tion, or exemption claimed under the commission or order or sanction of any foreign state, or under color thereof, the validity and effect whereof depends upon the law of nations.''57

Where consulates are declared inviolable by treaty and public vessels are in port, the government is under an obligation to prevent violation of such places. The usual method of keeping order by the police and, if necessary, by the employment of armed force, serve to fulfill this duty.58

(3) It has been officially held in the United States that resident aliens owe temporary allegiance to the government, must submit to its laws, 59 are entitled to the judicial remedies for wrongs open to citizens," but that the United States government is not responsible for injuries to them by acts of private trespassers." The alien must get his remedy by the usual legal processes or not at all. This view, it will be seen, puts aliens on the same legal footing as citizens. They have no immunities or advantages. In fact their rights are less secure than those of citizens, for they do not enjoy political privileges, and by the alien act62 in force from 1798 to 1801 they were liable to expulsion by

The British government and the political department of the U. S. government took the view that his act, done as a soldier and recognized by the British government, was one for diplomatic reparation, and personal liability could not attach.

order of the president. This view denies the doctrine of international responsibility for the safety of resident aliens, yet is the one generally expressed by the United States government. When reparation has been made by the government it has been as a 'gratuity." It has been denied that the government was under an obligation of international law to prevent injuries to aliens or to make reparation.63

This opinion to the contrary, it seems clear that responsibility is recognized in practice as a rule of international law. The principle is recognized by a number of state governments in laws making counties responsible for property losses and damages caused by mob violence. 65 Even though the United States denies the theory in principle, it has generally observed it in practice. We may therefore consider the measures taken to prevent injury to aliens.

By statute it is provided that persons violating safe conducts or passports of aliens shall be criminally liable in the federal courts. In numerous treaties rights of resident aliens are specified, extending to such matters as protection of life and property, right to own land, to make devises and bequests, and to have recourse to local courts of justice. In some of them it is specified that subjects of the contracting powers shall have the same rights. as citizens when in the United States, and most favored nation rights are frequently guaranteed to subjects of the respective powers: Treaty rights of this character are protected by the courts applying treaties as law.67

The courts have held that aliens within the territory are entitled to the same protection in their personal rights as citizens and no more, and this has been the principle generally acted upon in preventing injuries even when treaties do not specify such a privilege. The constitutional guarantees operate to pro

tect aliens resident in the country, though they are not effective to prevent arbitrary administrative methods in excluding aliens before arrival or expelling those illegally entering.70

The ordinary exercise of the police power, prevention of injury to persons, and punishment of offenders is in the hands of the state governments. It is therefore upon them that the duty of preventing injury to aliens largely devolves. The principle that treaties are enforcable law enunciated by the constitution is binding upon state as well as federal courts, and states have enforced the treaty rights of aliens in cases coming before them subject to the right of appeal to the United States supreme court should such rights be neglected. A similar control may be exercised in respect to the general protection of property and personal rights by such constitutional guarantees as those prohibiting state laws "impairing the obligation of contracts", or taking life, liberty or property without "due process of law." Thus the national government can in a measure prevent the confiscation of contract debts of foreigners, a matter which has been of international importance especially in Latin American countries, although it is not clear that international law imposes such a duty." But in the punishment and control of private individuals violating rights of aliens, either guaranteed by treaty or by international law, no such method of federal control over the state government exists. The international responsibility falls upon the national government. It has therefore sometimes happened that the national government has made reparation for failure on the part of the states to perform this duty of prevention even though it had by law no means of controlling the states or offering adequate protection itself.

During the decade from 1890 to 1900 a number of cases arose in which Italians were murdered or injured by mobs and in which the state authorities appear to have been lax in performing their duties of prevention. Presidents Harrison and McKinley strongly urged congress to enact laws giving the federal courts jurisdiction of cases involving injury to aliens, especially where treaty rights were involved, as was the case in the

Italian outrages.72 It seems that there is adequate constitutional basis for such legislation, both in the implied power of the national government to enforce treaties which it may constitutionally conclude, and in the power to define and punish offenses against the law of nations. W. W. Willoughby has said in this connection, "There would seem to be no valid constitutional objection to an act of congress giving to the federal courts cognizance of all offenses for which the United States may according to the law of nations be held responsible to foreign powers.''73

INFRACTION OF TREATIES

(1) Treaties may be declaratory of international law, in which case the contracting states have no more rights and no more duties than they would have under international law. They may be amendatory of international law, such as general international conventions, in which case, after ratification, their provisions are international law and the contracting states are under new duties according to them. Or they may create exceptions to the general rule of international law, being in nature similar to contracts. In some such treaties the national obligations are made greater than under international law, as in treaties guaranteeing special protection to aliens or special protection to territory such as Panama and Cuba. In other cases the national duties are made less than they would be under international law. The protocols with Mexico relating to Indian marauders and the capitulations of Turkey and other non-Christian countries reduce the usual obligations of abstaining from exercising force and jurisdiction in foreign territory, although they add new obligations incidental to the exercise of these privileges.

Treaty stipulations are considered in this thesis in connection with the rules of international law to which they relate, the general view being taken that treaties when duly ratified are expropria vigore municipal law, and whichever one of these classes they fall into they will be enforced as such by United States courts or executive officials.

At this point the subject matter of treaties will not be considered, but rather the general method of treaty enforcementthe measures which the United States has taken to prevent the infraction of treaties.

(2) The most important provision of this character is found in the constitution of the United States, which declares that, "this constitution and the laws of the United States which shall be made in pursuance thereof; and all treaties made or which shall be made under the authority of the United States shall be the supreme law of the land; and the judges in every state shall be bound thereby, anything in the constitution or law of any state to the contrary notwithstanding."'74

What agreements are treaties in the meaning of this provision is a question of municipal law. The constitution requires that two-thirds of the senate concur with the president in making treaties;75 it therefore seems that executive agreements, of which a considerable number have been concluded by the president alone, would not be "the supreme law of the land" in this sense. There is undoubtedly a limit to the scope of the treaty power, from the constitutional division of power between state and national government, but where the line is to be drawn has not been defined. It certainly appears to extend beyond the legislative power of congress." Ratification and proclamation also appear to be necessary before a treaty is valid in the sense of the constitution.78 Even when these conditions are complied with and from a technical standpoint the treaty is clearly within the terms of the constitutional provision there are important limitations to its full effect as municipal law in the sense of that term as adopted in this thesis.

In this connection the dual character of the obligation imposed by treaties must be borne in mind. A treaty primarily creates obligations between states. The recognized representative of the state, that is its government, may alone be held responsible for the infraction of treaties so far as the other contracting parties are concerned. This is the only function of 74 Constitution, art. 2, sec. 2, cl. 2. 75 Constitution, art. 2, sec. 2, cl. 2. 76 See Moore's Digest, 5;210-218.
