Greater Metropolitan Manila Solid Waste Management Committee vs. Jancom Environmental Corporation

A writ of execution must conform substantially to the judgment it seeks to enforce and may not vary its terms or go beyond them. Execution that is not in harmony with the judgment, such as ordering the enforcement of a contract expressly declared ineffective pending presidential approval or directing the submission of an unsigned draft amended agreement, is fatally defective.

Presidential Memorandum Order No. 202 created an Executive Committee to develop waste-to-energy projects under a Build-Operate-Transfer (BOT) scheme for waste disposal sites in Rizal and Cavite. Jancom International Development Projects Pty. Limited of Australia, after partnering with Asea Brown Boveri to form JANCOM Environmental Corporation, was declared the sole complying bidder for the San Mateo Waste Disposal Site. A BOT contract was executed on December 19, 1997, between the Republic of the Philippines and JANCOM. The contract required presidential approval for its effectivity. Following the closure of the San Mateo landfill by the Estrada administration due to public clamor, the Greater Metropolitan Manila Solid Waste Management Committee (GMMSWMC) adopted a resolution not to pursue the contract, citing the Clean Air Act of 1999, the non-availability of the site, and costly tipping fees.

• BOT Contract and Effectivity Clause: On December 19, 1997, the Republic of the Philippines and JANCOM executed a BOT contract for the San Mateo Waste Disposal Site. Article 19 of the contract expressly provided that it "shall become effective upon approval by the President of the Republic of Philippines." The contract was endorsed to then incoming President Estrada, who subsequently ordered the closure of the San Mateo landfill.
• GMMSWMC Resolution: Citing the Clean Air Act of 1999, the non-availability of the site, and costly tipping fees, the GMMSWMC adopted a resolution not to pursue the contract with JANCOM and called for new bids.
• Prior Supreme Court Ruling: In G.R. No. 147465, the Supreme Court declared the GMMSWMC resolution illegal and void, affirming the contract as valid and perfected. However, the Court explicitly ruled that the contract was "still ineffective or unimplementable until and unless it is approved by the President."
• Draft Amended Agreement: Following the Supreme Court ruling, JANCOM and the MMDA purportedly entered into negotiations to modify certain provisions, resulting in a draft Amended Agreement dated June 2002. The draft remained unsigned by the parties.
• Omnibus Motion and Alias Writ: Respondents filed an Omnibus Motion before the RTC seeking an alias writ of execution to enforce the prior judgment. The RTC granted the motion on June 11, 2003, issuing an alias writ that nullified other waste management contracts entered into by the MMDA and directed the MMDA to submit the Amended Agreement for presidential approval and to comply with Article 18 of the contract.
• Presidential Referral: During the pendency of the Omnibus Motion, MMDA Chairman Fernando had already forwarded the original contract to the Office of the President on November 3, 2002, accompanied by MMDA Resolution No. 02-18 recommending its disapproval.

• Ineffectivity of the Contract: Petitioners argued that because the contract remains unsigned by the President, it is ineffective and unimplementable; thus, execution proceedings ran afoul of the Supreme Court's decision in G.R. No. 147465.
• Scope of the Contract: Petitioners maintained that the contract covers only 3,000 tons of garbage per day, whereas Metro Manila generates at least 6,000 tons, justifying the MMDA's bidding out of the remaining capacity to other entities.
• Amended Agreement as Mere Draft: Petitioners argued that the Amended Agreement is a mere draft or proposal submitted by JANCOM, unsigned by the parties, and lacking any meeting of minds. Moreover, the MMDA lacked authority to conclude an amended agreement without express authorization, as the original contract was with the Republic of the Philippines.
• Reciprocal Compliance: Petitioners asserted that respondents should also be directed to perform their commitments under Article 18 of the contract.

• Right to Execution: Respondents countered that the trial court's decision had attained finality, and the prevailing party is entitled to a writ of execution as a matter of right, with issuance being the trial court's ministerial duty.
• Good Faith Compliance: Respondents argued that the contract's unimplementability without the President's signature does not excuse petitioners' failure to comply with their undertakings under Article 18 of the contract.
• Amended Agreement: Respondents contended that submitting the Amended Agreement to the President would break the impasse between the parties and address the garbage problem, asserting that the Amended Agreement did not veer away from the original contract and was likely negotiated with the former MMDA administration.

• Validity of Alias Writ of Execution: Whether the alias writ of execution varied the terms of the Supreme Court's prior judgment in G.R. No. 147465.
• Perfection of the Amended Agreement: Whether the trial court could order the submission of an unsigned draft Amended Agreement to the President.
• Due Date of Contractual Obligations: Whether respondents can be compelled to comply with their obligations under Article 18 of the contract.
• Authority of Counsel: Whether Atty. Molina possessed the authority to file the Omnibus Motion despite the objection of Jancom International.

