On June 28, the modern administrative state came to an end as the U.S. Supreme Court overruled its 1984 decision in Chevron U.S.A. Inc. v. Natural Resources Defense Council Inc.. This landmark decision had established the principle of judicial deference to administrative agencies’ interpretations of ambiguous statutes – a framework that significantly shaped regulatory practices for nearly four decades. The rollback of Chevron signifies a departure from the reliance on agency expertise and may lead to increased legal contention around statutory interpretations.
