Kernrechtsfrage
Whether the appellants could directly seize the Federal Commission of Valuation with expropriation claims and a request for formal expropriation proceedings.
Extrahierter Entscheid
No. The commission could not be directly seized because the expropriating authority had not yet opened an expropriation procedure and the statutory prerequisites for direct access were not met.
Extrahierte Begründung
Under the Expropriation Act, claims are generally brought after the expropriating authority opens the procedure. Direct recourse by property owners is exceptional and requires specific statutory bases, which were absent here.
