United CMC Textile Workers Union v. Valenzuela
REITERATIONFacts
1. The Antecedents: The petitioner, United CMC Textile Workers Union, filed a complaint against Central Textile Mills, Inc. (CTMI) for non-payment of the 1978 Christmas bonus as stipulated in their collective bargaining agreement (CBA). The CBA outlined a bonus schedule based on years of service. The Labor Arbiter ordered CTMI to pay P122,840.00 for the 1978 Christmas bonus. 2. Procedural History: CTMI appealed the Labor Arbiter's decision to the National Labor Relations Commission (NLRC), which affirmed the decision with a modification regarding the furnishing of computation lists. CTMI then filed a petition for certiorari with the Supreme Court (G.R. No. 58666), which was dismissed for lack of merit. A motion for reconsideration was also denied, and the dismissal became final and executory. Subsequently, CTMI appealed to the NLRC again, arguing that the Supreme Court's ruling in National Federation of Sugar Workers vs. Central Azucarera de la Carlota rendered the prior judgment moot. The Labor Arbiter, citing this, refused to issue a writ of execution. 3. The Petition: The United CMC Textile Workers Union filed this petition for mandamus, seeking to compel the respondent Labor Arbiter to issue a writ of execution for the final and executory judgment in G.R. No. 58666. The petitioner argues that a final and executory judgment is enforceable within five years and cannot be rendered moot by subsequent rulings, citing the doctrine of res judicata. They contend that the La Carlota ruling, even if it changed legal interpretation, cannot affect a judgment that has already become final. The petition also asserts that the CBA bonus was intended to be in addition to the 13th-month pay and that the deletion of the bonus provision in a later CBA did not waive the claim for the 1978 bonus.
Issue(s)
Whether the Labor Arbiter may be compelled by writ of mandamus to issue a writ of execution for a final and executory judgment. Whether a subsequent Supreme Court ruling can render a final and executory judgment moot and academic. Whether the doctrine of res judicata bars CTMI's appeal to the NLRC.
Ruling
The petition is GRANTED. Respondent Labor Arbiter Raymundo Valenzuela is ordered to issue the writ of execution in Case No. AB-62563-79 (NCR-LRD-6-740-79), G.R. No. 58666.
Ratio Decidendi
On the issue of compelling the Labor Arbiter to issue a writ of execution: The Court held that once a judgment becomes final and executory, it is the ministerial duty of the Labor Arbiter to issue the writ of execution. The petitioner was vested with a right to the satisfaction of the judgment upon its finality. The Court emphasized that a decision or resolution that has become final and executory is enforceable within five years, and without the writ of execution, the petitioner's affirmed rights would be rendered nugatory. On whether a subsequent ruling can render a final judgment moot and academic: The Court ruled that a subsequent ruling, even if it adopts a different legal principle, cannot render a final and executory judgment moot and academic. The principle of "the law of the case" dictates that once a judgment has become final, no additions can be made to it, and nothing can be done except its execution. To allow otherwise would lead to endless litigation and undermine the purpose of justice, which is to settle controversies with finality. The Court explicitly stated that the La Carlota Case ruling could not render the final decision in G.R. No. 58666 moot and academic. On the applicability of res judicata: The Court found that the appeal filed by CTMI with the NLRC was barred by the prior judgment in G.R. No. 58666 under the doctrine of res judicata. The requisites for res judicata were present: a final judgment on the merits rendered by a court with jurisdiction, and an identity of parties, subject matter, and cause of action between the first and second actions. Therefore, the appeal filed by CTMI was rendered moot and academic by the prior judgment.
Main Doctrine
A final and executory judgment can no longer be amended or modified, and subsequent rulings cannot render it moot and academic. The doctrine of res judicata bars appeals that violate this finality.
