The document discusses two court cases related to land registration and ownership. In the first case, Ramos vs Dir. of Lands, the court ruled that constructive possession of part of a land through a color of title document was sufficient to claim ownership over the entire tract. In the second case, Heirs of Amunategui vs Dir. of Forestry, the court considered whether a mangrove swamp area classified as a forest reserve could be privately owned, ultimately ruling that it remained public land without reclassification. Both cases addressed the issue of whether claimed private lands were actually part of forest reserves and public domains.
