Summary
This property dispute involved competing claims over a 52,528 sq.m. area created when the Jalaud River changed course in the 1970s. Petitioner Degayo claimed the area was an accretion to her inherited Lot No. 861, while respondents Magbanua family claimed it was an abandoned riverbed belonging to them as compensation for their Lot No. 7328 area now occupied by the river. The Supreme Court applied res judicata principles, specifically conclusiveness of judgment, finding that the ownership issue was definitively resolved in Civil Case No. 16047 where the RTC ruled in favor of respondents. Despite Degayo not being formally impleaded in the first case, the Court found sufficient identity of parties through community of interest with the tenants and noted Degayo had testified in that case on the same issues. The decision reinforced the finality of judgments and the doctrine's role in preventing relitigation of settled matters, ultimately denying Degayo's petition and affirming respondents' ownership of the disputed area as abandoned riverbed.
