Article VI, Clause 3:
The Senators and Representatives before mentioned, and the Members of the several State Legislatures, and all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution; but no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States.
Power of Congress in Respect to Oaths
Congress may require no other oath of fidelity to the Constitution, but it may add to this oath such other oath of office as its wisdom may require.1 It may not, however, prescribe a test oath as a qualification for holding office, such an act being in effect an ex post facto law,2 and the same rule holds in the case of the states.3
National Duties of State Officers
Commenting in The Federalist on the requirement that state officers, as well as members of the state legislatures, shall be bound by oath or affirmation to support the Constitution, Hamilton wrote:
Thus the legislatures, courts, and magistrates, of the respective members, will be incorporated into the operations of the national government as far as its just and constitutional authority extends; and it will be rendered auxiliary to the enforcement of its laws. 4 The younger Pinckney had expressed the same idea on the floor of the Philadelphia Convention:
They [the states] are the instruments upon which the Union must frequently depend for the support and execution of their powers. . . . 5 Indeed, the Constitution itself lays many duties, both positive and negative, upon the different organs of state government,6 and Congress may frequently add others, provided it does not require the state authorities to act outside their normal jurisdiction. Early congressional legislation contains many illustrations of such action by Congress.
The Judiciary Act of 17897 not only left the state courts in sole possession of a large part of the jurisdiction over controversies between citizens of different states and in concurrent possession of the rest, and by other sections state courts were authorized to entertain proceedings by the United States itself to enforce penalties and forfeitures under the revenue laws, examples of the principle that federal law is law to be applied by the state courts, but also any justice of the peace or other magistrates of any of the states were authorized to cause any offender against the United States to be arrested and imprisoned or bailed under the usual mode of process. From the beginning, Congress enacted hundreds of statutes that contained provisions authorizing state officers to enforce and execute federal laws.8 Pursuant to the same idea of treating state governmental organs as available to the national government for administrative purposes, the act of 1793 entrusted the rendition of fugitive slaves in part to national officials and in part to state officials and the rendition of fugitives from justice from one state to another exclusively to the state executives.9
With the rise of the doctrine of states' rights and of the equal sovereignty of the states with the National Government, the availability of the former as instruments of the latter in the execution of its power came to be questioned.10 In Prigg v. Pennsylvania ,11 decided in 1842, the constitutionality of the provision of the act of 1793 making it the duty of state magistrates to act in the return of fugitive slaves was challenged; and in Kentucky v. Dennison ,12 decided on the eve of the Civil War, similar objection was leveled against the provision of the same act which made it
the duty of the chief executive of a state to render up a fugitive from justice upon the demand of the chief executive of the state from which the fugitive had fled. The Court sustained both provisions, but upon the theory that the cooperation of the state authorities was purely voluntary. In Prigg , the Court, speaking by Justice Story, said that
while a difference of opinion has existed, and may exist still on the point, in different states, whether state magistrates are bound to act under it, none is entertained by this Court, that state magistrates may, if they choose, exercise that authority, unless prohibited by state legislation. 13 Subsequent cases confirmed the point that Congress could authorize willing state officers to perform such federal duties.14 Indeed, when Congress in the Selective Service Act of 1917 authorized enforcement to a great extent through state employees, the Court rejected
as too wanting in merit to require further notice the contention that the Act was invalid because of this delegation.15 State officials were frequently employed in the enforcement of the National Prohibition Act, and suits to abate nuisances as defined by the statute were authorized to be brought, in the name of the United States, not only by federal officials, but also by
any prosecuting attorney of any State or any subdivision thereof. 16
In Dennison , however, the Court held that, although Congress could delegate, it could not require performance of an obligation. The
duty of state executives in the rendition of fugitives from justice was construed to be declaratory of a
moral duty. Chief Justice Taney wrote for the Court:
The act does not provide any means to compel the execution of this duty, nor inflict any punishment for neglect or refusal on the part of the Executive of the State; nor is there any clause or provision in the Constitution which arms the Government of the United States with this power. Indeed, such a power would place every State under the control and dominion of the General Government, even in the administration of its internal concerns and reserved rights. And we think it clear that the Federal Government, under the Constitution, has no power to impose on a State officer, as such, any duty whatever, and compel him to perform it. . . . It is true, the Chief Justice conceded,
that in the early days of the Government, Congress relied with confidence upon the co-operation and support of the States, when exercising the legitimate powers of the General Government, and were accustomed to receive it, [but this, he explained, was] upon principles of comity, and from a sense of mutual and common interest, where no such duty was imposed by the Constitution. 17
Eighteen years later, in Ex parte Siebold ,18 the Court sustained the right of Congress, under Article I, § 4, paragraph 1 of the Constitution, to impose duties upon state election officials in connection with a congressional election and to prescribe additional penalties for the violation by such officials of their duties under state law. Although the doctrine of the holding was expressly confined to cases in which the National Government and the states enjoy
a concurrent power over the same subject matter, no attempt was made to catalogue such cases. Moreover, the outlook of Justice Bradley's opinion for the Court was decidedly nationalistic rather than dualistic, as is shown by the answer made to the contention of counsel
that the nature of sovereignty is such as to preclude the joint co-operation of two sovereigns, even in a matter in which they are mutually concerned . . . . 19 To this Justice Bradley replied:
As a general rule, it is no doubt expedient and wise that the operations of the State and national governments should, as far as practicable, be conducted separately, in order to avoid undue jealousies and jars and conflicts of jurisdiction and power. But there is no reason for laying this down as a rule of universal application. It should never be made to override the plain and manifest dictates of the Constitution itself. We cannot yield to such a transcendental view of state sovereignty. The Constitution and laws of the United States are the supreme law of the land, and to these every citizen of every State owes obedience, whether in his individual or official capacity. 20
Conflict thus developed early between these two doctrinal lines. But it was the Siebold line that prevailed. Enforcement of obligations upon state officials through mandamus or through injunctions was readily available, even when the state itself was immune, through the fiction of Ex parte Young ,21 under which a state official could be sued in his official capacity but without the immunities attaching to his official capacity. Although the obligations were, for a long period, in their origin based on the United States Constitution, the capacity of Congress to enforce statutory obligations through judicial action was little doubted.22 Nonetheless, it was only recently that the Court squarely overruled Dennison .
If it seemed clear to the Court in 1861, facing the looming shadow of a Civil War, that ‘the Federal Government, under the Constitution, has no power to impose on a State officer, as such, any duty whatever, and compel him to perform it,’ . . . basic constitutional principles now point as clearly the other way. 23 That case is doubly important, because the Court spoke not only to the Extradition Clause and the federal statute directly enforcing it, but it also enforced a purely statutory right on behalf of a Territory that could not claim for itself rights under the clause.24
Even as the Court imposes new federalism limits upon Congress’s powers to regulate the states as states, it has reaffirmed the principle that Congress may authorize the federal courts to compel state officials to comply with federal law, statutory as well as constitutional.
[T]he Supremacy Clause makes federal law paramount over the contrary positions of state officials; the power of federal courts to enforce federal law thus presupposes some authority to order state officials to comply. 25
No doubt, there is tension between the exercise of Congress’s power to impose duties on state officials26 and the developing doctrine under which the Court holds that Congress may not
commandeer state legislative or administrative processes in the enforcement of federal programs.27 However, the existence of the Supremacy Clause and the federal oath of office, as well as a body of precedent, indicates that coexistence of the two lines of principles will be maintained.
