Questão jurídica principal
Whether the public-law appeal was admissible and whether requests beyond annulment were permissible.
Decisão extraída
The appeal was admissible only against the cantonal final judgment on opposition and plan modification, but the request to annul the municipality's expropriation application was inadmissible because the remedy is purely cassatory.
Fundamentação extraída
Only the last cantonal instance had decided the challenged issues; however, public-law appeal cannot seek substantive relief beyond setting aside the judgment.
