Questione giuridica chiave
Whether the reform appeal was admissible against the cantonal interlocutory decision on passive standing.
Decisione estratta
No; the decision was interlocutory, and the appellants failed to show that immediate federal review would avoid extensive and costly evidence proceedings.
Motivazione estratta
A final decision could theoretically result if passive standing were denied, but the second condition of Art. 50 OJ was not met because the further proceedings did not appear lengthy or expensive and the appellants did not demonstrate otherwise.
