Seller's Right to Dissolve Preliminary Sale Agreement Due to Buyer's Non-Performance

A claim arose concerning the transfer of ownership of an immoveable property following a preliminary promise to sell, where the prospective buyer failed to conclude the final deed of sale by the specified date, despite the seller being ready to perform, leading the seller to invoke the dissolution of the promise and seek damages. The court upheld the lower court's decision to dismiss the buyer's claim for forced execution, reasoning that the unilateral failure of the beneficiary to complete the stipulated acts within the agreed timeframe, without valid justification, constitutes a fundamental breach of the preliminary agreement, thereby justifying the seller's invocation of the dissolution clause and rendering the buyer ineligible for the requested specific performance.
