Chevron doctrine

Federal Chevron deference is dead. On June 28, 2024, in a 6-3 vote, the Supreme Court overturned the 40-year-old legal tenet that when a federal statute is silent or ambiguous about a particular regulatory issue, courts should defer to the implementing agency’s reasonable interpretation of the law. The reversal came in a ruling on two fishery regulation cases, Loper Bright Enterprises v. Raimondo and Relentless, Inc. v. Department of Commerce.

While courts and judges will vary, as a scholar in environmental law, I expect that the demise of Chevron deference will make it easier for federal judges to focus on the exact meaning of Congress’ individual words, rather than on Congress’ goals or the real-life wor...

The plaintiffs are challenging a nearly 40-year-old doctrine of federal administrative law, known as Chevron deference for the 1984 case in which it was set forth. This tenet provides that when a federal statu...
