It will readily suggest itself to anyone who reflects upon the abilities and the learning in the law which distinguish so many Senators that besides the reason assigned in the Federalist there must have been still another for the provision requiring the Chief Justice to preside in the court of impeachment.  Under the Constitution, in case of a vacancy in the office of President, the Vice-President succeeds, and it was doubtless thought prudent and befitting that the next in succession should not preside in a proceeding through which a vacancy might be created.

It is not doubted that the Senate, while sitting in its ordinary capacity, must necessarily receive from the House of Representatives some notice of its intention to impeach the President at its bar, but it does not seem to me an unwarranted opinion, in view of this constitutional provision, that the organization of the Senate as a court of impeachment, under the Constitution, should precede the actual announcement of the impeachment on the part of the House.

And it may perhaps be thought a still less unwarranted opinion that articles of impeachment should only be presented to a court of impeachment; that no summons or other process should issue except from the organized court, and that rules for the government of the proceedings of such a court should be framed only by the court itself.

I have found myself unable to come to any other conclusions than these.  I can assign no reason for requiring the Senate to organize as a court under any other than its ordinary presiding officer for the latter proceedings upon an impeachment of the President which does not seem to me to apply equally to the earlier.

I am informed that the Senate has proceeded upon other views, and it is not my purpose to contest what its superior wisdom may have directed.

All good citizens will fervently pray that no occasion may ever arise when the grave proceedings now in progress will be cited as a precedent; but it is not impossible that such an occasion may come.

Inasmuch, therefore, as the Constitution has charged the Chief Justice with an important function in the trial of an impeachment of the President, it has seemed to me fitting and obligatory, where he is unable to concur in the views of the Senate concerning matters essential to the trial, that his respectful dissent should appear.

S.P.  CHASE,

Chief Justice of the United States.
