SEABROOK, N.H. (AP) — The U.S. Supreme Court has denied a petition filed by a New England fishing group over the cost of at-sea monitors.

Monitors are workers who gather data that inform fishing regulations. The government shifted the cost of paying for them to fishermen in some Northeast fisheries in 2016.

New Hampshire cod fisherman David Goethel led the lawsuit. He says the cost shift adds hundreds of dollars to the daily cost of fishing and is driving people out of business.

Attorneys for Goethel say on Monday that they’re disappointed the Supreme Court has declined to hear the case. They say they’ll look for new ways to challenge the cost shift, which they contend is unlawful.

The suit named the U.S. Department of Commerce, which includes the National Oceanic and Atmospheric Administration.
