Brokerage Commission Ratification of Voidable Mandate

The court addressed a claim for a brokerage commission arising from a mandate signed by a single individual who held only collective signatory power for the represented entity, meaning the contract was initially voidable under relevant commercial law provisions. The court reasoned that despite the initial lack of authority, the contract was deemed subsequently ratified because the claimant engaged in numerous subsequent meetings concerning the transaction where other authorized representatives participated without challenging the mandate, and crucially, the claimant explicitly referred to the validity of the original agreement in correspondence that remained unchallenged by the entity, establishing binding tacit approval based on good faith and commercial custom, thereby entitling the claimant to the commission.
