A federal judge ruled Tuesday that Maui County must face trial over claims its streetlights disorient and kill three species of protected Hawaiian seabirds, setting up a legal battle that could force costly changes to public infrastructure across the island.
U.S. District Judge Micah Smith denied summary judgment motions from both sides, finding factual disputes too significant for him to resolve without a full trial. The Conservation Council for Hawaii and American Bird Conservancy filed the lawsuit in November 2024, accusing the county of violating the Endangered Species Act.
How Streetlights Allegedly Kill Seabirds
The conservation groups claim Maui’s streetlights pull endangered Hawaiian petrels, Newell’s shearwaters, and a third protected species off their nightly flight paths from mountain nests to the ocean. Disoriented birds circle artificial lights until exhausted, then fall to the ground where they face predators, starvation, or vehicle strikes.
Maui County disputes the science behind these claims, arguing the evidence doesn’t prove streetlights cause seabird deaths. Judge Smith acknowledged both sides present competing expert testimony and conflicting interpretations of available data.
What Trial Means for Taxpayers
“Credibility determinations, the weighing of the evidence, and the drawing of legitimate inferences from the facts are jury functions, not those of a judge ruling on a motion for summary judgment,” Smith wrote in his order.
If the county loses at trial, it could face injunctions requiring streetlight modifications or replacements across Maui—potentially costing millions in taxpayer dollars. The lawsuit targets existing municipal lighting infrastructure, not new development projects.
The Endangered Species Act carries strict liability provisions. Unlike typical negligence cases, violators can face penalties even without intent to harm protected species. This legal framework has led to expensive settlements in similar cases involving federal land management and utility companies.
Trial dates have not yet been scheduled. Both sides will now prepare to present their scientific evidence and expert witnesses before Judge Smith in what’s expected to be a bench trial rather than a jury trial.
Key Points
- Judge refused to dismiss lawsuit claiming Maui streetlights kill endangered seabirds by disorienting them during nightly flights
- County disputes the science but must now defend its lighting infrastructure at trial under Endangered Species Act strict liability standards
- Loss could force costly streetlight modifications across the island, with taxpayers covering the bill for municipal infrastructure changes
