Question juridique clé
Whether the mandate clause covered the commission from the later switch to a new insurance product and whether it had to be returned under Art. 400 OR.
Solution extraite
The earlier clause did not cover the later switch; the commission from the switch had to be returned and accounted for, subject to any reasonable remuneration for the related work.
Motifs extraits
The contract text referred to one insurance company and did not regulate a later switch. The court applied Art. 400 OR to the commission, and Art. 394(3) OR to determine a separate, objectively reasonable fee for the switch-related services.
