PERPICH, GOVERNOR OF MINNESOTA, ET AL. v. DEPARTMENT OF DEFENSE ET AL.
CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE EIGHTH CIRCUIT
Argued March 27, 1990
Decided June 11, 1990
Since 1933, federal law has provided that persons enlisting in a State National Guard unit simultaneously enlist in the National Guard of the United States, a part of the Army. The enlistees retain their status as State Guard members unless and until ordered to active federal duty and revert to state status upon being relieved from federal service. The authority to order the Guard to federal duty was limited to periods of national emergency until 1952, when Congress broadly authorized orders "to active duty or active duty for training" without any emergency requirement, but provided that such orders could not be issued without the consent of the governor of the State concerned. After two State Governors refused to consent to federal training missions abroad for their Guard units, the gubernatorial consent requirement was partially repealed in 1986 by the "Montgomery Amendment," which provides that a governor cannot withhold consent with regard to active duty outside the United States because of any objection to the location, purpose, type, or schedule of such duty. The Governor of Minnesota and the State of Minnesota (hereinafter collectively referred to as the Governor) filed a complaint for injunctive relief, alleging, inter alia, that the Montgomery Amendment had prevented him from withholding his consent to a 1987 federal training mission in Central America for certain members of the State Guard, and that the Amendment violates the Militia Clauses of Article I, 8, of the Constitution, which authorize Congress to provide for (1) calling forth the militia to execute federal law, suppress insurrections, and repel invasions, and (2) organizing, arming, disciplining, and governing such part of the militia as may be employed in the federal service, reserving to the States the appointment of officers and the power to train the militia according to the discipline prescribed by Congress. The District Court rejected the Governor's challenge, holding that the Federal Guard was created pursuant to Congress' Article I, 8, power to raise and support armies; that the fact that Guard units also have an identity as part of the state militia does not limit Congress' plenary authority to train the units as it sees fit when the Guard is called to active federal service; and that, accordingly, the Constitution neither required the gubernatorial veto nor prohibited its withdrawal. The Court of Appeals affirmed. [496 U.S. 334, 335]
Article I's plain language, read as a whole, establishes that Congress may authorize members of the National Guard of the United States to be ordered to active federal duty for purposes of training outside the United States without either the consent of a State Governor or the declaration of a national emergency. Pp. 347-355.

JUSTICE STEVENS delivered the opinion of the Court.
The question presented is whether the Congress may authorize the President to order members of the National Guard to active duty for purposes of training outside the United States during peacetime without either the consent of a State Governor or the declaration of a national emergency.
In his complaint the Governor alleged that pursuant to a state statute the Minnesota National Guard is the organized militia of the State of Minnesota and that pursuant to a federal statute members of that militia "are also members of either the Minnesota unit of the Air National Guard of the United States or the Minnesota unit of the Army National Guard of the United States (hereinafter collectively referred to as the `National Guard of the United States')." App. 5. The complaint further alleged that the Montgomery Amendment had prevented the Governor from withholding his consent to a training mission in Central America for certain members of the Minnesota National Guard in January 1987, and prayed for an injunction against the implementation of any similar orders without his consent.
The District Judge rejected the Governor's challenge. He explained that the National Guard consists of "two overlapping, but legally distinct, organizations. Congress, under its constitutional authority to `raise and support armies' has created the National Guard of the United States, a federal organization comprised of state national guard units and their members." 666 F. Supp. 1319, 1320 (Minn. 1987). 4 The fact that these units also maintain an identity as [496 U.S. 334, 339] State National Guards, part of the militia described in Art. I, 8, of the Constitution, does not limit Congress' plenary authority to train the Guard "as it sees fit when the Guard is called to active federal service." Id., at 1324. He therefore concluded that "the gubernatorial veto found in 672(b) and 672(d) is not constitutionally required. Having created the gubernatorial veto as an accommodation to the states, rather than pursuant to a constitutional mandate, the Congress may withdraw the veto without violating the Constitution." Ibid.
A divided panel of the Court of Appeals for the Eighth Circuit reached a contrary conclusion. It read the Militia Clauses as preserving state authority over the training of the National Guard and its membership unless and until Congress "determined that there was some sort of exigency or extraordinary need to exert federal power." App. to Pet. for Cert. A92. Only in that event could the army power dissipate the authority reserved to the States under the Militia Clauses.
