examination of the lawfulness and the grounds for their detention , [and] the establishment of the actual place of t heir detention, which was carried out without lawful grounds ...

The court decided:

45 . On 11 May 2005 the second applicant complained to the district court that the investigation into the abduction had been ineffective . S he described in detail the circumstances of the abduction and pointed out that Aslan and Mokhmad Mudayev had been unlawfully detained as hostages in the Nadterechniy district department of the FSB. The applicant stated that the investigation into the abduction had been suspended several times and that the last suspension had taken place on 13 May 2005. The applicant sought a ruling obliging the prosecutor ' s office to resume the investigation and transfer it to the Chechnya prosecutor ' s office.

46 . On 8 June 2005 the district court rejected the applicant ' s complaint. On 16 August 2005 this decision was upheld on appeal by the Chechnya Supreme Court.

THE LAW

They further argued that it had been open to the applicants to challenge in court any act s or omissions of the investigating or other law-enforcement authorities, and that the applicants had availed themselves of that remedy. Finally, they argued that it had been open to the applicants to pursue civil complaints but that they had failed to do so.

75 . The applicants con test ed that objection. They stated that the criminal investigation had proved to be ineffective . With reference to the Court ' s practice, they argued that they were not obliged to claim damages through civil proceedings in order to exhaust domestic remedies.

B. The Court ' s assessment

76 . The Court will examine the arguments of the parties in the light of the provisions of the Convention and its relevant practice (for a relevant summary, see Estamirov and Others v. Russia , no. 60272/00, § § 73-74, 12 October 2006).

77 . The Court notes that the Russian legal system provides, in principle, two avenues of recourse for the victims of illegal and criminal acts attributable to the State or its agents, namely , civil and criminal remedies.

78 . As regards a civil action to obtain redress for damage sustained through the alleged illegal acts or unlawful conduct of State agents, the Court has already found in a number of similar cases that this procedure alone cannot be regarded as an effective remedy in the context of claims brought under Article 2 of the Convention (see Khashiyev and Akayeva v. Russia , nos. 57942/00 and 57945/00, §§ 119-21, 24 February 2005, and Estamirov and Others , cited above, § 77 ). In the light of the above, the Court confirms that the applicants were not obliged to pursue civil remedies.

79 . As regards criminal law remedies provided for by the Russian legal system , the Court observes that the applicants complained to the law enforcement authorities about the kidnapping of Aslan and Mokhmad Mudayev and that an investigation has been ongoing since 29 September 2003 . The applicants and the Government dispute the effectiveness of the investigation of the kidnapping.

80 . T he Court considers that the Government ' s objection raises issues concerning the effectiveness of the investigation which are closely linked to the merits of the applicants ' complai nts. Thus, it decides to join this objection to the merits of the case and considers that the issue falls to be examined below.

II . THE COURT ' S ASSESSMENT OF THE EVIDENCE AND THE ESTABLISHMENT OF THE FACTS

A. The parties ' arguments

81 . The applicants maintained that it was beyond reasonable doubt that the men who had taken away Aslan and Mokhmad Mudayev had been State agents. In support of their complaint they referred to the following facts. The Government had confirmed to the Court that the local law-enforcement authorities had conducted a special operation on 29 January 2003, as a result of which Aslan and Mokhmad Mudayev had been taken to the Nadterechniy district department of the FSB along with ot her residents of Raduzhnoye. However, the applicants ' relatives had not been released on the following day, unlike the other detainees, and had never returned home. The Government ' s allegations that the two brothers had been released shortly after their apprehension were completely unsubstantiated and refuted by witness statements collected by the applicants and the official investigation. All the information disclosed by the Government about the criminal investigation supported the applicants ' assertion as to the involvement of State agents in the abduction of their relatives . Since Aslan and Mokhmad Mudayev had been missing for a very lengthy period, they could be presumed dead. That presumption was further supported by the circumstances in which they had been arrested, which should be recognised as life-threatening.

