Loper Bright Enterprises v. RaimondoThis is a consolidated opinion of two cases that were argued this term.  Both of them bring into question rules promulgated by the National Marine Fisheries Service under the Magnuson-Stevens Act -- which applies the Adminsitrative Procedures Act.  The only question on appeal is whether Chevron is still good law.  Chief Justice Roberts, writing for the 6-3 Court, holds that "The Administrative Procedure Act requires courts to exercise their independent judgment in deciding whether an agency has acted within its statutory authority, and courts may not defer to an agency interpretation of the law simply because a statute is ambiguous; Chevron is overruled."
