The U.S. Supreme Court is currently considering its most consequential challenge to "the administrative state" in decades. In Loper Bright Enterprises v. Raimondo and Relentless v. Department of Commerce, the petitioners are fishermen who challenged a specific regulation concerning a requirement to host observers on herring fishing boats. Beyond that specific challenge, petitioners have also asked the court to overturn the seminal doctrine announced 40 years ago in Chevron v. Natural Resources Defense Council (1984).
