G.R. No. L-6558, November 24, 1911
FEDERICO MARTINEZ, plaintiff-appellee, vs. CASIMIRO DIZA, ET AL., defendants-appellants.

FACTS

Federico Martinez filed an action to perpetually enjoin the defendants (primarily Cornelio Pasis and Dionisio Pasis) from constructing a dam across a small stream (zanja) in Vintar, Ilocos Norte, and from interfering with the flow of its water. Martinez claimed exclusive right to use the water for irrigation since 1884, based on uninterrupted use, and cited a prior 1904 judgment against Venancio Duque and Casimiro Diza (unrelated to the Pasises) that enjoined similar interference. The defendants asserted that they and their ancestors had used the water from time immemorial to irrigate their rice lands, which are located along the stream above Martinez’s property. Both parties agreed the stream originates from springs and that there is insufficient water to irrigate both parties’ lands simultaneously. The trial court ruled in favor of Martinez, granting the injunction.

ISSUE

Whether the defendants have a right to use the water from the stream for irrigating their lands, thereby justifying the reversal of the injunction granted by the trial court.

RULING

The Supreme Court REVERSED the trial court’s judgment and DISMISSED the complaint. The Court held that the defendants, Cornelio Pasis and Dionisio Pasis, were not bound by the 1904 judgment against Duque and Diza, as they were not parties to that case and did not derive their rights from those defendants. On the merits, the Court found the testimony conflicting but gave greater weight to the defendants’ evidence, considering key circumstances: (1) the defendants’ rice lands, situated along the stream above Martinez’s property, have been cultivated for many years and depend on the stream for irrigation; (2) Martinez has an alternative water source from another zanja that joins the stream below the defendants’ lands, whereas the defendants have no other water supply. The trial court erred in relying on the prior judgment and in not adequately considering these circumstances. Thus, the defendants rightfully used the water, and the injunction was improper.
