The Allied Control Council is composed of the authorized representatives of the Four Powers: The United States, Great Britain, France, and the Soviet Union.
The preamble to Control Council Law No. 10 is in part as follows:
"In order to give effect to the terms of the Moscow Declaration of 30 October 1943 and the London Agreement of 8 August 1945, and the Charter issued pursuant thereto and in order to establish a uniform legal basis in Germany for the prosecution of war criminals and other similar offenders, * * * the Control Council enacts as follows:".
Article I reads in part as follows:
"The Moscow Declaration of 30 October 1943 'Concerning Responsibility of Hitlerites for Committed Atrocities' and the London Agreement of 8 August 1945 'Concerning Prosecution and Punishment of Major War Criminals of the European Axis' are made integral parts of this Law. ***" The London Agreement, supra, provides that the Charter of the International Military Tribunal (hereinafter called the IMT Charter), "shall form an integral part of this agreement". (London Agreement, Article II). Thus, it appears that the indictment is drawn under and pursuant to the provisions of Control Council Law No. 10 (hereinafter called C.C. Law 10), that C.C. Law 10 expressly incorporates the London Agreement as a part thereof, and that the IMT Charter is a part of the London Agreement.
Article 2 of C.C. Law 10 defines acts, each of which "is recognized as a crime", namely: (a) crimes against peace;
(b) war crimes; (c) crimes against humanity; (d) membership in criminal organizations. We are concerned here with categories b, c, d, only, each of which will receive later consideration.
The Procedural Ordinance
C.C. Law 10 provides that:
"Each occupying authority, within its zone of occupation, (a) shall have the right to cause persons within such zone suspected of having committed a crime, including those charged with crime by one of the United Nations, to be arrested * * *" (Article III, paragraph 1 (a)), and "shall have the right to cause all persons so arrested and charged * * * to be brought to trial before an appropriate tribunal." (Article III, paragraph 1 (d)). "The Tribunal by which persons charged with offenses hereunder shall be tried, and the rules and procedure thereof, shall be determined or designated by each zone commander for his respective zone * * *" (Article III, paragraph 2).Pursuant to the foregoing authority, Ordinance No. 7 was enacted by the Military Governor of the American Zone.
It provides:
"Article 1. Purpose. -- The purpose of this Ordinance is to provide for the establishment of military tribunals which shall have power to try and punish persons charged with offenses recognized as crimes in Article II of Control Council Law No. 10, including conspiracies to commit any such crimes.* * *" "Article II. Military Tribunal Constituted: (a) Pursuant to the powers of the Military Governor for the United States Zone of Occupation within Germany and further pursuant to the powers conferred upon the Zone Commander by Control Council Law No. 10 and Articles 10 and 11 of the Charter of the International Military Tribunal annexed to the London Agreement of 8 August 1945 certain tribunals to be known as Military Tribunals' shall be established hereunder."
The Tribunals authorized by Ordinance 7 are dependent upon the substantive jurisdictional provisions of C.C. Law 10 and are thus based upon international authority and retain international characteristics. It is provided that the United States Military Governor may agree with other zone commanders for a joint trial. (Ordinance 7, Article 2 (c). The Chief of Counsel for War Crimes, United States, may invite others of the United Nations to participate in the prosecution. (Ordinance 7, Article 3 (b)).
The Ordinance provides:
"The determinations of the International Military Tribunal in the judgments in Case No. 1 that invasions, aggressive acts, aggressive wars, crimes, atrocities, or inhumane acts were planned or occurred, shall be binding on the tribunals established hereunder and shall not be questioned except in so far as the participation therein or knowledge thereof by any particular person may be concerned. Statements of the International Military Tribunal in the judgment in Case No. 1 constitute proof of the facts stated, in the absence of substantial new evidence to the contrary."
(Ordinance No. 7, Article X).
The sentences authorized by Ordinance No. 7 are made definite only by reference to those provided for by C.C. Law 10. (Ordinance No. 7, Article 16).
As thus established the Tribunal is authorized and empowered to try and punish the major war criminals of the European Axis and "those German officers and men and members of the Nazi Party who have boon responsible for, or have taken a consenting part in"; or have aided, abetted, ordered; or have boon connected with plans or enterprises involving the commission of the offenses defined in C.C. law 10.
Source of Authority of C.C. Law 10 Having identified the instruments which purport to establish the jurisdiction of this Tribunal; we next consider the legal basis of those instruments.
