Kernrechtsfrage
Whether the federal court could review the cantonal safety condition only by constitutional complaint, not administrative appeal.
Extrahierter Entscheid
The fence condition was based on independent cantonal building law, so only the constitutional complaint was available.
Extrahierte Begründung
The measure rested on cantonal safety rules applicable generally and lacked a sufficient nexus to Art. 24 ff. RPG to open administrative judicial review.
