(EC Treaty, Art. 190)

1. Article 118a of the Treaty is the appropriate legal basis for the adoption by the Community of measures whose principal aim is the protection of the health and safety of workers, notwithstanding the ancillary effects which such measures may have on the establishment and functioning of the internal market. Since its aim is to ensure that protection, Article 118a constitutes a more specific rule than Articles 100 and 100a, the existence of which does not have the effect of restricting its scope, and must be widely interpreted as regards the scope it gives for Community legislative action regarding the health and safety of workers. Such action may comprise measures which are of general application, not merely measures specific to certain categories of workers, and which have to be in the nature of minimum requirements only in the sense that Member States remain at liberty to adopt more protective measures.

It is for that reason that, in terms of both its aim and its content, Directive 93/104 concerning certain aspects of the organization of working time could, save for the provisions in the second paragraph of Article 5 giving priority to Sunday as the weekly rest day which must therefore be annulled, be adopted on the basis of Article 118a.

2. As part of the system of Community competence, the choice of the legal basis for a measure must be based on objective factors which are amenable to judicial review. Those factors include, in particular, the aim and content of the measure.

A mere Council practice cannot derogate from the rules laid down in the Treaty, and cannot therefore create a precedent binding on the Community institutions where, prior to the adoption of a measure, they have to determine the correct legal basis for it.

3. Article 235 of the Treaty may be used as the legal basis for a measure only where no other Treaty provision confers on the Community institutions the necessary power to adopt it.

4. The adoption by the Council of Directive 93/104 concerning certain aspects of the organization of working time did not constitute an infringement of the principle of proportionality.

The limited power of review which the Community judicature has over the Council' s exercise of its wide discretion in the area of the protection of workers' health and safety, where social policy choices and complex assessments are involved, has not revealed either that the measures forming the subject-matter of the directive, save for that contained in the second paragraph of Article 5, were unsuited to achieving the aim pursued, namely workers' health and safety, or that those measures, which have a degree of flexibility, went beyond what was necessary to attain their objective.

5. An act of a Community institution is vitiated by a misuse of powers if it has been adopted with the exclusive or main purpose of achieving ends other than those stated or evading a procedure specifically prescribed by the Treaty for dealing with the circumstances of the case.

That is not the case with Council Directive 93/104 concerning certain aspects of the organization of working time, since it has not been established that it was adopted with the exclusive or main purpose of achieving an end other than the protection of the health and safety of workers envisaged by Article 118a of the Treaty which constitutes its legal basis.

6. Whilst the statement of reasons required by Article 190 of the Treaty must show clearly and unequivocally the reasoning of the Community authority which adopted the contested measure so as to enable the persons concerned to ascertain the reasons for it and to enable the Court to exercise judicial review, the authority is not required to go into every relevant point of fact and law.

Where a contested measure clearly discloses the essential objective pursued by the institution, it would be pointless to require a specific statement of reasons for each of the technical choices made by it.

gives the following

Judgment

1 By application lodged at the Court Registry on 8 March 1994, the United Kingdom of Great Britain and Northern Ireland brought an action under Article 173 of the EC Treaty for the annulment of Council Directive 93/104/EC of 23 November 1993 concerning certain aspects of the organization of working time (OJ 1993 L 307, p. 18, hereinafter "the directive") and, in the alternative, of Article 4, the first and second sentences of Article 5, Article 6(2) and Article 7 of the directive.

2 The directive was adopted on the basis of Article 118a of the Treaty, which provides as follows:

"1. Member States shall pay particular attention to encouraging improvements, especially in the working environment, as regards the health and safety of workers, and shall set as their objective the harmonization of conditions in this area, while maintaining the improvements made.

2. In order to help achieve the objective laid down in the first paragraph, the Council, acting in accordance with the procedure referred to in Article 189c and after consulting the Economic and Social Committee, shall adopt by means of directives minimum requirements for gradual implementation, having regard to the conditions and technical rules obtaining in each of the Member States.

