The Supreme Court declined on Monday to hear the case of Frank Thompson, a fifth-generation Maine lobsterman who challenged a state mandate requiring GPS tracking devices on his fishing vessel. The decision leaves in place a ruling by the U.S. Court of Appeals for the First Circuit, which held that the tracking requirement did not violate the Fourth Amendment because lobstering is a closely regulated industry. Thompson and his legal team have indicated that the fight over privacy rights in regulated industries may continue in other venues.
The mandate, implemented by the Maine Department of Marine Resources in 2023, requires federally licensed lobster boats to carry small electronic boxes that collect location data once per minute while moving and every six hours while docked. State officials and conservation groups argue the technology is essential for protecting endangered North Atlantic right whales and monitoring lobster populations. Thompson, who operates Fox Island Lobster Company, contends the devices function as government-issued surveillance tools that infringe on his personal liberty and professional independence.
What the Left Is Saying
Conservationists and state regulators have supported the tracking mandate as a necessary measure for environmental protection and sustainable fisheries management. The Conservation Law Foundation, which filed an amicus brief in support of the requirement during the First Circuit appeal, praised the Supreme Court’s decision to decline review. A representative for the foundation stated that the ruling is a valuable step toward appropriately managing shared natural resources and protecting endangered species from vessel strikes.
Proponents of the mandate argue that the intrusion on privacy is minimal compared to the public benefit of preserving the ecosystem. They point to the biological data collected by the devices, which helps scientists understand lobster migration patterns and right whale habitats. For these groups, the legal challenge represents a pushback against science-based regulation that is critical for the long-term viability of the lobster industry and marine biodiversity.
What the Right Is Saying
Frank Thompson and his attorney, Matthew Gilliam of the Pacific Legal Foundation, frame the issue as a fundamental violation of Fourth Amendment rights. Gilliam argued that the trackers are a condition of earning a living, making the mandatory installation a forced trespass and an unreasonable search and seizure without a warrant. "That forced trespass was a violation of the Fourth Amendment because it's an unreasonable search and seizure," Gilliam stated.
Thompson described the devices as turning his boat into a "government-issued 24/7 ankle bracelet," noting that the tracking continues during personal trips, such as family outings. He expressed skepticism about the government's stated reasons for the mandate, saying, "They're bringing it up because it's for the whales. Well, the government's lying through their teeth like they always do, and I'm not a criminal." Thompson maintains that the surveillance erodes the independence of small business owners and warns that similar tracking could expand to other industries, such as agriculture.
What the Numbers Show
The Maine Department of Marine Resources implemented the rule in 2023 at the direction of the Atlantic States Marine Fisheries Commission. The devices collect location data at two intervals: once per minute when the vessel is moving and every six hours when docked. The legal battle began shortly after the mandate took effect, when Thompson and four other lobstermen filed a federal lawsuit claiming non-consensual tracking. A federal judge dismissed the case, and the First Circuit upheld the dismissal, citing the exception for closely regulated industries. The American Farm Bureau Federation filed an amicus brief supporting Thompson’s challenge, arguing that the lower court’s reasoning could weaken Fourth Amendment protections for farmers and ranchers.
The Bottom Line
The Supreme Court’s refusal to hear the case solidifies the precedent that closely regulated industries may be subject to warrantless surveillance requirements if deemed necessary for public safety or conservation. However, the issue remains unresolved for broader privacy rights advocates. Thompson has indicated he is not finished fighting, stating, "I just told myself, I said, ‘Well, it ain't over yet.’" The American Farm Bureau Federation’s involvement suggests that the debate over digital privacy in regulated sectors may extend to agriculture and other industries in future legislative or legal proceedings. Observers will watch for potential state-level legislative responses or new legal challenges that test the boundaries of the "closely regulated industry" exception.
