Marcopper Mining Corp. vs. Briones

A labor arbiter cannot substantially alter a final and executory judgment; an amendment materially affecting that judgment is void for lack of jurisdiction. Marcopper’s belated and inconsistent claim that Briones’s position had been abolished did not justify substituting separation pay for reinstatement or imposing a cutoff on her benefits.

Marcopper Mining Corporation was a domestic corporation employing Liwanag Paras Briones. Worldwide recession and a prolonged slump in metal prices caused successive financial losses, prompting the company to streamline operations according to economic standards set by its lending banks. Its two-stage retrenchment program offered voluntary early retirement, preferably to senior employees, with one month’s salary for every year of service, followed by compulsory retrenchment with separation pay of one-half month’s salary for every year of service.

Liwanag Paras Briones began working for Marcopper Mining Corporation on April 28, 1980 as a probationary warehouse clerk. She became a permanent employee on July 28, 1980 and was reclassified on July 1, 1981 as a Department Secretary assigned to the Warehouse Manager.

Briones did not apply for early retirement and was compulsorily retrenched on February 5, 1983. Dalisay Arenas, formerly secretary to the resident manager, took over her position after Arenas’s own position was abolished. Arenas had expressed willingness to retire under the company’s program, but Marcopper disapproved her application and instead retrenched Briones despite her protest. Briones refused the separation pay tendered by Marcopper and filed an illegal dismissal complaint on May 13, 1983.

After the reinstatement judgment became final on October 7, 1985, the NLRC issued a writ of execution on November 12, 1985. It required Briones’s actual reinstatement and payment of ₱53,732.25, representing backwages, allowances, and other monetary benefits from February 5, 1983 through October 31, 1985, without including benefits accruing after that date. Marcopper received the writ on December 9, 1985.

On December 12, 1985, Marcopper moved for recomputation, asserting that Briones’s former position had been abolished and that no vacancy existed in its pool of secretaries. It also claimed that she had obtained employment in the office of Assemblywoman Carmencita O. Reyes. Briones denied both assertions: she maintained that Zenaida Echinigue was occupying her position and that she had not worked for the assemblywoman. The Labor Arbiter stayed execution and allowed the parties to present evidence. Marcopper submitted a position paper and a personnel officer’s certification asserting that Briones’s position had been abolished during a second retrenchment in 1985; Briones did not submit a position paper.

The claimed abolition was placed in February 1985, but Marcopper raised it before the Labor Arbiter only in December 1985. Its earlier certiorari petition, filed on August 22, 1985, had effectively admitted that Briones’s position had not been abolished. The Labor Arbiter nevertheless accepted Marcopper’s evidence of abolition during execution proceedings. This differed from the factual basis of the original illegal dismissal judgment, which had found discriminatory treatment in Marcopper’s retention of Arenas while removing Briones.

• Supervening Events: Marcopper argued that a final judgment could be modified when later facts made execution impossible or unjust, and that the original tribunal could determine those facts and adjust execution accordingly.

• Impossibility of Reinstatement: Marcopper maintained that Briones’s position had been abolished, no vacancy existed among its secretaries, and no substantially equivalent position was available. It argued that separation pay should therefore replace reinstatement.

• Recomputation of Monetary Benefits: Marcopper sought reduction or adjustment of the monetary award because Briones had allegedly obtained employment in Assemblywoman Carmencita O. Reyes’s office. Its partial appeal also questioned the computation of backwages and separation pay.

• Grave Abuse of Discretion: Marcopper argued that the NLRC gravely abused its discretion by reversing the Labor Arbiter’s March 7, 1986 order and insisting on enforcement of the original judgment regardless of supervening circumstances.

• Immutability of the Judgment: Briones argued that substituting separation pay for reinstatement and imposing a cutoff on monetary benefits unlawfully amended a final judgment requiring reinstatement and benefits until actual reinstatement.

• Due Process: Briones maintained that the March 7, 1986 order was invalid to the extent that it altered her adjudged rights and deprived her of property without due process.

• Continued Existence of the Position: Briones disputed the alleged abolition, asserting that Zenaida Echinigue occupied her position. She also pointed out that Marcopper’s August 22, 1985 petition had effectively admitted the position’s continued existence despite the supposed February 1985 abolition.

• Alleged Outside Employment: Briones denied that she had been employed in Assemblywoman Carmencita O. Reyes’s office.

• Substantially Equivalent Position: The Office of the Solicitor General maintained that, even assuming abolition of the original position, Briones could be reinstated to a substantially equivalent position without loss of seniority rights.

• Finality of Judgment: Whether the Labor Arbiter could substantially amend the final and executory reinstatement judgment during execution proceedings.

• Claimed Supervening Abolition: Whether Marcopper established an abolition of Briones’s position that justified modification of the final judgment.

• Reinstatement and Backwages: Whether Briones remained entitled to reinstatement and what backwage relief should be enforced.

