In 1793 the protagonist of "executive power" was Alexander Hamilton, who appealed to the clause in defense of Washington's proclamation of neutrality, issued on the outbreak of war between France and Great Britain. Prompted by Jefferson to take up his pen and "cut him to pieces in face of public," Madison shifted position, and charged Hamilton with endeavoring to smuggle the prerogative of the King of Great Britain into the Constitution via the "executive power" clause.[39] Three years earlier Jefferson had himself written in an official opinion as Secretary of State: [The Executive branch of the government], "possessing the rights of self-government from nature, cannot be controlled in the exercise of them but by a law, passed in the forms of the Constitution".[40]
This time judicial endorsement of the broad conception of the executive power came early. In laying the foundation in Marbury v. Madison for the Court's claim of power to pass on the constitutionality of acts of Congress, Marshall said: "The government of the United States has been emphatically termed a government of laws and not of men".[41] Two pages along he added these words:
By the constitution of the United States, the President is invested with certain important political powers, in the exercise of which he is to use his own discretion, and is accountable only to his country in his political character, and to his own conscience. To aid him in the performance of these duties, he is authorized to appoint certain officers, who act by his authority and in conformity with his orders.
In such cases, their acts are his acts; and whatever opinion may be entertained of the manner in which executive discretion may be used, still there exists, and can exist, no power to control that discretion. The subjects are political. They respect the nation, not individual rights, and being entrusted to the executive, the decision of the executive is conclusive.[42]
From these words arises the doctrine of Political Questions, an escape clause from the trammels of judicial review for high executive officers in the performance of their discretionary duties. The doctrine was continued, even expanded, by Marshall's successor. In Luther v. Borden,[43] decided in 1849, the Court was invited to review the determination by the President that the existing government of Rhode Island was "republican" in form. It declined the invitation, holding that the decision of Congress and of the President as Congress's delegate was final in the matter, and bound the courts. Otherwise said Chief Justice Taney, the guarantee clause of the Constitution (Article IV, section 4) "is a guarantee of anarchy and not of order". But a year later the same Chief Justice, speaking again for the unanimous Court, did not hesitate to rule that the President's powers as commander-in-chief were purely military in character, those of any top general or top admiral.[44] Hamilton had said the same thing in Federalist No. 69.
Alongside the opinions of the Court of this period, however, stand certain opinions of Attorneys General that yield a less balanced bill of fare. For it is the case that, from the first down to the present year of grace, these family lawyers of the Administration in power have tended to favor expansive conceptions of presidential prerogative. As early as 1831 we find an Attorney-General arguing before the Supreme Court that, in performance of the trust enjoined upon him by the "faithful execution" clause, the President "not only may, but ... is bound to avail himself of every appropriate means not forbidden by law."[45] Especially noteworthy is a series of opinions handed down by Attorney-General Cushing in the course of the years 1853 to 1855. In one of these the Attorney-General laid down the doctrine that a marshal of the United States, when opposed in the execution of his duty by unlawful combinations too powerful to be dealt with by the ordinary processes of a federal court, had authority to summon the entire able-bodied force of his precinct as a posse comitatus, comprising not only bystanders and citizens generally but any and all armed forces,[46] which is precisely the theory upon which Lincoln based his call for volunteers in April, 1861.
Also manifest is the debt of Lincoln's message of July 4, 1861, to these opinions. Here in so many words the President lays claim to "the war power", partly on the ground of his duty to "take care that the laws be faithfully executed", partly in reliance on his powers as Commander-in-Chief, incidentally furnishing thereby a formula which has frequently reappeared in opinions of Attorneys-General in recent years. Nor did Lincoln ever relinquish the belief that on the one ground or the other he possessed extraordinary resources of power which Congress lacked and the exercise of which it could not control—an idea in the conscientious pursuit of which his successor came to the verge of utter disaster.
When first confronted with Lincoln's theory in the Prize Cases,[47] in the midst of war, a closely divided Court treated it with abundant indulgence; but in Ex parte Milligan[48] another closely divided Court swung violently to the other direction, adopting the comfortable position that the normal powers of the government were perfectly adequate to any emergency that could possibly arise, and citing the war just "happily terminated" in proof. But once again the principle of equilibrium asserted itself. Five months after Milligan, the same Bench held unanimously in Mississippi v. Johnson[49] that the President is not accountable to any court save that of impeachment either for the nonperformance of his constitutional duties or for the exceeding of his constitutional powers.
This was in the 1866-1867 term of Court. Sixteen years later, in 1882, Justice Samuel Miller gave classic expression to the principle of "a government of laws and not of men" in these words: "No man is so high that he is above the law.... All officers are creatures of the law and are bound to obey it."[50] Eight years later this same great Judge queried whether the President's duty to take care that the laws be faithfully executed is "limited to the enforcement of acts of Congress or of treaties according to their express terms," whether it did not also embrace "the rights, duties, and obligations growing out of the Constitution itself ... and all the protection implied by the nature of the government under the Constitution."[51] Then in 1895, in the Debs Case,[52] the Court sustained unanimously the right of the National Executive to go into the federal courts and secure an injunction against striking railway employees who were interfering with interstate commerce, although it was conceded that there was no statutory basis for such action. The opinion of the Court extends the logic of the holding to any widespread public interest.
The great accession to presidential power in recent decades has been accompanied by the breakdown dealt with earlier of the two great structural principles of the American Constitutional System, the doctrine of Dual Federalism and the doctrine of the Separation of Powers. The first exponent of "the New Presidency", as some termed it, was Theodore Roosevelt, who tells us in his Autobiography that the principle which governed him in his exercise of the presidential office was that he had not only a right but a duty "to do anything that the needs of the Nation demanded unless such action was forbidden by the Constitution or by the laws."[53] In his book, Our Chief Magistrate and his Powers, Ex-President Taft warmly protested against the notion that the President has any constitutional warrant to attempt the role of a "Universal Providence."[54] A decade earlier his destined successor, Woodrow Wilson, had avowed the opinion that "the President is at liberty, both in law and conscience, to be as big a man as he can".[55]
