Substantial vs Minor Breach of Contract: What Philippine Law Requires

In Philippine law, not every violation of a contract gives the injured party the right to cancel it. The Supreme Court has long distinguished between substantial breaches—those that defeat the very purpose of the agreement—and slight or casual ones, which do not. This distinction was recently clarified in Nolasco v. Cuerpo (G.R. No. 210215, December 9, 2015), a case that also illustrates an important procedural rule: a party cannot change its legal theory on appeal.

The Case: A Contract to Sell and a Delayed Title Transfer

The petitioners and respondents entered into a Contract to Sell over a parcel of land in Rodriguez, Rizal. The buyers paid a down payment and issued post-dated checks for the balance. One provision of the contract (paragraph 7) required the sellers to complete the transfer of the title to their names within 90 days from signing. If they failed, the buyers were authorized to undertake the transfer themselves and charge the costs against the monthly amortizations.

The buyers later sent a letter seeking to rescind the contract, citing financial difficulties. When the sellers did not respond, the buyers filed a complaint for rescission. The trial court and the Court of Appeals both ruled in favor of the buyers, finding that the sellers' failure to transfer the title within 90 days was a substantial breach warranting rescission under Article 1191 of the Civil Code.

The Issue: Was the Breach Substantial?

The Supreme Court reversed. While the sellers indeed failed to perform their obligation under paragraph 7, the Court held that this failure did not constitute a substantial breach. The key reason: the contract itself provided a remedy for that specific failure—the buyers could cause the transfer themselves and charge the costs to the sellers. Because the parties had already agreed on what would happen if the sellers did not act within 90 days, the failure did not defeat the object of the agreement.

The Court reiterated the rule that rescission under Article 1191 is not permitted for a slight or casual breach, but only for substantial and fundamental violations that defeat the very object of the parties in making the agreement. Whether a breach is substantial depends on the attending circumstances of each case.

The Procedural Lesson: No New Theories on Appeal

The Court also addressed the sellers' prayer to cancel the contract and forfeit the buyers' payments due to the buyers' failure to pay monthly amortizations. The Court refused to grant this relief because the sellers never prayed for it in their pleadings before the trial court. Worse, they were declared in default for failing to file a pre-trial brief, so they presented no evidence in support of their defense.

The Court applied the settled rule that a party cannot change its theory of the case on appeal. A judgment that goes beyond the issues is irregular and invalid. Points of law and arguments not raised before the lower court will not ordinarily be considered on appeal.

Practical Takeaways

• Not every breach justifies rescission. A breach must be substantial—it must defeat the object of the parties in entering the contract—before the injured party may rescind under Article 1191 of the Civil Code.
• Read the contract's own remedies. If the contract provides a specific remedy for a particular failure (such as allowing the other party to perform the obligation and charge the costs), that failure may not be considered substantial.
• The question depends on circumstances. There is no fixed formula for what counts as substantial; courts look at the attending circumstances of each case.
• Raise all claims before the trial court. A party cannot raise new theories, issues, or arguments for the first time on appeal. This would be unfair to the adverse party and offensive to due process.
• Default has consequences. Failing to file required pleadings, like a pre-trial brief, can result in being declared in default and losing the chance to present evidence.
