Designed for students in advanced courses and newly revised, this book explains the leading principles of federal jurisdiction. It covers such landmarks as Marbury v. Madison and Bivens v. Six Unknown Named Agents and the rules that govern original and appellate jurisdiction, justiciability and abstention, federal habeas corpus, and sovereign immunity. It discusses the enemy combatant cases, culminating in Boumediene, and recent Supreme Court decisions on such diverse issues as the legal foundation of the Ex parte Young action, the limits of federal ingredient jurisdiction, the demise of prudential standing, and the jurisdictional nuances of consumer class action litigation. Perhaps most important, the book provides students with a sense of the argumentative possibilities available to lawyers and jurists working within the federal courts' tradition.