The unconditional surrender of Germany took place on 8 May 1945. (Department of State publication No. 2423, page 24). The surrender was preceded by the complete disintegration of the central government and was followed by the complete occupation of all of Germany. There were no opposing German forces in the field; the officials who during the war had exercised the powers of the Reich Government were either dead, in prison, or in hiding. On 5 June 1945 the Allied Powers announced that they "hereby assume supreme authority with respect to Germany, including all the powers possessed by the German Government, the high command, and any State, municipal or local government or authority", and declared that "there is no central government or authority in Germany capable of accepting responsibility for the maintenance of order, the administration of the country, and compliance with the requirements of the victorious powers". The Four Powers further declared that they will hereafter determine the boundaries of Germany or any part thereof and the status of Germany or of any area at present being a part of German territory." (Berlin Declaration of 5 June 1945, Department of State publication No. 2423, pages 62, 63).On 2 August 1945 at Berlin, President Truman, Generalissimo Stalin, and Prime Minister Atlee, as heads of the Allied Powers, entered into a written agreement setting forth the principles which were to govern Germany during the initial control period.
Reference to that document will disclose the wide scope of authority and control which was assumed and exercised by the Allied Powers. They assumed "supreme authority" and declared that it was their purpose to accomplish complete demilitarization of Germany; to destroy the National Socialist Party; to prevent Nazi propaganda; to abolish all Nazi laws which "established discrimination on grounds of race, creed, or political opinion" * * * "whether legal, administrative, or otherwise"; to control education; to reorganize the judicial system in accordance with the principles of democracy and of equal rights; to accomplish the decentralization of the political structure. The agreement provided that "for the time being no central German government shall be established". In the economic field they assumed control of "German industry and all economic and financial international transactions". Finally, the Allies re-affirmed their intention to bring the Nazi war criminals to swift and sure justice. "Department of State publication No. 2423, page 10, et seq.).
It is this fact of the complete disintegration of the government in Germany, followed by unconditional surrender and by occupation of the territory, which explains and justifies the assumption and exercise of supreme governmental power by the Allies. The same fact distinguishes the present occupation of Germany from the type of occupation which occurs when, in the course of actual warfare, an invading army enters and occupies the territory of another State, whose government is still in existence and is in receipt of international recognition, and whose armies, with those of its Allies, are still in the field. In the latter case the occupying power is subject to the limitations imposed upon it by The Hague Convention and by the laws and customs of war.
In the former case (the occupation of Germany) the Allied Powers were not subject to those limitations. By reason of the complete breakdown of government, industry, agriculture and supply, they were under an imperative humanitarian duty of far wider scope to reorganize government and industry and to foster local democratic governmental agencies throughout the territory.
In support of the distinction made, we quote from two recent and scholarly articles in The American Journal of International Law.
"On the other hand, a distinction is clearly warranted between measures taken by the Allies prior to destruction of the German government and those taken thereafter. Only the former need be tested by the Hague Regulations, which are inapplicable to the situation now prevailing in Germany. Disappearance of the German State as a belligerent entity, necessarily implied in the Declaration of Berlin of 5 June 1945, signifies that a true state of war -- and hence belligerent occupation -- no longer exists within the meaning of international law."
--Freeman, in The American Journal of International Law, July 1947, page 605.
"Through the subjugation of Germany the outcome of the war has been decided in the most definite manner possible. One of the prerogatives of the Allies resulting from the subjugation is the right to occupy German territory at their discretion. This occupation is, both legally and factually, fundamentally different from the belligerent occupation contemplated in the Hague Regulations, as can be seen from the following observations.
"The provisions of the Hague Regulations restricting the rights of an occupant refer to a belligerent who, favored by the changing fortunes of war, actually exercises military authority over enemy territory and thereby prevents the legitimate who remains the legitimate sovereign -- from exercising his full authority.
The regulations draw important legal conclusions from the fact that the legitimate sovereign may at any moment himself be favored by the changing fortunes of war, reconquer the territory, and put an end to the occupation. 'The occupation applies only to territory where such authority (i.e., the military authority of the hostile State) is established and can be exercised' (Art. 42, 2). In other words, the Hague Regulations think of an occupation which is a phase of an as yet undecided war. Until 7 May 1945, the Allies were belligerent occupants in the then-occupied parts of Germany, and their rights and duties were circumscribed by the respective provisions of the Hague Regulations. As a result of the subjugation of Germany the legal character of the occupation of German territory was drastically changed."
