Kernrechtsfrage
Whether the reform appeal against the cantonal ruling on passive standing is admissible as an interim decision.
Extrahierter Entscheid
The challenge to passive standing is inadmissible because it concerns a prejudicial, not final, decision and the strict conditions for immediate appeal were not met.
Extrahierte Begründung
A decision on passive standing does not finally dispose of part of the dispute. Under Art. 50 OG, immediate review requires that a final decision can be caused and that evidence would be lengthy and costly; those requirements were not shown.
