Contract Dispute and Unjust Enrichment Claim Regarding Third-Party Payment

The case involved a dispute arising from a contract where one party, claiming to have made a payment to a third party under the belief that it was necessary to secure a debt owed by the other contracting party, sought reimbursement based on unjust enrichment. The Court of Cassation rejected the appeal, reasoning that the trial court correctly determined that the payment made by the appellant to the third party was not an act of management of affairs (gestion d'affaires) nor a payment of a debt that was not due, as the appellant had not proven the payment was made in the sole interest of the debtor or under circumstances that would legally compel the debtor to reimburse the payment, thus precluding a claim for unjustified enrichment.