82 . The Government submitted that on 29 January 2003 the Nadterechniy district department of the FSB , under the command of it s head officer M.Kh., had conducted a special operation to identify the perpetrators of the abduction of two prosecution officials which had taken place prior to the events in question. As a result of the operation, Aslan and Mokhmad Mudayev had been taken to the Nadterechniy district department of the FSB for questioning . Their non-participation in the abduction of the officials had been established and the two brothers had been released. The Government further stated that the brothers might have absconded from the authorities . They further contended that the investigation into the incident was ongoing and that there was no evidence that State representatives might be responsible for the disappearance of the Mudayev brothers. The Government further argued that there was no convincing evidence that the applicants ' relatives were dead as their corpses had not been found. Referring to the witness statements obtained by the investigat ion , the Government pointed out that Mr E.A. and Mr S.Z. had stated that during their detention in the Nadterechniy district department of the FSB in February 2003 and after 26 April 2003 accordi ngly, they had not seen the Mudayev brothers either on the premises of the FSB office or during the transportation of the office ' s detainees in May 2003 after the partial destruction of the building as a result of the terrorist attack. The Government did not submit the se witness statements to the Court.

B . The Court ' s evaluation of the facts

83 . The Court observes that in its extensive jurisprudence it has developed a number of general principles relating to the establishment of facts in dispute, in particular when faced with allegations of disappearance under Article 2 of the Convention (for a summary of these, see Bazorkina v . Russia , no. 69481/01, §§ 103-109, 27 July 2006). T he Court also notes that the conduct of the parties when evidence is being obtained has to be taken into account (see Ireland v. the United Kingdom , § 161 , Series A no . 25 ).

84 . The Court notes that despite its requests for a copy of the investigation file into the abduction of Aslan and Mokhmad Mudayev , the Government produced only a few documents from the case file. The Government referred to Article 161 of the Code of Criminal Procedure. The Court observes that in previous cases it has already found this explanation insufficient to justify the withholding of key information requested by the Court (see Imakayeva v. Russia , no. 7615/02, § 123, ECHR 2006 - VIII (extracts)).

85 . In view of this and bearing in mind the principles referred to above, the Court finds that it can draw inferences from the Government ' s conduct in respect of the well-foundedness of the applicants ' allegations. T he Court will thus proceed to examine crucial elements in the present case that should be taken into account when deciding whether the applicants ' relatives can be presumed dead and whether their deaths can be attributed to the authorities.

86 . The applicants alleged that the persons who had taken Aslan and Mokhmad Mudayev away on 29 January 2003 and then killed them had been State agents. The Government did not dispute any of the main factual elements underlying the application . They acknowledged that the applicants ' relatives had been detained by State agents, but suggested that they had been released some time later.

87 . The Government submitted that the applicants ' relatives had been detained on 29 January 2003 by representatives of the local law ‑ enforcement agencies under the command of the head of the Nadterechniy district department of the FSB officer M. Kh. and taken to the FSB office for questioning and that they had been released shortly afterwards (see paragraph 25 above) . In support of their position the Government referred to the summary of the witness statement given by officer M.Kh. to the investigators (see paragraph 65 above) , which the Government did not submit to the Court. The Court would stress in this regard that the evaluation of the evidence and the establishment of the facts is a matter for the Court, and it is incumbent on it to decide on the evidentiary value of the documents submitted to it (see Çelikbilek v. Turkey , no. 27693/95, § 71 , 31 May 2005 ).

88 . T he Court notes that the applicants ' allegation is supported by the witness statements collected by the applicants and by the investigation . In particular, the Court notes that a number of witnesses pointed out that Aslan and Mokhmad Mudayev had not been released from detention in the FSB office unlike the other men who had been apprehended as a result of the special operation (see paragraphs 20, 21, 52 and 60 above) . It further observes that the Government ' s allegation that the applicants ' relatives were released after questioning was not substantiated by any documents. In their application t o the authorities the applicant s consistently maintained that Aslan and Mokhmad Mudayev had been arrested by servicemen under the command of officer M. Kh. and subsequently detained in the FSB office and requested the investigation to examine that possibility ( see paragraphs 31, 41, 45, 49 and 53 above) . The domestic investigation also accepted factual assumptions as presented by the applicants and questioned officer M. Kh. However, it does not appear that any serious steps were taken to verify his statement concerning the release of the applicants ' relatives.

