Clause 10. The Congress shall have Power *** To define and punish Piracies and Felonies committed on the high Seas, and Offences against the Law of Nations.
PIRACIES, FELONIES, AND OFFENSES AGAINST THE LAW OF NATIONS
Origin of the Clause
When the United States ceased to be a part of the British empire, and assumed the character of an independent nation, they became subject to that system of rules which reason, morality, and custom had established among civilized nations of Europe, as their public law.... The faithful observance of this law is essential to national character....1473 These words of the Chancellor Kent expressed the view of the binding character of international law that was generally accepted at the time the Constitution was adopted. During the Revolutionary War, Congress took cognizance of all matters arising under the law of nations and professed obedience to that law.1474 Under the Articles of Confederation, it was given exclusive power to appoint courts for the trial of piracies and felonies committed on the high seas, but no provision was made for dealing with offenses against the law of nations.1475 The draft of the Constitution submitted to the Convention of 1787 by its Committee of Detail empowered Congress to declare the law and punishment of piracies and felonies committed on the high seas, and the punishment of counterfeiting the coin of the United States, and of offences against the law of nations.1476 In the debate on the
floor of the Convention, the discussion turned on the question as to whether the terms, felonies and the law of nations, were sufficiently precise to be generally understood. The view that these terms were often so vague and indefinite as to require definition eventually prevailed and Congress was authorized to define as well as punish piracies, felonies, and offenses against the law of nations.1477chanrobles-red

Definition of Offenses
The fact that the Constitutional Convention considered it necessary to give Congress authority to define offenses against the law of nations does not mean that in every case Congress must undertake to codify that law or mark its precise boundaries before prescribing punishments for infractions thereof. An act punishing the crime of piracy, as defined by the law of nations was held to be an appropriate exercise of the constitutional authority to define and punish the offense, since it adopted by reference the sufficiently precise definition of International Law.1478 Similarly, in Ex parte Quirin,1479 the Court found that by the reference in the Fifteenth Article of War to offenders or offenses that . . . by the law of war may be triable by such military commissions . . ., Congress had exercised its authority to define and punish offenses against the law of nations by sanctioning, within constitutional limitations, the jurisdiction of military commissions to try persons for offenses which, according to the rules and precepts of the law of nations, and more particularly the law of war, are cognizable by such tribunals.1480 Where, conversely, Congress defines with particularity a crime which is an offense against the law of nations, the law is valid, even if it contains no recital disclosing that it was enacted pursuant to this clause. Thus, the duty which the law of nations casts upon every government to prevent a wrong being done within its own dominion to another nation with which it is at peace, or to the people thereof, was found to furnish a sufficient justification for the punishment of the counterfeiting within the United States, of notes, bonds, and other securities of foreign governments.1481chanrobles-red

Extraterritorial Reach of the Power
Since this clause contains the only specific grant of power to be found in the Constitution for the punishment of offenses outside the territorial limits of the United States, a lower federal court held in 19321482 that the general grant of admiralty and maritime jurisdiction by Article III, § 2, could not be construed as extending either the legislative or judicial power of the United States to cover offenses committed on vessels outside the United States but not on the high seas. Reversing that decision, the Supreme Court held that this provision cannot be deemed to be a limitation on the powers, either legislative or judicial, conferred on the National Government by Article III, § 2. The two clauses are the result of separate steps independently taken in the Convention, by which the jurisdiction in admiralty, previously divided between the Confederation and the States, was transferred to the National Government. It would be a surprising result, and one plainly not anticipated by the framers or justified by principles which ought to govern the interpretation of a constitution devoted to the redistribution of governmental powers, if part of them were lost in the process of transfer. To construe the one clause as limiting rather than supplementing the other would be to ignore their history, and without effecting any discernible purpose of their enactment, to deny to both the States and the National Government powers which were common attributes of sovereignty before the adoption of the Constitution. The result would be to deny to both the power to define and punish crimes of less gravity than felonies committed on vessels of the United States while on the high seas, and crimes of every grade committed on them while in foreign territorial waters.1483 Within the meaning of this section, an offense is committed on the high seas even where the vessel on which it occurs is lying at anchor on the road in the territorial waters of another country.1484chanrobles-red
