CASE DIGEST : Bayan Muna Party-List Representatives Satur C. Ocampo, et al. v. President Gloria Macapagal-Arroyo, et al. G.R. No. 182734, January 10, 2023 GAERLAN

The petitioners, composed of members of Congress and party-list representatives, filed a Petition for Certiorari and Prohibition questioning the constitutionality of the Tripartite Agreement for Joint Marine Seismic Undertaking (JMSU) entered into in 2005 by the Philippine National Oil Company (PNOC), the China National Offshore Oil Corporation (CNOOC), and the Vietnam Oil and Gas Corporation (PETROVIETNAM). The JMSU authorized the parties to jointly conduct seismic studies over approximately 142,886 square kilometers of the South China Sea, including areas within the Philippines' exclusive economic zone (EEZ) and continental shelf. Petitioners argued that the agreement effectively allowed foreign state-owned corporations to participate in the exploration of Philippine natural resources without complying with the requirements of the 1987 Constitution.

The respondents contended that the JMSU was merely a pre-exploration seismic survey intended to gather geological data and did not constitute the actual exploration, development, or utilization (EDU) of natural resources. They further argued that the agreement had already expired, rendering the petition moot. The Supreme Court nevertheless took cognizance of the case because it involved issues of transcendental public importance, particularly the constitutional limitations on the State's management of natural resources and the protection of Philippine sovereignty over its maritime zones. The Court examined Section 2, Article XII of the 1987 Constitution, which provides that the exploration, development, and utilization of natural resources shall remain under the full control and supervision of the State, and that foreign corporations may participate only through agreements expressly authorized by the Constitution.

ISSUE

Whether the Joint Marine Seismic Undertaking (JMSU) violated Section 2, Article XII of the 1987 Constitution by allowing foreign state-owned corporations to participate in the exploration of petroleum resources within Philippine territory and maritime zones without the constitutional safeguards governing the exploration, development, and utilization of natural resources.

Whether the expiration of the JMSU rendered the petition moot, or whether the Court should still rule on its constitutionality considering the issues raised involve the protection of the State's sovereign rights over its natural resources and the interpretation of constitutional limitations on foreign participation in their exploration.

HELD

The Supreme Court granted the petition and declared the JMSU unconstitutional. It ruled that the seismic surveys authorized under the agreement constituted an integral part of the exploration of petroleum resources. Under Section 2, Article XII of the 1987 Constitution, all exploration, development, and utilization of the country's natural resources must remain under the full control and supervision of the State. Foreign corporations may participate only through constitutionally authorized arrangements, such as Financial or Technical Assistance Agreements (FTAAs) involving large-scale exploration, development, and utilization of minerals, petroleum, and other mineral oils, and only under terms prescribed by law. Since the JMSU allowed foreign state-owned corporations to jointly undertake exploration activities outside these constitutional mechanisms, it violated the Constitution.

The Court likewise held that the case was not rendered moot by the expiration of the JMSU because it involved constitutional questions of exceptional public importance capable of guiding future government actions. It emphasized that the State cannot circumvent constitutional restrictions by characterizing exploration activities as mere "seismic studies" when such activities are essential components of resource exploration. The ruling reaffirmed the Regalian Doctrine, under which the State retains ownership of all natural resources and must exercise full control over their exploration and utilization. Consequently, the Supreme Court declared the JMSU void for being contrary to Section 2, Article XII of the Constitution, thereby reinforcing the constitutional protection of Philippine sovereignty and national patrimony
