After nearly 40 years and more than 18,000 judicial opinions in which it was applied, the Chevron doctrine was overruled by the U.S. Supreme Court in Loper Bright Enterprises v. Raimondo. A few days later, the Supreme Court held that the statute of limitations to challenge an agency action under the Administrative Procedure Act (APA) does not begin to run until a plaintiff is injured by final agency action. Together, these two rulings will affect a wide range of regulated agencies for years to come.
