Abstract The article analyzes the cjeu Judgment in the A. Flausch et al case, which concerns the compatibility of the Greek procedural rules relating to specific aspects of the public participation in the eia context and to a specific aspect of access to justice (time limit) with the respective EU Law provisions in the face of the increasing use of digital technologies in the public participation procedures. This ruling is important, because it sets limits to the procedural autonomy of ms when it comes to the rules that are applied to the eia-related disputes and those that concern the public participation arrangements. It demonstrates, though, the lack of a steady line in the Court’s jurisprudence concerning the standards for assessing the national procedural rules and the role of Article 47 cfr. Moreover, the Court did not lay the ground for an interpretation of the ΕU public participation provisions in a way that an obligation for taking measures could be established, with the aim to ensure equal participation opportunities.
