In a dispute over the installation of transmission lines, the Supreme Court of the Philippines clarified the intersection between the right to health and the right to a balanced and healthful ecology. The Court ruled that while the right to health can be invoked in environmental cases, petitioners must demonstrate a direct and significant environmental impact that prejudices the health of inhabitants across multiple cities or provinces. This decision underscores the importance of balancing infrastructure development with environmental protection and public health concerns, setting a high bar for proving environmental damage in cases involving public utilities.

Power Lines and People’s Well-being: Did MERALCO’s Project Violate Residents’ Rights?

This case originated from the Manila Electric Company’s (MERALCO) project to supply electricity to the Ninoy Aquino International Airport Terminal III (NAIA III). To achieve this, MERALCO installed transmission lines along 10th, 12th, and 27th Streets in Barangay 183, Pasay City. Residents, concerned about the potential health risks from electromagnetic fields emitted by these high-tension wires, filed a Petition for Issuance of a Writ of Kalikasan, arguing that their right to a balanced and healthful ecology was violated. The central legal question was whether the installation of these transmission lines posed a significant threat to the residents’ health and environment, warranting the intervention of the court through the extraordinary remedy of a writ of kalikasan.

The petitioners, residents of Barangay 183 and Magallanes Village, claimed that the transmission lines endangered their health due to prolonged exposure to electromagnetic fields, which some studies linked to increased risks of leukemia and other cancers, especially in children. They also argued that MERALCO failed to conduct prior public consultations before commencing the project, violating Section 27 of the Local Government Code. MERALCO, on the other hand, maintained that it had complied with all legal requirements, secured necessary permits, and ensured that the electromagnetic fields emitted by the transmission lines were within safe limits, as certified by the Department of Health.

The Court of Appeals initially denied the petition, stating that the petitioners failed to sufficiently prove the causal link between the transmission lines and the alleged health risks. The appellate court also noted that MERALCO had complied with relevant environmental laws and safety standards. Dissatisfied, the residents elevated the case to the Supreme Court, reiterating their claims and invoking the precautionary principle, which calls for action to prevent potential harm even in the absence of full scientific certainty.

The Supreme Court, in its analysis, addressed several key issues. First, it tackled the procedural question of forum shopping, which occurs when a party repetitively avails themselves of multiple judicial remedies based on the same facts and issues. While acknowledging that the residents had previously filed a petition for prohibitory injunction, the Court found that the writ of kalikasan case did not constitute forum shopping because there was no complete identity of parties, as the earlier case involved a smaller group of residents and any decision on the prohibitory injunction case cannot operate as res judicata on the other residents of Barangay 183.

The Court then delved into the substantive issue of whether the installation of transmission lines violated the residents’ right to a balanced and healthful ecology. The Court underscored that to be granted the privilege of a writ of kalikasan, three requisites must be satisfied. First, the petitioner must sufficiently allege and prove “the actual or threatened violation of the constitutional right to a balanced and healthful ecology.” Second, “the actual or threatened violation [must arise] from an unlawful act or omission of a public official or employee, or private individual or entity.” Third, “the actual or threatened violation [must involve] or [must be shown to lead to] an environmental damage of such magnitude as to prejudice the life, health or property of inhabitants in two or more cities or provinces.”

Addressing the connection between the right to health and the right to a balanced and healthful ecology, the Court stated that “a petition for the issuance of a writ of kalikasan may be brought if actual or threatened violation to the right to health may be proved.” However, the Court found that the petitioners failed to prove any unlawful act on the part of MERALCO. Specifically, the Court highlighted that while the Implementing Rules of the Code on Sanitation originally prohibited high-tension transmission lines from passing over residential areas, this rule had been amended.

Moreover, the Court emphasized that MERALCO had complied with the Philippine Electrical Code, which sets standards for horizontal and vertical clearances for transmission lines. The Court of Appeals found that MERALCO’s transmission lines had clearances exceeding these minimum requirements. In light of the fact that the Department of Health Administrative Order No. 003-07 set the reference levels for general public exposure to electromagnetic fields to 83.33 µT or 833.33 mG, the Court reiterated the certification by the Bureau of Health Devices and Technology under the Department of Health, the transmission lines emitted “extremely low frequency” electromagnetic fields “within the International Commission on Non-Ionizing Radiation Protection limits of exposure to the general public.”

The Court also concluded that petitioners did not prove the third requisite to demonstrate the magnitude of the actual or threatened environmental damage as to prejudice the life, health, or property of inhabitants in two or more cities or provinces. The ecological threats addressed by the writ of kalikasan must be of “potentially exponential nature” and “large-scale,” which, if not prevented, may result in “an actual or imminent environmental catastrophe.” Here, the alleged environmental damage was not shown to be potentially exponential in nature; nor was it shown to be large-scale, involving a narrow strip running between two barangays.

Finally, the Court addressed the invocation of the precautionary principle. It held that the precautionary principle did not apply in this case because regulatory precautions had already been taken. To that end, the Department of Health, in Administrative Order No. 003-07, had already set the reference levels or limits for general public exposure to time-varying electric and magnetic fields, and it was determined that the respondent MERALCO had complied with these limits. The Court stated that to “prohibit the installation works in Barangay 183 is to disrupt air travel to and from Manila. Stopping the installation works would be a regulatory policy too costly to implement, considering that ‘the operation of international airport terminals is an undertaking imbued with public interest.’ This, adding the lack of proof of the magnitude of the environmental damage that might be caused by the installation works in Barangay 183, renders this Court unable to grant any of the remedies under the writ of kalikasan.”
