This book is the 2026–2027 Supplement to Administrative Law: A Lifecycle Approach, Second Edition, by Dean Jamelle C. Sharpe.

Administrative law has been transformed since the Second Edition published in 2023. In a rapid sequence of landmark rulings, the Roberts Court has overruled Chevron and Humphrey's Executor, narrowed agencies' power to adjudicate their own enforcement actions, and cleared the way for the President to remove the leaders of independent agencies at will. The Trump Administration has pressed that authority further still, reaching past agency heads to assert control over the career civil service itself. This 2026–2027 Supplement brings students fully up to date with these developments — through excerpts of the critical cases themselves and a comprehensive overview of how the Roberts Court and the Trump Administration have reshaped administrative law, agency authority, and the federal workforce.

The Supplement's new material spans the casebook from its early chapters on the administrative state's origins through to its chapters on judicial review, agency adjudication, removal, and the civil service — while leaving the casebook's signature three-stage lifecycle organization fully intact.
