Case Summary (G.R. No. 145328)

Factual Background: Project Implementation and Community Response

In 1996 NAPOCOR began construction of the transmission line and its supporting towers that traverse areas including the perimeter of Fort Bonifacio and Dasmariñas Village. Petitioners, alarmed by the towers’ proximity to residences, gathered studies and materials linking EMF exposure to illnesses (e.g., cancer, leukemia), engaged NAPOCOR in meetings, and sought redress through legislative channels. NAPOCOR acknowledged negotiations and proposed several alternatives and cost estimates (transfer to Lawton, widening easement, undergrounding, rerouting), but negotiations reached an impasse: petitioners sought relocation to Fort Bonifacio/Lawton; NAPOCOR preferred a 12‑meter easement.

Procedural History: Trial Court Injunctions and NAPOCOR’s Challenge

Petitioners filed a complaint for damages with prayers for a TRO and preliminary injunction on 9 March 2000. The Regional Trial Court (RTC) issued a TRO on 13 March 2000 and extended it on 15 March 2000; subsequently the RTC issued a writ of preliminary injunction on 3 April 2000 enjoining NAPOCOR from energizing the lines and from further preparatory activities, conditioned on a P5,000,000 bond. NAPOCOR filed a petition for certiorari with the Court of Appeals, asserting lack of jurisdiction based primarily on P.D. No. 1818’s prohibition against issuance of injunctions in cases involving government infrastructure projects.

Court of Appeals Decision

On 3 May 2000, the Court of Appeals granted NAPOCOR’s petition and reversed and set aside the RTC’s orders (the TROs and the preliminary injunction), grounding its decision on Section 1 of P.D. No. 1818 and relevant Supreme Court administrative circulars that warned against indiscriminate issuance of injunctions against government infrastructure projects.

Issue Presented to the Supreme Court

Whether the trial court had jurisdiction to issue a TRO and a writ of preliminary injunction enjoining NAPOCOR’s construction and energization activities notwithstanding the general proscription in P.D. No. 1818; whether the petitioners’ allegations—that their right to health was endangered and that NAPOCOR failed to conduct prior consultations—present questions of law sufficient to take the case out of P.D. No. 1818’s protective ambit.

Governing Law and Standards for Injunctive Relief

P.D. No. 1818 generally bars courts from issuing restraining orders or preliminary injunctions in controversies involving government infrastructure projects or public utilities to avoid undue disruption of essential projects. Republic Act No. 8975 (as quoted in the decision) clarifies and strengthens the prohibition while providing an exception for “extreme urgency involving a constitutional issue” where grave injustice and irreparable injury will arise unless a TRO is issued. Rule 58, Section 3, Rules of Court sets the standards for preliminary injunctions: the applicant must show entitlement to relief restraining acts complained of, that continuance of the act would probably work injustice or render judgment ineffectual, or that the act complained of is probably in violation of applicant’s rights. The 1987 Constitution (Article II, Sec. 15) recognizes the State’s duty to protect and promote the right to health. The Local Government Code requires consultation with affected communities and prior approval of the sanggunian for projects.

Supreme Court’s Analysis: Scope and Limits of P.D. No. 1818

The Court reaffirmed that P.D. No. 1818’s prohibition is not absolute. Jurisprudence recognizes that the proscription principally aims to bar injunctions that would interfere with administrative acts involving technical discretion or factual controversies affecting infrastructure projects. However, where disputes raise questions of law—particularly constitutional rights (e.g., right to health) and legal obligations (e.g., mandatory prior consultation)—courts retain the power to issue injunctive relief. The Court therefore rejected a blanket reading of P.D. No. 1818 that would entirely preclude judicial restraint in such circumstances.

Evidence and Probabilistic Determination Justifying a Preliminary Injunction

The Court noted documentary evidence on record supporting petitioners’ concerns: studies and materials linking EMF exposure to serious illnesses, NAPOCOR brochures and representations about required safety easements, correspondence from NAPOCOR’s president acknowledging negotiations and alternatives, and a congressional privilege speech criticizing NAPOCOR’s handling. The Court treated these materials as sufficient indicia of a non‑imaginary risk to health and safety. The potential causal link between EMF exposure and disease, even if not conclusively established, falls within probabilistic proof sufficient for provisional relief. The Court also took judicial notice of geographic risk factors (proximity to earthquake faults, exposure to typhoons) that compound safety concerns.

Application of Rule 58: Probability and Preservation of Status Quo

Applying Rule 58 standards, the Court emphasized that a preliminary injunction is a preservative, provisional remedy that requires probability—not certainty—of rights violation and potential irreparable injury. Given the evidence and the pendency of the main action, preserving the status quo pending final adjudication was appropriate to prevent harm that might render any eventual judgment ineffectual. The Court reiterated that courts must exercise circumspection in granting injunctions but must not be stripped of all remedial power by P.D. No. 1818 where constitutional rights and clear questions of law are at stake.

Consideration of Administrative Circulars and Cautionary Directives

The Court addressed administrative circulars (Circulars Nos. 2‑91, 13‑93, 68‑94 and Administrative Circular No. 7‑99) which counsel against indiscriminate issuance of injunctions against government projects. It held that these circulars do not create an absolute bar; they merely warn judges to exercise prudence and avoid indiscriminate or improper use of provisional remedies. There is no textual basis in those circulars to nullify the courts’ inherent equitable powers when constitutional issues and legal questions ar
