Real Estate Contract Enforcement Despite Unstipulated Administrative Authorization

The dispute arose from a real estate transaction where a purchaser, after promising to acquire the property, subsequently refused to execute the final deed, claiming the seller had failed to provide the necessary administrative authorization for the transfer, despite this requirement not being explicitly stipulated in the preliminary agreement. The court upheld the lower court's decision, reasoning that since the preliminary contract did not contain a specific clause making the formalization of the sale conditional upon obtaining the administrative authorization, the purchaser could not use the non-obtention of that authorization as a legitimate ground to refuse to proceed with the sale, thereby justifying the seller's claim for contract enforcement or damages.
