Designed for students in advanced courses, this book explains the leading principles of federal jurisdiction. It covers Marbury v. Madison and Bivens v. Six Unknown Named Agents, as well as rules governing 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 the Antiterrorism and Effective Death Penalty Act, federal ingredient jurisdiction, complete preemption removal, and supplemental jurisdiction. The book also provides students with a sense of the argumentative possibilities available to lawyers and jurists working within the federal courts' tradition.
