Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837 (1984), was a landmark case in which the Supreme Court set forth the legal test for determining whether courts should grant deference to a government agency's interpretation of a statute that it administers. Until it was overturned by
Loper Bright Enterprises v. Raimondo, 603 U.S. ___ (2024),
Chevron was the Court's clearest articulation of the doctrine of "administrative deference" to the point that the Court itself used the phrase "
Chevron deference" in more recent cases. The Court, in an opinion by Justice
John Paul Stevens, upheld the EPA's interpretation. A two-part analysis was born from the
Chevron decision (called the "
Chevron two-step test") in which a reviewing court first determined whether Congress has directly spoken to the precise question at issue. If the intent of Congress was clear, that was the end of the matter because the court and the agency must give effect to the unambiguously expressed intent of Congress. If, however, the court determined that Congress had not directly addressed the precise question at issue, and the statute was silent or ambiguous with respect to the specific issue, the court did not simply impose its own construction on the statute but determined whether the agency's answer was based on a permissible construction of the statute. Although
Loper overturned
Chevron, it did not overturn
Skidmore and left the
Skidmore deference as a means for agency interpretation to be respected in judicial overview.
Christensen v. Harris County, 529 U.S. 576 (2000), is a Supreme Court case holding that a county's policy of requiring employees to schedule time off to avoid accruing time off was not prohibited by the
Fair Labor Standards Act. The Court held that an opinion letter from the Department of Labor, stating that an employer had to get the employee to agree first before it required the employee to schedule time off, did not receive
Chevron deference but should receive the less deferential standard of
Skidmore v. Swift & Co. The majority attempted to draw a bright line between formal agency documents (such as legislative rules) and less formal ones (such as opinion letters). Therefore, the opinion letter of the Department of Labor was not binding on the court. The court went on to state nothing in the FLSA that prohibited the forced use of compensation time. Justice Thomas delivered the 6–3 decision of the court in favor of Harris County and ruled that an agency's interpretation of a statute, announced in more informal agency papers (such as an opinion letter) is entitled to
Skidmore deference, not
Chevron deference. The continuing vitality of
Skidmore deference was questioned by Justice Scalia but is still used when agency actions do not carry the force of law.
Justice Scalia, in his concurrence in
Christensen v. Harris County, argued that
Skidmore has no place since
Chevron. However, the majority in
Christensen held that an agency's interpretation of a statute, announced in more informal agency papers (such as an opinion letter), is entitled to
Skidmore deference, not
Chevron deference.
United States v. Mead Corp., 533 U.S. 218 (2001), explicitly reaffirms
Skidmore and reiterates deference to agency interpretations that do not have statutory authority resulting from a rulemaking process are based on "the agency's care, its consistency, formality, and relative expertness, and to the persuasiveness of the agency's position." ==See also==
