Book excerpt: Receive complimentary lifetime digital access to the eBook with new print purchase. The hottest issue in state and local government today is preemption - the conflict between states and cities over authority in a wide range of sharply-contested areas, including gun control, minimum wages and family leave, anti-discrimination law, environmental protection, and sanctuary policies. This pathbreaking reader comes straight from the front-lines of that conflict. It presents and analyzes in concise form the most important preemption statutes and cases, along with commentary from the leading scholars in the field. Virtually all the material involves disputes that have emerged and decisions handed down in just the last two to three years. Designed for use in courses dealing with states and local governments as a supplement to existing casebooks or on its own, the reader will be a unique and invaluable resource for students, teachers, scholars, and anyone involved in preemption and state-local relations more broadly today.
