Tax Waivers and Faulty Agreements: When Buyers and Sellers Are Bound by Law

The Supreme Court's 2016 resolution in Buenavista Properties, Inc. v. Mariño (G.R. No. 212980) offers a clear lesson for property owners, developers, and buyers alike: agreements—even flawed ones—can bind parties in unexpected ways, and once a judgment becomes final, it is nearly impossible to overturn.

The case began when landowners entered into a Joint Venture Agreement (JVA) with La Savoie Development Corporation to develop a subdivision in Bulacan. The JVA gave La Savoie broad powers, including general management over marketing and sales, and appointed it as attorney-in-fact for the landowners. Later, the property was sold to Buenavista Properties, Inc. (BPI), which assumed the landowners' rights under the JVA.

In 1997, La Savoie sold a lot to Ramon Mariño under a Contract to Sell. Mariño fully paid for the lot in 2001. But BPI refused to execute the deed of sale, claiming La Savoie had exceeded its authority by selling without BPI's approval on pricing. BPI argued that the sale was unauthorized and that it was not bound by a contract it never signed.

The Issue

The central question was whether La Savoie had the authority to sell the lot to Mariño, and if so, whether that authority had been validly withdrawn before the sale. BPI insisted that the JVA only allowed La Savoie to "engage the services of brokers," not to sell lots directly. It also pointed to letters asking La Savoie to stop selling until they agreed on prices.

The Ruling

The Supreme Court denied BPI's petition and affirmed the lower courts' rulings. The Court examined the JVA provisions and found that La Savoie had full authority to manage sales, act as attorney-in-fact, and sell lots within the agreed period. The clause on engaging brokers was merely one of several powers, not a limitation.

More importantly, the Court held that BPI never categorically terminated the JVA or withdrew La Savoie's authority before the sale. The letters BPI sent merely requested a suspension of sales pending price negotiations. BPI's option to cancel the JVA became clear only on February 28, 1998, when it filed a case for rescission—seven months after Mariño signed the Contract to Sell. Thus, La Savoie still had authority to sell when it contracted with Mariño.

The Court also addressed the procedural aspect: BPI's second motion for reconsideration was a prohibited pleading under Section 2, Rule 52 and Section 4, Rule 56 of the Rules of Court. Once a judgment becomes final, it is immutable and may no longer be modified, even to correct errors of fact or law.

Why This Matters

This case underscores several important principles. First, parties must read contracts carefully—what looks like a limitation may actually be a grant of broad authority. Second, a party cannot claim a contract was terminated when its own letters show it was still negotiating. Third, the finality of judgments is a cornerstone of the legal system; parties cannot endlessly relitigate decided cases.

The Court also warned against improper interference with judicial processes, noting that parties must speak through their counsels.

Practical Takeaways

• Read contracts as a whole. A clause that appears to limit a party's authority may be just one of several powers granted elsewhere in the agreement.
• Terminate agreements in writing, clearly. Letters requesting a "pause" or "suspension" do not amount to cancellation. To withdraw authority, use explicit, unequivocal language.
• Act promptly. If a party believes a contract has been breached, it should invoke its remedies immediately. Delay can be fatal to a claim.
• Respect the finality of judgments. Once a decision becomes final and executory, it can no longer be changed. A second motion for reconsideration is generally prohibited.
• For buyers, payment is powerful. Under Section 25 of Presidential Decree No. 957, a buyer who fully pays is entitled to the delivery of the title, regardless of disputes between the developer and the owner.
