Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc.

Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc. is a landmark U.S. Supreme Court case from 1984 that established a legal principle known as "Chevron deference." This principle grants federal agencies the authority to interpret ambiguous statutes they administer. If a law is not clear, courts should defer to the agency's interpretation as long as it is reasonable. The decision affirmed the federal government’s ability to make regulatory decisions, particularly in environmental law, balancing the expertise of agencies with the judiciary's role in overseeing these interpretations.
