In the early cases of Cherokee Nation v. Georgia[208] and Worcester v. Georgia[209] the Court, speaking by Chief Justice Marshall, held, first, that the Cherokee Nation was not a foreign state within the meaning of that clause of the Constitution which extends the judicial power of the United States to controversies "between a State or the citizens thereof and foreign states, citizens or subjects"; secondly, that: "The Constitution, by declaring treaties already made, as well as those to be made, to be the supreme law of the land, had adopted and sanctioned the previous treaties with the Indian nations, and consequently admits their rank among those powers who are capable of making treaties. The words 'treaty' and 'nation' are words of our own language, selected in our diplomatic and legislative proceedings, by ourselves, having each a definite and well understood meaning. We have applied them to Indians, as we have applied them to the other nations of the earth. They are applied to all in the same sense."[210]
Later cases established that the power to make treaties with the Indian tribes was coextensive with the power to make treaties with foreign nations;[211] that the States were incompetent to interfere with rights created by such treaties;[212] that as long as the United States recognized the national character of a tribe, its members were under the protection of treaties and of the laws of Congress and their property immune from taxation by a State;[213] that a stipulation in an Indian treaty that laws forbidding the introduction of liquors into Indian territory was operative without legislation, and binding on the courts although the territory was within an organized county of the States;[214] that an act of Congress contrary to a prior Indian treaty repealed it.[215]
Present Status of Indian Treaties
Today Indian treaties is a closed account in the Constitutional Law ledger. By a rider inserted in the Indian Appropriation Act of March 3, 1871 it was provided "That hereafter no Indian nation or tribe within the territory of the United States shall be acknowledged or recognized as an independent nation, tribe, or power with whom the United States may contract by treaty: Provided, further, that nothing herein contained shall be construed to invalidate or impair the obligation of any treaty heretofore lawfully made and ratified with any such Indian nation or tribe."[216] Subsequently, the power of Congress to withdraw or modify tribal rights previously granted by treaty has been invariably upheld. Thus the admission of Wyoming as a State was found to abrogate, pro tanto, a treaty guaranteeing certain Indians the right to hunt on unoccupied lands of the United States so long as game may be found thereon and to bring hunting by the Indians within the police power of the State.[217] Similarly, statutes modifying rights of members in tribal lands,[218] granting a right of way for a railroad through lands ceded by treaty to an Indian tribe,[219] or extending the application of revenue laws respecting liquor and tobacco over Indian territories, despite an earlier treaty exemption,[220] have been sustained. When, on the other hand, definite property rights have been conferred upon individual Indians, whether by treaty or under an act of Congress, they are protected by the Constitution to the same extent and in the same way as the private rights of other residents or citizens of the United States. Hence it was held that certain Indian allottees under an agreement according to which, in part consideration of their relinquishment of all their claim to tribal property, they were to receive in severalty allotments of lands which were to be nontaxable for a specified period, acquired vested rights of exemption from State taxation which were protected by the Fifth Amendment against abrogation by Congress.[221]
International Agreements Without Senate Approval
The capacity of the United States to enter into agreements with other nations is not exhausted in the treaty-making power. The Constitution recognizes a distinction between "treaties" and "agreements" or "compacts," but does not indicate what the difference is; and what difference there once may have been has been seriously blurred in practice within recent decades. The President's power to enter into agreements or compacts with other governments without consulting the Senate must be referred to his powers as organ of foreign relations and as Commander in Chief. From an early date, moreover, Congress has authorized executive agreements within the field of its powers, postal agreements, trade-mark and copyright agreements, reciprocal trade agreements. Executive agreements may also stem from treaties.[222]
ROUTINE EXECUTIVE AGREEMENTS
Many types of executive agreements comprise the ordinary daily grist of the diplomatic mill. Among these are such as apply to minor territorial adjustments, boundary rectifications, the policing of boundaries, the regulation of fishing rights, private pecuniary claims against another government or its nationals, in Story's words, "the mere private rights of sovereignty."[223] Crandall lists scores of such agreements entered into with other governments by the authorization of the President.[224] Such agreements are ordinarily directed to particular and comparatively trivial disputes and by the settlement the effect of these cease ipso facto to be operative. Also there are such time-honored diplomatic devices as the "protocol" which marks a stage in the negotiation of a treaty, and the modus vivendi, which is designed to serve as a temporary substitute for one. Executive agreements become of constitutional significance when they constitute a determinative factor of future foreign policy and hence of the country's destiny. Within recent decades, in consequence particularly of our participation in World War II and our immersion in the conditions of international tension which have prevailed both before and after this war, Presidents have entered into agreements with other governments some of which have approximated temporary alliances. It cannot be justly said, however, that in so doing they have acted without considerable support from precedent.
LAW-MAKING EXECUTIVE AGREEMENTS
An early instance of executive treaty-making was the agreement by which President Monroe in 1817 brought about a delimitation of armaments on the Great Lakes. The arrangement was effected by an exchange of notes, which nearly a year later was laid before the Senate with a query as to whether it was within the President's power, or whether advice and consent of the Senate were required. The Senate approved the agreement by the required two-thirds vote, and it was forthwith proclaimed by the President without there having been a formal exchange of ratifications.[225] Of a kindred type, and owing much to the President's capacity as Commander in Chief, was a series of agreements entered into with Mexico between 1882 and 1896 according each country the right to pursue marauding Indians across the common border.[226] Commenting on such an agreement, the Court remarked, a bit uncertainly: "While no act of Congress authorizes the executive department to permit the introduction of foreign troops, the power to give such permission without legislative assent was probably assumed to exist from the authority of the President as commander in chief of the military and naval forces of the United States. It may be doubted, however, whether such power could be extended to the apprehension of deserters [from foreign vessels] in the absence of positive legislation to that effect."[227] Justice Gray and three other Justices were of the opinion that such action by the President must rest upon express treaty or statute.[228]
