G.R. No. L-13072 - Hacienda Luisita vs. National Labor Union

The National Labor Union initiated a proceeding against Hacienda Luisita (CIR Case No. 835-V) prior to February 10, 1954, with various demands regarding the employment conditions of its members.
On February 10, 1954, the parties entered into a compromise agreement, which was subsequently approved by the court on February 11, 1954, thereby giving the agreement the force of a judicial decision.

The agreement primarily addressed the nature of the work and the corresponding pay for employees designated as tractoristas and farmalistas.
Paragraph 3 of the agreement provided that Hacienda Luisita would maintain a six-day work week for these employees but was allowed to assign them to other types of work (with specific exclusions) if there was no work available connected with the operation and maintenance of tractors.
The agreement was binding on both parties for a minimum period of three years, as stipulated by the underlying legal provisions.

After the initial agreement, the National Labor Union was certified as the exclusive bargaining agent for Hacienda Luisita’s laborers and employees.
A new collective bargaining agreement (Annex "C") was entered into on December 18, 1956, which included provisions concerning the status of tractoristas and farmalistas, specifically:

Allowing retirement under terms similar to those for employees of the Taller and Almacen Departments.
Providing that if certain employees did not opt for retirement, Hacienda Luisita could, on February 11, 1957, exercise its purported right (based on Section 17 of Commonwealth Act No. 103) to terminate the effectiveness of the earlier award, thereby converting the remaining workers into regular milling season workers.
Stipulating that any legal dispute arising from this interpretation would be resolved through future litigation, with the binding effect of the court’s final decision.

A misunderstanding arose between Hacienda Luisita and the union concerning the timing and legal right to convert tractoristas and farmalistas into regular season or milling workers.
Rodolfo Garcia, representing the union, filed a motion for clarification before the Court of Industrial Relations, asserting that termination of the award should not occur before three years after the effectivity of the December 18, 1956 agreement.
Hacienda Luisita opposed the motion, maintaining its belief in its right to effect the conversion based on its interpretation of the February 11, 1954 compromise.

On August 26, 1957, the Court of Industrial Relations sustained the union’s contention by citing the principle that a contract may not be unilaterally altered by one party.
A subsequent motion to reconsider the Court’s order was denied on October 19, 1957, leading to the petition for a writ of certiorari contesting that decision.

Section 17 of Commonwealth Act No. 103 was cited, which establishes that an award or decision is effective for the period specified—in its absence of any specified duration, the effectiveness is limited to three years from the date of the award.
The court highlighted that while unilateral termination is generally not allowed, the statutory provision permits modification after the expiration of the three-year period.
The decision also referenced the case of Katipunan Labor Union vs. Caltex (Phils.) and the Court of Industrial Relations, establishing that a contract cannot be arbitrarily set aside by unilateral action.

The seasonal nature of work in sugar cane cultivation justifies the conversion of tractoristas and farmalistas into regular milling season workers upon the expiration of their contractual term.
Hacienda Luisita’s action was deemed reasonable given that the original compromise contemplated reassignment to other jobs only when tractor use was unavailable.
The subsequent bargaining agreement of December 18, 1956, explicitly provided for the classification and potential conversion of workers based on the operational and seasonal needs of the hacienda.

Hacienda Luisita petitioned for a writ of certiorari, seeking to reverse the Court of Industrial Relations’ resolution that limited its right to terminate the award before June 14, 1959.
The key contention was whether the three-year period fixed by law had already expired, thereby permitting the hacienda’s contemplated conversion of the affected workers.

Whether Hacienda Luisita had the legal right, under the terms of the approved compromise agreement and subsequent bargaining agreement, to unilaterally terminate or modify the award granted by the Court of Industrial Relations.
Whether the statutory period of effectiveness (three years as provided under Section 17 of Commonwealth Act No. 103) had expired, thereby authorizing Hacienda Luisita to convert tractoristas and farmalistas into regular milling season workers.
Whether the provision allowing unilateral termination or modification of the award by Hacienda Luisita violated the established principle that a contract may not be unilaterally altered by one party without mutual consent.
