Kernrechtsfrage
Whether the appellants had standing to appeal the Federal Administrative Court judgment
Extrahierter Entscheid
They lacked standing because the prior ElCom decision had become final vis-à-vis them and the appellate judgment affected only the parties before the lower court.
Extrahierte Begründung
Only the legal relationship between swissgrid and the appealing network owner was in dispute below; non-appealing owners were neither parties nor materially affected by that judgment.
