place the executive power in the same hands, we may readily simplify government. We may easily bring it to the simplest of all possible forms, a pure despotism. But a separation of departments, so far as practicable, and the preservation of clear lines of division between them, is the fundamental idea in the creation of all our constitutions; and, doubtless, the continuance of regulated liberty depends on maintaining these boundaries." Each department is supreme within its own constitutionally prescribed limits, and the Supreme Court is made the umpire for the definition of the limits and the protection of the rights of all. Neither Congress, nor the Executive, are authorized to determine the constitutionality and therefore the validity of their acts, or the limits of their jurisdiction under the Constitution, but the Supreme Court is so authorized, and it is the umpire before which all differences in that regard must be determined. It is the tribunal of last resort, save the people themselves, before whom both Senate and House, and the Executive, must bow, and its decision is final in the interpretation of the Constitution. A due regard, therefore, for the interpretation of law and the division of powers thus established, constitutes the great safeguard upon which the harmonious and successful operation of our political system depends. On its religious observance rests, primarily, the preservation of our free institutions and the perpetuation of our peculiar system of popular government. That quality of co-ordination--of the equality of the several Departments as adjusted by the Organic Act--constitutes the balance wheel of our political system. The logical effect of the doctrines promulgated by the House of Representatives in that regard, and re-echoed on the floor of the Senate, in the press and on the stump throughout the North, were therefore not only revolutionary, but destructive. To have removed the President upon accusations in reality based upon partisan and personal--not amounting even to substantial political differences--would have been the establishment of a precedent of the most dangerous character. In a large sense, the American system of politics and of government was on trial, quite as much as was Andrew Johnson. The extreme element of American politics was in absolute control in the House of Representatives, and practically so, in the Senate. The impeachment and removal of the President on unsubstantiated, or even remotely doubtful charges, simply: because of a disagreement between himself and Congress as to the method of treating a great public emergency, would have introduced a new and destructive practice into our political system.
