Non-Delegation Doctrine Shields Indigenous Rights in Mining Agreements

The Supreme Court has reaffirmed that government powers delegated by law cannot be passed on without proper authority, striking down a mining compliance certificate that threatened the ancestral lands of the Mamanwa Tribes in Surigao del Norte. In Shenzhou Mining Group Corp. v. Mamanwa Tribes of Barangay Taganito and Urbiztondo (G.R. No. 206685, March 16, 2022), the Court applied the principle potestas delegata non potest delegari—"what has been delegated cannot be delegated"—to protect indigenous communities from unauthorized government action.

The Facts

The Mamanwa Tribes hold a Certificate of Ancestral Domain Title over lands in Claver, Surigao del Norte. In 2010, they signed a Memorandum of Agreement with Shenzhou Mining Group Corporation, believing the company held a valid Mineral Production Sharing Agreement. The agreement was co-signed by the National Commission on Indigenous Peoples (NCIP) through its Chairperson.

Commissioner Felecito Masagnay later issued Compliance Certificate Control No. CCRXIII-19-02-13, certifying that Shenzhou had complied with the free and prior informed consent process required under Republic Act No. 8371 (the Indigenous Peoples' Rights Act).

The Mamanwa Tribes soon discovered problems: Shenzhou was not the true contractor of the mineral production sharing agreement, and promised royalty payments of P5 million per quarter went unpaid. They filed a petition with the NCIP to cancel the certificate.

The Issue

The central question: Did the NCIP correctly declare void a compliance certificate signed by Commissioner Masagnay, who acted under a delegation of authority from the NCIP Chairperson?

The Ruling

The Supreme Court denied Shenzhou's petition and affirmed the nullity of the certificate. The Court held that the power to issue certification preconditions is vested by law in the NCIP as a body, not in any individual commissioner. The NCIP, acting En Banc, had delegated this power to its Chairperson through Resolution No. 007, series of 2010.

When Chairperson Insigne later designated Commissioner Masagnay as officer-in-charge and authorized him to sign compliance certificates, this constituted an unauthorized redelegation. As the Court explained, the Chairperson was himself a delegatee of the Commission's power—and a power once delegated cannot be redelegated without the delegating authority's consent.

The Court rejected Shenzhou's argument that Masagnay was a de facto officer whose acts should be upheld. The doctrine of de facto officer requires an appointment or election to an office. Masagnay was merely designated as officer-in-charge, not appointed to the Chairperson's position. A designation, the Court noted, merely imposes additional duties on an incumbent official—it does not confer the authority of another office.

The Legal Framework

Section 59 of Republic Act No. 8371 requires all government agencies to obtain certification from the NCIP before granting concessions, licenses, or production sharing agreements affecting ancestral domains. This certification can only be issued after field-based investigation and with the free and prior informed consent of the indigenous cultural communities concerned.

The NCIP's mandate, under Section 39 of the same law, is to protect and promote the interests and well-being of indigenous peoples. The Court emphasized that this protective function is why the certification requirement exists—it ensures that no project proceeds within ancestral domains without the genuine consent of the communities who own them.

Practical Takeaways

• Delegated powers are strictly construed. When a government body delegates authority to an official, that official cannot pass the power to another without explicit permission from the delegating body.
• Designation is not appointment. An officer-in-charge designated to perform another official's tasks does not gain the authority of that office, and the de facto officer doctrine does not apply.
• Indigenous consent is non-negotiable. Mining and other development projects within ancestral domains require valid certification precondition from the NCIP, issued with proper authority and genuine free and prior informed consent.
• Void acts have no legal effect. A compliance certificate issued without authority is void ab initio—it cannot be the source of rights or obligations, and agreements premised on it are likewise void.
• Royalties must still be paid. Even when a certificate is voided, companies must pay agreed royalties until they return possession of the ancestral lands to their rightful owners.
