“The clear intention of the drafters, …. was to craft a definition [of environmental information] that would be as broad in scope as possible, a fact that should be taken into account in its interpretation.”
“49. Therefore, if the effective protection of European Union environmental law is not to be undermined, it is inconceivable that article 9(3) of the Aarhus Convention be interpreted in such a way as to make it in practice impossible or excessively difficult to exercise rights conferred by European Union law. 50. It follows that, in so far as concerns a species protected by European Union law, and in particular the Habitats Directive, it is for the national court, in order to ensure effective judicial protection in the fields covered by European Union environmental law, to interpret its national law in a way which, to the fullest extent possible, is consistent with the objectives laid down in article 9(3) of the Aarhus Convention.”
“44. These arguments raise potentially important and difficult issues which may need to be decided at the European level. For the present we are content to proceed on the basis that the Convention is capable of applying to private nuisance proceedings such as in this case. However, in the absence of a Directive specifically relating to this type of action, there is no directly applicable rule of Community law. The UK may be vulnerable to action by the Commission to enforce the Community's own obligations as a party to the treaty. However, from the point of view of a domestic judge, it seems to us (as the DEFRA statement suggests) that the principles of the Convention are at the most something to be taken into account in resolving ambiguities or exercising discretions (along with other discretionary factors including fairness to the defendant).”
“ii). Certain EU Directives (not applicable in this case) have incorporated Aarhus principles, and thus given them direct effect in domestic law. In those cases, in the light of the Advocate-General's opinion in the Irish cases, the court's discretion may not be regarded as adequate implementation of the rule against prohibitive costs. Some more specific modification of the rules may need to be considered. iii). With that possible exception, the rules of the CPR relating to the award of costs remain effective, including the ordinary "loser pays" rule and the principles governing the court's discretion to depart from it. The principles of the Convention are at most a matter to which the court may have regard in exercising its discretion. iv). This court has not encouraged the development of separate principles for "environmental" cases (whether defined by reference to the Convention or otherwise). In particular the principles governing the grant of Protective Costs Orders apply alike to environmental and other public interest cases. The Corner House statement of those principles must now be regarded as settled as far as this court is concerned, but to be applied "flexibly". Further development or refinement is a matter for legislation or the Rules Committee.”
“32. It is unnecessary to rehearse the authorities which deal with the application of Corner House principles. The threads are drawn together in Morgan’s case…. Although the principles must be applied flexibly, they are settled so far as this court is concerned. However, this court has not had to consider whether those principles do comply with the requirements of art 10a in a case where the Directive applies. It is common ground that the Directive has a direct effect in our domestic law. In such a case, the Court of Appeal recognised in Morgan’s case (see[2009] 2 P & CR 30 at [47](ii)) that some more specific modification of our domestic costs rules may be required. 33. There is no dispute that the decision to grant planning permission in the present case is a decision to which the Directive applies. The council required that an EIA should accompany the planning application. It seems to me, therefore, that we must modify the Corner House conditions in so far as it is necessary to secure compliance with the Directive, but only in so far as it is necessary to secure such compliance.”
“39. In our view, therefore, the Article 9.4 obligation is no more than a factor to take into account when deciding whether to grant a PCO. It reinforces the need for the courts to be alive to the wider public interest in safeguarding environmental standards when considering whether or not to grant a PCO.”
