Good Governing: The Police Power in the American States is a deep historical and legal analysis of state police power, examining its origins in the founding period of the American public through the 20th century.

It explores police power's promise as a mechanism for implementing successful regulatory governance and tackling societal ills, while considering key structural issues like separation of powers and individual rights. This insightful book will shape understanding of the neglected state police power, a key part of constitutional governance in the U.S. This title is also available as Open Access on Cambridge Core. Explores the origins and functions of state police power and its connection to state constitutionalism and government regulation. Daniel B.
