Seller's Valid Exercise of Preemption Right in Apartment Sale Dispute

The case involved a dispute arising from a contract for the sale of an apartment where the seller, upon learning of the buyer's subsequent resale agreement with a third party, exercised a right of preemption, leading to litigation over the validity of the initial sale and the subsequent preemption exercise. The court found that the seller's exercise of the right of preemption was valid because the initial sale, although conditioned on the buyer not having exercised a prior right of first refusal, was nevertheless a firm commitment, and the subsequent resale by the buyer triggered the seller's right, compelling the court to quash the lower court's decision which had ruled against the seller.
