Supreme Court Overrules Chevron; Courts Must Determine “Best” Meaning of Statutes Without Deference

Here's a teaser from this Client Update: "The Supreme Court of the United States has overruled Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc. For 40 years, if an agency was interpreting an "ambiguous" provision of a statute it administers, the agency's interpretation need not be the best or most reasonable interpretation. Agencies were free to change their minds, and in some instances, important questions of public policy would swing back and forth with changing presidential administrations.

After Loper Bright Enterprises, et. al. v. Raimondo, et. al., deference to merely reasonable agency interpretations is over, as is agency flip-flopping rooted in "Chevron deference." The long-term result will be to empower courts and regulatory challengers at the expense of executive branch agencies, and the change may be significant in some places."