--Fried, The American Journal of International Law, Vol.
40, No. 2, April 1946, page 327.
The view expressed by the two authorities cited appears to have the support of the International Military Tribunal judgment in the case against Goering, et al. In that case the defendants contended that Germany was not bound by the rules of land warfare in occupied territory because Germany had completely subjugated those countries and incorporated them into the German Reich. The Tribunal refers to the "doctrine of subjugation, dependent as it is upon military conquest", and holds that it is unnecessary to decide whether the doctrine has any application where the subjugation is the result of the crime of aggressive war. The reason given is significant. The Tribunal said:
"The doctrine was never considered to be applicable so long as there was an army in the field attempting to restore the occupied territories to their true owners, and in this case, therefore, the doctrine could not apply to any territories occupied after 1 September 1939."
(Volume 1, Official Text, IMT Trials, page 254).
The clear implication from the foregoing is that the rules of land warfare apply to the conduct of a belligerent in occupied territory so long as there is an army in the field attempting to restore the country to its true owner, but that those rules do not apply when belligerency is ended, there is no longer an army in the filed, and, as in the case of Germany, subjugation has occurred by virtue of military conquest.
The views which we have expressed are supported by modern scholars of high standing in the field of international law. While they differ somewhat in theory as to the present legal status of Germany and concerning the situs of residual sovereignty, they appear to be in accord in recognizing that the powers and rights of the allied governments under existing conditions in Germany are not limited by the provisions of the Hague Regulations concerning land warfare. For reference see:

Article published in Neue Justiz (New Justice) by Dr. Alfons Steininger, Berlin, Volume I, No. 7, July 1947, pages 146-150.
In an article by George A. Zinn, Minister of Justice of Hessen, entitled "Germany as the Problem of the Law of States", the author points out that if it be assumed that the present occupation of Germany constitutes "belligerent occupation" in the traditional sense, then all statutory and constitutional changes brought about since 7 May 1945 would cease to be valid once the Allied troops were withdrawn and all Nazi laws would main and automatically become the law of Germany, a consumation devoutly to be avoided.
Both of the authorities first cited directly assert that the situation at the time of the unconditional surrender resulted in the transfer of sovereignty to the Allies. In this they are supported by the weighty opinion of Lord Wright, eminent jurist of the British House of Lords and head of the United Nations War Crimes Commission. For our purposes, however, it is unnecessary to determine the present situs of "residual sovereignty". It is sufficient to hold that, by virtue of the situation at the time of unconditional surrender, the Allied Powers were provisionally in the exercise of supreme authority, valid and effective until such time as, by treaty or otherwise, Germany shall be permitted.to exercise the full powers of sovereignty. We held that the legal right of the Four Powers to enact C.C. Law 10 is established and that the jurisdiction of this Tribunal to try persons charged as major war criminals by the European Axis must be conceded.
We have considered it proper to set forth our views concerning the nature and source of the authority of C.C. Law 10 in its aspect as substantive legislation. It would have been possible to treat that law as a binding rule regardless of the righteousness of its provisions, but its justification must ultimately depend upon accepted principles of justice and morality, and we are not content to treat the statute as a mere rule of thumb to be blindly applied.
We shall shortly demonstrate that the Charter and C.C. Law 10 provide for the punishment of crimes against humanity. As set forth in the indictment the acts charged as crimes against humanity were committed before the occupation of Germany. They were described as racial persecutions by Nazi officials perpetrated upon German nationals. The crime of genocide is an illustration. We think that a tribunal charged with the duty of enforcing these rules will do well to consider, in determining the degree of punishment to be imposed, the moral principles which underlie the exercise of power. For that reason we have contrasted the situation when Germany was in belligerent occupation of portions of Poland, with the situation existing under the Four Power occupation of Germany since the surrender. The occupation of Poland by Germany was in every sense belligerent occupation, precarious in character, while opposing armies were still in the field. The German occupation of Poland was subject to the limitations imposed by The Hague Convention and the laws and customs of land warfare. In view of these limitations we doubt if any person would contend that Germany, during that belligerent occupation, could lawfully have provided tribunals for the punishment of Polish officials who, before the occupation by Germany, had persecuted their own people, to wit: Polish nationals. How the Four Powers are providing by C.C. Law 10 for the punishment of German officials who, before the occupation of Germany, passed and enforced laws for the persecution of German nationals upon racial grounds. It appears that it would be equally difficult to justify such action of the Four Powers if the situation here is the same as the situation which existed in Poland under German occupation and if consequently the limitations of The Hague Convention were applicable. For this reason it seems appropriate to point out the distinction between the two situations. As we have attempted to show, the moral and legal justification under principles of international law which authorizes the broader scope of authority under C.C. Law 10 is based on the fact that the Four Powers are not now in belligerent occupation or subject to the limitations set forth in the rules of land warfare.
