FACTS:Subject land was 20 meters away from the shores of Laguna de Bay. It was owned by Benedicto del Rio. After his death, it was acquired by Santos del Rio. Private oppositors sought permission and obtained the same to construct duck houses. They violated agreement by consructing residential houses. Santos then sought to register the land which was opposed. The oppositors was able to obtain sales application on the land. The director of Lands alleged that since a portion of the land is submerged in water 4 to 5 months, then it forms part of the public domain.
HELD:According to the Law of Waters, the natural bed or basin of lakes, ponds, or pools is the covered by their waters when at their highest ordinary depth—regular, common, natural, which occurs almost or most of the time during the year.
Laguna de Bay is a lake and that part around it which becomes covered with water 4 to 5 months a year, not due to tidal action, but due to rains cannot be considered as part of the bed or basin of Laguna de Bay nor as a foreshore land. Property not being so, the land is registrable.