89 . The Court observes that where applicants make out a prima facie case and the Court is prevented from reaching factual conclusions owing to a lack of relevant documents, it is for the Government to argue conclusively why the documents in question cannot serve to corroborate the allegations made by the applicants , or to provide a satisfactory and convincing explanation of how the events in question occurred. The burden of proof is thus shifted to the Government and if they fail in their arguments, issues will arise under Article 2 and/or Article 3 (see ToÄŸcu v. Turkey , no. 27601/95, § 95, 31 May 2005, and Akkum and Others v. Turkey , no. 21894/93, § 211, ECHR 2005 ‑ II).

90 . Taking into account the above elements, the Court is satisfied that the applicants have made a prima facie case that their relatives were apprehended by State servicemen. The Court observes that the Government submitted no evidence, such as records of detention and release, to corroborate their contention that the applicants ' relatives had been set free. As to the Government ' s contention that the records were destroyed as a result of the fire (see paragraph 26 above ), they failed to submit any evidence confirming that the impugned documents had been indeed destroyed as a result of it. No documents in the case file indeed refer to the destruction of the documents as a result of the incident . T he Court is struck by the fact that the source of this assertion is none other than the officer most closely implicated in the det ention of the Mudayev brothers . In such circumstances and taking into account the absence of any evidence to the contrary , the Court finds that Aslan and Mokhmad Mudayev remained under the control of the authorities after being apprehended during the special operation.

91 . The Court further notes that no documents relating to the applicants ' relatives ' apprehension and subsequent detention have been made available to it. There has been no reliable news of the Aslan and Mokhmad Mudayev since the date of the kidnapping. Their names have not been found in a ny official detention facility records. Finally, the Government have not submit ted any expla nation as to what happened to them after their arrest.

92 . Having regard to the previous cases conc erning disappearances in Chechnya which have come before i t (see, among others, Bazorkina , cited above; Imakayeva , cited above; Luluyev and Others v. Russia , no. 69480/01, ECHR 2006 ‑ ... (extracts); Baysayeva v. Russia , no. 74237/01, 5 April 2007; Ak hmadova and Sadulayeva , cited above; and Alikhadzhiyeva v. Russia , no. 68007/01, 5 July 2007 ), the Court finds that in the context of the conflict in the Republic, when a person is detained by servicemen without any subsequent acknowledgment of the detention, this can be regarded as life ‑ threatening. The absence of Aslan and Mokhmad Mudayev or of any news of them for many years supports this assumption. Furthermore, the Government have failed to provide any explanation as to the disappearance of the applicants ' relatives after their arrest , and the official investigation into their abduction, which has lasted for more than six years, has produced no tangible results.

93 . The Court further notes that, regrettably, it has been unable to benefit from the result s of the domestic investigation owing to the Government ' s failure to disclose most of the documents from the file (see paragraph 72 above). Nevertheless, it is clear that the investigation did not identify the perpetrators of the kidnapping.

94 . Accordingly, the Court finds that the evidence available permits it to establish that Aslan and Mokhmad Mudayev must be presumed dead following their unacknowledged detention by State servicemen.

III . ALLEGED VIOLATION OF ARTICLE 2 OF THE CONVENTION

95 . The applicants complained under Article 2 of the Convention that their relatives had been depriv ed of their lives by State agents and that the domestic authorities had failed to carry out an effective investigation of the matter. Article 2 reads:

“1. Everyone ' s right to life shall be protected by law. No one shall be deprived of his life intentionally save in the execution of a sentence of a court following his conviction of a crime for which this penalty is provided by law.

