In this important book, fourteen of America's leading constitutional scholars assess the Supreme Court's performance expounding the animating principles of American constitutionalism. Essays devoted to fresh examination of the Supreme Court's jurisprudence with respect to the Necessary and Proper Clause, the Commerce Clause, federalism, the common law, international law and national sovereignty, separation of powers, fundamental rights, term limits, and constitutional criminal procedure. Other essays evaluate the work of the Court as 'republican school master,' analyzing how the Court has articulated and affected the American people's capacity for self-government, the principle of the rule of law, the historic burden of racial injustice, respect for limited constitutional government, and the civilizational distinction between liberty and license. The Supreme Court and American Constitutionalism will be of great value to students and scholars of American constitutional studies, constitutional law, and American government.