Such directives shall avoid imposing administrative, financial and legal constraints in a way which would hold back the creation and development of small and medium-sized undertakings.

3. The provisions adopted pursuant to this article shall not prevent any Member State from maintaining or introducing more stringent measures for the protection of working conditions compatible with this Treaty."

3 The directive, in accordance with Article 1 thereof, lays down minimum health and safety requirements for the organization of working time, and applies to all sectors of activity, both public and private, within the meaning of Article 2 of Council Directive 89/391/EEC of 12 June 1989 on the introduction of measures to encourage improvements in the safety and health of workers at work (OJ 1989 L 183, p. 1), with the exception of air, rail, road, sea, inland waterway and lake transport, sea fishing, other work at sea and the activities of doctors in training.

4 Section II of the directive regulates minimum periods of daily rest, weekly rest and annual leave, as well as rest breaks and maximum weekly working time. Member States are thus obliged to take the measures necessary to ensure that every worker is entitled to a minimum daily rest period of eleven consecutive hours per twenty-four hour period (Article 3), to a rest break where the working day is longer than six hours, the details of such break to be determined by the two sides of industry or by national legislation (Article 4), to a minimum uninterrupted rest period of twenty-four hours in each seven-day period, plus the eleven hours daily rest referred to in Article 3 (Article 5, first sentence), such period in principle to include Sunday (Article 5, second sentence), and, finally, to four weeks' paid annual leave (Article 7).

5 Furthermore, Article 6 requires Member States to take the measures necessary to ensure that, in keeping with the need to protect the health and safety of workers, the period of weekly working time is determined by the two sides of industry or by national legislation, provided that the average working time for each seven-day period, including overtime, does not exceed forty-eight hours.

6 Section III of the directive contains various requirements concerning night work, shift work and patterns of work. Member States are accordingly obliged to take the measures necessary to ensure that normal hours of work for night workers do not exceed an average of eight hours in any twenty-four hour period, and that, where the work involves special hazards or heavy physical or mental strain, they do not work more than eight hours in any twenty-four hour period during which they perform night work (Article 8). Night workers must also be entitled to a free health assessment before their assignment and thereafter at regular intervals, and, where they suffer from health problems linked to night work, must be transferred whenever possible to day work to which they are suited (Article 9). Article 10 authorizes Member States to make the work of certain categories of night workers subject to certain guarantees, in the case of workers who incur risks to their health or safety linked to night-time working, and Article 12 obliges Member States, in particular, to take the measures necessary to ensure that night workers and shift workers have health and safety protection appropriate to the nature of their work.

7 Member States are also to take measures to ensure that an employer who regularly uses night workers brings that information to the attention of the competent authorities if they so request (Article 11). Finally, where work is organized according to a certain pattern, employers are to take account of the general principle of adapting work to the worker, with a view, in particular, to alleviating monotonous work and work at a predetermined work-rate, depending on the type of activity, and also of health and safety requirements (Article 13).

8 Section IV of the directive contains miscellaneous provisions. Article 14 provides that the directive is not to apply where there are other more specific Community provisions concerning certain occupations or occupational activities. Article 15 provides that Member States may apply, or permit the application of, provisions which are more favourable than those contained in the directive. Article 16 empowers Member States to lay down reference periods for the application of the provisions on the weekly rest period, maximum weekly working time and the length of night work. Finally, Article 17 lists the derogations which may be made from certain provisions, while Article 18 lays down various periods for transposition of the directive into national law.

9 In support of its action, the applicant relies on four pleas, alleging, respectively, that the legal base of the directive is defective, breach of the principle of proportionality, misuse of powers, and infringement of essential procedural requirements.

The plea that the legal base of the directive is defective

10 The applicant contends that the directive should have been adopted on the basis of Article 100 of the EC Treaty, or Article 235 of the Treaty, which require unanimity within the Council.

