Now, that Act of 1790 is, we say, constitutional. And here I may as well say what seems to be necessary in reference to the point made by Mr. Brady on behalf of the prisoners. He will contend, he says, that the ninth section of the Act of 1790 is beyond the constitutional power of Congress—its constitutional power in the premises being limited, as he supposes, to the right to define and punish the crime of piracy.

Mr. Brady: "And offences against the law of nations."

Mr. Evarts: To that explicit clause in the Constitution.

Now, your honors will notice what the crime in the ninth section of the Act of 1790 is. It is not piracy so described, nor robbery so described merely, but it is a statutory definition of the crime, which includes a particular description and predicament of the offender (the eighth section having included all persons), and also defines the subject of the robbery, or the object of the piratical aggression. It is this: "If any citizen shall commit any piracy or robbery aforesaid, or any act of hostility against the United States, or any citizen thereof," &c. "Piracy or robbery aforesaid" would, of course, include the definition of the crime as embraced in the eighth section. But, the ninth section proceeds to add a new and substantive completeness of crime, not described either as piracy or robbery, to wit: "Or any act of hostility against the United States, or any citizen thereof, upon the high seas, under color of any commission from any foreign Prince or State, or on pretence of authority from any person, such offender shall, notwithstanding the pretence of any such authority, be deemed, adjudged, and taken to be a pirate, felon, and robber, and, on being thereof convicted, shall suffer death."

Now, it is quite immaterial whether this statute is accurate in declaring the offender to be "a pirate, felon, and robber." It has made the offence a crime. Under what restrictions has it made it a crime? Has it undertaken to extend the jurisdiction of the Federal Government, as supported by the law of nations respecting piracy, which is a right on the part of every nation to legislate not only for its own citizens—not only in protection of its own property—but in punishment of all pirates, of whatever origin, and in protection of all property on sea, and wherever owned? Now that, undoubtedly, is the jurisdiction under the law of nations, and neither by the Constitution has Congress received any greater power under the law of nations than that, nor, I respectfully submit, can it receive any greater power under the law of nations; that is, Congress cannot receive any power greater than that which other nations, not bound by our municipal statutes, would be bound to respect, as sustained by the law of nations. Now I agree that "any act of hostility against the United States, or any citizen thereof," would not necessarily be up to the grade and of the quality of piracy under the law of nations; and that the Congress of the United States, in undertaking to make laws which would create an offence, and punish it as piracy, which was not piracy by the law of nations, and in seeking to enforce its jurisdiction and inflict its sanctions on a people who owed it no municipal obedience, and in protection of property over which it had no municipal control, and no duty to perform, could not control foreign nations; and that foreign nations would not be bound to respect convictions obtained under such a municipal extension of our law over persons never subject to us, and in respect to property never under our dominion.

And thus your honors see that, just in proportion as the ninth section has extended the crime, it has limited both the persons to whom the statute is applied, and the property in respect of which the crime is defined. It is wholly limited to our own citizens, subject to whatever laws we choose to make for our own government, and in respect of the marine property of the United States, and of its citizens when at sea, which, by every rule of the extension or limit of municipal authority, is always regarded, on general principles of public jurisprudence, as a part of the property and of the territory of the nation to which the ship and cargo belong, wherever it may be on the high seas.

Now, this ninth section, I suppose, if your honors please,—and such I understand to be the views of Judge Sprague, as expressed by him to the Grand Jury, at Boston,—proceeds and is supported on the general control given by the Constitution to Congress over all external commerce, which, I need not say, must, to be effective, extend to the criminal jurisprudence which protects against wrong, and the criminal control which punishes crime perpetrated by our citizens on our own commerce on the high seas. My learned friend would certainly not contend that the different States had this authority in reference to crimes on the high seas. And, if they have not that authority, then, between these jurisdictions, we should have omitted one of the most necessary, one of the most ordinary, one of the wisest and plainest duties of Governments in regard to the protection of their commerce. For, it is idle to say that there are no crimes which may be committed at sea which are not piracy, and that there is no protection needed for our own commerce against our own citizens which does not fall within the international law of piracy.

Mr. Brady: I ask Mr. Evarts' permission to make a suggestion upon this point, which it is due to him, and to myself, also, that I should present, that I may hear his views in respect to it. I would ask the learned gentleman, and the Court, to suppose the case of an American citizen who, on the breaking out of a war between the United States and England, should be residing in England as a denizen, and who had resided there for many years, and who should take a commission for privateering from the British Government, regularly issued, having about it all the sanctions belonging to such an authority, and who, in the prosecution of a war, should take an American prize,—would he be liable to be convicted in the Courts of the United States of piracy or robbery, under the act of 1790? He clearly would, on its language. And then the question occurs—Had Congress any authority to pass such a law?

Now, I will put a case which is stronger, and which comes equally within the plain terms, purview, and spirit of that Act, upon a literal construction. Suppose that two American vessels should come into collision on the Pacific Ocean, each manned and officered exclusively by American citizens, and, an angry feeling being engendered, the Captain of one of them should direct a sailor to throw a belaying-pin at the Captain of the other, and the sailor should do it. That would clearly be an act of hostility against one citizen of the United States perpetrated by another, and would be perpetrated under pretence of authority from a person, to wit, the Captain of the ship who gave the violent order. Would the sailor be liable to a conviction for that offence, as a pirate or robber? and would Congress have the authority to pass such a law? I doubt it very much.

Mr. Evarts: I agree with my learned friend that the case which he first stated is not only within the words, but within the intent, of the ninth section.
