How a lobsterman's privacy fight reached SCOTUS — and could ripple far beyond the water: 'Ain't over yet'

One Maine lobsterman isn’t ready to give up after the Supreme Court declined to hear his challenge to a GPS vessel-tracking requirement Monday, fearing it threatens a way of life passed down for generations and could ripple across other industries.

For decades, fifth-generation lobsterman Frank Thompson has driven his boat from Vinalhaven, a small island off the Maine coast, into deeper waters to set traps and haul in lobsters.

Now, he says a GPS tracking mandate has turned his boat into a government-issued 24/7 "ankle bracelet," sparking a years-long legal battle over constant surveillance and Fourth Amendment rights.

"This is totally against the Fourth Amendment , and somebody's got to hear it one way or another," Thompson told Fox News Digital.

"This black box that they're putting aboard the boat is not legal, in my mind, and I'm not a criminal." Thompson, who also owns Fox Island Lobster Company with his wife and two sons, was out fishing earlier this month when one of his sons texted him, letting him know the Supreme Court had declined his petition to hear the case and left in place a First Circuit ruling that said the GPS tracking requirement did not violate the Fourth Amendment because lobstering is a closely regulated industry.

The mandate, requiring a small electronic box to be installed aboard federally licensed lobster boats in Maine, has flipped Thompson’s life upside down, he said.

According to the Maine Department of Marine Resources (Maine DMR), the devices collect a boat’s location once per minute while moving and every six hours while docked.

The tracking doesn’t stop there, Thompson said, with the device collecting data even during personal trips, a key concern in his case.

Whether Thompson is traveling back to the mainland or having a family picnic, he said the device gives him "a creepy feeling" about who has his information and who is possibly watching.

"Freedom is gone.

What else can they do to us?" he said.

Thompson said there is even more at stake.

He described how his first boat ride happened two days after he was born and how his sons and grandchildren are following in his footsteps today.
