This treatise offers a fully updated and in-depth analysis of U.S. administrative law, with a focus on areas currently experiencing significant development in the Supreme Court and federal courts of appeals. Key topics include Congress’s delegation of legislative authority to agencies, deference to agency interpretations, the “major questions” doctrine, modern due process concerns, and the presidential appointments power.

The book’s primary goals are to evaluate and explain the current state of core administrative law doctrines, situate them within their historical context, and highlight emerging trends that illuminate how these doctrines may continue to evolve. Designed for practitioners, scholars, and students, it provides a comprehensive resource for understanding both the foundational principles and the dynamic developments shaping administrative law today.
