Besides, when Congress enacted the Indigenous Peoples’ Rights Act (IPRA) or Republic Act 83719 in 1997, it provided in Section 56 that "property rights within the ancestral domains already existing and/or vested" upon its effectivity "shall be recognized and respected." In this case, ownership over the subject lands had been vested in CMU as early as 1958. Consequently, transferring the lands in 2003 to the indigenous peoples around the area is not in accord with the IPRA.
