The issue of whether to overturn Chevron came before the court after two fishing companies ― Relentless and Loper Bright Enterprises ― challenged regulations imposed in 2020 by the National Marine Fisheries Service that required fishing boats to pay the salary of the federal inspectors who ride on them. Lawyers for the fishing companies argued that the court should not only overturn the regulations, but also eliminate the deference afforded to agencies to write such regulations by the court’s precedent in Chevron.