Rather, they have justly and legally assumed the broader task in Germany which they have solemnly defined and declared, to wit: the task of reorganizing the German government and economy and of punishing persons who, prior to the occupation, were guilty of crimes against humanity committed, against their own nationals. We have pointed out that this difference in the nature of the occupations is due to the unconditional surrender of Germany and the ensuing chaos which required the Four Powers to assume provisional supreme authority throughout the German Reich. We are not attempting to pass judicially upon a question which is solely within the jurisdiction of the political departments of the Four Powers. The fixing of the date of the formal end of the war and similar matters will, of course, be dependent upon the action of the political departments. We do not usurp their function. We merely inquire, in the course of litigation when the lives of men are dependent upon decisions which must be both legal and just, whether the great objectives announced by the Four Powers are themselves in harmony with the principles of international law and morality.
In declaring that the expressed determination of the victors to punish German officials who slaughtered their own nationals is in harmony with international principles of justice, we usurp no power; we only take judicial notice of the declarations already made by the chief executives of the United States and her former Allies. The fact that C.C. Law 10 on its face is limited to the punishment of German criminals does not transform this Tribunal into a German court. The fact that the Four Powers are exercising supreme legislative authority in governing Germany and for the punishment of German criminals does not mean that the jurisdiction of this Tribunal rests in the slightest degree upon any German law, prerogative, or sovereignty. We sit as a Tribunal drawing its sole power and jurisdiction from the will and command of the four occupying powers.
Examination will disclose that C.C. Law 10 possesses a dual aspect. In its first aspect and on its face it purports to be a statute defining crimes and providing for the punishment of persons who violate its provisions. It is the legislative product of the only body in existence having and exercising general lawmaking power throughout the Reich. The first International Military Tribunal in the case against Goering, et al., recognized similar provisions of the IMT Charter as binding legislative enactments. We quote;
"The making of the Charter was the exercise of the sovereign legislative power by the countries to which the German Reich unconditionally surrendered; and. the undoubted right of these countries to legislate for the occupied territories has been recognized by the civilized world. * * * These provisions are binding upon the Tribunal as the law to be applied to the case." (Trial of the major war criminals (Official Text - Nurnberg, 1947), Volume 1, pages 218 and 174).
Since the Charter and C.C. Law 10 are the product of legislative action by an international authority, it follows of necessity that there is no national constitution of any one State which could be invoked to invalidate the substantive provisions of such international legislation. It can scarcely be armed that a court which owes its existence and jurisdiction solely to the provisions of a given statute could assume to exercise that jurisdiction and then, in the exercise thereof, declare invalid the act to which it owes its existence. Except as an aid to construction, we cannot and need not go behind the statute. This was discussed authoritatively by the first International Military Tribunal in connection with the contention of defendants that the Charter was invalid because it partook of the nature of ex-post facto legislation. That Tribunal said, "The Charter makes the planning or waging of a war of aggression or a war in violation of international treaties a crime; and it is, therefore, not strictly necessary to consider whether and to what extent aggressive war was a crime before the execution of the London Agreement."
(Trial of major war criminals, Volume 1, page 219).
As recently said by an American authority?
"The Charter was, of course, binding upon the Tribunal in the same way that a constitutional statute would bind a domestic court." (Issues of the Nurnberg Trials, by Herbert Wechsler, Political Science Quarterly, March 1947, page 14).
In its aspect as a statute defining crime and providing punishment the limited purpose of C.C. Law 10 is clearly set forth. It is an exercise of supreme legislative power in and for Germany. It does not purport to establish by legislative act any new crimes of international applicability. The London Agreement refers to the trial of "those German officers and men and members of the Nazi Party who have been responsible for * * * atrocities." C.C. Law 10 recites that it was enacted to establish a "uniform legal basis in Germany" for the prosecution of war criminals.
