My favorite law casebook ever. The material is HARD (think of it as the bastard child of constitutional law and civil procedure), but very interesting. Subject matter jurisdiction, Article I and III courts, federal review of state decisions, military tribunals, federal questions, McCardle problems, 1983 actions, implied remedies/causes of action are all covered in an effective manner. The post-case notes are among the most thought provoking I've ever seen in a casebook.
