Sale with Unexercised Option to Repurchase Upheld Against Disguised Loan Claim

An individual who sold a building and subsequently contracted to buy it back at a fixed price upon the seller's request, but failed to exercise this right within the stipulated period, sued the original buyer, arguing that the contract was a disguised loan secured by the property, seeking a declaration of nullity and the transfer of ownership. The court rejected this claim, reasoning that the contractual documents clearly established a sale followed by a valid option to repurchase, and absent any evidence of simulation or a fraudulent agreement intended to circumvent usury laws, the terms of the unambiguous agreements governing the sale and the lapsed option must be respected, thereby validating the transfer of ownership to the purchaser.
