Plain-English summary
Rules courts must independently decide if agencies acted within statutory authority, curbing Chevron déf.
In Loper Bright v. Raimondo (22-451), the Court held that courts must exercise independent judgment when deciding whether an agency acted within statutory authority and cannot automatically defer to the agency under Chevron. The decision vacated and remanded the D.C. Circuit ruling and reduces automatic judicial deference to agency interpretations of law.
Why this matters
The ruling reduces the power of federal agencies to have courts automatically accept their readings of ambiguous statutes. That shifts more authority to judges to interpret laws themselves and can affect how federal rules and enforcement actions are reviewed and upheld across many areas of federal regulation.
Who may feel it
- Federal administrative agencies (EPA, Commerce, FCC, etc.)
- Regulated industries (businesses affected by agency rules)
- Individuals challenging or defending agency actions
- Lower federal courts and judges
Key questions
- When a statute is ambiguous, should courts defer to a federal agency’s interpretation under Chevron deference?
- What standard must courts apply when reviewing whether an agency acted within the scope of its statutory authority under the APA?
