Right of Preemption Trumps Subsequent Sale

An individual, having sold a property subject to a right of preemption held by a tenant, subsequently transferred the property to a third party despite the tenant exercising their right and formally notifying the buyer of their intention to acquire the property under the agreed terms. The buyer subsequently sought to annul the sale, arguing the prior agreement was null due to the seller's breach of the right of preemption, but the court dismissed the appeal, affirming that the exercise of a valid right of preemption effectively substitutes the beneficiary for the intended purchaser in the sale contract, rendering the transfer to the third party ineffective against the beneficiary and not grounds for annulling the sale between the original seller and the third party, as the seller's subsequent transfer was made in violation of the beneficiary's established right.