2. Deprivation of life shall not be regarded as inflicted in contravention of this article when it results from the use of force which is no more than absolutely necessary:

(a) in defence of any person from unlawful violence;

(b) in order to effect a lawful arrest or to prevent the escape of a person lawfully detained;

(c) in action lawfully taken for the purpose of quelling a riot or insurrection.”

A. The parties ' submissions

96 . The Government contended that the domestic investigation had obtained no evidence to the effect that Aslan and Mokhmad Mudayev were dead or that any servicemen of the federal law-enforcement agencies had been involved in their kidnapping or alleged killing. The Government claimed that the investigation into the kidnapping of the applicant s ' relative s met the Convention requirement of effectiveness, as all measures available under national law were being taken to identify those responsible.

97 . The applicants argued that Aslan and Mokhmad Mudayev had been detained by State servicemen and should be presumed dead in the absence of any reliable news of them f or years. The applicant s also argued that the investigation had not met the effectiveness and adequacy requirements laid down by the Court ' s case-law. The applicant s pointed out that by January 2005 the district prosecutor ' s office had not taken certain crucial investigative steps. The investigation into Aslan and Mokhmad Mudayev ' s kidnapping had been opened several months after the events and then had been suspended and resumed a number of times – thus delaying the taking of the most basic steps – and that the relatives had not been properly informed of the most important investigative measures. The fact that the investigation had been ongoing for such a long period of time without producing any known results was further proof of its ineffectiveness. They also invited the Court to draw conclusions from the Government ' s unjustified failure to submit the documents from the case file to them or to the Court.

B. The Court ' s assessment

1. Admissibility

98 . The Court considers, in the light of the parties ' submissions, that the complaint raises serious issues of fact and law under the Convention, the determination of which requires an examination of the merits. Further, the Court has already found that the Government ' s objection concerning the alleged non-exhaustion of domestic remedies should be joined to the merits of the complaint (see paragraph 80 above). The complaint under Article 2 of the Convention must therefore be declared admissible.

2. Merits

(a) The alleged violation of t he right to life of Aslan and Mokhmad Mudayev

99 . The Court h as already found that the applicants ' relatives must be presumed dead following unacknowledged detention by State servicemen . In the absence of any justification put forward by the Government , the Court finds that the ir deaths can be attributed to the State and that there has been a violation of Article 2 in respect of Aslan and Mokhmad Mudayev .

(b) The alleged inadequacy of the investigation of the kidnapping

100 . The Court has on many occasions stated that the obligation to protect the right to life under Article 2 of the Convention also requires by implication that there should be some form of effective official investigation when individuals have been killed as a result of the use of force. It has developed a number of guiding principles to be followed for an investigation to comply with the Convention ' s requirements (for a summary of these principles see Bazorkina , cited above, §§ 117-119).

101 . In the present case, the kidnapping of Aslan and Mokhmad Mudayev was investigated. The Court must assess whether that investigation met the requirements of Article 2 of the Convention.

102 . The Court notes at the outset that most of the documents from the investigation file were not disclosed by the Government. It therefore has to assess the effectiveness of the investigation on the basis of the few documents submitted by the parties and the information about its progre ss presented by the Government.