• Finality of Judgment: No. Once the judgment became final and executory, the Labor Arbiter retained jurisdiction to execute it but could not substantially alter its terms; amendments materially affecting it were void for lack of jurisdiction.

• Claimed Supervening Abolition: No. Marcopper’s delayed assertion of abolition contradicted its earlier representation that the position continued to exist, leading the SC to reject the alleged abolition as an afterthought intended to remove Briones.

• Reinstatement and Backwages: Briones must be reinstated to a substantially equivalent position without loss of seniority rights, privileges, and legally due benefits. Her backwages were limited to three years without qualification or deduction, with legal interest until full payment.

• Finality of Judgment: Before finality, a tribunal may alter, modify, or set aside its decision. After finality, amendments or corrections are confined to clerical errors or mistakes; a substantial alteration is beyond its jurisdiction. The SC relied on People vs. Villanueva, Maramba vs. Lozano, Samar vs. Montejo, Dela Cruz vs. Plaridel Surety & Insurance Co., Ocampo vs. Caluag, and Macantos vs. Guino in explaining these limits. The original judgment required reinstatement and payment of benefits until actual reinstatement. The March 7, 1986 order replaced reinstatement with separation pay and imposed a December 15, 1985 cutoff for backwages, allowances, and thirteenth-month pay. These changes affected substantive rights rather than clerical matters. The Labor Arbiter therefore lacked jurisdiction to make them, and the proceedings undertaken for that purpose were likewise void. The SC consequently found no need to address Marcopper’s other issues relating to those proceedings.

• Claimed Supervening Abolition: Marcopper invoked an exception based on circumstances allegedly making execution impossible or unjust, but the surrounding facts did not support its claim. Although the abolition supposedly occurred in February 1985, Marcopper disclosed it to the Labor Arbiter only in December 1985. More significantly, its August 22, 1985 petition had effectively admitted that Briones’s position had not been abolished, even though that petition was filed more than five months after the supposed abolition. The personnel certification did not overcome these inconsistencies. The SC concluded that the alleged abolition, if undertaken, was an afterthought connected with Marcopper’s determination to remove Briones.

• Reinstatement and Backwages: Briones’s dismissal had already been found discriminatory and illegal, and the SC’s dismissal of Marcopper’s earlier petition had sustained that finding. Her security of tenure could not be defeated through the subsequent scheme to remove her. Even assuming that her former position had been abolished, reinstatement to a substantially equivalent position remained available. The SC rejected Marcopper’s assertion that no such position existed, considering that it was one of the country’s top corporations. It required reinstatement without loss of seniority rights, privileges, and legally due benefits, while limiting backwages to three years without qualification or deduction and adding legal interest until full payment. The discussion specified computation from February 1, 1983; the dispositive order specified February 1, 1973.

• Immutability of Final Judgments — A final and executory judgment cannot be materially altered, even by the tribunal that rendered it; clerical errors or mistakes may be corrected. Replacing reinstatement with separation pay and imposing a cutoff on benefits substantially changed Briones’s adjudged rights.

• Jurisdiction After Finality — After a judgment becomes final, the originating tribunal retains authority to execute it but loses jurisdiction to make substantive amendments. An amendment substantially affecting the judgment, including proceedings conducted for that purpose, is void for lack of jurisdiction.

• Security of Tenure and Equivalent Reinstatement — The claimed abolition of an illegally dismissed employee’s former position did not defeat reinstatement where the SC rejected the employer’s assertion that no substantially equivalent position existed. Briones was entitled to reinstatement to such a position without loss of seniority rights, privileges, and legally due benefits.

• "A judgment which has become final and executory can no longer be amended or corrected by the court except for clerical errors or mistakes." — This states the governing limit on alterations after finality. The changes to reinstatement and monetary benefits were substantive.

• "Any amendment or alteration made which substantially affects the final and executory judgment is null and void for lack of jurisdiction, including the entire proceedings held for that purpose." — This explains why the Labor Arbiter’s revised award and the proceedings supporting it could not stand.

• People vs. Villanueva, 17 SCRA 272 (1966) — Cited for the authority to alter, modify, or set aside a decision before it becomes final.

• Maramba vs. Lozano, 20 SCRA 474 — Relied upon for the rule that a final and executory judgment may no longer be amended or corrected except for clerical errors or mistakes.

• Samar vs. Montejo, 9 SCRA 419 — Cited to support the prohibition against material or substantial alteration of a final judgment.

• Dela Cruz vs. Plaridel Surety & Insurance Co., 10 SCRA 727 — Cited with the authorities prohibiting substantial modification after finality.

• Ocampo vs. Caluag, 19 SCRA 971 — Cited to reinforce the immutability of a final and executory judgment.

• Macantos vs. Guino, 13 SCRA 685 (1965) — Relied upon for the rule that a trial tribunal or labor arbiter cannot change a decision of the SC that has become final and executory.
