Why the Supreme Court Struck Down 24/7 Tracking of Fishing Boats

Continuous location tracking revealed proprietary fishing grounds, exceeded what the Fisheries Code authorizes, and exempted municipal vessels without justification.

News hook: On August 3, 2026 the Supreme Court En Banc, in a decision written by Associate Justice Maria Filomena D. Singh, upheld a Regional Trial Court ruling declaring Fisheries Administrative Order No. 266 unconstitutional, dismissing the petition of the Republic through the Department of Agriculture and the Bureau of Fisheries and Aquatic Resources. The order had required all commercial Philippine-flagged fishing vessels to carry a Vessel Monitoring System and an Electronic Reporting System. BFAR filed a motion for reconsideration on August 14, 2026.

Legal question

When can a government agency require continuous electronic monitoring of a regulated business — and what makes such a regulation unconstitutional?

Applicable laws and rules

Why this matters

This is, on its face, a fisheries case. It matters far beyond fisheries because of how the Court decided it: an administrative issuance was struck down for failing the most deferential standard of constitutional review available.

The rational basis test is normally close to a formality — the government need only show a legitimate interest and a reasonable connection between that interest and the means chosen. Losing under it means the agency could not demonstrate that its regulation actually did what it claimed.

The ruling also sets out concrete requirements for the consultation and scientific-study process behind agency rulemaking. Those requirements apply well beyond BFAR, to any agency required by its enabling statute to consult stakeholders and to base issuances on scientific evidence.

The regulatory background

The Philippine Fisheries Code of 1998, RA 8550, was enacted to protect food security through sustainable management and conservation of fishery resources. In 2015 it was amended by RA 10654 to strengthen measures against illegal, unreported, and unregulated (IUU) fishing, and it directed the Department of Agriculture to establish monitoring systems. Fishing vessels were required to comply with Vessel Monitoring Measures, which include a Vessel Monitoring System (VMS) to track and monitor vessels and an Electronic Reporting System (ERS) to record and transmit fisheries data.

BFAR issued FAO No. 260 in 2018, initially covering commercial Philippine-flagged vessels targeting migratory fish stocks. In 2020, FAO No. 266 expanded coverage to all commercial Philippine-flagged fishing vessels, requiring VMM and ERS and a Maritime Mobile Service Identity number from the National Telecommunications Commission.

Royale Fishing Corporation, Bonanza Fishing and Market Resources, Inc., and RBL Fishing Corporation challenged FAO No. 266 in the RTC, arguing that continuous monitoring violated their constitutional rights, exposed confidential business information and trade secrets, and denied equal protection because only commercial vessels had to comply even though the Fisheries Code also covers municipal and distant-water vessels. The RTC declared FAO No. 266 unconstitutional, and the Supreme Court affirmed.

Failing the rational basis test

The Court explained that different standards apply in reviewing government regulations: stricter standards for regulations affecting fundamental rights and certain classifications, and the rational basis test for everything else. Under the rational basis test the government must show a legitimate interest and a reasonable connection between that interest and the methods used.

The Republic failed. The Court found it had not adequately proved that the VMS and ERS requirements were reasonably connected to preventing IUU fishing violations. Specifically:

That second point is the heart of it. A regulation that duplicates existing reporting while adding continuous surveillance has a weak claim to being reasonably connected to its stated purpose.

Exceeding the statute: what "monitoring" means

The Court also held that FAO No. 266 authorized monitoring beyond what RA 8550, as amended, allows. The Fisheries Code defines "monitoring" as the continuous observation of fishing effort, expressed through factors such as the number of days or hours of fishing, characteristics of fishery resources, and resource yields.

That definition, the Court held, does not extend to continuous tracking of the locations or destinations of commercial fishing vessels. RA 10654 does not require operators to disclose their location 24/7, and the Court expressly recognized that fishing grounds constitute proprietary business information.

This is a straightforward ultra vires holding with wide application. An implementing rule cannot enlarge the statute it implements; where an agency's enabling law defines a term, the agency cannot expand that definition by regulation.

Equal protection: why exempting municipal vessels mattered

The Court held FAO No. 266 also violated the equal protection clause. RA 8550, as amended, envisions a single monitoring, control, and surveillance system covering all Philippine-flagged fishing vessels, whether municipal or commercial. Excluding municipal fishing vessels from mandatory VMS was discriminatory because there is an equal need to monitor them, and data showed that they too have a significant impact on marine resources.

The equal protection analysis in Philippine law asks whether a classification rests on substantial distinctions germane to the purpose of the law, is not limited to existing conditions only, and applies equally to all members of the class. A classification that excludes a group with the same relevant impact on the regulated harm does not satisfy that test.

Due process in rulemaking: consultation is not a formality

The most transferable part of the ruling concerns process. The Republic argued that FAO No. 266 complied with the Fisheries Code's procedural requirements because it was based on scientific studies and consultations with affected stakeholders. The Court disagreed, holding that the law requires transparency not only in conducting consultations but also in selecting the scientific studies supporting the issuance. Specifically, stakeholders must be:

  1. Informed of the studies relied upon;
  2. Allowed to nominate experts; and
  3. Given the opportunity to comment on those studies.

None of those safeguards was met. The Court noted that the only study BFAR cited was outdated and never presented during the consultations, and that BFAR had already procured the VMS transceivers — the implication being that the consultation was conducted after the decision had effectively been made.

For anyone dealing with any Philippine regulator, that is the practical template: a consultation in which the evidence base is withheld, or which occurs after procurement and commitment, is vulnerable to a due process challenge.

What happens next

BFAR filed a motion for reconsideration on August 14, 2026, so the ruling is not yet final in the sense of being beyond revision, and it is possible the Court will clarify or modify aspects of it. The decision also does not invalidate the Fisheries Code or RA 10654, nor does it bar vessel monitoring as such — it invalidates this order, on this record. A properly grounded issuance, covering all vessels, resting on current and disclosed studies, and staying within the statutory definition of monitoring, would be a different case.

There is genuine tension to acknowledge here. IUU fishing is a serious problem for Philippine food security and for the country's standing with trading partners that condition market access on IUU controls, and the international trend runs toward more vessel monitoring, not less. The Court's answer is not that monitoring is impermissible but that this particular instrument was not shown to work, exceeded its statutory basis, and was adopted without the process the law requires.

What individuals should know

If you operate a commercial fishing vessel, the immediate effect is that the VMS and ERS requirements imposed by FAO No. 266 have been declared unconstitutional. Watch the motion for reconsideration before making operational decisions, and note that other obligations under RA 8550 as amended — licensing, catch reporting, area restrictions, and the requirements of FAO No. 260 within its own scope — are unaffected by this ruling.

If you are a business in any regulated sector, treat this as a usable precedent. Three questions it authorizes you to ask of a new agency issuance: does the enabling statute actually authorize what the rule requires, read against the statute's own definitions; is there evidence that the measure achieves its stated purpose, or does it merely duplicate existing reporting; and was the consultation genuine — were you told what studies the agency relied on, allowed to nominate experts, and given a real opportunity to comment before the agency committed itself?

And note the privacy dimension, which extends past fisheries. The Court accepted that continuous location data is proprietary business information — that transmitting a vessel's position around the clock reveals fishing grounds, a trade secret with commercial value. The same reasoning applies to any mandate for continuous geolocation of vehicles, equipment, or personnel by a regulator, and it sits alongside the obligations of the Data Privacy Act.
