Gonzalo vs. Tarnate, Jr.

The doctrine of in pari delicto does not preclude relief to a party to an illegal contract where rigid application thereof would result in unjust enrichment contrary to public policy, provided the party seeking recovery has performed his part of the agreement and the other party would otherwise retain a benefit at the former's expense without just or legal ground.

Gonzalo Construction, owned by petitioner Domingo Gonzalo, was awarded a contract by the Department of Public Works and Highways (DPWH) for the improvement of the Sadsadan-Maba-ay Section of the Mountain Province-Benguet Road. Without securing the required approval from the DPWH Secretary, Gonzalo subcontracted the supply of materials and labor to respondent John Tarnate, Jr., doing business as JNT Aggregates. To facilitate payment for equipment rental, Gonzalo executed a deed of assignment transferring to Tarnate the right to collect the 10% retention fee from the DPWH. Gonzalo subsequently unilaterally rescinded this assignment through an affidavit of cancellation, causing the DPWH to release the retention fee to Gonzalo instead of Tarnate.

• The DPWH Contract and Subcontract: On July 22, 1997, the DPWH awarded to Gonzalo Construction the contract for the improvement of the Sadsadan-Maba-ay Section of the Mountain Province-Benguet Road for ₱7,014,963.33. On October 15, 1997, petitioner Domingo Gonzalo subcontracted to respondent John Tarnate, Jr. the supply of materials and labor for the project under Tarnate's business, JNT Aggregates. The agreement stipulated that Tarnate would pay Gonzalo eight percent and four percent of the contract price upon Tarnate's first and second billing, respectively.
• The Deed of Assignment: On April 6, 1999, Gonzalo executed a deed of assignment assigning to Tarnate an amount equivalent to 10% of the total collection from the DPWH (₱233,526.13) representing rent for Tarnate's equipment utilized in the project. Gonzalo authorized Tarnate to use Gonzalo Construction's official receipt in processing documents for collection and to encash the check to be issued by the DPWH.
• Unilateral Rescission and Collection: The deed of assignment was submitted to the DPWH on April 15, 1999. However, on April 19, 1999, Gonzalo executed an affidavit of cancellation of the deed of assignment, which he filed with the DPWH on April 22, 1999. Consequently, the DPWH issued the disbursement voucher for the retention fee in Gonzalo's name and released the funds to him.
• Demand and Refusal: Tarnate demanded payment of the retention fee from Gonzalo, but Gonzalo refused. Tarnate alleged that Gonzalo's refusal was based on a purported condition that Tarnate should first pay Gonzalo's personal debt of ₱200,000.00 to Congressman Victor Dominguez, a condition Tarnate denied agreeing to and which Gonzalo failed to prove.
• Lower Court Proceedings: The RTC found the deed of assignment valid and ordered Gonzalo to pay the retention fee plus damages. The CA affirmed but held that both the subcontract and deed of assignment were illegal for lack of DPWH approval under Section 6 of Presidential Decree No. 1594, finding both parties in pari delicto but applying the exception to prevent unjust enrichment.

• In Pari Delicto: Gonzalo contended that both parties were equally guilty of entering into the illegal subcontract and deed of assignment, which were specifically prohibited by Section 6 of Presidential Decree No. 1594. He argued that the courts below should have applied the doctrine of in pari delicto, leaving the parties where they stood and denying relief to either.
• Void Deed of Assignment: Petitioner maintained that the deed of assignment was void and unenforceable because it was a mere product of the illegal subcontract, which could not stand independently. He argued that an illegal agreement cannot give birth to a valid contract.
• Lack of Arbitration: Gonzalo raised non-compliance with the arbitration clause in the subcontract as a procedural defect.

• Unjust Enrichment: Tarnate argued that Gonzalo would be unjustly enriched if allowed to retain the retention fee, having already received payment for the project while refusing to compensate Tarnate for the use of his equipment, labor, and materials. He posited that the exception to the in pari delicto doctrine should apply to prevent this unjust result.
• Performance of Obligations: Respondent maintained that he had fully complied with his obligations under the subcontract and deed of assignment by providing the necessary equipment, labor, and materials for the project, and that Gonzalo's unilateral revocation of the assignment was wrongful.

• Application of In Pari Delicto: Whether the doctrine of in pari delicto bars Tarnate from recovering the retention fee despite both parties having entered into an illegal subcontract prohibited by law.
• Validity of the Deed of Assignment: Whether the deed of assignment is void as a direct result of the illegal subcontract.
• Exception to In Pari Delicto: Whether the exception to the doctrine of in pari delicto applies to prevent unjust enrichment in this case.

