Kernrechtsfrage
Whether the respondent had standing to claim payment despite the appellant's challenge to contractual legitimacy
Extrahierter Entscheid
The contract of 9 December 2004 and its amendment established the respondent as contractual counterpart, so she had standing to sue.
Extrahierte Begründung
Ownership of the premises was irrelevant because a contract creates obligations only; the appellant could not rely on a prior agreement to which he was not a party.
