Case Summary (G.R. No. L-25494)

Key Dates

Execution of option: April 3, 1961.
Judicial deposit of purchase price by Sanchez: March 12, 1963.
Lower court judgment (Court of First Instance of Nueva Ecija): February 28, 1964 (judgment on the pleadings in favor of Sanchez ordering acceptance of the judicial consignment and execution of the deed; P200 attorney’s fees and costs).
Supreme Court decision: June 14, 1972.

Applicable Law and Constitutional Context

Applicable constitution at the time of decision: the 1935 Philippine Constitution (decision date 1972).
Governing statutory provisions: New Civil Code provisions, notably Article 1479 (promise to buy and sell/accepted unilateral promise binding if supported by consideration distinct from the price), Article 1324 (offer withdrawn before acceptance except when option founded upon consideration), and Article 1354 (presumptions regarding contracts generally). The case also relies on prior jurisprudence interpreting these provisions.

Procedural Posture

Sanchez deposited the P1,510.00 with the trial court and sued Rigos for specific performance and damages after Rigos rejected several tenders of payment within the option period. Rigos answered, admitting some allegations but asserting as a special defense that the unilateral promise lacked consideration and was void under the Civil Code. Both parties later jointly moved for judgment on the pleadings. The trial court granted judgment for Sanchez. Rigos appealed; the Court of Appeals certified the case to the Supreme Court on a pure question of law.

Contractual Instrument and Pleading Details

The annexed instrument (Annex A) labeled “Option to Purchase” expressly recited Rigos’s promise to sell within two years for P1,510.00 and stated that Sanchez’s right would lapse if he failed to exercise it within two years. The instrument also contained a clause that “I, NICOLAS SANCHEZ . . . hereby agree and conform with all the conditions set forth in this option to purchase executed in my favor; that I bind myself with all the terms and conditions.” Despite that recital, the Supreme Court treated the instrument as an option that did not, on its face, impose a reciprocal obligation to buy unless acceptance occurred creating reciprocal obligation.

Legal Issue Presented

Whether an accepted unilateral promise (an option to sell) unsupported by a consideration distinct from the price is binding on the promisor, and whether acceptance by the offeree before withdrawal can create a binding contract of sale despite the lack of separate consideration supporting the option.

Analysis of Article 1479 and Burden of Proof

Article 1479 provides that a promise to buy and sell is reciprocally demandable, and that “an accepted unilateral promise to buy or to sell a determinate thing for a price certain is binding upon the promissor if the promise is supported by a consideration distinct from the price.” The Court emphasized that, as to an accepted unilateral promise, Article 1479 expressly requires a consideration distinct from the price for the promise to be binding. Consequently: (1) Article 1479 governs specifically the promise-to-sell context and controls over the more general presumptions of Article 1354; (2) the promisee bears the burden of proving the existence of the required distinct consideration; and (3) where the promisor expressly pleads lack of such consideration as a defense, and the plaintiff seeks judgment on the pleadings without proving otherwise, the promisor’s averment must be taken as admitted for purposes of the motion on the pleadings.

Conflict in Precedents and Statutory Harmony

The Court discussed conflicting earlier decisions. Southwestern Sugar & Molasses Co. v. Atlantic Gulf & Pacific Co. had held that Article 1479 modified Article 1324 so that an accepted option without consideration remains withdrawable. By contrast, Atkins, Kroll & Co., Inc. v. Cua Hian Tek held that an option, although unilateral and unsupported by separate consideration, may be treated as an offer which, if accepted before withdrawal, generates a bilateral contract of sale. The Supreme Court concluded that Articles 1324 and 1479 should be reconciled and harmonized rather than treated as in direct conflict. The Court favored the Atkins, Kroll approach as a construction that avoids exception-driven disruption of general offer-and-acceptance principles and preserves statutory harmony.

Final Reasoning and Application to the Facts

Applying the harmonizing approach, the Court treated the unilateral option unsupported by separate consideration as a mere offer to sell. If the offeree accepts before the offeror withdraws, acceptance cr
