The authors, recognized authorities for over a third of a century, provide succinct and authoritative coverage of the major principles in modern American constitutional law. This book is a shortened version based on the authors' hornbook (popular with students) and their six-volume treatise (popular with judges, practitioners, and scholars). It analyzes the constitutional issues studied today, and discusses the origins of judicial review and federal jurisdiction, federal commerce and spending powers, state powers in light of the dormant Commerce Clause, the war power, freedom of speech and religion, equal protection, due process, and other important individual rights and liberties. This book is completely up to date and includes all major Supreme Court cases through February, 2016, including the ground breaking First Amendment decisions of the Roberts' Court.