103 . The Court notes that the authorities were made aware of the crime by the applicants ' written submission on 22 September 2003 . The investigation in case no. 42172 was instituted on 29 Se ptember 2003 . Taking into account that the Government failed to furnish the Court with any information as to the dates of the investigative measures taken by the prosecutor ' s office, it is nonetheless clear that after the opening of the criminal case the investigators did not take even the most basic steps . For instance , the Court notes that, as can be seen from the decision of the district court of 30 December 2004, by that date the investigators had not questioned any of the persons involved in the arrest of the Mudayev brothers even though “ ... i n the course of the preliminary investigation it had been unequivocally established by whom and when the Mudayev brothers had been arrested and where they had been detained ... ” (see paragraph 44 above). It is obvious that if they were to produce any meaningful results such investigative measures should have been taken immediately after the investigation obtained the relevant information. Such delays, for which there has been no explanation in the instant case, not only demonstrate the authorities ' failure to act of their own motion but also constitute a breach of the obligation to exercise exemplary diligence and promptness in dealing with such a serious matter (see Öneryıldız v. Turkey [GC], no. 48939/99, § 94, ECHR 2004 ‑ XII ). Further, it does not appear that the investigation tried to identify and question any of the servicemen who had worked in the Nadterechniy district department of the FSB, other than officer M.Kh., in order to establish whether Aslan and Mokhmad Mudayev had been detained there after 29 January 2003 , or that the investigators tried to identify and question the more than twenty other residents of Raduzhnoye who had been arrested in the course of the same special operation.

104 . The Court also notes that even though the applicants were granted victim status in the criminal case concerning the abduction of their relatives , they were only informed of the suspension and resumption of the proceedings, and not of any other significant developments. Accordingly, the investigators failed to ensure that the investigation received the required level of public scrutiny, and to safeguard the interests of the next of kin in the proceedings.

105 . Finally, the Court notes that the investigation was adjourned and resumed on numerous occasions and that there were lengthy periods of inactivity on the part of the prosecutor ' s office when the proceedings were suspended . The district court criticised the deficiencies in the proceedings and ordered remedial measures (see paragraph 44 above) . It appears that its instructions were not complied with.

106 . The Government argued that the applicant s could have sought further judicial review of the decisions of the investigating authorities in the context of the exhaustion of domestic remedies. The Court observ es that the applicant s did, in fact, make use of that remedy, which eventually led to the resumption of the investigation. Nevertheless, the effectiveness of the investigation had already been undermined in its early stages by the authorities ' failure to take essential investigative measures. Moreover, the district court ' s instructions to the prosecutor ' s office to investigate the crime effectively did not bring any tangible results fo r the applicant s . The investigation was repeatedly suspended and resumed, but it appears that no significant investigative measures were taken to identify those responsible for the kidnapping. In such circumstances, the Cou rt considers that the applicant s could not be required to challenge in court every single decision of the district prosecutor ' s office. Accordingly, the Cou rt finds that the remedy cited by the Government was ineffective in the circumstances and dismisses their preliminary objection as regards the applicants ' failure to exhaust domestic remedies within the context of the criminal investigation.

107 . In the light of the foregoing, the Court holds that the authorities failed to carry out an effective criminal investigation into the circumstances surrounding the disappearance of Aslan and Mokhmad Mudayev , in breach of Article 2 in its procedural aspect.

I V. ALLEGED VIOLATION OF ARTICLE 3 OF THE CONVENTION

108 . The applicants relied on Article 3 of the Convention, submitting that after their arrest Aslan and Mokhmad Mudayev had been subjected to inhuman and degrading treatment and that the State had fail ed to investigate the applicants ' allegations about it in breach of Article 3 of t he Convention. Article 3 reads:

“ No one shall be subjected to torture or to inhuman or degrading treatment or punishment. ”

A. The parties ' submissions

109 . The Government disagreed with these allegations and argued that the investigation had not established that Aslan and Mokhmad Mudayev had been subjected to inhuman or degrading treatment prohibited by Article 3 of the Convention.

110 . The applicants maintained their submissions .

B. The Court ' s assessment

1. Admissibility

Ill-treatment of the applicants ' relatives

111 . The Court reiterates that allegations of ill-treatment must be supported by appropriate evidence. To assess this evidence, the Court adopts the standard of proof “ beyond reasonable doubt ” but adds that such proof may follow from the coexistence of sufficiently strong, clear and concordant inferences or of similar unrebutted presumptions of fact (see Ireland v. the United Kingdom , cited above, § 161 in fine ).