The scope of Article 118a

11 The applicant observes in the first place that, because Article 118a of the Treaty must be regarded as an exception to Article 100 ° which, pursuant to Article 100a(2), is the article that covers provisions "relating to the rights and interests of employed persons" ° it must be strictly interpreted.

13 Second, referring to the actual wording of Article 118a, the applicant argues first that that provision permits the adoption only of directives which have a genuine and objective link to the "health and safety" of workers. That does not apply to measures concerning, in particular, weekly working time, paid annual leave and rest periods, whose connection with the health and safety of workers is too tenuous. That interpretation is borne out by the expression "working environment" used in Article 118a, which implies that directives based on that provision must be concerned only with physical conditions and risks at the workplace.

16 The applicant further argues that under Article 118a(2) the Council may adopt only "minimum requirements" for gradual implementation, having regard to the conditions and technical rules obtaining in the Member States. That provision therefore empowers the Council to adopt harmonization measures only at a level acceptable to all Member States and constituting a minimum benchmark.

18 Third, the applicant argues that, in the light of previous directives based on Article 118a, that provision does not authorize the Council to adopt directives, such as that in dispute here, which deal with the question of health and safety in a generalized, unspecific and unscientific manner. Thus, Directive 89/391 established a risk assessment procedure designed to pinpoint specific areas in which action was required to safeguard the health and safety of workers. Similarly, the other directives based on Article 118a fall into two categories, namely "individual" directives within the meaning of Article 16 of Directive 89/391 (concerning, in particular, the provision of safety and health signs at work or the regulation of risks connected with exposure to carcinogens), and directives which, whilst not based on Directive 89/391, clearly focus upon a specific health or safety problem in a specific situation.

20 Furthermore, there is no support in the wording of Article 118a for the argument that Community action should be restricted to specific measures applicable to given groups of workers in particular situations, whilst measures for wider purposes should be adopted on the basis of Article 100 of the Treaty. Article 118a refers to "workers" generally and states that the objective which it pursues is to be achieved by the harmonization of "conditions" in general existing in the area of the health and safety of those workers.

21 In addition, the delimitation of the respective fields of application of Articles 100 and 100a, on the one hand, and Article 118a, on the other, rests not upon a distinction between the possibility of adopting general measures in the former case and particular measures in the latter, but upon the principal aim of the measure envisaged.

22 It follows that, where the principal aim of the measure in question is the protection of the health and safety of workers, Article 118a must be used, albeit such a measure may have ancillary effects on the establishment and functioning of the internal market (see, in particular, Parliament v Council, cited above, paragraph 32).

23 Finally, it is to be remembered that it is not the function of the Court to review the expediency of measures adopted by the legislature. The review exercised under Article 173 must be limited to the legality of the disputed measure.

24 It is in the light of those considerations that the Court must examine whether the directive was properly adopted on the basis of Article 118a of the Treaty.

The choice of legal basis for the directive

26 As regards the aim of the directive, the applicant argues that it represents a continuation of the Community' s earlier thinking and of a series of earlier initiatives at Community level concerned with the organization of working time in the interests of job creation and reduced unemployment. It is in reality a measure concerned with the overall improvement of the living and working conditions of employees and with their general protection, and is so broad in its scope and coverage as to be capable of classification as a social policy measure, for the adoption of which other legal bases exist.

27 It is to be noted in that respect that, according to the sixth recital in its preamble, the directive constitutes a practical contribution towards creating the social dimension of the internal market. However, it does not follow from the fact that the directive falls within the scope of Community social policy that it cannot properly be based on Article 118a, so long as it contributes to encouraging improvements as regards the health and safety of workers. Indeed, Article 118a forms part of Chapter 1, headed "Social Provisions", of Title VIII of the Treaty, which deals in particular with "Social Policy". This led the Court to conclude that that provision conferred on the Community internal legislative competence in the area of social policy (Opinion 2/91, cited above, paragraph 17).

