Kernrechtsfrage
Whether a material expropriation claim must be assessed based on the final entry into force of the ownership restriction
Extrahierter Entscheid
Yes. The decisive date is when the ownership restriction entered into force and became final.
Extrahierte Begründung
For material expropriation, the court looks to the legal and factual situation at the time the restriction takes effect. Here, the individual decision creating the protected zone became final only at the end of September 1991.
