Philippine National Railways v. National Labor Relations Commission

Summary

This case involved the prescription of the right to execute a 16-year-old labor judgment. Rodolfo Caldo obtained a favorable CIR judgment in 1973 ordering his reinstatement and back wages. While PNR paid back wages and acknowledged the obligation in 1974, they failed to reinstate him. In 1986, Caldo sought execution, which the Labor Arbiter and NLRC allowed based on the theory that PNR's written acknowledgment indefinitely suspended prescription under Article 1155 of the Civil Code. The Supreme Court reversed, clarifying that written acknowledgment under Article 1155 merely interrupts and renews prescription rather than stopping it completely. Since the 10-year prescriptive period under Article 1144 had expired, and execution by motion was only available within 5 years under Rule 39, Caldo's attempt at execution was time-barred. The case establishes important precedent on the effects of acknowledgment on prescription periods and the procedural requirements for executing old judgments.