28 Furthermore, as the Advocate General has demonstrated in points 85 to 90 of his Opinion, the organization of working time is not necessarily conceived as an instrument of employment policy. In this case, the fifth recital in the preamble to the directive states that the improvement of workers' safety, hygiene and health at work is an objective which should not be subordinated to "purely economic considerations". Were the organization of working time to be viewed as a means of combating unemployment, a number of economic factors would have to be taken into account, such as, for example, its impact on the productivity of undertakings and on workers' salaries.

29 The approach taken by the directive, viewing the organization of working time essentially in terms of the favourable impact it may have on the health and safety of workers, is apparent from several recitals in its preamble. Thus, for example, the eighth recital states that, in order to ensure the safety and health of Community workers, they must be granted minimum rest periods and adequate breaks and that it is also necessary in that context to place a maximum limit on weekly working hours. In addition, the eleventh recital states that "research has shown that ... long periods of night work can be detrimental to the health of workers and can endanger safety at the workplace", while the fifteenth recital states that specific working conditions may have detrimental effects on the safety and health of workers and that the organization of work according to a certain pattern must take account of the general principle of adapting work to the worker.

30 While, in the light of those considerations, it cannot be excluded that the directive may affect employment, that is clearly not its essential objective.

31 As regards the content of the directive, the applicant argues that the connection between the measures it lays down, on the one hand, and health and safety, on the other, is too tenuous for the directive to be based on Article 118a of the Treaty.

32 In that respect, it argues that no adequate scientific evidence exists to justify the imposition of a general requirement to provide for breaks where the working day is longer than six hours (Article 4), a general requirement to provide for a minimum uninterrupted weekly rest period of twenty-four hours in addition to the usual eleven hours' daily rest (Article 5, first sentence), a requirement that the minimum rest period must, in principle, include Sunday (Article 5, second sentence), a general requirement to ensure that the average working time for each seven-day period, including overtime, does not exceed forty-eight hours (Article 6(2)), and a general requirement that every worker is to have a minimum of four weeks' paid annual leave (Article 7).

33 The applicant points out in that connection that Directive 89/391 provides for employers to carry out assessments to evaluate specific risks to the health and safety of workers, taking into account the nature of the activities of the undertaking. The risk assessment procedure laid down by Directive 89/391 could not apply to the restrictions on working time contained in Section II of the contested directive (and is applicable only to a very limited extent in Section III), the provisions in question being quite simply mandatory and leaving no scope for such an assessment in order to determine whether they are to apply.

34 The applicant maintains, moreover, that unlike other provisions based on Article 118a of the Treaty, the contested measures were not referred to the Advisory Committee on Safety, Hygiene and Health Protection at Work for an opinion (on the role of such committees, it cites Case C-212/91 Angelopharm [1994] ECR I-171, paragraphs 31 and 32). Although consultation of that committee is not expressly provided for in cases such as this, the fact that the Council did not call on the Commission to undertake such consultation casts further doubt on the link between the directive and the health and safety of workers.

35 Finally, in the applicant' s view, contrary to the requirements of Article 118a(2), the provisions of the directive do not constitute "minimum requirements for gradual implementation, having regard to the conditions and technical rules obtaining in each of the Member States" and do not take account of their effects on "the creation and development of small and medium-sized undertakings".

36 In order to deal with those arguments, a distinction must be drawn between the second sentence of Article 5 of the directive and its other provisions.

37 As to the second sentence of Article 5, whilst the question whether to include Sunday in the weekly rest period is ultimately left to the assessment of Member States, having regard, in particular, to the diversity of cultural, ethnic and religious factors in those States (second sentence of Article 5, read in conjunction with the tenth recital), the fact remains that the Council has failed to explain why Sunday, as a weekly rest day, is more closely connected with the health and safety of workers than any other day of the week. In those circumstances, the applicant' s alternative claim must be upheld and the second sentence of Article 5, which is severable from the other provisions of the directive, must be annulled.

