PNCC vs. Mars Construction Enterprises

Unilateral rescission of a contract is merely provisional and subject to judicial determination; the party who rescinds without court action does so at its own risk, and only a final judgment will conclusively settle whether the rescission was proper. Additionally, contractual stipulations must be interpreted together, with ambiguous provisions construed to favor the greatest reciprocity of interests, and the quantities specified in a supply contract's scope-of-services provision are deemed minimum deliverables when such interpretation best serves mutuality of obligation.

Mars Construction Enterprises, Inc. (respondent) entered into a subcontract agreement with Construction & Development Corporation of the Philippines (CDCP), later reorganized into the Philippine National Construction Corporation (PNCC, petitioner), for the supply of concrete aggregates needed for the Philphos Project. The original agreement and two subsequent amendments defined the scope of services, delivery schedules, and default provisions governing the parties' respective obligations. The subcontract contemplated the supply of approximately 70,000 cubic meters of aggregates, with Amendment No. 2 specifying a breakdown among washed sand, washed 3/4" gravel, washed 1-1/2" gravel, and sub-base material, and establishing a minimum monthly delivery rate until the project's aggregate requirements were fully satisfied.

On July 2, 1982, Mars Construction Enterprises, Inc. entered into a subcontract agreement with Construction & Development Corporation of the Philippines (CDCP), later reorganized into the Philippine National Construction Corporation (PNCC), for the supply of approximately 70,000 cubic meters of concrete aggregates consisting of washed sand, washed 3/4" gravel, washed 1-1/2" gravel, and sub-base material. On August 7, 1982, the parties executed Amendment No. 1, increasing the third-party liability coverage from ₱50,000 to ₱100,000. On November 5, 1982, they executed Amendment No. 2, which revised the scope of services to specify approximate quantities: 17,500 cubic meters of washed sand, 17,500 cubic meters of washed 3/4" gravel, 35,000 cubic meters of washed 1-1/2" gravel, and sub-base 2" minus crusher run (the quantity of which was left unspecified). Amendment No. 2 also altered the delivery clause to require respondent to deliver a minimum of 6,000 cubic meters of combined concrete aggregate per month until the entire requirements of petitioner to complete the Philphos Project had been satisfied.

Actual delivery of aggregates commenced only in March 1983, representing a delay of eight months beyond the 45 days originally stipulated. There were further non-deliveries between June 1983 and January 1984. Petitioner was thus constrained to procure materials from other sources, incurring additional costs representing the difference between the agreed price of ₱140.00 per cubic meter and the pricing of outside suppliers. Pursuant to the default clause in the contract, respondent reimbursed petitioner for these excess procurement costs, paying a total of ₱1,578,000.

The controversy arose when petitioner refused to accept respondent's delivery of 17,000 cubic meters of washed 1-1/2" gravel, asserting that it no longer needed the material. Respondent claimed ₱680,000 representing lucrum cessans or unrealized profit, plus interest, exemplary damages, and attorney's fees. Respondent likewise demanded payment of ₱118,518.68, representing the balance on the purchase of 39,200.62 cubic meters of base course after deducting half of an overpayment of ₱23,256.80. Petitioner denied breaching the contract and counterclaimed for ₱85,120 as price differential of procurement costs over the agreed price, plus reimbursement of the ₱23,256.80 overpayment arising from an error in measurement.

The trial court rendered judgment in favor of respondent, ordering petitioner to pay ₱680,000 as lucrum cessans, ₱33,387.91 as the outstanding obligation (₱118,518.68 less the price differential of ₱85,120.77), and ₱50,000 as attorney's fees, plus costs of litigation. The Court of Appeals affirmed the RTC decision in toto, holding that the contract and its amendments compelled petitioner to accept delivery of the washed 1-1/2" gravel, that the figures in the scope-of-services provision constituted minimum quantities, and that petitioner had utilized only 18,140.49 cubic meters of washed 1-1/2" gravel — approximately half of the stipulated 35,000 cubic meters — thereby breaching the contract when it refused the remaining delivery.

• Obligation to Accept Delivery: Petitioner contended that it was not obligated to accept the 17,000 cubic meters of washed 1-1/2" gravel, because delivery was made after the project's actual aggregate requirement had already been fully satisfied and after respondent had defaulted on its contractual undertakings. Petitioner asserted that respondent had already delivered aggregates whose combined volume was about 45 percent over and above the total required under Article I of Amendment No. 2, rendering the refused delivery "excess."
• Unilateral Termination by Advisory Letter: Petitioner maintained that its Project Director H. R. Taylor's letter of May 17, 1984, which informed respondent of the final quantities of concrete aggregates to be delivered and advised that no further deliveries would be accepted, effectively released it from any obligation to accept additional deliveries.
• Default as Justification for Refusal: Petitioner argued that respondent was already in default when it refused the 17,000 cubic meter delivery, and that such default justified the refusal and the rescission of the contract.
• Speculative Lost Profits: Petitioner averred that the profits respondent expected to derive from the agreement were purely speculative, and that the trial and appellate courts erroneously relied on the bare testimony of respondent's general manager, Mr. Solomon Chu, regarding said profits.

