Finality of Judgments: Understanding Immutability and Exceptions in Philippine Law

The doctrine of finality of judgments is a cornerstone of the Philippine legal system. It ensures that once a judgment becomes final and executory, it is immutable and can no longer be modified, even if the modification is meant to correct an erroneous conclusion of fact or law. This principle, rooted in public policy, guarantees stability and certainty in judicial proceedings. However, like all rules, it has exceptions.

In a recent case, Ondevilla v. Colegio de San Juan de Letran (Laguna), G.R. No. 278615 (June 29, 2026), the Supreme Court had the opportunity to revisit this doctrine in the context of a labor dispute. The case involved a long-serving employee who claimed he was illegally dismissed, and it raised important questions about the finality of labor tribunal rulings and the proper reckoning of retirement.

The Facts of the Case

Rodolfo C. Ondevilla was hired by Colegio de San Juan de Letran (CSJL) in Laguna in 2004 as Comptroller. His appointment was renewed, and in 2006, he was promoted to Assistant Vice President (AVP) for Finance and Controller. His appointment as AVP was renewed every three years until it expired on June 30, 2018.

When a new management took over in June 2018, a new organizational structure was implemented. Ondevilla was appointed as Controller for a fixed period, a position he considered a demotion that substantially reduced his salaries and benefits. CSJL, however, maintained that Ondevilla was a consultant and not a regular employee.

In November 2019, Ondevilla filed a complaint for illegal dismissal. The Labor Arbiter (LA) ruled in his favor, finding that he was a regular employee and was constructively dismissed. The National Labor Relations Commission (NLRC) affirmed this finding but modified the award, later ruling that Ondevilla was considered retired on August 29, 2019, his 60th birthday.

On appeal, the Court of Appeals (CA) held that Ondevilla was illegally dismissed on August 29, 2019, and that he had opted to retire on July 31, 2020. The CA awarded him backwages and retirement pay but did not grant separation pay.

The Issue: Finality of the NLRC Ruling

Before the Supreme Court, one of the key issues was whether the CA erred in re-litigating the issue of Ondevilla's employment status. The CA had noted that the NLRC's finding that Ondevilla was a regular employee had already attained finality and could no longer be re-litigated.

The Supreme Court affirmed this point. Once a judgment becomes final, it is binding on all parties and cannot be subject to further review or modification. This is the essence of the doctrine of immutability of judgments. The Court emphasized that in labor cases, while procedural rules are applied liberally, the principle of finality remains a fundamental safeguard.

The Ruling on Retirement and Illegal Dismissal

The Supreme Court also addressed the issue of Ondevilla's retirement. The CA had ruled that Ondevilla elected to retire on July 31, 2020, based on a letter he wrote. The Court disagreed.

Under Article 302 (formerly Article 287) of the Labor Code, as amended by Republic Act No. 7641, an employee may retire upon reaching age 60, but the compulsory retirement age is 65. The Court held that an employee who did not expressly agree to an early retirement cannot be retired before reaching age 65. Acceptance of an early retirement option must be explicit, voluntary, free, and uncompelled.

The Court found that Ondevilla's letter was merely a response to CSJL's demand for payment of a cash advance, not an express notice of his intention to retire. Since there was no bilateral agreement on early retirement, the Court ruled that Ondevilla was illegally dismissed on August 29, 2019, and was entitled to full backwages until his compulsory retirement age of 65 on August 29, 2024.

Separation Pay and Retirement Benefits

The Court also clarified that when reinstatement is no longer viable—such as when the employee has reached the compulsory retirement age—separation pay should be awarded in lieu of reinstatement. This is in addition to backwages.

The Court distinguished between two cases: Sampana v. The Maritime Training Center of the Philippines (2024) and Laya, Jr. v. Philippine Veterans Bank (2018). While Sampana did not award separation pay, Laya did. The Court held that Laya, being an en banc decision, prevails over Sampana, which was rendered by a division. Under Article VIII of the 1987 Constitution, a doctrine laid down by the Court en banc may only be modified or reversed by the Court sitting en banc.

Accordingly, the Court ordered the payment of separation pay, full backwages, retirement benefits under Article 302 of the Labor Code, and attorney's fees.

Practical Takeaways

• Finality of judgments is a strict rule. Once a decision becomes final and executory, it can no longer be modified, even if the modification would correct an error. This ensures stability in the legal system.
• Early retirement requires explicit consent. An employee cannot be retired before age 65 unless there is a clear, voluntary, and uncompelled agreement to an earlier retirement age.
• Reinstatement may be replaced by separation pay. If reinstatement is no longer possible—for example, because the employee has reached retirement age—separation pay should be awarded in addition to backwages.
• En banc decisions prevail over division rulings. When a doctrine is laid down by the Supreme Court en banc, it can only be modified or reversed by the Court sitting en banc.
• New issues cannot be raised on appeal. Parties are bound by the theories they adopt before the lower courts and cannot raise new issues for the first time on appeal.