Military Government Ordinance No. 7 was enacted pursuant to the powers of the Military Government for the United States Zone of Occupation "within Germany".
We concur in the view expressed by the first International Military Tribunal as quoted above, but we observe that the decision was supported on two grounds. The Tribunal in that case did not stop with the declaration that it was bound by the Charter as an exercise of sovereign legislative power. The opinion went on to show that the Charter was also "an expression of international law at the time of its creation". All of the war crimes and many, if not all, of the crimes against humanity as charged in the indictment in the case at bar were, as we shall show, violative of pre-existing principles of international law. To the extent to which this is true, C.C. Law 10 may be deemed to be a codification rather than original substantive legislation.
Insofar as C.C. Law 10 may be thought to be beyond, established principles of international law, its authority, of course, rests upon the exercise of the "sovereign legislative power" of the countries to which the German Reich unconditionally surrendered.
We have discussed C.C. Law 10 in its first aspect as substantive legislation. We now consider its other aspect. Entirely aside from its character as substantive legislation, C.C. Law 10, together with Ordinance No. 7, provides procedural means previously lacking for the enforcement within Germany of certain rules of international law which exist throughout the civilized world independently of any new substantive legislation. (Ex Parte Quirin, 317 U.S. 1; 87 L. ed. 3; 63 S. Ct. 2). International law is not the product of statute. Its content is not static. The absence from the world of any governmental body authorized to enact substantive rules of international law has nor prevented the progressive development of that law. After the manner of the English common law it has grown to meet the exigencies of changing conditions.
It must be conceded that the circumstance which gives to principles of international conduct the dignity and authority of law is their general acceptance as such by civilized nations, which acceptance is manifested by international treaties, conventions, authoritative textbooks, practice and judicial decisions. (Hackworth, Digest of International Law, Volume 1, Pages 1-4).
It does not, however, follow from the foregoing statements that general acceptance of a rule of international conduct must be manifested by express adoption thereof by all civilized States.
"The basis of the law, that is to say, what has given to some principles of general applicability the quality or character of law has been the acquiescence of the several independent States which were to be governed thereby." (Hyde, International Law, (2d rev. ed.), Vol. 1, page 4).
"The requisite acquiescence on the part of individual States has not been reflected in formal or specific approval of every restriction which the acknowledged requirements of international justice have appeared, under the circumstances of the particular case, to dictate or imply. It has been rather a yielding to principle, and by implication, to logical applications thereof which have begotten deep-rooted and approved practices."
(Hyde, supra, page 5). "It should be observed, however, that acquiescence in a proposal maybe inferred from the failure of interested States to make appropriate objection to practical applications of it. Thus it is that changes in the law may be wrought gradually and imperceptibly, like those which by process of accretion alter the course of a river and change an old boundary. Without conventional arrangement, and by practices manifesting a common and sharp deviation from rules once accepted as the law, the community of States may in fact modify that which governs its members."
(Hyde, supra, page 9).
"States may through the medium of an international organization such as the League of Nations, itself the product of agreement, find it expedient to create and accept fresh restraints that ultimately win widest approval and acceptance as a part of the law of nations. The acts of the organization may thus in fact become sources of international law, at least in case the members thereof have by their general agreement clothed it with power to create and put into force fresh rules of restraint." (Hyde, supra, page 11).
"But international law is progressive. The period of growth generally coincides with the period of world upheavals. The pressure of necessity stimulates the impact of natural law and of moral ideas and converts them into rules deliberately and overtly recognized by the consensus of civilized mankind. The experience of two great world wars within a quarter of a century cannot fail to have deep repercussions on the senses of the peoples and their demand for an international law which reflects international justice. I am convinced that international law has progressed, as it is bound to progress if it is to be a living and operative force in these days of widening sense of humanity."
(Lord Wright, "War Crimes under International Law", The Law Quarterly Review, Vol. 62, January 1946, page 51).