• Validity of Alias Writ of Execution: The alias writ of execution was declared null and void for varying the judgment it sought to enforce. The Supreme Court's prior ruling explicitly held that the contract, while perfected, was ineffective and unimplementable without presidential approval. By ordering the enforcement of the contract, the trial court varied the tenor of the judgment, went against essential portions thereof, and exceeded its terms. A lower court is bound by the decree of a superior court as the law of the case and cannot vary or examine it for any purpose other than execution.
• Perfection of the Amended Agreement: The trial court order directing the submission of the Amended Agreement was defective in substance. The Amended Agreement was unsigned by the parties and was merely a draft document containing JANCOM's proposals. Because the contract is consensual, perfection requires the conformity of the parties through acceptance of an offer. Where there is merely an offer without acceptance, there is no consent and the contract does not come into existence. The original contract itself (Article 17.6) provided that it may not be amended except by a written contract signed by the parties.
• Due Date of Contractual Obligations: Respondents could not be directed to comply with their Article 18 obligations because the condition for their performance had not yet arrived. Article 18.2.1 expressly stated that the BOT Company undertakes to provide the required proofs and security "within 2 months from execution of this Contract as an effective document." Because the President had not yet signed the contract, it had not become an effective document, and the two-month period had not commenced.
• Authority of Counsel: The argument against Atty. Molina's authority was rejected. Representation continues until the court dispenses with the services of counsel pursuant to Section 26, Rule 138 of the Rules of Court. Because there was no valid substitution of counsel complying with the essential requisites—written request, written consent of client and counsel, or proof of notice—Atty. Molina continued to enjoy the presumption of authority to file the Omnibus Motion.

• Writ of execution must conform to the judgment — A writ of execution must conform to the judgment which is to be executed, substantially to every essential particular thereof. It may not vary the terms of the judgment it seeks to enforce, nor go beyond its terms. Where the execution is not in harmony with the judgment which gives it life and exceeds it, it has no validity. The Court applied this doctrine to nullify the alias writ, which effectively ordered the enforcement of a contract expressly declared ineffective pending presidential approval, thereby varying the Supreme Court's prior judgment.
• Perfection of contracts requires consent — Being consensual, a contract is perfected by mere consent, which is the conformity of the parties to the terms of the contract and the concurrence of their minds on the object and the cause. Where there is merely an offer by one party without acceptance by the other, there is no consent and the contract does not come into existence. The Court applied this principle to hold that the unsigned draft Amended Agreement was a mere unaccepted offer lacking the consent necessary to bind the parties.
• Substitution of counsel — No substitution of counsel of record is allowed unless the following essential requisites concur: (1) a written request for substitution; (2) filed with the written consent of the client; (3) with the written consent of the attorney to be substituted; and (4) in case the consent of the attorney to be substituted cannot be obtained, at least proof of notice that the motion for substitution was served on him in the manner prescribed by the Rules. The Court applied this doctrine to uphold the authority of Atty. Molina, noting the absence of a valid substitution of counsel.

• "That a writ of execution must conform to the judgment which is to be executed, substantially to every essential particular thereof, it is settled. It may not thus vary the terms of the judgment it seeks to enforce, nor go beyond its terms. Where the execution is not in harmony with the judgment which gives it life and exceeds it, it has no validity."
• "While there was an initial offer made, there was no acceptance. ... At any time prior to the perfection of a contract, unaccepted offers and proposals remain as such and cannot be considered as binding commitments."

• Metropolitan Manila Development Authority v. Jancom Environmental Corporation, 425 Phil. 961 (2002) — Controlling precedent. The Court reiterated its prior holding that the BOT contract was valid and perfected, but ineffective and unimplementable until and unless approved by the President.
• Reburiano v. Court of Appeals, 361 Phil. 294 (1999) — Cited for the proposition that errors in the course of execution proceedings prejudicial to a party's rights may be corrected by a superior court, specifically where the writ of execution varies the judgment.
• Luxuria Homes, Inc. v. Court of Appeals, 361 Phil. 989 (1999) — Followed. The Court relied on this case to establish that unsigned drafts of a proposed contract are mere unaccepted offers and cannot be considered binding commitments where the parties could not agree on the stipulations.

• Rule 39, Section 1, Rules of Court — Governs execution upon judgments or final orders. Cited to establish that execution issues as a matter of right upon a final judgment, but subject to exceptions where the writ varies the judgment.
• Rule 138, Section 26, Rules of Court — Governs the substitution of counsel. Cited to establish the rule that representation continues until the court dispenses with the services of counsel, and the requisites for valid substitution must be met.
• Article 1315, Civil Code — Defines the binding force of contracts. Cited in the prior G.R. No. 147465 decision to emphasize that parties are bound not only to what has been expressly stipulated but also to all consequences in keeping with good faith, usage, and law.
• Article 1319, Civil Code — States that consent is an essential requisite of a contract. Applied to determine that the Amended Agreement lacked consent and was therefore not perfected.
• Article 19, BOT Contract — Provides that the contract shall become effective upon approval by the President. Applied to hold that the contract remains ineffective without presidential approval.
• Article 17.6, BOT Contract — Provides that the contract may not be amended except by a written contract signed by the parties. Applied to demonstrate that the unsigned Amended Agreement could not validly amend the original contract.
• Article 18.2.1, BOT Contract — Requires the BOT Company to provide proof of equity, financial commitment, and a security bond "within 2 months from execution of this Contract as an effective document." Applied to hold that respondents' period to comply had not yet commenced because the contract was not yet an effective document.
