The administrative appeal was inadmissible because the challenged ruling was an interim remand decision under federal environmental law and caused no irreparable harm.
Motivazione estratta
The cantonal court applied federal environmental protection law; however, its decision only sent the matter back for further noise-related clarification and did not finally determine the permit question.
