Key legal question
Whether Frau Wietlisbach qualified as a merchant woman and was therefore personally subject to enforcement under Art. 35 OR.
Extracted holding
She did not qualify as a merchant woman because the legally required husband's consent to the alleged business activity was not established.
Extracted reasoning
No express consent was shown, and the file did not support implied authorization. The submitted letters and invoices related only to isolated purchases from the appellant and did not prove business activity directed to a broader clientele.
