Romualdo Osorio v. Pedro Cortez

Summary

This landmark case establishes crucial principles regarding sheriff liability in execution sales and property rights protection. Romualdo Osorio purchased land under pacto de retro from Salvador Rosales in 1903, but when Rosales faced a judgment from Pedro Cortez, the sheriff attached and sold the same land despite written notice from Osorio claiming ownership. The Supreme Court affirmed that execution sales of third-party property are void and that sheriffs are liable as trespassers when they sell property not belonging to the judgment debtor, regardless of good faith or writ authority. The decision emphasizes that execution writs only authorize sale of judgment debtor's property and that officers must determine ownership at their peril. This case protects property owners from wrongful deprivation through judicial process and establishes that due process requires sheriffs to respect third-party ownership claims supported by proper notice.
