Property Sale Rescission Requires Specific Valuation for Lesion Claim

A party sought to nullify a property sale alleging a significant lesion, meaning the price received was less than half the true value, a ground permitted for rescission under the civil code for immovable property sales. The Court of Cassation quashed the lower court's decision, reasoning that for an action in rescission based on lesion to be admissible, the claimant must specifically establish the precise value of the property at the time of the sale, and mere general claims or expert opinions not clearly quantifying this value are insufficient to support the necessary legal threshold for invoking the remedy.