• Obligation to Accept Delivery: Whether petitioner was obligated to accept and pay for the 17,000 cubic meters of washed 1-1/2" gravel delivered by respondent, notwithstanding petitioner's claim that the project's aggregate requirements had already been satisfied and that respondent had defaulted.
• Validity of Unilateral Rescission: Whether petitioner's unilateral advisory letter effectively terminated or modified its contractual obligation to accept further deliveries from respondent.
• Award of Lost Profits: Whether the award of ₱680,000 as lucrum cessans was proper, given petitioner's contention that the expected profits were purely speculative.

• Obligation to Accept Delivery: Yes. The quantities specified in Amendment No. 2 constituted minimum deliverables, not mere estimates, and both parties were bound by these figures. Petitioner having utilized only 18,140.49 cubic meters of washed 1-1/2" gravel — far short of the stipulated 35,000 cubic meters — it was obligated to accept the remaining 16,859.51 (approximately 17,000) cubic meters.
• Validity of Unilateral Rescission: No. The contract did not authorize petitioner to limit deliveries by unilateral advice. Unilateral rescission is merely provisional and subject to judicial determination; petitioner, having rescinded without court action, proceeded at its own risk.
• Award of Lost Profits: Yes. The question of whether respondent failed to realize profits and how much was lost is factual in nature. Factual findings of the trial court, especially when affirmed by the Court of Appeals, are binding and conclusive on the Supreme Court.

• Obligation to Accept Delivery: The various stipulations in a contract must be interpreted together, and ambiguous provisions should be construed to conform to the sense that results when all provisions are comprehended jointly, pursuant to Article 1374 of the Civil Code. The scope-of-services provision in Amendment No. 2 specified 35,000 cubic meters of washed 1-1/2" gravel out of a total 70,000 cubic meters, but left the quantity of sub-base unspecified, creating ambiguity. The trial court correctly interpreted the specified quantities as minimum deliverables: petitioner had ordered more than the aggregate total specified, demonstrating that the 70,000 cubic meter figure was not treated as a maximum, and the breakdown quantities thus represented minimum obligations. Interpreting the figures as mere estimates would have been too burdensome on respondent, leaving it uncertain as to how much to deliver. Under Article 1378 of the Civil Code, doubts in contracts should be settled in favor of the greatest reciprocity of interests. Since petitioner procured only 18,140.49 cubic meters of washed 1-1/2" gravel from all sources (9,978.06 from other suppliers and 8,162.43 from respondent), respondent had the prerogative to supply, and petitioner was bound to accept, the remaining 16,859.51 cubic meters. Parties are bound to the fulfillment of what has been expressly stipulated.

• Validity of Unilateral Rescission: The only delivery clause in the contract — Stipulation 2 of Amendment No. 2 — required respondent to deliver a minimum of 6,000 cubic meters per month until the entire requirements of petitioner to complete the Philphos Project had been satisfied. The contract did not authorize petitioner to unilaterally limit the quantity of aggregates to be delivered. Petitioner's Project Director's letter of May 17, 1984, advising that no further deliveries would be accepted, constituted a unilateral amendment of the contract. The act of treating a contract as cancelled or rescinded on account of infractions by the other party is always provisional — contestable and subject to judicial determination. Judicial action is necessary to afford the other party an opportunity to be heard and to determine if the rescission was proper. When petitioner rescinded the agreement without previous court action, it proceeded at its own risk; only a final judgment would conclusively settle whether such recourse was correct. Moreover, respondent's defaults did not constitute a substantial breach justifying rescission, because the contract specifically provided that petitioner could procure aggregates from other sources in case of respondent's failure to deliver, and respondent had already paid ₱1,577,000 in penalties for such defaults. Having exercised its option to procure from other sources and imposed penalties, petitioner waived its right to rescind and was estopped from rescinding the contract by reason of short delivery.

• Award of Lost Profits: Whether respondent failed to realize profits — and if so, how much — and whether the judgment was supported by the evidence presented are questions factual in nature. Factual findings of the trial court, especially when affirmed by the Court of Appeals, are binding and conclusive on the Supreme Court, which is not tasked to reexamine lower courts' findings of fact. While exceptions to this rule exist, petitioner failed to demonstrate entitlement to any of them.

• Principle of Joint Interpretation of Contractual Stipulations (Article 1374, Civil Code) — The various stipulations in a contract should be interpreted together. Ambiguous ones should be construed to conform to the sense that would result if all provisions are comprehended jointly. The Court applied this doctrine to hold that the quantities specified in Amendment No. 2's scope-of-services provision constituted minimum deliverables, reading the delivery clause and the scope-of-services clause together rather than in isolation.