In response to a petition for rehearing en banc, the Court of Appeals vacated the panel decision and affirmed the judgment of the District Court. Over the dissent of two judges, the en banc court agreed with the District Court's conclusion that "Congress' army power is plenary and exclusive" and that the State's authority to train the militia did not conflict with congressional power to raise armies for the common defense and to control the training of federal reserve forces. 880 F.2d 11, 17-18 (1989).
Because of the manifest importance of the issue, we granted the Governor's petition for certiorari. 493 U.S. 1017 (1990). In the end, we conclude that the plain language [496 U.S. 334, 340] of Article I of the Constitution, read as whole, requires affirmance of the Court of Appeals' judgment. We believe, however, that a brief description of the evolution of the present statutory scheme will help to explain that holding.
Two conflicting themes, developed at the Constitutional Convention and repeated in debates over military policy during the next century, led to a compromise in the text of the Constitution and in later statutory enactments. On the one hand, there was a widespread fear that a national standing Army posed an intolerable threat to individual liberty and to the sovereignty of the separate States, 5 while, on the other hand, there was a recognition of the danger of relying on inadequately trained soldiers as the primary means of providing for the common defense. 6 Thus, Congress was authorized both to raise and support a national Army and also to organize "the Militia." [496 U.S. 334, 341]
In the early years of the Republic, Congress did neither. In 1792, it did pass a statute that purported to establish "an Uniform Militia throughout the United States," but its detailed command that every able-bodied male citizen between the ages of 18 and 45 be enrolled therein and equip himself with appropriate weaponry 7 was virtually ignored for more than a century, during which time the militia proved to be a decidedly unreliable fighting force. 8 The statute was finally repealed in 1901. 9 It was in that year that President Theodore Roosevelt declared: "Our militia law is obsolete and worthless." 10 The process of transforming "the National [496 U.S. 334, 342] Guard of the several States" into an effective fighting force then began.
The Dick Act divided the class of able-bodied male citizens between 18 and 45 years of age into an "organized militia" to be known as the National Guard of the several States, and the remainder of which was then described as the "reserve militia," and which later statutes have termed the "unorganized militia." The statute created a table of organization for the National Guard conforming to that of the Regular Army, and provided that federal funds and Regular Army instructors should be used to train its members. 11 It is undisputed that Congress was acting pursuant to the Militia Clauses of the Constitution in passing the Dick Act. Moreover, the legislative history of that Act indicates that Congress contemplated that the services of the organized militia would "be rendered only upon the soil of the United States or of its Territories." H. R. Rep. No. 1094, 57th Cong., 1st Sess., 22 (1902). In 1908, however, the statute was amended to provide [496 U.S. 334, 343] expressly that the Organized Militia should be available for service "either within or without the territory of the United States." 12
When the Army made plans to invoke that authority by using National Guard units south of the Mexican border, Attorney General Wickersham expressed the opinion that the Militia Clauses precluded such use outside the Nation's borders. 13 In response to that opinion and to the widening conflict in Europe, in 1916 Congress decided to "federalize" the National Guard. 14 In addition to providing for greater federal control and federal funding of the Guard, the statute required every guardsman to take a dual oath - to support the Nation as well as the States and to obey the President as well as the Governor - and authorized the President to draft members of the Guard into federal service. The statute expressly provided that the Army of the United States should include not only "the Regular Army," but also "the National [496 U.S. 334, 344] Guard while in the service of the United States," 15 and that when drafted into federal service by the President, members of the Guard so drafted should "from the date of their draft, stand discharged from the militia, and shall from said date be subject to" the rules and regulations governing the Regular Army. 111, 39 Stat. 211.
During World War I, the President exercised the power to draft members of the National Guard into the Regular Army. That power, as well as the power to compel civilians to render military service, was upheld in the Selective Draft Law Cases, 245 U.S. 366 (1918). 16 Specifically, in those cases, and in Cox v. Wood, 247 U.S. 3 (1918), the Court held that the plenary power to raise armies was "not qualified or restricted by the provisions of the militia clause." 17 [496 U.S. 334, 345]
The draft of the individual members of the National Guard into the Army during World War I virtually destroyed the Guard as an effective organization. The draft terminated the members' status as militiamen, and the statute did not provide for a restoration of their prewar status as members of the Guard when they were mustered out of the Army. This problem was ultimately remedied by the 1933 amendments to the 1916 Act. Those amendments created the "two overlapping but distinct organizations" described by the District Court - the National Guard of the various States and the National Guard of the United States.
