Void Sale Due to Unfulfilled Option Precondition

The case involved a dispute over the transfer of ownership of a construction site, where the buyer claimed the seller had transferred possession and the right to build, but the sale was later deemed void due to non-observance of a legal prerequisite concerning a prior option to purchase granted to a third party. The court upheld the lower court's decision, reasoning that while the parties intended to transfer possession and the right to build, the absolute nullity of the sale, arising from the failure to comply with the legal formalities regarding the existing option, prevented the intended transfer of ownership from taking place.
