This efficient, concise, and up-to-date Guide explains complex Administrative Law concepts in accessible language without sacrificing the nuance that distinguishes a superior exam performance from an average one. It follows a logical sequence of topics used by many professors in their classes, starting with the constitutional foundations of the administrative state, continuing through the procedural requirements for agency rulemaking and adjudication, then the rules governing judicial review of agency action, and concluding with agency control over information. The Third Edition discusses new and important administrative law cases critical to understanding the law today: SEC v. Jarkesy (2024) (construing Seventh Amendment limits on agency adjudication), Loper Bright v. Raimondo (2024) (rejecting "Chevron deference"), and Corner Post v. Federal Reserve (2024) (construing limitations periods for challenges to agency actions).
