The U.S. Supreme Court recently overturned the long-standing Chevron deference, established in 1984, which required courts to defer to agency interpretations of ambiguous statutes. This decision diminishes federal agencies' powers, impacting environmental regulations and sparking regulatory disputes. The ruling in Loper Bright Enterprises v. Raimondo, favoring private fisheries over the Department of Commerce, exemplified this shift, returning power from agencies to the courts. The decision is seen as a victory for conservatives and businesses, while environmental groups are divided on its implications. The demise of Chevron marks a significant change in how laws are interpreted, moving away from agency dominance towards a more balanced system involving the courts and Congress.