• Equal Guilt: Both parties were in pari delicto. Tarnate was not less guilty than Gonzalo despite the CA's finding to the contrary. Tarnate, a businessman who represented himself as financially and organizationally sound, voluntarily entered into the agreements and admitted he did not participate in the bidding because he knew he was not authorized to contract with the DPWH. He was presumed aware of the illegality of the agreements.
• Void Contracts: The subcontract was illegal for violation of Section 6 of Presidential Decree No. 1594, which prohibits assignment or subcontracting without DPWH approval. Consequently, the deed of assignment, being a direct result of the illegal subcontract, was also void and inexistent under Articles 1409(1) and 1422 of the Civil Code.
• Exception to In Pari Delicto: The rigid application of the doctrine of in pari delicto is not absolute. An exception arises when its application contravenes well-established public policy, particularly the prevention of unjust enrichment under Article 22 of the Civil Code. Gonzalo would be unjustly enriched if permitted to retain the 10% retention fee representing compensation for Tarnate's equipment, labor, and materials, while Tarnate would bear the loss. The retention of this benefit by Gonzalo against the fundamental principles of justice, equity, and good conscience mandates the application of the exception.
• Damages Under Void Contract: No moral damages, attorney's fees, or litigation expenses may be recovered under a void contract, which produces no juridical tie between the parties. The lower courts failed to provide sufficient factual and legal justifications for these awards.
• Legal Interest: To ensure full reparation and prevent unjust enrichment, legal interest of 6% per annum is imposed on the principal amount of ₱233,526.13 from September 13, 1999, the date of judicial demand.

• In Pari Delicto — The doctrine holds that parties who are equally guilty of entering into an illegal contract cannot recover from one another, and no affirmative relief of any kind will be given to one against the other. No action arises in equity or at law from an illegal contract, and no suit may be maintained for specific performance or recovery of property or money agreed to be paid.
• Exception to In Pari Delicto: Public Policy Against Unjust Enrichment — The doctrine does not apply where its rigid application would contravene well-established public policy, particularly the principle against unjust enrichment under Article 22 of the Civil Code. When a person unjustly retains a benefit at the loss of another, or retains money or property of another against the fundamental principles of justice, equity, and good conscience, recovery is permitted notwithstanding the illegality of the contract.
• Void Contracts Cannot Produce Valid Contracts — Pursuant to Articles 1409(1) and 1422 of the Civil Code, a contract whose cause, object, or purpose is contrary to law is void and inexistent, and a contract which is the direct result of a previous illegal contract is also void and inexistent.

• "The doctrine of in pari delicto which stipulates that the guilty parties to an illegal contract are not entitled to any relief, cannot prevent a recovery if doing so violates the public policy against unjust enrichment." — This encapsulates the ratio decidendi of the case, establishing that public policy against unjust enrichment trumps the rigid application of the in pari delicto doctrine.
• "Article 22 is part of the chapter of the Civil Code on Human Relations, the provisions of which were formulated as basic principles to be observed for the rightful relationship between human beings and for the stability of the social order; designed to indicate certain norms that spring from the fountain of good conscience; guides for human conduct that should run as golden threads through society to the end that law may approach its supreme ideal which is the sway and dominance of justice." — This emphasizes the foundational importance of the prohibition against unjust enrichment in the Philippine legal system.
• "No damages may be recovered under a void contract, which, being nonexistent, produces no juridical tie between the parties involved." — This clarifies the limitation on remedies available under illegal contracts.

• Pajuyo v. Court of Appeals, G.R. No. 146364, June 3, 2004, 430 SCRA 492 — Cited for the proposition that the application of the doctrine of in pari delicto is not always rigid and that an exception arises when its application contravenes well-established public policy.
• Hulst v. PR Builders, Inc., G.R. No. 156364, September 3, 2007, 532 SCRA 74 — Cited for the definition of unjust enrichment and the rule that no damages may be recovered under a void contract.
• Rellosa v. Gaw Chee Hun, 93 Phil. 827 (1953) — Cited for the definition and scope of the doctrine of in pari delicto.
• Nool v. Court of Appeals, G.R. No. 116635, July 24, 1997, 276 SCRA 149 — Cited for the principle that a contract whose cause, object or purpose is contrary to law is void or inexistent.

• Section 6, Presidential Decree No. 1594 — Prohibits the contractor from assigning, transferring, or subcontracting any contract with the DPWH without approval of the Minister (now Secretary) of Public Works. Violation renders the subcontract illegal.
• Article 1409(1), Civil Code — Declares that a contract whose cause, object or purpose is contrary to law is void and inexistent from the beginning.
• Article 1422, Civil Code — Provides that a contract which is the direct result of a previous illegal contract is also void and inexistent.
• Article 1412(1), Civil Code — States that the guilty parties to an illegal contract cannot recover from one another and are not entitled to affirmative relief because they are in pari delicto.
• Article 22, Civil Code — Mandates that every person who acquires or comes into possession of something at the expense of another without just or legal ground shall return the same, embodying the principle against unjust enrichment.
