Key legal question
Whether a brokerage contract existed between X. and Y. SA
Extracted holding
Yes. X. accepted a 3% commission offer, and Y. SA acted as the broker; no other intermediary was shown to have performed that role.
Extracted reasoning
The handwritten approval on the letter of 20 December 2004 bound the parties. The factual findings established that Y. SA presented the buyer and that contrary indications about other intermediaries were not supported.
