Sale Contract Upheld Despite Claim of Mutual Mistake Regarding Fixtures

A party, having executed a contract for the sale of property with a stipulation regarding fixtures that were to remain, subsequently sought judicial annulment of the sale based on a mutual mistake concerning the nature of those fixtures, asserting that the property transferred did not include what they believed to be essential, permanent parts of the structure. The court rejected the appeal, reasoning that the stipulation concerning the removal or retention of the items in question, being clearly set forth in the authentic deed of sale, established the parties' mutual understanding and intent regarding the property's condition at the time of sale, thereby precluding a successful claim of a unilateral or mutual mistake that would invalidate the underlying agreement.
