Mining Rights vs Indigenous Rights: Prior Consent Is Paramount for MPSA Renewal

The Supreme Court has settled a critical question in Philippine mining law: can a mining company renew its Mineral Production Sharing Agreement (MPSA) without securing the Free and Prior Informed Consent (FPIC) of indigenous peoples whose ancestral domains are affected? In Lone Congressional District of Benguet Province v. Lepanto Consolidated Mining Company (G.R. Nos. 244063 and 244216, June 21, 2022), the Court answered with a firm no. The ruling affirms that indigenous peoples' rights to their ancestral lands are a paramount public policy that cannot be set aside by contract, arbitration, or claims of vested rights.

The Dispute Over MPSA No. 001-90

In 1990, the government entered into MPSA No. 001-90 with Lepanto Consolidated Mining Company and Far Southeast Gold Resources, Inc. The agreement covered a vast tract of land in Mankayan, Benguet, which overlaps with the ancestral domains of the Mankayan Indigenous Cultural Communities/Indigenous Peoples (ICCs/IPs). The MPSA had an initial 25-year term, renewable for another 25 years.

When the MPSA was about to expire in 2015, the mining companies sought renewal. The Mines and Geosciences Bureau (MGB) informed them that the renewal would require certification from the National Commission on Indigenous Peoples (NCIP), including the FPIC of affected ICCs/IPs, as mandated by the Indigenous Peoples' Rights Act of 1997 (IPRA).

The mining companies objected. They argued that the IPRA requirement would impair their alleged vested right to renew under the original terms. They initiated arbitration under the MPSA's arbitration clause.

The Arbitration and the Courts

The arbitral tribunal ruled in favor of the mining companies, holding that the FPIC and NCIP certification could not be imposed as a precondition for renewal. The tribunal reasoned that the requirement was not stipulated in the MPSA and would amount to confiscation of the companies' investments.

The Regional Trial Court vacated the arbitral award, citing public policy. The Court of Appeals reversed, reinstating the award. The case reached the Supreme Court.

The Supreme Court's Ruling

The Supreme Court ruled in favor of the Republic and the indigenous communities. The Court held that the arbitral award must be vacated because it manifestly disregarded the law and violated public policy.

Consent is a constitutional and statutory mandate. The Court emphasized that protecting the rights of ICCs/IPs to their ancestral domains is a constitutionally declared state policy. Section 59 of the IPRA explicitly requires that no department or government agency shall issue, renew, or grant any concession, license, or lease, or enter into any production-sharing agreement, without prior NCIP certification that the area does not overlap with ancestral domains. Such certification requires the FPIC of the affected ICCs/IPs.

Arbitral awards are not absolute. While arbitration awards are generally final and binding, the Court clarified that this autonomy is not absolute. Under Rule 19.10 of the Special ADR Rules, an award may be vacated if it violates public policy. The Court found that the arbitral tribunal did not merely err in interpreting the law—it manifestly disregarded the IPRA and its underlying public policy.

No vested right to renewal. The Court rejected the mining companies' claim of a vested right to renewal under the same terms. The IPRA's certification precondition applies to renewals, and the protection of indigenous peoples' rights cannot be defeated by contractual stipulations or claims of substantial investments.

Intervention in arbitration is not allowed. The Court also ruled that the Province of Benguet could not intervene in the arbitration proceedings. The Special ADR Rules do not provide for intervention, reflecting the principle of party autonomy in arbitration. The State, through the Republic, adequately represents the interests of the ICCs/IPs.

Practical Takeaways

• FPIC is non-negotiable. Mining companies seeking to renew MPSAs covering ancestral domains must secure the FPIC of affected ICCs/IPs and obtain NCIP certification. Failure to do so is a ground to invalidate the renewal.

• Contract terms cannot override IPRA. Even if an MPSA contains a renewal clause, it cannot exempt a company from the IPRA's mandatory requirements. The IPRA's public policy protections prevail over contractual stipulations.

• Arbitration has limits. While arbitration is a favored mode of dispute resolution, arbitral awards that manifestly disregard the law or violate public policy will be vacated by courts.

• The State represents indigenous interests. Government agencies, not local governments or third parties, are the proper parties to assert the rights of ICCs/IPs in disputes involving ancestral domains.

• Vested rights claims are weak. Substantial investments in mining operations do not create vested rights to renewal that override the IPRA's consent requirements.
