The necessity of a numerous court for the trial of impeachments, is equally dictated by the nature of the proceeding. This can never be tied down by such strict rules, either in the delineation of the offence by the prosecutors, or in the construction of it by the judges, as in common cases serve to limit the discretion of courts in favour of personal security. There will be no jury to stand between the judges, who are to pronounce the sentence of the law, and the party who is to receive or suffer it. The awful discretion which a court of impeachments must necessarily have, to doom to honour or to infamy the most confidential and the most distinguished characters of the community, forbids the commitment of the trust to a small number of persons.
These considerations seem alone sufficient to authorize a conclusion, that the supreme court would have been an improper substitute for the senate, as a court of impeachments. There remains a further consideration, which will not a little strengthen this conclusion. It is this: the punishment which may be the consequence of conviction upon impeachment, is not to terminate the chastisement of the offender. After having been sentenced to a perpetual ostracism from the esteem and confidence, and honours and emoluments of his country, he will still be liable to prosecution and punishment in the ordinary course of law. Would it be proper that the persons who had disposed of his fame, and his most valuable rights as a citizen, in one trial, should, in another trial, for the same offence, be also the disposers of his life and his fortune? Would there not be the greatest reason to apprehend, that error, in the first sentence, would be the parent of error in the second sentence? That the strong bias of one decision, would be apt to overrule the influence of any new lights which might be brought to vary the complexion of another decision? Those who know any thing of human nature, will not hesitate to answer these questions in the affirmative; and will be at no loss to perceive, that by making the same persons judges in both cases, those who might happen to be the objects of prosecution would, in a great measure, be deprived of the double
