Kernrechtsfrage
Whether the cantonal courts violated the procedural maxims by ignoring the defendants' factual admissions about the tenancy relationship and partnership structure.
Extrahierter Entscheid
Yes. The appellate court wrongly treated the defendants' statement as only a legal opinion and failed to recognize an admission of the factual basis for the claim.
Extrahierte Begründung
Under § 54 Abs. 1 ZPO ZH, the court must accept undisputed factual allegations. The defendants' brief contained factual assertions that the in-Zurich lawyers jointly pursued the administration and operation of office premises and concluded the lease in that framework.
