Interplay between planning maintenance provisions for completed projects and substantive claims under the Federal Environmental Impact Assessment Act in revision admissibility proceedings

The Federal Administrative Court admitted the appeal on points of law, granting the petitioner's request and ruling that the constitutional complaint against the higher administrative court's refusal to allow the appeal was well-founded. The dispute concerned an objection to an environmental impact assessment or project authorization, specifically challenging the interplay between mandatory maintenance regulations for a completed, planned facility and the procedural rights of affected parties under the Federal Environmental Impact Assessment Act. The decisive legal basis for the decision was § 132 Abs. 2 Nr. 1 VwGO, which permits an appeal due to the fundamental legal significance of determining how planning maintenance provisions interact with substantive claims under § 4 Abs. 1 Satz 1 UmwRG for structures that are already built.