• Greatest Reciprocity of Interests (Article 1378, Civil Code) — Doubts in contracts should be settled in favor of the greatest reciprocity of interests. The Court invoked this principle to reject petitioner's interpretation that the breakdown quantities were mere estimates, holding that such interpretation would have been too burdensome on respondent and would have left it uncertain as to how much to deliver.

• Provisional Nature of Unilateral Rescission — The act of treating a contract as cancelled or rescinded on account of infractions by the other contracting party is always provisional, contestable, and subject to judicial determination. Judicial action is necessary to afford the other party an opportunity to be heard and to determine if the rescission was proper. A party who rescinds without court action does so at its own risk; only a final judgment conclusively settles whether the rescission was correct in law.

• Waiver and Estoppel by Exercise of Contractual Remedies — When a party exercises its contractual options in case of delay or default by the other party — such as procuring materials from other sources and imposing penalties — it waives its right to rescind and is estopped from rescinding the contract by reason of such short delivery. The Court applied this doctrine to hold that petitioner, having already been compensated for respondent's defaults through the penalty mechanism, could not treat those defaults as a substantial breach justifying rescission.

• Binding Nature of Factual Findings of Lower Courts — Factual findings of the trial court, especially when affirmed by the Court of Appeals, are binding and conclusive on the Supreme Court. While exceptions exist, the petitioner must demonstrate entitlement to one; absent such showing, the Court will not reexamine lower courts' findings of fact.

• "Unilateral rescission of a contract is subject to judicial determination." — This opening statement of the decision encapsulates the core doctrinal ruling: a party cannot unilaterally and conclusively rescind a contract without judicial validation.

• "The act of treating a contract as cancelled or rescinded on account of infractions by the other contracting party is always provisional; that is, contestable and subject to judicial determination. Judicial action is necessary for its rescission in order to afford the other party an opportunity to be heard and to determine if the rescission was proper. When the herein petitioner resolved or rescinded the Agreement without previous court action, it proceeded at its own risk. Only the final judgment of a court will conclusively and finally settle whether such recourse was correct in law." — This passage articulates the full ratio decidendi on unilateral rescission, defining its provisional character and the necessity of judicial action, and is the formulation most frequently cited in subsequent jurisprudence on the subject.

• "Doubts should be settled in favor of the greatest reciprocity of interests." — This formulation of the interpretive principle under Article 1378 of the Civil Code was applied to resolve the ambiguity in the scope-of-services provision, favoring an interpretation that imposed mutual and definite obligations on both parties.

• "Since petitioner was already compensated for respondent's defaults, such defaults cannot be considered as a substantial breach that justified the rescission of the Contract and the refusal to accept the questioned delivery. Furthermore, when the petitioner exercised its options in case of delay or default on the part of the respondent, the former waived its right to rescind and was thus estopped from rescinding the Contract by reason of such short delivery." — This passage establishes the doctrine that exercising contractual remedies for default precludes subsequent rescission based on the same breach, applying principles of waiver and estoppel to contractual defaults.

• University of the Philippines vs. De los Angeles, 35 SCRA 102 (1970) — Controlling precedent on the provisional nature of unilateral rescission. The Court relied on this case to establish that treating a contract as rescinded is always provisional and subject to judicial determination.
• Ocejo, Perez & Co. vs. International Banking Corp., 37 Phil. 631 (1918) — Cited in support of the proposition that judicial action is necessary for rescission to afford the other party an opportunity to be heard.
• Republic vs. Hospital de San Juan de Dios, 84 Phil. 820 (1949) — Cited for the same proposition regarding the necessity of judicial determination of rescission.
• Coronel vs. Court of Appeals, 263 SCRA 15 (1996) — Cited in the line of authorities supporting the requirement of judicial action for rescission.

• Siska Dev't. Corp. vs. Office of the President of the Phil., 231 SCRA 674 (1994) — Cited for both the proposition that compensated defaults do not justify rescission and that exercising contractual remedies for default constitutes a waiver of the right to rescind.
• Angeles vs. Calasanz, 135 SCRA 323 (1985) — Cited in support of the waiver-and-estoppel doctrine when a party exercises its options for delay or default.
• Romero vs. Court of Appeals, 250 SCRA 223 (1995) — Cited for the principle that parties to a contract are bound to the fulfillment of what has been expressly stipulated.

• Article 1374, Civil Code — Provides that contractual stipulations should be interpreted together, with ambiguous ones construed to conform to the sense resulting from all provisions comprehended jointly. Applied to interpret the scope-of-services and delivery clauses of Amendment No. 2 in conjunction, leading to the conclusion that the specified aggregate quantities were minimum deliverables.
• Article 1378, Civil Code — Provides that doubts in contracts should be settled in favor of the greatest reciprocity of interests. Applied to reject petitioner's interpretation that the breakdown quantities were mere estimates, which would have been too burdensome on respondent, and to hold instead that both parties were bound by definite minimum quantities.
