Spouses Antonio and Beatriz Gonzales sold a parcel of land to Victoria Santos for ₱5,000,000.00 as evidenced by a notarized Deed of Absolute Sale dated March 15, 2023. The deed contained an integration clause stating: "This instrument contains the entire agreement between the parties and supersedes all prior negotiations, understandings, and agreements." Victoria filed an action for specific performance to compel the Gonzales spouses to deliver the title and possession of the property. In their answer, the Gonzales spouses admitted executing the deed but alleged as an affirmative defense that there was an oral agreement that the sale was subject to a suspensive condition—that Victoria would first secure approval of her housing loan application within 90 days, and if the loan was not approved, the sale would be rescinded and Victoria would return the land. They sought to present testimony about this alleged oral condition. Victoria objected, invoking the parol evidence rule. Should the objection be sustained? Explain your answer. (Bar 2026 Syllabus)
