The Administrative Procedure Act (APA) is a federal law that establishes important procedures for federal agency rulemaking and adjudication and provides standards for judicial review of many agency actions. The APA requires notice-and-comment procedures for many rules, subject to statutory exceptions and other requirements.

Example: EPA’s 2024 rule revising the national ambient air quality standards for fine particulate matter followed a federal rulemaking process that included public comments.

Common misconception: The APA gives agencies unlimited authority to regulate. It sets procedures and review standards; the underlying authority to act must still come from the Constitution or a statute.
