Kernrechtsfrage
Whether the appeal court violated the right to be heard by deciding the lease-extension length without a full double review at two cantonal levels.
Extrahierter Entscheid
No. The constitutional right to be heard does not guarantee a cantonal double-instance review, and the appeal court could decide the extension length on the available record.
Extrahierte Begründung
The court held that the claimed double-degree principle is not part of Art. 29(2) Cst.; the appeal court could complement evidence under cantonal procedure and had sufficient elements for the balancing required under lease-extension law.
