Yusingco v. Busilak

Summary

This case involves the Heirs of Alfonso Yusingco seeking recovery of possession of three parcels of land in Surigao City from respondents who allegedly illegally occupied the properties. The petitioners had previously won reivindicatoria cases establishing their ownership. The MTCC and RTC ruled in favor of petitioners, but the CA reversed, holding that previous judgments were in personam and did not bind respondents who were not parties to earlier cases. The Supreme Court reversed the CA, ruling that respondents, being mere trespassers, are bound by the previous judgments declaring petitioners as lawful owners. The case clarifies the distinction between accion publiciana and accion reivindicatoria, and establishes that trespassers may be bound by in personam judgments even if not original parties, reinforcing property rights of judicially-declared owners against illegal occupants.
