From all this it is entirely clear that the President had the legal power to remove Mr. Stanton, no matter whether the Tenure-of-Office Act was constitutional or not, simply because his case was excepted by the proviso in the first article in the Act from the operation of the Act, and was left to the operation of the laws in existence at the time the Act was passed. There is little question now that that Act was not in accordance with a fair interpretation of the Constitution, but it was not at all necessary to hold that view in order to clear the President of the accusation of having violated the Constitution and the laws of the land. {186} The law in reference to the _ad interim_ appointment, or designation, of General Thomas was equally plain to the impartial eye. The Constitution provides only for vacancies that may happen during the recess of the Senate, and empowers the President to fill all such by granting commissions which shall expire at the end of its next session. By an act of May 8th, 1792, Congress empowered the President, in case of the death, sickness, or absence from the seat of government, of the Secretary of State, the Secretary of the Treasury, or the Secretary of War, whether these events should occur during a session, or a recess, of the Senate, "to authorize any person or persons, at his discretion, to perform the duties of the said respective offices until a successor be appointed, or until such absence or inability by sickness should cease." Another act of Congress of February 13th, 1795, empowered the President, in case of vacancy from any cause in the offices of Secretary of State, Secretary of the Treasury, or Secretary of War, happening either during a recess or a session of the Senate, "to authorize any person or persons, at his discretion, to perform the duties of the said respective offices until a successor be appointed or such vacancy be filled," provided, however, that no one vacancy should be supplied in that manner for a longer time than six months.
