G.R. No. 204759 - People's General Insurance Corp. vs. Guansing

The case involves a petition for review on certiorari filed by the Republic of the Philippines, represented by Dr. Rubina O. Cresencio and Marilyn V. Sta. Catalina, challenging lower court rulings.
The challenged decision arose from the dismissal by the Regional Trial Court (RTC) of Baguio City, Branch 6 in Civil Case No. 7200-R, which itself dismissed the Republic’s Complaint for reversion, annulment of documents, and cancellation of titles.

Private respondents, the Heirs of Ikang Paus (represented by Elias Paus), had filed a petition for the identification, delineation, and issuance of a Certificate of Ancestral Land Title (CALT) covering an ancestral land in Baguio City and adjacent areas in Tuba, Benguet.
The National Commission on Indigenous Peoples (NCIP) resolved the petition by issuing Resolution No. 060-2009, which declared the land as ancestral land and directed the issuance of two CALTs based on the submitted plan.
Consequently, an Original Certificate of Title (OCT No. 0-CALT-37) covering a 623,108-square meter lot in Baguio City was issued to the Heirs of Ikang Paus.

The Heirs of Mateo CariAo opposed the ancestral claim and the issuance of the CALT/CALT-derived OCT, seeking its cancellation via a separate motion and later through a petition-in-intervention.
On June 10, 2010, the Republic, through the Office of the Solicitor General, questioned the validity of OCT No. 0-CALT-37 and filed a suit for reversion, annulment of documents, and cancellation of title, attaching a request for a temporary restraining order and a preliminary injunction.
In its answer, the private respondents (Heirs of Ikang Paus) denied all material allegations and advanced special and affirmative defenses asserting that the RTC lacked jurisdiction over the subject matter since the CALT and the subsequent OCT arose from an NCIP resolution—a matter falling under the NCIP’s exclusive competence.

The RTC initially directed the Republic to show cause why its complaint should not be dismissed for lack of jurisdiction, eventually dismissing the complaint based on the claim that the challenge essentially called for the review of NCIP Resolution No. 060-2009.
The RTC’s dismissal was premised on the notion that the NCIP, as a quasi-judicial and co-equal body to the RTC, was the proper venue for disputes over ancestral land certification.
The Court of Appeals (CA) affirmed the RTC’s ruling by holding that the RTC did not have jurisdiction, also noting a procedural lapse regarding the timeliness of filing the petition for certiorari under Rule 65.
A petition-in-intervention was also filed by the Heirs of Mateo CariAo and Bayosa Ortega who intended to challenge the constitutionality of Section 53 of the Indigenous Peoples Rights Act (IPRA), though this intervention was later denied for lack of legal interest and proper standing.

The land in question being part of the Baguio Stock Farm (BSF) – a public domain reserved for animal breeding under Presidential Proclamation No. 603.
The OCT being based on a CALT issued via NCIP resolution, with alleged irregularities such as an unapproved survey plan and technical description that misrepresent the actual boundaries of the public land.

The NCIP resolution as being null and void for procedural deficiencies (e.g., failure to include all necessary parties and to secure proper signatures).
The issuance of the CALT and the subsequent OCT as contrary to relevant provisions of the IPRA, particularly in light of conflicting ancestral claims and the reserved nature of the BSF.

The underlying claim sought the reversion of the land to the public domain and the cancellation of any titles derived from the disputed CALT, thereby asserting the RTC’s original jurisdiction over such matters.

Whether the RTC, in the exercise of its original and exclusive jurisdiction over titles to property, has the power to examine a decision or resolution made by a co-equal body like the NCIP, especially when such decision is alleged to be null and void ab initio.
Whether the RTC may choose not to recognize the validity of an NCIP resolution it deems patently void.
Whether a petition for certiorari is the proper remedy to attack the allegedly null NCIP resolution, particularly when the Republic is not a party to the NCIP’s proceedings.
Whether it is appropriate for the Court to finally decide on the substantive merits of the nine causes of action raised in the Complaint before full trial and factual development, or whether such issues should await trial on the merits.
