Kernrechtsfrage
Whether the state-rights complaint was admissible beyond requests for annulment and whether the Federal Court could review the cantonal referendum preparation decision.
Extrahierter Entscheid
The complaint was admissible only to the extent it sought annulment; broader requests were inadmissible because the remedy is generally cassatory.
Extrahierte Begründung
The challenged act concerned voting rights and was not subject to a cantonal remedy, but the complaint could only attack the decision itself, not request further substantive relief.
