Questione giuridica chiave
Whether the party compensation had to be determined according to UVEK criteria agreed in the settlement contract or under Art. 115 EntG.
Decisione estratta
The compensation had to be fixed solely under Art. 115 EntG; the parties could not bind the Schätzungskommission to external criteria.
Motivazione estratta
Once the Schätzungskommission is seized, it acts as a state court within its statutory powers only. There is no expropriation arbitration procedure allowing the parties to define the decision criteria.