112 . The Court has already found that Aslan and Mokhmad Mudayev were detained on 29 January 2003 by federal forces and that no reliable news of them has been received since. It has also found that, in view of all the known circumstances, they can be presumed dead and that the responsibility for their death lies with the State authorities (see paragraph 99 above). However, the questions of the exact way in which they died and whether they were subjected to ill-treatment while in detention have not been elucidated. The Court considers that the applicants ' reference to the statement of Mr Aslan A. (see paragraph 21 above) does not enable it to find beyond all reasonable doubt that Aslan and Mokhmad Mudayev were ill-treated in detention. It thus finds that this part of the complaint has not been substantiated.

113 . It follows that this part of the application is manifestly ill-founded and should be rejected in accordance with Article 35 §§ 3 and 4 of the Convention.

2. Merits

Alleged ineffectiveness of the investigation of the ill-treatment

114 . The Court reiterates that “where an individual makes a credible assertion that he has suffered treatment infringing Article 3 at the hands of the police or other similar agents of the State, that provision, read in conjunction with the State ' s general duty under Article 1 of the Convention to secure to everyone within their jurisdiction the rights and freedoms defined in ... [the] Convention, requires by implication that there should be an effective official investigation” (see Labita v. Italy [GC], no. 26772/95, § 131, ECHR 2000 ‑ IV ).

115 . The Court notes that the applicants raised in detail their complaints about the ill ‑ treatment of Aslan and Mokhmad Mudayev with the investigating authorities (see paragraph 31 above) . However, it does not appear that their complaints were properly examined by the prosecutor ' s office .

116 . For the reasons stated above in paragraphs 103 – 107 in relation to the procedural obligation under Article 2 of the Convention, the Court concludes that the Government has failed to conduct an effective investigation into the ill-treatment of Aslan and Mokhmad Mudayev.

117 . Accordingly, there has been a violation of Article 3 in this respect.

V . ALLEGED VIOLATION OF ARTICLE 5 OF THE CONVENTION

118 . The applicants stated that Aslan and Mokhmad Mudayev had been detained in violation of the guarantees contained in Article 5 of the Convention. Article 5 reads, in so far as relevant:

“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: ...

(c) the lawful arrest or detention of a person effected for the purpose of bringing him before the competent legal authority on reasonable suspicion of having committed an offence or when it is reasonably considered necessary to prevent his committing an offence or fleeing after having done so;

...

2. Everyone who is arrested shall be informed promptly, in a language which he understands, of the reasons for his arrest and of any charge against him.

3. Everyone arrested or detained in accordance with the provisions of paragraph 1 (c) of this Article shall be brought promptly before a judge or other officer authorised by law to exercise judicial power and shall be entitled to trial within a reasonable time or to release pending trial. Release may be conditioned by guarantees to appear for trial.

4. Everyone who is deprived of his liberty by arrest or detention shall be entitled to take proceedings by which the lawfulness of his detention shall be decided speedily by a court and his release ordered if the detention is not lawful.

5. Everyone who has been the victim of arrest or detention in contravention of the provisions of this Article shall have an enforceable right to compensation.”

A. The parties ' submissions

119 . T he Government asserted that no evidence had been obtained by the investigators to confirm that Aslan and Mokhmad Mudayev had been deprived of their liberty . The brothers had been brought to the Nadterechniy district department of the FSB for questioning and had been released shortly afterwards. The applicants ' relatives were not listed among the persons kept in detention centres and none of the local law-enforcement agencies had information about their detention.

120 . The applicant s reiterated the complaint.

B. The Court ' s assessment

1. Admissibility

121 . The Court notes that this complaint is not manifestly ill-founded within the meaning of Article 35 § 3 of the Convention. It further notes that the complaint is not inadmissible on any other grounds and must therefore be declared admissible .

