The Supreme Court overruled the Chevron doctrine in Loper Bright Enterprises v. Raimondo. Federal courts must now exercise their own independent judgment when deciding what an ambiguous statute means. An agency’s interpretation may still be persuasive, especially when Congress delegated policymaking authority, but it no longer receives controlling deference simply because the statute is ambiguous.
What Chevron required
Under Chevron U.S.A. Inc. v. Natural Resources Defense Council, courts generally asked whether Congress had directly answered the statutory question. If the statute was ambiguous, a court often accepted a reasonable agency interpretation even if the court might have preferred another reading.
Why the doctrine mattered
Chevron shaped disputes involving environmental rules, immigration, labor, telecommunications, healthcare, finance, and many other regulated fields. Supporters argued that agencies have expertise and political accountability. Critics argued that deference allowed executive agencies to exercise interpretive power that belongs to courts and made legal obligations change with administrations.
What Loper Bright decided
In 2024, the Supreme Court held that Chevron could not be reconciled with the Administrative Procedure Act. The Court emphasized 5 U.S.C. § 706, which directs reviewing courts to decide all relevant questions of law and interpret statutory provisions.

The decision does not mean agencies receive no respect. Courts may consider agency reasoning for its power to persuade, and statutes may expressly authorize agencies to fill gaps or make policy choices. The key change is that ambiguity alone no longer triggers mandatory Chevron deference.
What happens to older Chevron decisions
The Court stated that overruling Chevron did not automatically reopen every prior judgment that relied on the doctrine. Ordinary principles of precedent and finality still apply. New and pending cases, however, use the independent-judgment approach described in Loper Bright.
Effects on agencies and regulated businesses
- Agencies need stronger textual and statutory support for major interpretations.
- Businesses may have more room to challenge regulations, but litigation outcomes can vary among courts.
- Congress faces greater pressure to draft clear delegations and definitions.
- Regulated parties should track judicial decisions, not only agency guidance.

Business Law 101 takeaway: after Loper Bright, statutory text, delegated authority, and judicial interpretation matter more than a general presumption in favor of an agency’s reasonable view.
