Law of the United States:

New York, Illinois, and California are the most significant states that have not adopted the FRCP. Furthermore, all three states continue to maintain most of their civil procedure laws in the form of codified statutes enacted by the state legislature, as opposed to court rules promulgated by the state supreme court, on the ground that the latter are undemocratic. But certain key portions of their civil procedure laws have been modified by their legislatures to bring them closer to federal civil procedure.
