Final Decisions Stand: The Immutability of NLRC Rulings in Illegal Dismissal Cases

Once a decision of the National Labor Relations Commission (NLRC) becomes final and executory, it may no longer be changed or amended. This principle of immutability of judgment is a cornerstone of our legal system, ensuring that litigation comes to a definite end. In C-E Construction Corporation v. NLRC (G.R. No. 145930, August 19, 2003), the Supreme Court reaffirmed this rule in the context of an illegal dismissal case, clarifying the limits of a labor arbiter's power to modify a final judgment and the scope of an illegally dismissed employee's right to back wages.

The Facts of the Case

Gilbert Sumcad filed a complaint for illegal dismissal against C-E Construction Corporation in 1992, claiming he was a regular employee dismissed without cause. The company countered that he was a project employee whose services ended upon project completion.

The Labor Arbiter ruled in Sumcad's favor, ordering his reinstatement and payment of back wages and other benefits. On appeal, the NLRC affirmed that Sumcad was a regular employee but modified the award, ordering payment of back wages for one year. This NLRC decision became final and executory on December 8, 1994.

When Sumcad moved for execution, the case was re-raffled to a new Labor Arbiter. The company then requested a hearing to present evidence of Sumcad's earnings from other employment during the litigation period, hoping to reduce the back wages owed. The Labor Arbiter denied this request and instead issued an order directing reinstatement and payment of back wages, including "additional back wages." The NLRC later deleted this additional award.

The Court of Appeals voided these subsequent orders, ruling that the labor agencies could not alter rulings that had already become final and executory. The appellate court ordered execution of the original 1994 NLRC decision.

The Sole Issue: Can a Final and Executory Decision Be Modified?

The Supreme Court framed the issue simply: whether the NLRC's final and executory decision may still be modified. The answer was a firm no.

The Court held that the Labor Arbiter had no authority to alter the April 20, 1994 NLRC decision, which had long become final and executory. The arbiter's proper role at that stage was limited to issuing a writ of execution, not to revisiting the merits of the case or adding new awards. When the Labor Arbiter awarded "additional back wages," he exceeded his jurisdiction.

The Rule on Immutability of Judgments

The Court reiterated the settled rule: except for correction of clerical errors, final and executory judgments can neither be amended nor altered, even if the purpose is to correct erroneous conclusions of fact or of law. A party may not be allowed to present new evidence to show that a final judgment is erroneous.

The Court acknowledged a narrow exception: an appellate court may modify a final judgment when supervening events render execution unjust or inequitable. However, this exception does not apply when the basis for modification is evidence that existed before but was not presented during the hearing on the merits, despite ample opportunity to do so.

Full Back Wages Under Republic Act No. 6715

The company also sought to present evidence of Sumcad's earnings elsewhere to reduce the back wages award. The Court rejected this, citing Bustamante v. NLRC and Republic Act No. 6715, which amended Article 279 of the Labor Code.

Under the amended law, an illegally dismissed employee is entitled to full back wages, inclusive of allowances and other benefits, or their monetary equivalent, without any diminution or reduction by earnings derived elsewhere during the period of illegal dismissal. This marked a shift from earlier rules that either limited back wages to three years or allowed deductions for income earned from other employment.

The Court also noted that the company failed to file termination reports with the public employment office after each project, as required by Policy Instruction No. 20. This failure supported the finding that Sumcad was a regular employee, not a project employee. As the Court of Appeals aptly observed, the cessation of construction activities at the end of each project is a foreseeable suspension of work, not a severance of employment relations.

Practical Takeaways

• Finality matters. Once an NLRC decision becomes final and executory, it can no longer be changed, amended, or reopened, except for clerical corrections. This applies even if the decision contains alleged errors of fact or law.
• Labor arbiters enforce, not revise. After a judgment becomes final, the Labor Arbiter's role is limited to issuing a writ of execution. He or she cannot add new awards or reduce existing ones.
• Full back wages are the rule. Under Republic Act No. 6715, an illegally dismissed regular employee is entitled to full back wages without deduction for earnings from other employment during the period of dismissal.
• Present all evidence at trial. A party cannot use the execution stage to present evidence that was available, but not offered, during the hearing on the merits. Litigants must exhaust their evidence at the proper time.
• Project employee status requires compliance. Employers claiming project employee status must comply with reporting requirements under Policy Instruction No. 20; failure to do so may result in a finding of regular employment.
