CASE DIGEST
1. Case Title
Lone Congressional District of Benguet Province v. Lepanto Consolidated Mining Co. and Far Southeast Gold Resources, Inc.
Republic of the Philippines v. Lepanto Consolidated Mining Co. and Far Southeast Gold Resources, Inc.
G.R. Nos. 244063 and 244216,
Decision: June 21, 2022,
Ponente: Justice Mario Lopez Inting
Facts
1. In 1990, the Philippine government through the DENR entered into Mineral Production Sharing Agreement (MPSA) No. 001-90 with Lepanto Consolidated Mining Co. and Far Southeast Gold Resources, Inc.
2. The MPSA granted the companies the right to conduct mining operations in Mankayan, Benguet for 25 years, renewable for another 25 years.
3. The mining area overlaps with the ancestral domain of Indigenous Cultural Communities/Indigenous Peoples (ICCs/IPs).
4. After the MPSA was executed, Congress enacted two important laws:
RA 7942 – Mining Act of 1995
RA 8371 – Indigenous Peoples’ Rights Act (IPRA) of 1997
5. Section 59 of IPRA requires that government agencies may not issue or renew mining permits without certification from the National Commission on Indigenous Peoples (NCIP) and Free and Prior Informed Consent (FPIC) from the affected indigenous community.
6. As the MPSA approached expiration in 2015, the DENR required the companies to obtain FPIC and NCIP certification before renewal.
7. Lepanto and FSGR objected, arguing that:
the original contract gave them vested rights to renewal, and
the FPIC requirement was new legislation not contemplated in the contract.
8. The companies initiated arbitration, invoking the arbitration clause in the MPSA.
9. The Arbitral Tribunal ruled in favor of the mining companies, declaring that the FPIC requirement could not be imposed on the renewal because it impaired their contractual rights.
10. The RTC vacated the arbitral award, holding that the issue involved public policy concerning indigenous peoples’ rights.
11. The Court of Appeals reversed the RTC and reinstated the arbitral award.
12. The Republic of the Philippines and the Lone Congressional District of Benguet elevated the case to the Supreme Court.
Issues
1. Whether the dispute involving FPIC and ancestral domain protection can be resolved through arbitration.
2. Whether the renewal of the MPSA requires compliance with the FPIC requirement under the IPRA.
3. Whether contractual rights under the MPSA override the State policy protecting indigenous peoples’ ancestral domains.
Ruling
The Supreme Court GRANTED the petitions.
The Court:
SET ASIDE the Court of Appeals decision, and
VACATED the arbitral award in favor of Lepanto and FSGR.
The Court held that FPIC is mandatory for the renewal of mining agreements affecting ancestral domains.
Ratio Decidendi
1. Protection of Indigenous Peoples is a Constitutional Policy
The Constitution mandates the State to recognize and protect the rights of indigenous cultural communities to their ancestral lands.
Thus, mining activities affecting ancestral domains must comply with statutory safeguards under the IPRA.
2. FPIC is a Mandatory Legal Requirement
Section 59 of the IPRA requires:
NCIP certification, and
Free and Prior Informed Consent (FPIC)
before any mining permit, license, or agreement affecting ancestral domains may be issued or renewed.
Therefore, renewal of the MPSA cannot proceed without FPIC.
3. Public Policy Cannot Be Overridden by Arbitration
The Court ruled that:
arbitration cannot decide matters involving public policy and sovereign regulatory powers.
The protection of ancestral domains is a matter of public policy, not merely a contractual dispute.
Hence:
Private arbitration cannot nullify statutory protections granted to indigenous peoples.
4. No Vested Right to Renewal Without Compliance with Law
The Court rejected the argument that Lepanto had vested rights to renewal.
The clause allowing renewal “upon terms provided by law” necessarily subjects the renewal to new legislation such as the IPRA.
Thus:
Renewal is not automatic and must comply with prevailing laws.
Doctrine
The case established the following important doctrines:
1. FPIC under the IPRA is a mandatory condition for mining projects affecting ancestral domains.
2. Arbitration cannot override public policy involving indigenous peoples’ rights and environmental regulation.
3. Mining agreements with renewal clauses remain subject to subsequently enacted laws protecting indigenous communities.
4. The State’s police power and constitutional duty to protect ancestral domains prevail over contractual claims of vested rights.
Significance in Philippine Law
This ruling is now considered a leading case in environmental and indigenous peoples’ law because it:
strengthens IPRA enforcement,
limits arbitration in matters of public policy, and
confirms that mining rights are subordinate to indigenous land rights.
The decision has had practical consequences, including the requirement that Lepanto secure FPIC from affected communities before the renewal of its Benguet mining agreement.
