Article 3, Section 2, Clause 3
James Madison to Edmund Randolph10 Mar. 1784Papers 8:4
2. The analogy of the laws throughout the States, and particularly the uniformity of trial by Juries of the vicinage, seem to obviate the capital objections agst. removal to the State where the offence is charged. In the instance of contiguous States a removal of the party accused from one to the other must often be a less grievance, than what happens within the same State when the place of residence & the place where the offence is laid are at distant extremities. The transportation to G. B. seems to have been reprobated on very different grounds: it would have deprived the accused of the privilege of trial by jury of the vicinage as well as of the use of his witnesses, and have exposed him to trial in a place where he was not even alledged to have ever made himself obnoxious to it; not to mention the danger of unfairness arising from the circumstances which produced the regulation.
