Kernrechtsfrage
Whether the architect could bind the simple partnership and the defendant as co-partner for the plastering contract and approval of the final account.
Extrahierter Entscheid
Yes. The architect was authorized to conclude the contract and approve the adjusted final invoice on behalf of the simple partnership, which bound the partnership and therefore the defendant as partner.
Extrahierte Begründung
The lower courts’ uncontested findings established actual authority. Therefore the representation took effect directly under the law of representation; the plaintiff did not need to rely on apparent authority or on a trust-based theory.
