G.R. No. 98332 - Miners Association of the Philippines, Inc. vs. Factoran, Jr.

Case Summary (G.R. No. 98332)

Factual Background

The case arose from the constitutional reconfiguration of State control over natural resources embodied in Article XII, Section 2 of the 1987 Constitution, which prohibited the alienation of most natural resources and required that exploration, development, and utilization be under the full control and supervision of the State. To effect a transition, President Corazon C. Aquino promulgated Executive Order No. 211 to provide interim procedures for mining applications and later Executive Order No. 279 authorizing the DENR Secretary to negotiate and enter into co-production, joint venture, or production-sharing agreements and directing the Secretary to promulgate supplementary rules. Pursuant to Section 6 of Executive Order No. 279, the DENR Secretary issued Administrative Order No. 57 (guidelines on Mineral Production Sharing Agreements), whose Article 9 provided that certain existing mining leases or agreements granted after the effectivity of the 1987 Constitution pursuant to Executive Order No. 211 shall be converted into production-sharing agreements within one year from the guidelines’ effectivity. The Secretary later issued Administrative Order No. 82, which required submission of Letters of Intent and MPSA applications within two years from the effectivity of Administrative Order No. 57 and declared that failure to do so would cause abandonment of mining claims.

Procedural History

Petitioner filed a petition for certiorari attacking the validity of Administrative Order Nos. 57 and 82. The Court issued a Temporary Restraining Order on July 2, 1991 upon petitioner’s urgent ex parte application, conditioned on a P500,000.00 bond, enjoining enforcement of the challenged administrative orders. On November 13, 1991, Continental Marble Corporation sought to intervene alleging prejudice from DENR’s refusal to renew a Mines Temporary Permit; intervention was denied. The petition was resolved by decision of the Court on January 16, 1995.

Petitioner’s Contentions

Petitioner asserted that the DENR Secretary exceeded the rule-making authority granted by Section 6 of Executive Order No. 279 in issuing Administrative Order Nos. 57 and 82. Petitioner argued that the administrative orders effectively repealed or abrogated Presidential Decree No. 463, as amended, and other mining laws that remained in force under Section 7 of Executive Order No. 279, and that Article 9 of Administrative Order No. 57 and Section 3 of Administrative Order No. 82 unlawfully pre-terminated existing mining leases and impaired contractual obligations in violation of Article III, Section 10 of the 1987 Constitution.

Respondents’ Position

Respondents defended the challenged orders as valid exercises of the rule-making power conferred by Section 6 of Executive Order No. 279 to implement the constitutional mandate in Article XII, Section 2 of the 1987 Constitution. They maintained that the parts of Presidential Decree No. 463, as amended, dealing with licenses, concessions or leases were inconsistent with the Constitution and thus foreclosed, and that the administrative orders did not effect automatic unilateral conversion of leases but provided procedures for negotiated production-sharing agreements in furtherance of the State’s policy and public welfare.

Issues Presented

The Court addressed whether the DENR Secretary acted in excess of delegated rule-making power in issuing Administrative Order Nos. 57 and 82; whether those orders unlawfully repealed or abrogated provisions of Presidential Decree No. 463, as amended, and other mining laws; and whether the administrative orders violated Article III, Section 10 by impairing vested contractual rights through automatic conversion or by causing abandonment of mining claims for failure to comply with administrative filing requirements.

Ruling of the Court

The Court dismissed the petition for lack of merit and lifted the Temporary Restraining Order previously issued. The petition-in-intervention filed by Continental Marble Corporation was denied.

Legal Basis and Reasoning

The Court began with the settled rule that administrative regulations must be in harmony with the statute from which they draw authority and must be confined to carrying into effect the law’s general provisions, citing United States v. Barrias, United States v. Tupasi Molina, and People v. Maceren. The Court found no grave abuse of discretion in the promulgation of Administrative Order Nos. 57 and 82 because Section 6 of Executive Order No. 279 expressly authorized the Secretary to issue supplementary rules necessary for effective implementation. The Court analyzed Executive Order No. 279 as an implementing law of Article XII, Section 2, and held that where provisions of Presidential Decree No. 463, as amended, were inconsistent with the new constitutional regime—particularly those provisions authorizing "license, concession or lease"—those provisions had been foreclosed upon the effectivity of the 1987 Constitution. Section 7 of Executive Order No. 279 preserved only those provisions of PD 463 and other mining laws that were not inconsistent with the Executive Order and the Constitution. The Court further held that mining leases or agreements granted after the Constitution took effect pursuant to Executive Order No. 211 were expressly made subject to modifications or alterations, and therefore the non-impairment clause of Article III, Section 10 did not preclude reasonable legislative or regulatory changes affecting those instruments. The Court invoked the primacy of the police power where measures are reasonably adapted to public welfare, citing Ongsiako v. Gamboa and Ramas v. CAR and Ramos, and read Executive Order No. 279 as a valid exercise of transitional legislative authority that could modify privileges and terms granted under the in
