Here the power of arrest is given by the act of Parliament to the governor or his secretary; the process of the civil courts was wholly suspended; bail was denied and the parties imprisoned, and this not by process of the courts, but by warrant of a chief governor or his secretary; not for crimes charged to have been committed, but for being suspected of treasonable practices. Magna Charta, it seems, opposes no restraint, notwithstanding the parade that is made about it in this argument, upon the power of the Parliament of England to legalize arrests and imprisonments made before the passage of the act upon an executive order, and without colorable authority of statute law, and to authorize like arrests and imprisonments of so many of six million of people as such executive officers might suspect of treasonable practices.

But, says the gentleman, whatever may be the precedents, English or American, whatever may be the provisions of the Constitution, whatever may be the legislation of Congress, whatever may be the proclamations and orders of the President as Commander-in-Chief, it is a usurpation and a tyranny in time of rebellion and civil war to subject any citizen to trial for any crime before military tribunals, save such citizens as are in the land or naval forces, and against this usurpation, which he asks this court to rebuke by solemn decision, he appeals to public opinion. I trust that I set as high value upon enlightened public opinion as any man. I recognize it as the reserved power of the people which creates and dissolves armies, which creates and dissolves legislative assemblies, which enacts and repeals fundamental laws, the better to provide for personal security by the due administration of justice. To that public opinion upon this very question of the usurpation of authority, of unlawful arrests, and unlawful imprisonments, and unlawful trials, condemnations, and executions by the late President of the United States, an appeal has already been taken. On this very issue the President was tried before the tribunal of the people, that great nation of freemen who cover this continent, looking out upon Europe from their eastern and upon Asia from their western homes. That people came to the consideration of this issue not unmindful of the fact that the first struggle for the establishment of our nationality could not have been, and was not, successfully prosecuted without the proclamation and enforcement of martial law, declaring, as we have seen, that any inhabitant who, during that war, should kill any loyal citizen, or enter into any combination for that purpose, should, upon trial and conviction before a military tribunal, be sentenced as an assassin, traitor, or spy, and should suffer death, and that in this last struggle for the maintenance of American nationality the President but followed the example of the illustrious Father of his Country. Upon that issue the people passed judgment on the 8th day of last November, and declared that the charge of usurpation was false.

From this decision of the people there lies no appeal on this earth. Who can rightfully challenge the authority of the American people to decide such questions for themselves? The voice of the people, thus solemnly proclaimed, by the omnipotence of the ballot in favor of the righteous order of their murdered President, issued by him for the common defense, for the preservation of the Constitution, and for the enforcement of the laws of the Union, ought to be accepted, and will be accepted, I trust, by all just men, as the voice of God.

May it please the Court: I have said thus much touching the right of the people, under their Constitution, in time of civil war and rebellion, to proclaim through their Executive, with the sanction and approval of their Congress, martial law, and enforce the same according to the usage of nations.

I submit that it has been shown that, by the letter and spirit of the Constitution, as well as by its contemporaneous construction, followed and approved by every department of the government, this right is in the people; that it is inseparable from the condition of war, whether civil or foreign, and absolutely essential to its vigorous and successful prosecution; that according to the highest authority upon constitutional law, the proclamation and enforcement of martial law are "usual under all governments in time of rebellion"; that our own highest judicial tribunal has declared this, and solemnly ruled that the question of the necessity for its exercise rests exclusively with Congress and the President; and that the decision of the political departments of the government, that there is an armed rebellion and a necessity for the employment of military force and martial law in its suppression concludes the judiciary.

In submitting what I have said in support of the jurisdiction of this honorable court, and of its constitutional power to hear and determine this issue, I have uttered my own convictions; and for their utterance in defense of my country, and its right to employ all the means necessary for the common defense against armed rebellion and secret treasonable conspiracy in aid of such rebellion, I shall neither ask pardon nor offer apology. I find no words with which more fitly to conclude all I have to say upon the question of the jurisdiction and constitutional authority of this court than those employed by the illustrious Lord Brougham to the House of Peers in the support of the bill before referred to, which empowered the lord lieutenant of Ireland, and his deputies, to apprehend and detain, for the period of seven months or more, all such persons within that island as they should suspect of conspiracy against her Majesty's person and government. Said that illustrious man: "A friend of liberty I have lived, and such will I die; nor care I how soon the latter event may happen, if I cannot be a friend of liberty without being a friend of traitors at the same time—a protector of criminals of the deepest dye—an accomplice of foul rebellion and of its concomitant, civil war, with all its atrocities and all its fearful consequences."—Hansard's Debates, 3d series, vol. 100, p. 635.

May it please the Court: It only remains for me to sum up the evidence and present my views of the law arising upon the facts in the case on trial. The questions of fact involved in the issue are:—

First, did the accused, or any two of them, confederate and conspire together as charged? and—

Second, did the accused, or any of them, in pursuance of such conspiracy, and with the intent alleged, commit either or all of the several acts specified?

If the conspiracy be established, as laid, it results that whatever was said or done by either of the parties thereto, in the furtherance or execution of the common design, is the declaration or act of all the other parties to the conspiracy; and this, whether the other parties, at the time such words were uttered or such acts done by their confederates, were present or absent—here, within the intrenched lines of your capital, or crouching behind the intrenched lines of Richmond, or awaiting the results of their murderous plot against their country, its Constitution and laws, across the border, under the shelter of the British flag.
