On the contrary, the whole phraseology and sense of the resolution seem to be judicial. Its essence, true character, and only practical effect are to be found in the conduct which it charges upon the President and in the judgment which it pronounces on that conduct. The resolution, therefore, though discussed and adopted by the Senate in its legislative capacity, is in its office and in all its characteristics essentially judicial.
That the Senate possesses a high judicial power and that instances may occur in which the President of the United States will be amenable to it is undeniable; but under the provisions of the Constitution it would seem to be equally plain that neither the President nor any other officer can be rightfully subjected to the operation of the judicial power of the Senate except in the cases and under the forms prescribed by the Constitution.
The Constitution declares that “the President, Vice-President, and all civil officers of the United States shall be removed from office on impeachment for and conviction of treason, bribery, or other high crimes and misdemeanors;” that the House of Representatives “shall have the sole power of impeachment;” that the Senate “shall have the sole power to try all impeachments;” that “when sitting for that purpose they shall be on oath or affirmation;” that “when the President of the United States is tried the Chief Justice shall preside;” that “no person shall be convicted without the concurrence of two-thirds of the members present,” and that “judgment shall not extend further than to removal from office and disqualification to hold and enjoy any office of honor, trust, or profit under the United States.”
The resolution above quoted charges, in substance, that in certain proceedings relating to the public revenue the President has usurped authority and power not conferred upon him by the Constitution and laws, and that in doing so he violated both. Any such act constitutes a high crime—one of the highest, indeed, which the President can commit—a crime which justly exposes him to impeachment by the House of Representatives, and, upon due conviction, to removal from office and to the complete and immutable disfranchisement prescribed by the Constitution. The resolution, then, was in substance an impeachment of the President, and in its passage amounts to a declaration by a majority of the Senate that he is guilty of an impeachable offense. As such it is spread upon the journals of the Senate, published to the nation and to the world, made part of our enduring archives, and incorporated in the history of the age. The punishment of removal from office and future disqualification does not, it is true, follow this decision, nor would it have followed the like decision if the regular forms of proceeding had been pursued, because the requisite number did not concur in the result. But the moral influence of a solemn declaration by a majority of the Senate that the accused is guilty of the offense charged upon him has been as effectually secured as if the like declaration had been made upon an impeachment expressed in the same terms. Indeed, a greater practical effect has been gained, because the votes given for the resolution, though not sufficient to authorize a judgment of guilty on an impeachment, were numerous enough to carry that resolution.
