Spouses Reynaldo Alcaraz v. Pedro M. Tangga-An

Summary

This unlawful detainer case arose when lessees Alcaraz spouses stopped paying rent, claiming their lease with Virginia Tangga-an was automatically cancelled when her son Virgilio acquired the lot from NHA. The Supreme Court affirmed all lower courts' rulings for ejectment, holding that lot ownership does not automatically confer building ownership, and that buildings are distinct real properties from the land. The Court applied estoppel principles, finding petitioners could not claim contract cancellation after recognizing its validity for two years. The decision emphasized that ejectment cases focus on material possession, ownership issues are resolved only provisionally, and extrajudicial contract rescission requires express stipulation. The case demonstrates the separation between land and building ownership, contractual estoppel principles, and procedural requirements in unlawful detainer actions under Philippine civil and remedial law.