For the reasons stated by Lord Wright, this growth by accretion has been greatly accelerated since the First World War. (Hyde, International Law, (2d rev. ed.), Volume 1, page 8). The Charter, the I.M.T. Judgment, and C.C. Law 10 are merely "great new cases in the book of international law). They constitute authoritative recognition of principles of individual penal responsibility in international affairs which, as we shall show, had been developing for many years. Surely C.C. Law 10, which was enacted by the authorized representatives of the four greatest powers on earth, is entitled to judicial respect when it states, "Each of the following acts is recognized as a crime". Surely the requisite international approval and acquiescence is established when twenty-three States, including all of the great powers, have approved the London Agreement and the I.M.T. Charter without dissent from any State. Surely the Charter must be deemed declaratory of the principles of international law in view of its recognition as such by the General Assembly of the United Nations. We quote:
"The General Assembly recognizes the obligation laid upon it by Article 13, paragraph 1, subparagraph (a) of the Charter, to initiate studies and make recommendations for the purpose of encouraging the progressive development of international law and its codification;
"Takes note of the agreement for the establishment of an International Military Tribunal for the prosecution and punishment of the major war criminals of the European Axis, signed in London on 8 August 1945, and of the Charter annexed thereto, and of the fact that similar principles have been adopted in the Charter of the International Military Tribunal for the trial of the major war criminals in the Far East, proclaimed at Tokyo on 19 January 1946;
"Therefore, "Affirms the principles of international law recognized by the Charter of the Nuernberg Tribunal and the judgment of the Tribunal:
"Directs the Committed on codification of international law established by the resolution of the General Assembly of ..... December 1946, to treat as a matter of primary importance plans for the formulation, in the text of a general codification of offenses against the peace and security of mankind, of of an International Criminal Code, of the principles recognized in the Charter of the Nuernberg Tribunal and in the judgment of the Tribunal."
(Journal of the United Nations, No. 58, Supp. A - A/P. V./55, p. 485; ("The Crime of Aggression and the Future of International Law", by Philip C. Jessup, Political Science Quarterly, Vol. LXII. March 1947, Number 1, page 2).)
Before the International Military Tribunal had convened for the trial of Goering, et al., the opinion had been expressed that through the process of accretion the provisions of the I.M.T, Charter and consequently of C.C. Law 10 had already, in large measure, become incorporated into the body of international law. We quote:
"I understand the Agreement to import that the three classes of persons which it specifies are war criminals, that the acts mentioned in classes (a), (b) and (c) are crimes for which there is properly individual responsibility; that they are not crimes because of the Agreement of the four Governments, but that the Governments have scheduled them as coming under the jurisdiction of the Tribunal because they are already crimes by existing law. On any other assumption the Court would not be a Court of law but a manifestation of power. The principles which are declared in the Agreement are not laid down as an arbitrary direction to the Court but are intended to define and do, in my opinion, accurately define what is the existing international law on these matters," (Lord Wright, "War Crimes under International Law", The Law Quarterly Review, Vol.
62, January 1946, page 41).
A similar view was expressed in the Judgment of the International Military Tribunal. We quote:
"The Charter is not an arbitrary exercise of power on the part of the victorious nations, but in the view of the Tribunal, as will be shown, it is the expression of international law existing at the time of its creation; and to that extent is itself a contribution to international law." (I.M.T. Judgment, page 218). We are empowered to determine the guilt or innocence of persons accused of acts described as "war crimes" and "crimes against humanity" under rules of international law.
At this point, in connection with cherished doctrines of national sovereignty, it is important to distinguish between the rules of common international law which are of universal and superior authority on the one hand, and the provisions for enforcement of those rules which are by no means universal on the other. As to the superior authority of international law, we quote:
"If there exists a body of international law which States, from a sense of legal obligation do in fact observe in their relations with each other, and which they are unable individually to alter or destroy, that law must necessarily be regarded as the law of each political entity deemed to be a State, and as prevailing throughout places under its control. This is true although there be no local affirmative action indicating the adoption by the individual State of international law. * * * International law, as the local law of each State, is necessarily superior to any administrative regulation or statute or public act at variance with it. There can be no conflict on an equal plane." (Hyde, International Law, ((2d rev. ed.),) Vol. 1, pages 16, 17).
This universality and superiority of international law does not necessarily imply universality of its enforcement. As to the puhishment of persons guilty of violating the laws and customs of war (war crimes in the narrow sense), it has always been recognized that tribunals may be established and punishment imposed by the State into whose hands the perpetrators fall. Those rules of international law were recognized as paramount, and jurisdiction to enforce them by the injured belligerent government, whether within the territorial boundaries of the State or in occupied territory, has been unquestioned.
