In a 6-3 ruling, the United States Supreme Court in Loper Bright Enterprises v. Raimondo,[1] overruled the longstanding precedent that federal courts were to defer to federal agencies’ interpretations of ambiguous federal laws. Thus, the nearly forty-year-old precedent established by Chevron v. Natural Resources Defense Council[2] is no more. Along similar lines, many states have either abandoned their Chevron-like review or adopted an approach like that in Loper Bright, which requires courts to exercise independent judgment when considering whether an agency has acted within its statutory authority.

Under the Chevron doctrine, a court was required to uphold a federal agency’s “permissible” interpretation under its purview if Congress had not directly addressed the question even when the reviewing court read the statute differently. This precedent provided broad authority to federal agencies. In Loper Bright, the Supreme Court rejected the notion that agencies are better suited to interpret the law after a group of family businesses that operate in the Atlantic herring fishery challenged a National Marine Fisheries Service rule that cost these family businesses nearly $710 per day. The Supreme Court emphasized that courts “must exercise their independent judgment in deciding whether an agency has acted within its statutory authority, as the APA requires.”[3]

Although Bright Loper does not explicitly apply to a state court’s review of state agency decisions, it supports the recent trend of the judicial branch applying independent review of executive agency interpretations of ambiguous statutes. In the last twenty years, nearly twelve states have adopted de novo review in place of affording deference to agency decisions. After Loper Bright, this trend is likely to continue.

For instance, in Florida, Louisiana, Mississippi, and Tennessee, state courts utilize de novo review when reviewing agency decisions construing the statutes under which they operate.[4] North Carolina, Pennsylvania, and Texas apply a “hybrid” approach, giving deference to agency interpretations depending on the interpretation of the agency.[5] For now, Alabama, Georgia, and South Carolina still employ deference to agency interpretations of the statutes they administer, but it will be interesting to see how the Bright Loper decision affects appellate court decisions in these states going forward.
