Background
Maui and Hector’s Dolphin Defenders NZ Inc., a New Zealand environmental nonprofit, challenged the National Marine Fisheries Service’s 2026 comparability findings regarding New Zealand’s trawl and set net fisheries. Under the Marine Mammal Protection Act (“MMPA”), the United States must ban imports of fish caught with commercial fishing technology that results in incidental death or serious injury to marine mammals in excess of U.S. standards. NMFS issued findings in March 2026 determining that New Zealand’s regulatory program was comparable in effectiveness to U.S. protections.
This was the third iteration of comparability findings for the same fisheries. In Maui I (2025), the court found prior 2024 comparability findings arbitrary and unsupported by substantial evidence. After NMFS issued 2025 findings, the prior case was dismissed as moot. Plaintiff now challenges the 2026 findings as arbitrary and capricious and seeks to compel an import ban under the Administrative Procedure Act.
Defendants moved to dismiss for lack of standing and subject-matter jurisdiction. Plaintiff simultaneously moved for a preliminary injunction to immediately ban imports pending judicial review of the comparability findings.
The Court’s Holding
The court denied both motions, allowing the case to proceed on the merits but withholding immediate relief. On standing, the court found Plaintiff had adequately alleged Article III injury: members’ aesthetic, recreational, and cultural interests in dolphin populations are harmed by fishing practices that the government fails to restrict. The court rejected Defendants’ arguments that causation was too attenuated. Applying common-sense economic principles, an import ban would eliminate U.S. demand for New Zealand seafood, reducing economic incentives for the contested fisheries and predictably influencing New Zealand’s regulatory decisions. The court noted evidence that prior import bans had measurably affected export revenue.
On redressability, the court held that Congress explicitly determined in the MMPA that import embargoes are an effective remedy for foreign marine mammal harm. The court emphasized that “[t]he MMPA addresses not only the killing of marine mammals by Americans but also the importation of them. This reflects a congressional decision that denial of import privileges is an effective method of protecting marine mammals in other parts of the world.” The Government of New Zealand’s ongoing intervention in the litigation supported the inference that it views import restrictions as consequential.
On the preliminary injunction, the court declined to grant immediate relief despite denying the motion to dismiss. The MMPA requires foreign regulatory programs to meet a “Zero Mortality Rate Goal”—limiting incidental bycatch to below 10 percent of the Potential Biological Removal level. The court examined whether New Zealand’s alternative metric (Population Sustainability Threshold) and actual bycatch rates (0.056 Māui dolphins and 8.8 Hector’s dolphins annually, against limits of approximately 18 and 126 respectively) satisfied this standard, finding the record analysis ongoing.
Key Takeaways
- Foreign-based environmental organizations can establish standing to challenge MMPA comparability findings by alleging injury to members’ interests in international marine mammal populations, provided causation and redressability satisfy Article III requirements.
- Courts will apply straightforward economic reasoning—supply-and-demand logic—to find causation where import restrictions would reduce foreign demand for contested fishery products, even absent direct U.S. regulatory authority over foreign fisheries.
- Congressional declarations in statutes about remedy effectiveness (here, that import embargoes protect marine mammals) inform redressability analysis; courts need not defer to executive assertions that diplomatic or political obstacles make judicial relief impracticable.
- Winning on standing and jurisdiction does not guarantee preliminary injunction relief; courts separately evaluate likelihood of success on the underlying merits using administrative law standards.
Why It Matters
This decision clarifies that the MMPA’s import-restriction regime is judicially enforceable against government inaction, at least where a plaintiff can establish Article III standing. It rejects a formalist barrier—that U.S. courts cannot redress foreign conduct—in favor of practical economic analysis. Environmental groups can leverage import restrictions as a substantive remedy for overseas marine mammal harm, not merely symbolic criticism.
The repeated cycling of comparability findings (2024 findings overturned, 2025 findings issued and mooted, 2026 findings now challenged) signals ongoing legal and policy tension over how much marine mammal protection New Zealand must implement to maintain U.S. market access. The court’s willingness to proceed on the merits, despite the government’s repeated reissuance of findings, suggests judicial skepticism of any mootness or finality doctrine that would shelter comparability determinations from review.