38 The other measures laid down by the directive, which refer to minimum rest periods, length of work, night work, shift work and the pattern of work, relate to the "working environment" and reflect concern for the protection of "the health and safety of workers". The scope of those terms has been explained in paragraph 15 of this judgment. Moreover, as the Belgian Government has pointed out, the evolution of social legislation at both national and international level confirms the existence of a link between measures relating to working time and the health and safety of workers.

40 Similarly, the applicant' s argument that the directive precludes any assessment of the risks involved for certain workers or for those working in a particular sector cannot be regarded as well founded. The Community legislature did take certain special situations into account, as is demonstrated by Article 1 of the directive, which excludes certain sectors or activities from its scope; by Article 14, which excludes occupations and occupational activities where more specific Community provisions apply; and by Article 17(1) and (2) which allow derogations from Articles 3, 4, 5, 6 and 8 in respect of certain groups of workers or certain sectors of activity (see points 114 to 117 of the Advocate General' s Opinion).

41 It is true that the Council did not consult the Advisory Committee on Safety, Hygiene and Health Protection at Work established by Council Decision 74/325/EEC of 27 June 1974 (OJ 1974 L 185, p. 15) with regard to the measures envisaged by the directive. However, under Article 2(1) of that decision, such consultation is intended only "[to assist] the Commission in the preparation and implementation of activities in the fields of safety, hygiene and health protection at work", and does not therefore constitute a condition precedent for action by the Council. In those circumstances, failure to consult that committee cannot be relied on to cast doubt on the link between the measures laid down by the directive and the protection of the health and safety of workers.

42 Furthermore, the provisions of the directive are "minimum requirements" within the meaning of Article 118a of the Treaty. Whilst ensuring a certain level of protection for workers, the directive authorizes Member States in Article 15 to apply, or facilitate the application of, measures which are more favourable to the protection of the health and safety of workers, thereby guaranteeing them a more stringent level of protection, in accordance with Article 118a(3). Similarly, Article 18(3) of the directive states that, whilst Member States may provide for different measures in the field of working time, subject to compliance with the minimum requirements it lays down, implementation of the directive does not constitute valid grounds for reducing the general level of protection afforded to workers.

43 The measures laid down by the directive are also, in accordance with Article 118a, "for gradual implementation, having regard to the conditions and technical rules obtaining in each of the Member States". In the first place, it is not in dispute that legislation in all the Member States includes measures on the organization of working time. Furthermore, Article 18 of the directive authorizes Member States, subject to certain conditions, not to apply, after the expiry of the time-limit for implementing the directive (23 November 1996), the provisions of Article 6 on weekly working time or, for a three-year transitional period, the provisions of Article 7 on paid annual leave, which may during that period be limited to three weeks.

45 Since it is clear from the above considerations that, in terms of its aim and content, the directive has as its principal objective the protection of the health and safety of workers by the imposition of minimum requirements for gradual implementation, neither Article 100 nor Article 100a could have constituted the appropriate legal basis for its adoption.

46 The applicant further maintains that the Community legislature neither fully considered nor adequately demonstrated whether there were transnational aspects which could not be satisfactorily regulated by national measures, whether such measures would conflict with the requirements of the EC Treaty or significantly damage the interests of Member States or, finally, whether action at Community level would provide clear benefits compared with action at national level. In its submission, Article 118a should be interpreted in the light of the principle of subsidiarity, which does not allow adoption of a directive in such wide and prescriptive terms as the contested directive, given that the extent and the nature of legislative regulation of working time vary very widely between Member States. The applicant explains in this context, however, that it does not rely upon infringement of the principle of subsidiarity as a separate plea.

49 It must therefore be held that the directive was properly adopted on the basis of Article 118a, save for the second sentence of Article 5, which must accordingly be annulled.

