Supreme Court Leaves Maine Lobster-Boat GPS Tracker Rule Intact
By Drooid · · How we work
Core Event
The U.S. Supreme Court declined to grant certiorari to Frank Thompson’s challenge of Maine’s 2023 rule that requires every federally licensed lobster vessel to carry a GPS tracker that records location every minute while underway and every six hours while docked. The denial leaves in place the First Circuit’s affirmation that the tracking mandate does not violate the Fourth Amendment because lobstering is deemed a “closely regulated” industry.
Background & Context
Maine’s Department of Marine Resources (DMR) instituted the tracking requirement to aid in the management of the North Atlantic right whale, monitor lobster populations, and support long-term fishery sustainability. The rule applies to roughly 1,200 licensed lobstermen in the state. Under the regulation, a small electronic box—often described by opponents as a “black box”—remains on the vessel at all times, even during personal trips.
Key Figures & Groups
- Frank Thompson — fifth-generation lobsterman from Vinalhaven, owner of Fox Island Lobster Company.
- Matthew Gilliam — attorney with the Pacific Legal Foundation representing Thompson and other plaintiffs.
- Carl Wilson — Commissioner, Maine Department of Marine Resources.
- Sarah Shahabi — associate attorney, Conservation Law Foundation (CLF).
- American Farm Bureau Federation (AFBF) — agricultural group that filed an amicus brief supporting the challenge.
Data & Statistics
- Approximately 1,200 Maine lobstermen hold the federal permits that trigger the GPS requirement.
- The device logs the boat’s position once per minute while moving and every six hours while docked.
- The rule was implemented in December 2023.
Criticism & Opposition
Thompson echoed this view, asserting that the rule turns his boat into a “government-issued 24/7 ankle bracelet” and threatens a way of life passed down through generations. The AFBF warned that the First Circuit’s reasoning could erode Fourth Amendment protections for farmers, ranchers, and other regulated sectors.
Conflicting Reports & Gaps
Legal analysts note a split among federal appellate courts regarding the breadth of the “closely regulated industry” exception. While the First Circuit applied the doctrine to lobstering, other circuits have taken narrower approaches, leaving uncertainty about how future cases involving different industries might be decided.
