Kernrechtsfrage
Whether the appellants retained active standing to pursue the easement claim after selling the dominant parcel during the proceedings.
Extrahierter Entscheid
No. By transferring the right attached to the dominant parcel, the appellants lost active standing; without the purchaser's entry or an adapted claim, the action had to be dismissed.
Extrahierte Begründung
The substantive right to enforce the easement belongs to the holder of the right in the dominant property. Once that right is alienated, standing ends. The procedural effects of the pending transfer are governed by cantonal procedure; the cantonal court could validly choose a party-substitution model over process standstill, and no constitutional violation was shown.