Since 1933 all persons who have enlisted in a State National Guard unit have simultaneously enlisted in the National Guard of the United States. In the latter capacity they became a part of the Enlisted Reserve Corps of the Army, but unless and until ordered to active duty in the Army, they retained their status as members of a separate State Guard unit. Under the 1933 Act, they could be ordered into active service whenever Congress declared a national emergency and authorized the use of troops in excess of those in the Regular Army. The statute plainly described the effect of such an order:
Until 1952 the statutory authority to order National Guard units to active duty was limited to periods of national emergency. In that year, Congress broadly authorized orders to "active duty or active duty for training" without any emergency requirement, but provided that such orders could not be issued without gubernatorial consent. The National Guard units have under this plan become a sizable portion of the Nation's military forces; for example, "the Army National Guard provides 46 percent of the combat units and 28 percent of the support forces of the Total Army." 18 Apparently gubernatorial consents to training missions were routinely obtained until 1985, when the Governor of California refused to consent to a training mission for 450 members of the California National Guard in Honduras, and the Governor of Maine shortly thereafter refused to consent to a similar mission. Those incidents led to the enactment of the Montgomery Amendment and this litigation ensued. [496 U.S. 334, 347]
The Governor's attack on the Montgomery Amendment relies in part on the traditional understanding that "the Militia" can only be called forth for three limited purposes that do not encompass either foreign service or nonemergency conditions, and in part on the express language in the second Militia Clause reserving to the States "the Authority of training the Militia." The Governor does not, however, challenge the authority of Congress to create a dual enlistment program. 19 Nor does the Governor claim that membership in a State Guard unit - or any type of state militia - creates any sort of constitutional immunity from being drafted into the Federal Armed Forces. Indeed, it would be ironic to claim such immunity when every member of the Minnesota National Guard has voluntarily enlisted, or accepted a commission as an officer, in the National Guard of the United States and thereby become a member of the Reserve Corps of the Army.
The unchallenged validity of the dual enlistment system means that the members of the National Guard of Minnesota who are ordered into federal service with the National Guard of the United States lose their status as members of the state militia during their period of active duty. If that duty is a training mission, the training is performed by the Army in which the trainee is serving, not by the militia from which the member has been temporarily disassociated. "Each member of the Army National Guard of the United States or the Air National Guard of the United States who is ordered to active duty is relieved from duty in the National Guard of his State or Territory, or of Puerto Rico or the District of Columbia, as [496 U.S. 334, 348] the case may be, from the effective date of his order to active duty until he is relieved from that duty." 32 U.S.C. 325(a).
This change in status is unremarkable in light of the traditional understanding of the militia as a part-time, nonprofessional fighting force. In Dunne v. People, 94 Ill. 120 (1879), the Illinois Supreme Court expressed its understanding of the term "militia" as follows:
This conclusion is unaffected by the fact that prior to 1952 Guard members were traditionally not ordered into active service in peacetime or for duty abroad. That tradition is at least partially the product of political debate and political [496 U.S. 334, 349] compromise, but even if the tradition were compelled by the text of the Constitution, its constitutional aspect is related only to service by State Guard personnel who retain their state affiliation during their periods of service. There now exists a wholly different situation, in which the state affiliation is suspended in favor of an entirely federal affiliation during the period of active duty.
This view of the constitutional issue was presupposed by our decision in the Selective Draft Law Cases, 245 U.S. 366 (1918). Although the Governor is correct in pointing out that those cases were decided in the context of an actual war, the reasoning in our opinion was not so limited. After expressly noting that the 1916 Act had incorporated members of the National Guard into the National Army, the Court held that the Militia Clauses do not constrain the powers of Congress "to provide for the common Defence," to "raise and support Armies," to "make Rules for the Government and Regulation of the land and naval Forces," or to enact such laws as "shall be necessary and proper" for executing those powers. Id., at 375, 377, 381-384. The Court instead held that, far from being a limitation on those powers, the Militia Clauses are - as the constitutional text plainly indicates - additional grants of power to Congress.
