36As regards the first plea in law alleging infringement of Article 190 of the Treaty, it must be observed, as a preliminary point, that the Council cited, as its reason for rejecting the application for access to the documents which the applicants ask to have disclosed to the Højesteret and the parties to the case pending before that court, the fact that the documents are the opinions of the Legal Services and, as such, confidential. It declared that in accordance with ‘long-standing practice’ those views would not be released, on the ground that disclosure of the opinions of the Legal Service on issues being dealt with in the Council could be detrimental ‘to the public interest in the maintenance of legal certainty and the stability of Community law, and also to the public interest in the Council's being able to obtain independent legal advice’.
37The applicants submit that the statement of reasons is generic in nature, and consequently insufficient.
38In this regard, it must be borne in mind that it is settled case-law that the statement of reasons required by Article 190 of the Treaty must be appropriate to the nature of the measure in question. It must show clearly and unequivocally the reasoning of the institution which enacted the measure so as to inform the persons concerned of the justification for the measure adopted and to enable the Court to exercise its powers of review (see, most recently, Joined Cases C-9/95, C-23/95 and C-156/95 Belgium and Germany v Commission [1997] ECR I-645, paragraph 44, and Joined Cases C-71/95, C-155/95, C-271/95 Belgium and Germany v Commission [1997] ECR I-687, paragraph 53).
39In this case it is first to be noted, that in its decision the Council refuses access to the two documents in question not because of their specific content but because they are opinions from the Legal Services of the Community institutions. Given the tenor of the decision, and in particular the fact that the two documents concerned contain opinions on legal matters from services internal to the administration, it would appear that a reference in the statement of reasons to the specific effects of releasing documents having such a content, as requested by the applicants, is not absolutely necessary in this case, and hence the fact that the Council did not examine the content of each document is not, taken alone, prima facie such as to render the statement of reasons inadequate. That conclusion is confirmed by the case-law of the Court of First Instance holding that the statement of the reasons for a decision refusing access to documents must contain ‘by reference to categories of documents’ the specific reasons for which it considers that the documents detailed in the request fall under one of the exceptions precluding such disclosure (in particular the exceptions provided for in Article 4(1) of Decision 93/731 and the first paragraph of the provision entitled ‘Exceptions’ of the Code of Conduct) but that such a statement of reasons need not furnish, in respect of each document, the ‘imperative reasons’ justifying the application of the public interest exception, inasmuch as it might seem impossible to give the reasons justifying the need for confidentiality in respect of each individual document without disclosing the content of the document and, thereby, depriving the exception of its purpose (see WWF UK ν Commission, cited above, paragraphs 64 and 65).
40Secondly, it should be noted that, in the statement of reasons for the decision the Council refers to the public interest which could be harmed if the opinions of the Legal Service were divulged. According to the Council, that interest relates both to the ‘maintenance of legal certainty and the stability of Community law’ and to the ‘Council's being able to obtain independent legal advice’. It follows clearly from the terms of the decision that, as it explained in both its written and oral observations, the Council considers that disclosure of legal opinions, as documents containing merely technical advice, could give rise to doubt as to the legality of Community acts and thus be detrimental to ‘legal certainty’ and the ‘stability of the Community law’. Such disclosure could, accordingly, give rise to difficulties with regard to the consultative role of those services and lead to the impoverishment of an instrument important to the Council's activities.
41On the basis of those considerations, it must be held that the reasons given for the decision are sufficiently clear and consequently in no way prevented the applicants from challenging or the President of the Court from reviewing the legality of the contested decision.
42In the light of the foregoing considerations, the plea alleging infringement of Article 190 of the Treaty must be rejected.
43The applicants plead a breach of the Code of Conduct and of Decision 93/731, claiming, first, that, contrary to what can be concluded from the Decision, the fact that the documents which they ask to have disclosed contain legal opinions does not, taken alone, exclude the possibility that the public should have access to them, and, secondly, that there is no exception, either in the Code of Conduct or Decision 93/731, expressly concerning the public interests relied upon in the decision, namely ‘the maintenance of legal certainty and the stability of Community law’ and ‘the Council's being able to obtain independent legal advice’.
44In that connection, it is first necessary to establish the scope of the documents in question in order then to determine whether the Council's refusal to grant access to them is justified in the light of the provisions which the applicants allege have been infringed.
45The opinions of the Legal Services are clearly internal documents — which is not, in principle, sufficient to ensure confidential treatment — primarily intended to provide the institution called upon to adopt a measure with an opinion on legal issues. They are, in other words, merely working instruments.
