The authors of this casebook are committed to reflect fully the dynamism, controversy, and excitement that characterize contemporary Constitutional Law. While generally striving for brevity, the authors lightly edit cases where the Court appears to be embarking on a new doctrinal course so that sharply different constitutional philosophies are fully and fairly presented. Features of the new Eighth Edition include: • Hamdan v. Rumsfeld -- the legality of the use of military commissions by the Executive Branch. • Boumediene v. Bush -- alien enemy combatants detained at Guantanamo and ""the constitutional privilege of habeas corpus."" • District of Columbia v. Heller and McDonald v. City of Chicago -- the personal right to keep and bear arms vis-a-vis federal and state governments. • Gonzales v. Carhart -- limiting the abortion right. • United Haulers Association, Inc. v. Oneida-Herkimer Solid Waste Management Authority -- state regulation of solid waste and the dormant Commerce Clause • Parents Involved in Community Schools v. Seattle School District No. 1 -- affirmative action in the public schools. In the area of free expression, among the many cases featured are: • Holder v.

Frederick -- student speech in the high schools. • Garcetti v. Ceballos -- free expression rights of government employees. • United States v.
