G.R. No. L-35059 February 27, 1973
ANTONIO T. TIONGSON, petitioner, vs. THE HONORABLE COURT OF APPEALS, PASCUAL ARNOBIT, ET AL., respondents.

FACTS

Petitioner Antonio Tiongson, owner of Green Valley Farm, filed an ejectment suit (CAR Case No. 1605-P-67) against his tenants, the private respondents. This case culminated in a judgment by compromise dated April 8, 1968, which was later amended on May 22, 1968, fixing the terms of their share tenancy relationship. Subsequently, on October 28, 1968, Tiongson filed a new ejectment action (CAR Case 1743-P-68) against the same tenants. The new complaint alleged that the tenants violated the compromise judgment by refusing to use certified fertilizers and a tractor offered by the landowner, both being proven farm practices, thereby causing him damage.
In their answer, the tenants raised the defense of res judicata, arguing the prior judgment barred the new suit. They counterclaimed that it was Tiongson who violated the terms by failing to furnish the inputs, and they sought conversion of their tenancy to leasehold and damages. The Court of Agrarian Relations ruled in favor of Tiongson, ordering the tenants’ ejectment. On appeal, the Court of Appeals reversed, dismissing the complaint on the ground of res judicata. It held that the remedy for alleged violations of the compromise judgment was not a new ejectment suit but a motion for execution in the original case (CAR Case No. 1605-P-67) to enforce its terms.

ISSUE

Whether the Court of Appeals erred in dismissing the second ejectment complaint on the ground of res judicata.

RULING

Yes, the Supreme Court reversed the Court of Appeals. The legal logic is that the principle of res judicata requires, among other elements, identity of causes of action. The Court held that the causes of action in the two cases were not identical. The first case (CAR Case No. 1605-P-67) was for ejectment based on grounds existing prior to the compromise agreement. Its resolution via a judgment by compromise settled those pre-existing disputes and established the governing terms for the tenancy relationship. The second case (CAR Case No. 1743-P-68) was based on new, distinct grounds—alleged violations of the very terms of that compromise judgment which occurred after its rendition. A cause of action arising from the breach of a compromise agreement is separate from the cause of action that led to the agreement itself.
Therefore, the second action was not barred, as it addressed subsequent breaches of the judicially approved compromise. The Court emphasized that to rule otherwise would unjustly tie a party’s hands from seeking redress for future violations of a court order. The proper remedy for such violations can indeed be either a motion for execution in the original case or a separate action for breach, depending on the circumstances and the relief sought. The case was remanded to the Court of Appeals for a decision on the merits of the second ejectment complaint. The Supreme Court also directed the immediate reinstatement of the tenants pending final resolution, as their dispossession was not yet authorized by a final and executory judgment.
