The wording of the third sentence of Article 4(2) of the Environmental Information Directive
39. Contrary to the view expressed by Sweden and the Information Commissioner, the use of the term ‘interest’ in the singular does not preclude a cumulation of several interests. Admittedly, most of the language versions(17) in each case compare only the public interest served by disclosure with the interest served by the refusal, i.e. the term ‘the interest’ is used in the singular. However, ‘the interest’ served by one thing or another can, by its natural literal meaning, encompass various (different) interests which are indicative of one or other outcome.
40. Nor does emphasis on the particular case in which the balancing exercise is to be carried out proscribe cumulation. As argued by the United Kingdom, the more obvious interpretation is that the term ‘in the particular case’ means that it relates to the specific decision that is pending on the disclosure of information.(18)
41. Furthermore, the breakdown of interests meriting protection into different exceptions does not preclude their cumulation. As convincingly argued by the United Kingdom, these exceptions are not always clearly distinguishable from each other. Indeed, the interests meriting protection sometimes clearly overlap. This is immediately apparent in the case of the interests meriting protection under subparagraphs (d) to (g) of Article 4(2) of the Environmental Information Directive: the confidentiality of commercial or industrial information, intellectual property rights, personal data and the interests or protection of any person who supplied information on a voluntary basis.
42. Nor can Sweden ultimately succeed in its argument that the balancing exercise under the Environmental Information Directive should be conducted in exactly the same way as under Regulation No 1049/2001.
43. First, the manner in which the present question would be answered under Regulation No 1049/2001 has not yet been established at all. The Court of Justice has not yet examined whether a cumulation of interests is possible or even imperative in a balancing exercise under the regulation.(19)
44. Second, the text of the regulation with regard to the balancing exercise clearly differs from that of the Environmental Information Directive. Under Article 4(2) and (3) of the regulation(20) access to documents may be refused where certain protected interests are undermined ‘unless there is an overriding public interest in disclosure’. This balancing requirement is more restrictively worded than the third sentence of Article 4(2) of the Environmental Information Directive.
Restriction of possible exceptions
45. However, Sweden rightly argues that a cumulation of interests cannot create additional exceptions to the right to information.
46. Under the first sentence of recital 16 of the Environmental Information Directive the disclosure of environmental information may be refused only in specific and clearly defined cases. These cases are expressly set out in Article 4(1) and the first sentence of Article 4(2). These exceptions, by their very wording, are not illustrative but exhaustive.(21) This is confirmed by the restrictive interpretation required under the second sentence of Article 4(2).
47. Additional exceptions would also conflict with the Aarhus Convention, which in Article 4(3) and(4) similarly makes provision for certain expressly stated exceptions only.(22) That Convention, like all other international conventions concluded by the European Union, prevails over provisions of secondary Union legislation.(23) Because of that primacy, secondary Community legislation is to be interpreted as far as possible consistently with the Union’s obligations under international law,(24) which must also apply in the context of environmental information.(25)
48. The third sentence of Article 4(2) of the Environmental Information Directive must not therefore lead to additional exceptions that are not expressly listed in Article 4(1) and the first sentence of Article 4(2).
49. It would therefore be manifestly impossible to permit interests to be included in a balancing exercise under the third sentence of Article 4(2) of the Environmental Information Directive which, although they might militate against disclosure, are not recognised in Article 4 as a basis for exceptions to the right of access to environmental information, e.g. the cost of handling enquiries.
50. The Commission also correctly points out that the category of interests meriting protection is further restricted in the case of decisions on disclosure of information on emissions. Under the fourth sentence of Article 4(2) of the Environmental Information Directive – the so-called ‘emissions clause’ – most of the interests stated in Article 4(2) cannot justify refusal. Protection of the confidentiality of proceedings of public authorities (Article 4(2)(a)) or of commercial or industrial information (Article 4(2)(d)) is therefore precluded, for instance. Nor, therefore, can those interests be included in a balancing exercise on the disclosure of information on emissions.
51. Nor would it be possible to take into account recognised interests that are indeed affected but where it is impossible to establish in the context of an initial balancing exercise under the second sentence of Article 4(2) of the Environmental Information Directive that a disclosure of information would have adverse effects. Interests that are not undermined cannot have any weight in a balancing exercise. If therefore effects on those interests are established they must be of a negative kind if they are to be included in the balancing exercise.
52. The main issue, however, is whether additional exceptions are created by a cumulation of recognised adversely affected confidentiality interests during the balancing exercise.
53. Cumulation can unquestionably bring about an additional restriction of access to environmental information if several interests together justify a refusal of disclosure even though, when taken in isolation, they would be outweighed by the public interest served by disclosure. It would nevertheless still always be a question of restriction of access based on recognised interests.
54. I agree with the United Kingdom in considering that this additional restriction correctly applies the principle of proportionality.
55. The principle of proportionality is one of the general principles of EU law which the legislature must observe.(26) The acts of the bodies of the European Union must, therefore, not exceed the bounds of what is appropriate and necessary in order to achieve the objectives legitimately pursued by the legislation in question. When there is a choice between several appropriate measures, recourse must be had to the least onerous, and the disadvantages caused must not be disproportionate to the aims pursued.(27)
56. However, if the recognised interests militating against disclosure were together to clearly outweigh the public interest served by disclosure, the disadvantages caused by the disclosure of environmental information would no longer be proportionate to the aims pursued.
57. Whilst Sweden and the Information Commissioner are relying on the requirement that exceptions be afforded a restrictive interpretation, not even that principle demands the disclosure of environmental information which leads to disproportionate disadvantages. It should instead be observed when interpreting the exceptions, weighing up the interests and in the course of the balancing exercise itself. One cannot, in particular, blindly set two disadvantages against one advantage; the interests concerned must be assigned a weight that reflects their significance before the balancing exercise begins.
58. The Information Commissioner does indeed fear that the balancing of cumulative interests would be difficult to achieve in practice; however, these difficulties lie less in cumulation itself than in the nature of the balancing exercise between the interests served by disclosure and the interests served by the withholding of information. These interests are generally only comparable with difficulty, so that it is also difficult to weigh them against each other. This balancing exercise is made easier, however, if one applies the requirement of a restrictive interpretation of exceptions during the balancing exercise such that, in the event of doubt, the issue is decided in favour of transparency.
59. Furthermore, the balancing exercise itself can require cumulation in the context of individual exceptions, that is to say – as correctly argued by the United Kingdom – on the side of the public interest served by disclosure.(28) Recital 1 in the preamble to the Environmental Information Directive refers to three different interests: first, a greater awareness of environmental matters; second, a free exchange of views and more effective participation by the public in environmental decision-making; and third, a better environment.
60. Consequently, the answer to the reference for a preliminary ruling should be that where a public authority holds environmental information, disclosure of which would have some adverse effects on the separate interests served by more than one exception under Article 4(2) of the Environmental Information Directive, but it would not do so, in the case of either exception viewed separately, to any extent sufficient to outweigh the public interest in disclosure, the directive requires a further exercise involving the cumulation of the separate interests served by the two exceptions and their weighing together against the public interest in disclosure.
