 Two Supreme Court justices had previously disagreed on this question while riding circuit . In United States v. Ravara ( C.C.D. Pa . 1793 ) , an indictment for sending anonymous and threatening letters to a foreign minister with a view to extort money , Justice James Wilson argued that the circuit court could be given concurrent jurisdiction ; Justice James Iredell argued that it could not ; Judge Richard Peters , of the District of Pennsylvania , sided with Wilson , and the case continued .
