Whether the complaint was admissible despite the referendum process not yet having taken place.
Decisione estratta
No binding decision existed yet because the optional referendum had not been completed; the complaint was filed too early.
Motivazione estratta
A cantonal spending decision subject to optional referendum becomes binding only after the referendum period lapses or approval by popular vote. Before that, there is no appealable act under Art. 82 lit. a BGG.
