Key legal question
Whether G.________ bound B.________ by allegedly promising to pay A.________ SA's invoices despite having only collective signature on record.
Extracted holding
No. The court held that the findings did not show a valid individual mandate, ratification, or other exception to the collective-signature rule.
Extracted reasoning
The alleged internal discretion concerned only limited ordering of materials, was not shown to cover the disputed payment commitment, and the testimony did not make the cantonal court's factual assessment arbitrary.
