Clearly defines the limits of executive powers.

Exerpt:

"The article begins by declaring that the executive power shall be vested in a president of the United States of America, to hold his office during the term of four years; and then proceeds to prescribe the mode of election, and to specify, in precise and plain words, the powers delegated to him, and the duties imposed upon him. The short term for which he is elected, and the narrow limits to which his power is confined, show the jealousy and apprehension of future danger which the framers of the constitution felt in relation to that department of the government, and how carefully they withheld from it many of the powers belonging to the executive branch of the English government which were considered as dangerous to the liberty of the subject; and conferred (and that in clear and specific terms) those powers only which were deemed essential to secure the successful operation of the government.

He is elected, as I have already said, for the brief term of four years, and is made personally responsible, by impeachment, for malfeasance in office; he is, from necessity, and the nature of his duties, the commanderinchief of the army and navy, and of the militia, when called into actual service; but no appropriation for the support of the army can be made by congress for a longer term than two years, so that it is in the power of the succeeding house of representatives to withhold the appropriation for its support, and thus disband it, if, in their judgment, the president used, or designed to use it for improper purposes. And although the militia, when in actual service, is under his command, yet the appointment of the officers is reserved to the states, as a security against the use of the military power for purposes dangerous to the liberties of the people, or the rights of the states.

So too, his powers in relation to the civil duties and authority necessarily conferred on him are carefully restricted, as well as those belonging to his military character. He cannot appoint the ordinary officers of government, nor make a treaty with a foreign nation or Indian tribe, without the advice and consent of the senate, and cannot appoint even inferior officers, unless he is authorized by an act of congress to do so. He is not empowered to arrest any one charged with an offence agaisnt the United States, and whom he may, from the evidence before him, believe to be guilty; nor can he authorize any officer, civil or military, to exercise this power, for the fifth article of the amendments to the constitution expressly provides that no person 'shall be deprived of life, liberty or property, without due process of law'that is, judicial process.

Even if the privilege of the writ of habeas corpus were suspended by act of congress, and a party not subject to the rules and articles of war were afterwards arrested and imprisoned by regular judicial process, he could not be detained in prison, or brought to trial before a military tribunal, for the article in the amendments to the constitution immediately following the one above referred to (that is, the sixth article) provides, that 'in all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial by an impartial jury of the state and district wherein the crime shall have been committed, which district shall have been previously ascertained by law; and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor; and to have the assistance of counsel for his defence.'

The only power, therefore, which the president possesses, where the 'life, liberty or property' of a private citizen is concerned, is the power and duty prescribed in the third section of the second article, which requires 'that he shall take care that the laws shall be faithfully executed.' He is not authorized to execute them himself, or through agents or officers, civil or military, appointed by himself, but he is to take care that they be faithfully carried into execution, as they are expounded and adjudged by the coordinate branch of the government to which that duty is assigned by the constitution. It is thus made his duty to come in aid of the judicial authority, if it shall be resisted by a force too strong to be overcome without the assistance of the executive arm; but in exercising this power he acts in subordination to judicial authority, assisting it to execute its process and enforce its judgments. $With such provisions in the constitution, expressed in language too clear to be misunderstood by any one, I can see no ground whatever for supposing that the president, in any emergency, or in any state of things, can authorize the suspension of the privileges of the writ of habeas corpus, or the arrest of a citizen, except in aid of the judicial power. He certainly does not faithfully execute the laws, if he takes upon himself legislative power, by suspending the writ of habeas corpus, and the judicial power also, by arresting and imprisoning a person without due process of law.

Nor can any argument be drawn from the nature of sovereignty, or the necessity of government, for selfdefence in times of tumult and dnager. The government of the United States is one of delegated and limited powers; it derives it existence and authority altogether from the constitution, and neither of its branches, executive, legislative or judicial, can exercise any of the powers of government beyond those specified and granted; for the tenth article of the amendments to the constitution, in express terms, provides that 'the powers not delegated to the United States by the constitution, nor prohibited by it to the states, are reserved to the states, respectively, or to the people.'
