Res Judicata and Illegal Dismissal: Requisites for Dismissal of Labor Disputes in the Philippines

In illegal dismissal cases, a worker who withdraws an earlier complaint may later file a new one. But can the employer block the second case by invoking res judicata? The Supreme Court, in S.L. Teves, Inc./Hacienda Nuestra Senora del Pilar v. Eran (G.R. No. 172890, April 30, 2008), clarified when the doctrine applies—and why it failed in this case.

The Facts of the Case

Casiano Eran worked as a laborer in a sugar plantation starting in 1978. He was paid P53.00 per day, working from 6:00 a.m. to 5:00 p.m., Monday to Saturday. His tasks included clearing fields, gathering, harvesting, and hauling sugar canes, all under the direct control and supervision of a "cabo" (field supervisor).

On November 22, 2001, Eran was told by the cabo that his services were terminated. He filed a complaint for illegal dismissal and monetary claims with the NLRC.

However, on March 18, 2002, Eran withdrew his first complaint after receiving P175.00 for four days of work. The Labor Arbiter issued an Order dismissing the case "with prejudice."

On September 2, 2002, Eran filed a second complaint for illegal dismissal, underpayment, separation pay, damages, and attorney's fees. The Labor Arbiter dismissed this second complaint based on res judicata, relying on the earlier dismissal order. The NLRC affirmed.

The Court of Appeals reversed, ruling that Eran was a regular employee who was illegally dismissed. The Supreme Court affirmed the Court of Appeals.

The Issue: When Does Res Judicata Apply?

The central question was whether the dismissal of Eran's first complaint barred his second one under the principle of res judicata.

The petitioners argued that the first dismissal order had become final and executory, barring the second complaint. They also claimed that Eran had admitted he was not really their employee.

The Court disagreed, explaining that for res judicata to apply, four requisites must concur:

1. The former judgment must be final.
2. The court that rendered it had jurisdiction over the subject matter and the parties.
3. It must be a judgment on the merits.
4. There must be identity of parties, subject matter, and causes of action between the first and second actions.

Why Res Judicata Did Not Apply

The critical point was the third requisite: the first dismissal had to be a judgment on the merits.

The Court found that the Labor Arbiter's Order dated March 18, 2002 was merely "perfunctory." It did not delve into the merits of the case. The Receipt showing Eran received P175.00 proved only that he was paid for work rendered—it did not prove that he voluntarily withdrew his complaint or that he admitted working without the employer's knowledge and consent.

Whether the withdrawal was voluntary, and whether Eran truly admitted he was not an employee, were factual questions. Under Rule 45 of the Rules of Court, the Supreme Court only reviews questions of law, not questions of fact. It is not a trier of facts.

Since the first dismissal was not shown to be a judgment on the merits, res judicata could not bar Eran's second complaint.

The Court's Ruling

The Supreme Court denied the petition and affirmed the Court of Appeals' ruling that Eran was a regular employee who was illegally dismissed. He was entitled to reinstatement and his monetary claims.

The Court also noted that the Court of Appeals' factual findings were in accord with the evidence on record.

Practical Takeaways

• Res judicata requires a judgment on the merits. A dismissal based on a technicality or a perfunctory order that does not decide the case's substance will not bar a subsequent complaint.
• A receipt for wages is not an admission. Paying a worker for days rendered does not prove that the worker voluntarily withdrew a complaint or admitted to being a non-employee.
• Withdrawal of a complaint must be voluntary. If the withdrawal is not clearly voluntary, it may not result in a dismissal "with prejudice" that bars future claims.
• The Supreme Court is not a trier of facts. In appeals by certiorari under Rule 45, only questions of law may be raised. Factual disputes must be resolved by lower tribunals.
• Regular employees are protected. Workers who have rendered years of service under the control and supervision of their employer are generally considered regular employees entitled to security of tenure.
