G.R. No. L-21436 August 18, 1972
Republic of the Philippines (Represented by the Land Tenure Administration, substituted by the Land Authority), plaintiff and appellant, vs. Mariano F. Lichauco, et al., defendants. Jose M. Lichauco, Trinidad Gonzales, Francisco Castillo and Jose Castillo, defendants and appellants.

FACTS

The Republic, through the Land Tenure Administration, filed a complaint to expropriate the 1,352-hectare Hacienda El Porvenir in Pangasinan under Republic Act No. 1400 , citing agrarian conflicts. The defendants initially moved to dismiss, challenging the law’s constitutionality and claiming the property had been partitioned. However, the parties later entered into an “Agreement and Joint Motion,” wherein the defendant co-owners agreed to the expropriation of the hacienda, subject to their retention of specific, delineated portions totaling approximately 362.67 hectares. The agreement stipulated the survey of retained areas, waiver of the right to contest the expropriation of the remainder, and detailed terms for payment, including handling liens and a provision for currency revaluation.
The trial court approved this agreement and rendered a decision based on its terms. Dissatisfied with the just compensation fixed by the court, both the Republic and some defendants appealed. The Republic argued the valuation was excessive, while the appealing defendants contended it was insufficient, also raising issues about the validity of the agreement and the exclusion of certain lands from expropriation.

ISSUE

The primary issue was whether the “Agreement and Joint Motion” constituted a valid and binding compromise agreement that determined the rights of the parties, particularly regarding the area subject to expropriation and the framework for determining just compensation.

RULING

The Supreme Court affirmed the trial court’s decision, upholding the binding force of the Agreement. The Court ruled that the Agreement was a valid compromise, which under Article 2028 of the Civil Code has the effect of res judicata and is immediately executory upon approval by the court. The parties voluntarily entered into the Agreement to avoid protracted litigation, and its terms were clear. The Court emphasized that a compromise settles controversies definitively, and parties are bound by its stipulations.
Consequently, the defendants who signed the Agreement were estopped from later contesting the expropriation of the non-retained areas or claiming a right to retain more land. The Agreement expressly waived their right to contest and defined the retained portions. The Court also found the stipulated method for determining just compensation—based on the current market value at the time of payment, with a provision for currency revaluation—to be valid and binding as part of the compromise. The appeals challenging the compensation were dismissed, as the Agreement governed the obligations of both parties, and the trial court correctly implemented its terms.
