Republic of the Philippines v. Leon Silim

Summary

This case involved a donation of land by spouses Leon Silim and Ildefonsa Mangubat to the Bureau of Public Schools with the condition that it be used exclusively for school purposes. When the donated land was later exchanged for a bigger lot to accommodate government school building requirements, and the original donors discovered construction of a private house on the donated property, they filed suit claiming revocation of donation. The Supreme Court upheld the validity of the donation and exchange, ruling that the donation was properly accepted and that exchanging the land for a bigger lot to better serve the school purpose did not violate the donation's conditions. The Court emphasized that since this was an onerous donation (imposing a burden on the donee to build a school), it should be governed by contract law principles favoring the greatest reciprocity of interests.
