The US Supreme Court today overturned the 40-year-old Chevron precedent in a ruling that limits the regulatory authority of federal agencies. The 6-3 decision in Loper Bright Enterprises v. Raimondo will make it harder for agencies such as the Federal Communications Commission and Environmental Protection Agency to issue regulations without explicit authorization from Congress.

Chief Justice John Roberts delivered the opinion of the court and was joined by Clarence Thomas, Samuel Alito, Neil Gorsuch, Brett Kavanaugh, and Amy Coney Barrett. Justice Elena Kagan filed a dissenting opinion that was joined by Sonia Sotomayor and Ketanji Brown Jackson.