The plea of breach of the principle of proportionality

The plea of misuse of powers

68 According to the applicant, the directive encompasses a number of measures that have no objective connection with its purported aims, and must therefore be annulled in its entirety. Those measures overshadow the very small elements ° minimum daily rest periods, restrictions on maximum duration of night work ° where scientific evidence indicates that there may be some causal connection with health and safety. Those two elements, in respect of which limited and specific action might have been justifiable, have instead been addressed in an unspecific, generalized, and thus unlawful manner.

70 As is apparent from the Court' s examination of the plea of defective legal base, the Council could properly found the directive on Article 118a of the Treaty. The applicant has failed to establish that the directive was adopted with the exclusive or main purpose of achieving an end other than the protection of the health and safety of workers.

71 In those circumstances, the plea of misuse of powers must be rejected.

The plea of infringement of essential procedural requirements

72 The applicant' s primary submission is that the directive is inadequately reasoned. It does not clearly and unequivocally disclose the reasoning of the Community authority which adopted it, because it fails to demonstrate the causal connection relied on by the Community legislature between health and safety, on the one hand, and most of the measures it contains concerning working time (Articles 3, 4, 5, 6(2), 7 and 8), on the other. Nor, moreover, does the preamble to the directive explain why Community action was necessary.

73 In the alternative, the applicant submits that the directive is defectively reasoned, in that the legislature should have explained that many of its elements were concerned with the improvement of the living and working conditions of employees or with the social dimension of the internal market, rather than referring, as it did, to the health and safety of workers.

78 The argument that the Council should have included in the preamble to the directive specific references to scientific material justifying the adoption of the various measures which it contains must be rejected.

79 As stated in paragraph 39 of this judgment, Article 118a does not require scientific proof to be produced for every measure adopted on the basis of that provision. Moreover, the Court has held that, where a contested measure clearly discloses the essential objective pursued by the institution, it would be pointless to require a specific statement of reasons for each of the technical choices made by it (see Case C-122/94 Commission v Council, cited above, paragraph 29).

80 Nor can the argument to the effect that the preamble to the directive fails to explain the need for Community action be accepted as well founded.

81 As has been pointed out in paragraphs 75 to 77 of this judgment, the preamble to the directive shows that the Council considered it necessary, in order to ensure an improved level of health and safety protection of workers, to take action to harmonize the national legislation of the Member States on the organization of working time. As stated in paragraph 47, the pursuit of such an objective, laid down in Article 118a itself, through harmonization by means of minimum requirements, necessarily presupposes Community-wide action.

82 Finally, as regards the arguments concerning alleged errors of assessment in the preamble to the directive, it is sufficient to refer to the Court' s case-law to the effect that such questions relate not to the issue of infringement of essential procedural requirements but to the substance of the case (see, in particular, Joined Cases C-296/93 and C-307/93 France and Ireland v Commission [1996] ECR I-795, paragraph 76), and to recall that those questions have been examined in the context of the plea of defective legal base.

83 It follows that the plea of infringement of essential procedural requirements must also be rejected.

84 The application must accordingly be dismissed, save as regards the second sentence of Article 5 of the directive, which is to be annulled.

Costs

85 Under Article 69(2) of the Rules of Procedure, the unsuccessful party is to be ordered to pay the costs if they have been applied for in the successful party' s pleadings. Since the Council of the European Union has applied for costs, and the United Kingdom of Great Britain and Northern Ireland has been essentially unsuccessful, the latter must be ordered to pay the costs. Pursuant to the first sentence of Article 69(4) of the Rules of Procedure, the Kingdom of Belgium, the Kingdom of Spain and the Commission of the European Communities, which have intervened in the proceedings, are to bear their own costs.

On those grounds,

THE COURT

hereby:

1. Annuls the second sentence of Article 5 of Council Directive 93/104/EC of 23 November 1993 concerning certain aspects of the organization of working time;

2. Dismisses the remainder of the application;

3. Orders the United Kingdom of Great Britain and Northern Ireland to pay the costs;

4. Orders the Kingdom of Belgium, the Kingdom of Spain and the Commission of the European Communities to bear their own costs.