2. Merits

122 . The Court has previously noted the fundamental importance of the guarantees contained in Article 5 to secure the right of individuals in a democracy to be free from arbitrary detention. It has also stated that unacknowledged detention is a complete negation of these guarantees and discloses a very grave violation of Article 5 (see Çiçek v. Turkey , no. 25704/94, § 164, 27 February 2001, and Luluyev , cited above, § 122).

123 . The Court has found that Aslan and Mokhmad Mudayev were apprehended by State servicemen on 29 January 2003 and have not been seen since. Their detention was not acknowledged, was not logged in any custody records and there exists no official trace of their subsequent whereabouts or fate (see paragraph 90 above) . In accordance with the Court ' s practice, this fact in itself must be considered a most serious failing, since it enables those responsible for an act of deprivation of liberty to conceal their involvement in a crime, to cover their tracks and to escape accountability for the fate of a detainee. Furthermore, the absence of detention records, noting such matters as the date, time and location of detention and the name of the detainee as well as the reasons for the detention and the name of the person effecting it, must be seen as incompatible with the very purpose of Article 5 of the Convention (see Orhan , cited above, § 371).

124 . The Court further considers that the authorities should have been more alert to the need for a thorough and prompt investigation of the applicants ' complaints that their relatives had been detained and taken away in life-threatening circumstances. However, the Court ' s findings above in relation to Article 2 and, in particular, the conduct of the investigation leave no doubt that the authorities failed to take prompt and effective measures to safeguard them against the risk of disappearance.

125 . In view of the foregoing, the Court finds that Aslan and Mokhmad Mudayev were held in unacknowledged detention without any of the safeguards contained in Article 5. This constitutes a particularly grave violation of the right to liberty and security enshrined in Article 5 of the Convention.

VI. ALLEGED VIOLATION OF ARTICLE 18 IN CONJUNCTION WITH ARTICLE 5 § 1 (c) OF THE CONVENTION

126 . The applicants further alleged that the detention of their relatives was carried out for a purpose other than those envisaged by Article 5 § 1 (c), contrary to Article 18 of the Convention. Article 18 reads:

“ The restrictions permitted under this Convention to the said rights and freedoms shall not be applied for any purpose other than those for which they have been prescribed. ”

128 . The Court has already found in paragraphs 123-125 above that the applicants ' relatives were deprived of their liberty without any of the safeguards contained in Article 5 , and not “for the purpose of bringing [a person] before the competent legal authority on reasonable suspicion of having committed an offence” as stipulated in Article 5 § 1 (c). In these circumstances, since that issue has already been addressed by the Court, there is no need to examine these facts again under Article 18 in conjunction with Article 5 of the Convention.

VI I . ALLEGED VIOLATION OF ARTICLE 13 OF THE CONVENTION

129 . The applicants complained that they had been deprived of effective remedies in respect of the aforementioned violations, contrary to Article 13 of the Convention, which provides:

“Everyone whose rights and freedoms as set forth in [the] Convention are violated shall have an effective remedy before a national authority notwithstanding that the violation has been committed by persons acting in an official capacity.”

A. The parties ' submissions

130 . The Government contended that the applicants had had effective remedies at their disposal as required by Article 13 of the Convention and that the authorities had not prevented them from using them. The applicants had had an opportunity to challenge the acts or omissions of the investigating authorities in court and had availed themselves of it . They added that participants in criminal proceedings could also claim damages in civil proceedings. In sum, the Government submitted that there had been no violation of Article 13.

131 . The applicants reiterated the complaint.

B. The Court ' s assessment

1. Admissibility

132 . The Court notes that this complaint is not manifestly ill-founded within the meaning of Article 35 § 3 of the Convention. It further notes that it is not inadmissible on any other grounds. It must therefore be declared admissible.

2. Merits

133 . The Court reiterates that in circumstances where, as here, a criminal investigation into a disappearance has been ineffective (see paragraph 107 above) and the effectiveness of any other remedy that might have existed, including civil remedies , as suggested by the Government in the present case , has consequently been undermined the State has failed in its obligation under Article 13 of the Convention (see Khashiyev and Akayeva , cited above, § 183) .

