Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc.
467 U.S. 837 (1984)
Supreme Court of the United States · 1984
Headnote
Created the two-step deference framework for agency interpretations of ambiguous statutes. Overruled by Loper Bright Enterprises v. Raimondo (2024).
Bench
Stevens, J.
Facts
The EPA's bubble-concept definition of 'stationary source' under the Clean Air Act was challenged as inconsistent with the statute.
Held
Where a statute is silent or ambiguous, a court must defer to a permissible agency construction. This framework no longer governs after Loper Bright.
Key passage
“If the statute is silent or ambiguous with respect to the specific issue, the question for the court is whether the agency's answer is based on a permissible construction of the statute.”
