Contractual Error vs. Duty to Verify Price in Sale Agreement

The case concerned a dispute arising from a contract where one party promised to sell an asset to another, but the seller later alleged a material error in the contract's price, seeking annulment based on a significant discrepancy between the intended and stated consideration. The court rejected the appeal, reasoning that the party alleging the error had an obligation to verify the contractual terms before signing, and since the contract was executed freely and in writing, the mere assertion of a subsequent discovery of a price disparity, without proof of fraud or a clearly established mutual mistake as to the object of the sale, was insufficient to justify nullification of the agreement.
