Question juridique clé
Whether the parties' relationship included a separate consulting contract subject to mandate law, or only a sales relationship including pre-contractual advice.
Solution extraite
The recommendation was inseparable from the sales relationship and was governed exclusively by sales law; no separate consulting contract existed.
Motifs extraits
Advice and product recommendations made in the usual course of pre-contractual negotiations became part of the purchase agreement and did not justify an independent mandate-based relationship.
