European Union – Environment. Where an applicant raised both pleas alleging infringement of the rules on public participation in decision-making in environmental matters and pleas alleging infringement of other rules, the requirement that certain judicial procedures not be prohibitively expensive laid down in art 11(4) of Directive (EU) 2011/92 applied only to the costs relating to the part of the challenge alleging infringement of the rules on public participation. The Court of Justice of the European Union so held, among other things, in a preliminary ruling in proceedings concerning the determination of costs associated with the rejection of an application for judicial review of the development consent process for the installation of an electricity interconnector.