The first empowers Congress to call forth the militia "to execute the Laws of the Union, suppress Insurrections and repel Invasions." We may assume that Attorney General Wickersham was entirely correct in reasoning that when a National Guard unit retains its status as a state militia, Congress could not "impress" the entire unit for any other purpose. Congress did, however, authorize the President to call forth the entire membership of the Guard into federal service during World War I, even though the soldiers who fought in France were not engaged in any of the three specified purposes. Membership in the militia did not exempt [496 U.S. 334, 350] them from a valid order to perform federal service, whether that service took the form of combat duty or training for such duty. 20 The congressional power to call forth the militia may in appropriate cases supplement its broader power to raise armies and provide for the common defense and general welfare, but it does not limit those powers. 21
The second Militia Clause enhances federal power in three additional ways. First, it authorizes Congress to provide for "organizing, arming and disciplining the Militia." It is by congressional choice that the available pool of citizens has been formed into organized units. Over the years, Congress has exercised this power in various ways, but its current choice of a dual enlistment system is just as permissible as the 1792 choice to have the members of the militia arm themselves. Second, the Clause authorizes Congress to provide for governing such part of the militia as may be employed in the service of the United States. Surely this authority encompasses continued training while on active duty. Finally, although the appointment of officers "and the Authority of training the Militia" is reserved to the States respectively, that limitation is, in turn, limited by the words "according to the discipline prescribed by Congress." If the discipline required for effective service in the Armed Forces of a global power requires training in distant lands, or distant skies, Congress has the authority to provide it. The subordinate [496 U.S. 334, 351] authority to perform the actual training prior to active duty in the federal service does not include the right to edit the discipline that Congress may prescribe for Guard members after they are ordered into federal service.
The Governor argues that this interpretation of the Militia Clauses has the practical effect of nullifying an important state power that is expressly reserved in the Constitution. We disagree. It merely recognizes the supremacy of federal power in the area of military affairs. 22 The Federal Government provides virtually all of the funding, the material, and the leadership for the State Guard units. The Minnesota unit, which includes about 13,000 members, is affected only slightly when a few dozen, or at most a few hundred, soldiers are ordered into active service for brief periods of time. 23 Neither the State's basic training responsibility, nor its ability to rely on its own Guard in state emergency situations, is significantly affected. Indeed, if the federal training mission were to interfere with the State Guard's capacity to respond to local emergencies, the Montgomery Amendment would permit the Governor to veto the proposed mission. 24 Moreover, [496 U.S. 334, 352] Congress has provided by statute that in addition to its National Guard, a State may provide and maintain at its own expense a defense force that is exempt from being drafted into the Armed Forces of the United States. See 32 U.S.C. 109(c). As long as that provision remains in effect, there is no basis for an argument that the federal statutory scheme deprives Minnesota of any constitutional entitlement to a separate militia of its own. 25 [496 U.S. 334, 353]
In light of the Constitution's more general plan for providing for the common defense, the powers allowed to the States by existing statutes are significant. As has already been mentioned, several constitutional provisions commit matters of foreign policy and military affairs to the exclusive control of the National Government. 26 This Court in Tarble's Case, 13 Wall. 397 (1872), had occasion to observe that the constitutional allocation of powers in this realm gave rise to a presumption that federal control over the Armed Forces was exclusive. 27 Were it not for the Militia Clauses, it might be [496 U.S. 334, 354] possible to argue on like grounds that the constitutional allocation of powers precluded the formation of organized state militia. 28 The Militia Clauses, however, subordinate any such structural inferences to an express permission while also subjecting state militia to express federal limitations. 29
We thus conclude that the Montgomery Amendment is not inconsistent with the Militia Clauses. In so doing, we of course do not pass upon the relative virtues of the various political choices that have frequently altered the relationship between the Federal Government and the States in the field of military affairs. This case does not raise any question concerning the wisdom of the gubernatorial veto established [496 U.S. 334, 355] in 1952 or of its partial repeal in 1986. We merely hold that because the former was not constitutionally compelled, the Montgomery Amendment is constitutionally valid.
The judgment of the Court of Appeals is affirmed.

[ Footnote 10 ] "Action should be taken in reference to the militia and to the raising of volunteer forces. Our militia law is obsolete and worthless. The organization and armament of the National Guard of the several States, which are treated as militia in the appropriations by the Congress, should be made identical with those provided for the regular forces. The obligations and duties of the Guard in time of war should be carefully defined, and a system established by law under which the method of procedure of raising volunteer forces should be prescribed in advance. It is utterly impossible in the excitement and haste of impending war to do this satisfactorily if the arrangements have not been made long beforehand. Provision should be made for utilizing in the first volunteer organizations called out the training of those citizens who have already had experience under arms, and especially for the selection in advance of the officers of any force which may be raised; for careful selection of the kind necessary is impossible after the outbreak of war."

