Questione giuridica chiave
Whether the appeal against the cantonally final decision on material expropriation was admissible as an incidental decision
Decisione estratta
The decision was an appealable interim decision because allowing the appeal could immediately end the compensation dispute and avoid substantial evidentiary costs.
Motivazione estratta
The lower courts decided only a preliminary question, not separate claims. Under Art. 93 BGG, the requirements for immediate review were met because denying material expropriation would end the case at once.
