Kernrechtsfrage
Whether the planned construction could be prohibited because it would encroach on the registered right of way.
Extrahierter Entscheid
Yes. The building would occupy part of the servient area and definitively prevent passage there.
Extrahierte Begründung
Under Art. 737(3) CC the servient owner may not do anything that hinders the exercise of the servitude; the planned structure would block the passage area.
