Seller Breach and Failure to Issue Formal Notice in Land Sale Dispute

The case involved a dispute over a contract for the sale of land where the seller failed to fulfill their obligation to transfer title by the agreed date, leading the buyer to seek termination of the sale and damages. The Court of Cassation quashed the lower court's decision because, despite the seller's demonstrable breach, the lower court had failed to properly establish that the buyer had formally put the seller in default through a formal notice (mise en demeure) before seeking judicial resolution, which is a prerequisite for enforcing contractual remedies concerning performance delays.
