Kernrechtsfrage
Whether the railway tunnel and operation gave rise to a compensable post hoc expropriation claim under Art. 41(1)(b) EntG
Extrahierter Entscheid
No compensable claim existed because the tunnel had been lawfully built long before on state-controlled subsoil and the railway operation had not created any unforeseeable additional burden.
Extrahierte Begründung
The tunnel was authorized by the federal concession, built before any private interest extended to that depth, and no later operational intensification or new structural changes were shown. Art. 41(1)(b) EntG requires a later, compensable increase in burden attributable to the expropriator's conduct.
