G.R. No. L-45268 December 3, 1987
ISIDORO LIMQUIACO JR., petitioner, vs. HON. JOSE R. RAMOLETE, et al., respondents.

FACTS

Petitioner Isidoro Limquiaco Jr., a route salesman for Pepsi Cola Bottling Co., Inc., was dismissed in 1972. He filed an illegal dismissal and unfair labor practice case (NLRC Case No. 006) with the National Labor Relations Commission (NLRC). The NLRC ruled in his favor, ordering reinstatement with back wages. Pepsi appealed, but the NLRC en banc dismissed the appeal. To execute the judgment, the sheriff levied a Pepsi truck. Pepsi then filed a prohibition case (Civil Case No. 4411) in the Court of First Instance (CFI) of Misamis Oriental to stop the auction.
During the hearing for a preliminary injunction, the parties submitted a Compromise Agreement. Pepsi agreed to pay Limquiaco specific sums representing the NLRC award and other termination benefits. The agreement stated this total payment constituted full satisfaction of all claims arising from his employment. The CFI approved the agreement, and Limquiaco received payment.

ISSUE

Whether the petitioner can subsequently file a separate civil action for damages arising from the same illegal dismissal, after a compromise agreement had been approved by the court, fully settling all claims from his employment.

RULING

The Supreme Court denied the petition, upholding the dismissal of the separate civil action for damages. The Court’s legal logic is anchored on the principle of avoiding split jurisdiction and respecting the finality of settlements within the proper forum. The core dispute originated from a labor matter—illegal dismissal and unfair labor practice—which was within the exclusive original jurisdiction of the labor tribunal (the ad hoc NLRC under Presidential Decree No. 21). All claims for damages intrinsically linked to or arising from that labor dispute, including those stemming from the allegedly illegal and malicious acts of dismissal, should have been asserted and adjudicated within that same labor case. Permitting a separate civil suit in the regular courts would sanction an improper splitting of a single cause of action, leading to potential conflicting rulings and undermining orderly justice administration.
The Court further clarified that, at the time, the NLRC possessed the jurisdiction to award damages in labor cases. Since the labor case had reached finality through a compromise judgment approved by the CFI (in its appellate or supervisory capacity over the execution), which expressly extinguished all claims, the petitioner was barred from relitigating the matter under a different guise in the regular courts. The compromise agreement constituted a final settlement, precluding any further action on claims emanating from the employment relationship.
