The Grand Chamber rules that "Article 9(3) of the Convention on access to information, public participation in decision-making and access to justice in environmental matters approved on behalf of the European Community by Council Decision 2005/370/EC of 17 February 2005 does not have direct effect in European Union law. It is, however, for the referring court to interpret, to the fullest extent possible, the procedural rules relating to the conditions to be met in order to bring administrative or judicial proceedings in accordance with the objectives of Article 9(3) of that convention and the objective of effective judicial protection of the rights conferred by European Union law, in order to enable an environmental protection organisation, such as the Lesoochranárske zoskupenie, to challenge before a court a decision taken following administrative proceedings liable to be contrary to European Union environmental law".
