In the case of Republic of the Philippines vs. Marcopper Mining Corporation, the Supreme Court clarified the jurisdiction of the Pollution Adjudication Board (PAB) in relation to mining operations. The Court ruled that the PAB retains its authority to adjudicate pollution cases, even those connected with mining activities, despite the enactment of the Philippine Mining Act of 1995. This decision ensures that environmental protection remains a priority, alongside the regulation of mining activities, by maintaining the PAB’s oversight in pollution-related issues.

Calancan Bay’s Rehabilitation: Who Decides on Mining Pollution?

The legal battle stemmed from Marcopper Mining Corporation’s (MMC) alleged failure to continue contributing to the Ecology Trust Fund (ETF) for the Calancan Bay Rehabilitation Project (CBRP). MMC had been ordered to deposit P30,000 daily into the ETF as part of a cease and desist order related to the discharge of mine tailings into Calancan Bay. The Pollution Adjudication Board (PAB) sought to compel MMC to pay its arrears, leading to a challenge on the PAB’s jurisdiction over pollution cases involving mining operations, particularly after the passage of the Philippine Mining Act of 1995 (RA 7942). The central legal question was whether RA 7942 had stripped the PAB of its authority to hear pollution cases connected with mining, effectively transferring that power to the Mines Regional Director.

The Supreme Court, in its analysis, delved into the history and purpose of relevant environmental and mining laws. Republic Act No. 3931, later revised by Presidential Decree No. 984, aimed to maintain water and air quality standards, establishing the National Pollution Control Commission (NPCC), which later became the PAB. Executive Order No. 192 further solidified the PAB’s role, granting it broad powers to adjudicate pollution cases. In contrast, RA 7942, the Philippine Mining Act of 1995, focused on regulating mining activities, promoting safety, and ensuring environmental protection within mining operations. It granted the Mines Regional Director the power to issue orders related to safety and anti-pollution measures within mining sites.

The Court emphasized that repeals by implication are disfavored in law. For a subsequent law to repeal a prior one, the two must be absolutely incompatible. The Supreme Court cited the maxim, “interpretare et concordare leqibus est optimus interpretendi,” meaning every statute must be interpreted to harmonize with other laws to form a uniform system of jurisprudence. The Court found no such irreconcilable conflict between RA 7942 and RA 3931, as amended by PD 984 and EO 192. Instead, it viewed the authority of the Mines Regional Director as complementary to that of the PAB.

The Supreme Court quoted Section 19 of EO 192, emphasizing the PAB’s broad powers to adjudicate pollution cases. Further, it quoted Section 6 of PD 984, which includes the power to issue orders compelling compliance with pollution control regulations, make orders requiring the discontinuance of pollution, and issue permits for the discharge of sewage and industrial waste. These provisions highlight the PAB’s comprehensive mandate to address pollution issues. The Court noted that RA 7942 did not explicitly repeal these provisions or transfer adjudicative power over pollution cases to the Mines Regional Director. The director’s authority is primarily administrative and regulatory, focused on ensuring compliance within mining operations, whereas the PAB retains the power to adjudicate complaints for violations of pollution control statutes.

SEC. 19.  Pollution Adjudication Board. – There is hereby created a Pollution Adjudication Board under the Office of the Secretary.  The Board shall be composed of the Secretary as Chairman, two (2) Undersecretaries as may be designated by the Secretary, the Director of Environmental management, and three (3) others to be designated by the Secretary as members.  The Board shall assume the powers and functions of the Commission/Commissioners of the National Pollution Control Commission with respect to the adjudication of pollution cases under Republic Act 3931 and Presidential Decree 984, particularly with respect to Section 6 letters e, f, g, j, k, and p of P.D. 984.  The Environmental Management Bureau shall serve as the Secretariat of the Board.  These powers and functions may be delegated to the regional offices of the Department in accordance with rules and regulations to be promulgated by the Board.

Building on this principle, the Court clarified that the role of the Mines Regional Director is to ensure safety and environmental protection *within* mining operations. They have the authority to issue orders and suspend operations to remedy practices that violate safety and anti-pollution laws. However, this regulatory power does not extend to adjudicating broader pollution complaints, which remains the purview of the PAB. This division of authority ensures that both mining activities and environmental concerns are adequately addressed by specialized bodies.

The Court also addressed the argument that the creation of the Panel of Arbitrators and the Mines Adjudication Board under RA 7942 implied a transfer of adjudicative power over pollution cases. It clarified that these bodies are primarily concerned with resolving disputes related to mining rights, mineral agreements, and surface owner issues, not with adjudicating violations of pollution laws and regulations. Therefore, the PAB’s authority remains intact.

The Supreme Court, however, sided with Marcopper on the issue of arrears in deposits to the Ecology Trust Fund (ETF). The Court pointed to the testimony of Mr. Edel Genato, a technical resource person for the PAB, who admitted that the funds in the ETF were more than sufficient to cover the costs of rehabilitation. Further, the Court noted that the Office of the President had not objected to Marcopper’s manifestation that it would stop payments after ceasing to dump mine tailings into the bay. Given these facts, the Court deemed it unfair to compel Marcopper to continue making deposits when the existing funds were adequate for the rehabilitation project.