[ Footnote 15 ] The National Defense Act of June 3, 1916, 39 Stat. 166, provided in part:
[ Footnote 16 ] "The possession of authority to enact the statute must be found in the clauses of the Constitution giving Congress power `to declare war; . . . to raise and support armies, but no appropriation of money to that use shall be for a longer term than two years; . . . to make rules for the government and regulation of the land and naval forces.' Article I, 8.

Article I, 8." 245 U.S., at 377 .
[ Footnote 17 ] "This result is apparent since on the face of the opinion delivered in those cases the constitutional power of Congress to compel the military service which the assailed law commanded was based on the following propositions: (a) That the power of Congress to compel military service and the duty of the citizen to render it when called for were derived from the authority given to Congress by the Constitution to declare war and to raise armies. (b) That those powers were not qualified or restricted by the provisions of the militia clause, and hence the authority in the exercise of the war power to raise armies and use them when raised was not subject to limitations as to use of the militia, if any, deduced from the militia [496 U.S. 334, 345] clause. And (c) that from these principles it also follows that the power to call for military duty under the authority to declare war and raise armies and the duty of the citizen to serve when called were coterminous with the constitutional grant from which the authority was derived and knew no limit deduced from a separate, and for the purpose of the war power, wholly incidental, if not irrelevant and subordinate, provision concerning the militia, found in the Constitution. Our duty to affirm is therefore made clear." 247 U.S., at 6 .

It is an essential aspect of traditional military policy of the United States. 32 U.S.C. 102. The State of Minnesota fully supports dual enlistment and has not challenged the concept in any respect." Reply Brief for Petitioners 9 (footnote omitted).
[ Footnote 21 ] Congress has by distinct statutes provided for activating the National Guard of the United States and for calling forth the militia, including the National Guards of the various States. See 10 U.S.C. 672-675 (authorizing executive officials to order reserve forces, including the National Guard of the United States and the Air National Guard of the United States, to active duty); 10 U.S.C. 331-333 (authorizing executive officials to call forth the militia of the States); 10 U.S.C. 3500, 8500 (authorizing executive officials to call forth the National Guards of the various States). When the National Guard units of the States are called forth, the orders "shall be issued through the governors of the States." 3500.
[ Footnote 22 ] This supremacy is evidenced by several constitutional provisions, especially the prohibition in Art. I, 10, of the Constitution, which states:
[ Footnote 23 ] According to the Governor, at most "only several hundred" of Minnesota's National Guard members "will be in federal training at any one time." Brief for Petitioners 41.
[ Footnote 24 ] The Montgomery Amendment deprives the Governors of the power to veto participation in a National Guard of the United States training mission on the basis of any objection to "the location, purpose, type, or schedule of such active duty." 10 U.S.C. 672(f). Governors may withhold their consent on other grounds. The Governor and the United States agree that if the federalization of the Guard would interfere with the State Guard's ability to address a local emergency, that circumstance would be a [496 U.S. 334, 352] valid basis for a gubernatorial veto. Brief for Petitioners 41; Brief for Respondents 9.
The Governor contends that the residual veto power is of little use. He predicates this argument, however, on a claim that the federal training program has so minimal an impact upon the State Guard that the veto is never necessary:
[ Footnote 25 ] The Governor contends that the state defense forces are irrelevant to this case because they are not subject to being called forth by the National Government and therefore cannot be militia within the meaning of the Constitution. We are not, however, satisfied that this argument is persuasive. First, the immunity of those forces from impressment into the national service appears - if indeed they have any such immunity - to be the consequence of a purely statutory choice, and it is not obvious why that choice should alter the constitutional status of the forces allowed the States. Second, although we do not believe it necessary to resolve the [496 U.S. 334, 353] issue, the Governor's construction of the relevant statute is subject to question. It is true that the state defense forces "may not be called, ordered, or drafted into the armed forces." 32 U.S.C. 109(c). It is nonetheless possible that they are subject to call under 10 U.S.C. 331-333, which distinguish the "militia" from the "armed forces," and which appear to subject all portions of the "militia" - organized or not - to call if needed for the purposes specified in the Militia Clauses. See n. 21, supra.
