Kernrechtsfrage
Whether the tenant could file an independent second action for lease extension after the 30-day deadline expired.
Extrahierter Entscheid
No. After the statutory 30-day period, the tenant could raise requests only in the answer or by counterclaim, not by a separate second action.
Extrahierte Begründung
Art. 273(5) and Art. 274f(1) OR require the underlining party to seize the court within 30 days. The tenant let that deadline lapse. The fact that both parties had partly failed before the conciliation authority does not create a statutory basis for a later autonomous action.
