Decision 40 G.R. No. 224469 the communal purpose and the instructions of petitioners' elders and the assurances of a non-governmental organization and the NCIP, are more likely than not necessarily connected to this pre- and post-colonial cultural practices and an integral part of its continuity to the present. The reason for this is that since time immemorial, probably this has been how the Mangyans, including petitioners herein, have been able to source the materials for their communal building activities. To further support their claim that they were justified in logging the dita tree, petitioners contend as well that even prior to the effectivity of the IPRA on March 30, 1998, the Iraya-Mangyans had already applied for a Certificate of Ancestral Domain Claim (CADC). 100 As of March 31, 2018, the NCIP data show that CADC No. R04-CADC-126 dated June 5, 1998 was issued to the Iraya-Mangyan IP and is pending conversion to a Certificate of Ancestral Domain Title (CADT). 101 Although the conversion of the CADC to a CADT is still pending, we take judicial notice that the nearly perfected claim covers the municipalities of Baco, San Teodoro, and Puerto Galera in Oriental Mindoro with a land area of 33,334 hectares. 102 A CADC is the State's formal recognition of an IP/ICCs' claim to a particular traditional territory which the IP/ICC has possessed and occupied, communally or individually, in accordance with its customs and traditions since time immemorial. 103 The issuance of a CADC involves a painstaking process of submitting documents and testimonies attesting to the possession or occupation of the area since time immemorial by such indigenous community in the concept of owners. 104 The fact that a certificate of title or f'.ADT has yet to be issued to the Iraya-Mangyan IPs does not diminish, much less, negate their communal ownership of the land in question. After all, a paper title is just proof of 100 Supra note 1. https://www.doe.gov.ph/sites/default/files/pdf/eicc/cadt-region04, (last accessed: January 22, 2020). 102 Section 1.
