In Chevron USA v Natural Resources Defense Council, 467 U.S. 837 (1984), the U.S. Supreme Court established the standard of judicial review that courts should apply when evaluating an agency’s construction of a statute which it administers. Under the Court’s decision, “if Congress has not directly spoken to the precise question at issue, the question for the court is whether the agency’s answer is based on a permissible construction of the statute.”
