In the Philippines, a preliminary injunction—a court order to temporarily stop an action—requires a clear demonstration of the right being protected and proof of potential irreparable harm. The Supreme Court in this case clarified that a company seeking to prevent another from constructing a billboard that blocks its “line of sight” must convincingly show it has the right to that unobstructed view and that the potential financial losses cannot be adequately compensated. This means businesses cannot easily halt competitors’ projects without solid legal grounds and evidence of unique, unquantifiable damages.

Whose View Is It Anyway? Squabbles over Signage, ‘Line of Sight,’ and Legal Rights

The dispute arose between Power Sites and Signs, Inc. (Power Sites) and United Neon, both companies engaged in the outdoor advertising business. Power Sites sought a preliminary injunction to stop United Neon from constructing a billboard that allegedly blocked Power Sites’ own advertising sign. The core of the legal issue was whether Power Sites had a clear right to an unobstructed “line of sight” and whether the potential harm it might suffer qualified as the kind of “grave and irreparable injury” that justifies a preliminary injunction.

The case unfolded in Muntinlupa City, where both companies vied for prime billboard locations. Power Sites claimed it had secured the necessary permits to construct a billboard on a specific site. However, United Neon began installing its own billboard just one meter away, allegedly obstructing Power Sites’ sign. This led Power Sites to seek legal recourse, arguing that United Neon’s actions would cause significant financial losses. In response, United Neon asserted it had prior rights to the location, citing its lease agreement with the property owner and its registration with the Outdoor Advertising Association of the Philippines (OAAP).

Initially, the Regional Trial Court (RTC) granted Power Sites’ request for a preliminary injunction, ordering United Neon to cease construction and dismantle its existing sign. However, the Court of Appeals (CA) reversed this decision, finding that Power Sites’ right to the “line of sight” was not clear and that the potential damages could be adequately compensated with monetary relief. Power Sites then elevated the case to the Supreme Court.

At the heart of the Supreme Court’s analysis was the legal framework for granting preliminary injunctions. The Court reiterated that such relief is only warranted when the applicant demonstrates a clear entitlement to the right being protected and a threat of grave and irreparable injury. This injury must be actual, substantial, and demonstrable. The Court emphasized that the standard is even higher for preliminary mandatory injunctions, which compel a party to take action rather than simply refrain from it. Mandatory injunctions are reserved for cases of extreme urgency, where the right is very clear and the potential harm to the applicant is significant.

The Supreme Court examined whether Power Sites had sufficiently established its right to an unobstructed “line of sight.” The Court noted conflicting claims: both parties asserted they began construction first and were entitled to protection under the National Building Code and OAAP Code of Ethics/Guidelines. Since the trial court was better positioned to determine which billboard was constructed first, their actual location, and whether or not an existing billboard was obstructed by another, it would decide whether or not the party requesting the injunction possessed that deserved legal protection.

Crucially, the Court found the evidence presented by Power Sites to be weak and inconclusive, thereby highlighting questions over the relationship between the requesting party and another corp who secured permits for construction on site. Additionally, it wasn’t immediately clear why Power Sites would be granted injunctive relief, with the issuance of required clearance only extended to HCLC Resources. This created further gaps in supporting documentation, thus the Supreme Court reemphasized fundamental legal distinctions that outline separate status between corporations. Overall, more questions over the request than there were answers.

In reaching its decision, the Court also addressed the issue of “grave and irreparable injury.” It found that the damages alleged by Power Sites—loss of profits and potential damage claims from clients—were quantifiable and did not meet the legal definition of irreparable harm. According to settled doctrine, damages are considered irreparable when there is no standard by which their amount can be measured with reasonable accuracy. As a result, a writ of injunction should only issue when an action for damages would adequately compensate injuries caused. Consequently, because the losses described were readily quantifiable, they did not justify the imposition of a preliminary injunction.

The Supreme Court ultimately affirmed the Court of Appeals’ decision, dissolving the preliminary injunction issued by the RTC. The ruling reinforces the principle that preliminary injunctions are extraordinary remedies that should be granted cautiously and only when the legal right is clear and the potential harm is truly irreparable. The Supreme Court refused to entertain the petition based on this decision, effectively declaring that neither the right of line of sight or of harm had sufficient standing under a more detailed analysis.
