The pending Supreme Court case, Loper Bright Enterprises v. Raimondo, involves fishing companies challenging the National Marine Fisheries Service (NMFS). They dispute NMFS's authority under the Magnuson-Stevens Act to require vessels to subsidize federal observers' salaries. The government defends NMFS's interpretation based on the Chevron Doctrine. The case questions whether the Supreme Court should limit or overrule this 1984 doctrine, which grants agencies deference in interpreting ambiguous statutes.