46Moreover, were documents of that nature to be disclosed, the discussions and exchange of views within the institutions on the legality and scope of the legal measure to be adopted would be made public and hence, as it stated, the Council might lose all interest in requesting the Legal Services for written opinions. In other words, it appears, at least on an initial examination, that disclosure of those documents could give rise to uncertainty with regard to the legality of Community measures and have a negative effect on the functioning of the Community institutions. The stability of the Community legal order and the proper functioning of the institutions, which are matters of public interest for which it is unquestionably necessary to have due regard, would suffer as a result.
47Consequently, given the special nature of the two documents in question, it prima fade appears that the grounds put forward by the defendant institution, namely, the requirement of ensuring ‘maintenance of legal certainty and stability of Community law’ and also of ensuring that ‘the Council [is] able to obtain independent legal advice’ must be regarded as legitimate, with regard to both the letter and the spirit of the provisions relied upon by the applicants.
48More specifically, on the question whether the protection of those interests is provided for in the Code of Conduct and in Decision 93/731, it should be noted that they state that ‘[a]ccess to a Council document shall not be granted where its disclosure could undermine... the protection of the public interest (public security, international relations, monetary stability, court proceedings, inspections and investigations)...’ (Article 4(1) of Decision 93/731 and the first paragraph of the provision entitled ‘Exceptions’ of the Code of Conduct). The formulation of the provision shows that although, on the one hand, it sets out in the first indent, in brackets, five categories of interests entitled to absolute protection, on the other hand it refers, at the beginning of that indent, to the general concept of ‘the public interest’. It is clear from the tenor of the provision that it is the protection of the public interest in general which may justify refusal to grant access to documents, and accordingly it would not be right to limit, contrary to the actual wording of that provision, the scope of the concept of the public interest by reducing it to the five cases set out in brackets.
49The applicants claim that, according to the case-law of the Court of First Instance, the list of exceptions to the general right of access to documents must be construed strictly (see WWF UK v Commission, cited above, paragraph 56). However, that judgment cannot cast doubt on the reading of Article 4(1) of Decision 93/731 and the first paragraph of the provision entitled ‘Exceptions’ of the Code of Conduct as set out above, which is based on a literal interpretation of those provisions. The latter are characterised, first, by an express reference to the general requirement that the public interest should be protected and enumerate, in brackets certain specific cases where it applies, while clearly and unequivocally attaching secondary importance to those cases.
50The applicants maintain, furthermore, that in any case the opinions which they ask to have disclosed to the Højesteret and the parties concerned are now only of historic interest and consequently may no longer be regarded as confidential. In that connection, it must be pointed out that, given the special nature of opinions of the Legal Services, it would not appear that those documents are bound, over the years, to lose their confidential character. Their disclosure could still be detrimental to the public interest in the stability of the Community legal order and the proper functioning of the Community institutions, inasmuch as time is not likely to alter the reasons, mentioned above, justifying such an exception to the right of access. Moreover, there is nothing in the file in support of the applicants' argument that would enable it to be established, from that point of view, that there was no justification for confidentiality in respect of the documents in question.
51Lastly, the applicants claim that there is discrimination, in this case, between the confidentiality accorded to the legal opinions of services internal to the Community institutions and that accorded to legal opinions issued within entities of a different nature which have their own organisation and services, including a legal service. As far as the institutions are concerned, internal opinions are regarded as confidential, whereas, according to the case-law of the Court, only written communications with an independent lawyer ‘not bound to the client by a relationship of employment’ and which concern the client's defence enjoy such confidentiality (AM&S ν Commission, cited above).
52The President of the Court finds that that case-law may not be relied upon in the present case. The judgment in AM&S did not concern public access to the documents of private individuals but rather disclosure to the Commission of the documents of an undertaking which was the subject of an investigation under the Community competition rules. In other words, it concerned the interpretation of rules of administrative procedure in competition cases, specifically the Commission's powers of investigation. Moreover, the interests underlying the confidentiality of written communications between lawyer and client in the course of the administrative procedure before the Commission are quite different from those which justify refusal to grant public access to legal opinions emanating from the services of the institutions. That same judgment makes clear that, in protecting written communications between lawyer and client ‘care is taken to ensure that the rights of the defence [of the undertaking] may be exercised to the full’ and that protection extends only to an independent lawyer in so far as his role is conceived ‘as collaborating in the administration of justice by the courts and as being required to provide, in full independence, and in the overriding interests of that cause, such legal assistance as the client needs’(AM&S ν Commission, cited above, paragraphs 23 and 24). In this case, however, what is involved is the protection of the public interest in the stability of Community law and the proper functioning of the institutions. That requirement entails, for the reasons already set out, that opinions of the Legal Services must remain confidential. Accordingly that complaint by the applicants also appears to be lacking in any foundation.
53It follows from the foregoing that the second plea, alleging a breach of Decision 93/731 and the Code of Conduct, must be rejected.
