FACTS:

Spouses Ladrido were owners of a registered land.  Spouses Teh were also owners of a registered land.  The latter sold the land to Viajar.  During a relocation  survey,  it  was  found  out  that  the  land  was  being  occupied  by Ladrido.  It was found out also that the 2 parcels of land were separated by the river—one portion was being possessed by the defendant together with the old river bed.
 

HELD:

Registration  under  the  Torrens  system  doesn't  protect  the  riparian  owner against  the  dimunition  of  the  area  of  his  registered  land  through  gradual changes in the course of an adjoining stream.
