New York v. O'Neill
New York v. O'Neill, 359 U.S. 1 (1959), was a United States Supreme Court case in which the Court held that a Florida statute, established by the enactment of the Uniform Law to Secure the Attendance of Witnesses from Within or Without a State in Criminal Proceedings which established a procedure for a witness to be subpoened with the agreement of a court in a trial state and a court in the state of the witness, on its face does not violate the Privileges and Immunities Clause of Art.