134 . Consequently, there has been a violation of Article 13 in conjunction with Article 2 the Convention.

135 . As regards the ap plicants ' reference to Article s 3 and 5 of the Convention, the Court considers that, in the circumstances, no separate issues arise in respect of Article 13 in conjunction with Article s 3 and 5 of the Convention (see Kukayev v. Russia , no. 29361/02, § 119, 15 November 2007, and Aziyevy v. Russia , no. 77626/01, § 118, 20 March 2008).

VII I . APPLICATION OF ARTICLE 41 OF THE CONVENTION

136 . 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. Pecuniary damage

137 . The first applicant, as the father of Aslan and Mokhmad Mudayev , claimed damages in respect of loss of earnings by his sons after their arrests and subsequent disappearances . Referring to the method of calculation used in the case of Isayeva v. Russia ( no. 57950/00, § § 232-236 , 24 February 2005 ), he claimed a total of 21,600 euros (EUR) unde r this heading.

138 . The Government regarded these claims as unsubstantiated . They also pointed to the existence of domestic statutory machinery for the provision of a pension for the loss of a family breadwinner.

139 . The Court reiterates that there must be a clear causal connection between the damage claimed by an applicant and the violation of the Convention at issue , and that this may, in an appropriate case, include compensation in respect of loss of earnings. The Court further finds that loss of earnings also applies to elderly parents and that it is reasonable to assume that Aslan and Mokhmad Mudayev would eventually have had some earnings from which the first applicant would have benefited (see, among other authorities, Imakayeva , cited above, § 213) . Having regard to its above conclusions, it finds that there is a direct causal link between the violation of Article 2 in respect of the first applicant ' s sons and the loss by the first applicant of the financial support which they could have provided. Having regard to the applicants ' submissions and the fact that Aslan and Mokhmad Mudayev were not employed at the time of their apprehension, the Court awards EUR 20,000 to the first applicant in respect of pecuniary damage, plus any tax that may be chargeable on that amount.

B. Non-pecuniary damage

140 . The first applicant, as the father of the disappeared Aslan and Mokhmad Mudayev , claimed EUR 200,000 in respect of non-pecuniary damage for the suffering he had endured as a result of the loss of his family member s , the indifference shown by the authorities towards him and the failure to provide any information about the fate of his sons . The second applicant , as the aunt of the disappeared men, claimed 50,000 EUR under this head.

141 . The Government found the amounts claimed exaggerated.

142 . The Court has found a violation of Articles 2, 3, 5 and 13 of the Convention on account of the unacknowledged detention and disappearance of the applicants ' relatives . The Court thus accepts that the applicants have suffered non-pecuniary damage which cannot be compensated for solely by the findings of violations. It awards 100 ,000 EUR to the first applicant and 2 0 , 000 EUR to the second applicant plus any tax that may be chargeable on these amounts.

C. Costs and expenses

143 . The applicants were represented by lawyers of the Centre of Assistance t o International Protection , Ms K. Moskalenko and Ms S . Davydova . The applicants submitted that t he aggregate claim in respect of costs and expenses related to the ir legal representation amounted to EUR 4,500 .

144 . T he Government indicated that the applicants had not shown that the expenses claimed for legal representation had actually been incurred.

145 . The Court has to establish first whether the costs and expenses indicated by the applicant s ' representatives were actually incurred and, second, whether they were necessary (see McCann and Others, cited above, § 220).

146 . Having regard to the details of the information in its possession, the Court is satisfied that these rates are reasonable and reflect the expenses actually incurred by the applicants ' representatives.

147 . As to whether the costs and expenses were necessary , t he Court notes that this case was rather complex and required a certain amount of research and preparation.

148 . Having regard to the details of the claims submitted by the applicants, the Court awards them the amount of EUR 4,000 less EUR 850 received by way of legal aid from the Council of Europe, together with any value-added tax that may be chargeable thereon .

D. Default interest

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