The logic of the supremacy clause would seem to require that the powers of Congress be determined by the fair reading of the express and implied grants contained in the Constitution itself, without reference to the powers of the States. For a century after Marshall's death, however, the Court proceeded on the theory that the Tenth Amendment had the effect of withdrawing various matters of internal police from the reach of power expressly committed to Congress. This point of view was originally put forward in New York v. Miln,[6] which was first argued, but not decided, before Marshall's death. The Miln Case involved a New York statute which required the captains of vessels entering New York Harbor with aliens aboard to make a report in writing to the Mayor of the City, giving certain prescribed information. It might have been distinguished from Gibbons v. Ogden on the ground that the statute involved in the earlier case conflicted with an act of Congress, whereas the Court found that no such conflict existed in this case. But the Court was unwilling to rest its decision on that distinction. Speaking for the majority, Justice Barbour seized the opportunity to proclaim a new doctrine. He wrote: "But we do not place our opinion on this ground. We choose rather to plant ourselves on what we consider impregnable positions. They are these: That a State has the same undeniable and unlimited jurisdiction over all persons and things, within its territorial limits, as any foreign nation, where that jurisdiction is not surrendered or restrained by the Constitution of the United States. That, by virtue of this, it is not only the right, but the bounden and solemn duty of a State, to advance the safety, happiness and prosperity of its people, and to provide for its general welfare, by any and every act of legislation, which it may deem to be conducive to these ends; where the power over the particular subject, or the manner of its exercise is not surrendered or restrained, in the manner just stated. That all those powers which relate to merely municipal legislation, or what may, perhaps, more properly be called internal police, are not thus surrendered or restrained; and that, consequently, in relation to these, the authority of a State is complete, unqualified, and exclusive."[7] Justice Story, in dissent, stated that Marshall had heard the previous argument and reached the conclusion that the New York statute was unconstitutional.[8]
Status of the Issue Today
The conception of a "complete, unqualified and exclusive" police power residing in the States and limiting the powers of the National Government was endorsed by Chief Justice Taney ten years later in the License Cases.[9] In upholding State laws requiring licenses for the sale of alcoholic beverages, including those imported from other States or from foreign countries, he set up the Supreme Court as the final arbiter in drawing the line between the mutually exclusive, reciprocally limiting fields of power occupied by the National and State Governments.[10] This view has, in effect, and it would seem in theory also, been repudiated in recent cases upholding labor relations,[11] social security,[12] and fair labor standards acts[13] passed by Congress.
TASK OF THE SUPREME COURT UNDER THE CLAUSE
In applying the supremacy clause to subjects which have been regulated by Congress, the primary task of the Court is to ascertain whether a challenged State law is compatible with the policy expressed in the federal statute. When Congress condemns an act as unlawful, the extent and nature of the legal consequences of the condemnation are federal questions, the answers to which are to be derived from the statute and the policy which it has adopted. To the federal statute and policy, conflicting State law and policy must yield.[14] But Congress in enacting legislation within its constitutional authority will not be deemed to have intended to strike down a State statute to protect the health and safety of the public unless its purpose to do so is clearly manifested.[15]
When the United States performs its functions directly, through its own officers and employees, State police regulations clearly are inapplicable. In reversing the conviction of the governor of a national soldiers' home for serving oleomargarine in disregard of State law, the Court said that the federal officer was not "subject to the jurisdiction of the State in regard to those very matters of administration which are thus approved by Federal authority."[16] An employee of the Post Office Department is not required to submit to examination by State authorities concerning his competence and to pay a license fee before performing his official duty in driving a motor truck for transporting the mail.[17] To Arizona's complaint, in a suit to enjoin the construction of Boulder Dam, that her quasi-sovereignty would be invaded by the building of the dam without first securing approval of the State engineer as required by its laws, Justice Brandeis replied that, "if Congress has power to authorize the construction of the dam and reservoir, Wilbur [Secretary of the Interior] is under no obligation to submit the plans and specifications to the State Engineer for approval."[18]
FEDERAL INSTRUMENTALITIES AND THE STATE POLICE POWER
Federal instrumentalities and agencies have never enjoyed the same degree of immunity from State police regulation as from State taxation. The Court has looked to the nature of each regulation to determine whether it is compatible with the functions committed by Congress to the federal agency. This problem has arisen most often with reference to the applicability of State laws to the operation of national banks. Two correlative propositions have governed the decisions in these cases. The first was stated by Justice Miller in First National Bank v. Kentucky:[19] "[National banks are] subject to the laws of the State, and are governed in their daily course of business far more by the laws of the State than of the Nation. All their contracts are governed and construed by State laws. Their acquisition and transfer of property, their right to collect their debts, and their liability to be sued for debts, are all based on State law. It is only when the State law incapacitates the banks from discharging their duties to the government that it becomes unconstitutional."[20] In Davis v. Elmira Savings Bank,[21] the Court stated the second proposition thus: "National banks are instrumentalities of the Federal Government, created for a public purpose, and as such necessarily subject to the paramount authority of the United States. It follows that an attempt, by a State, to define their duties or control the conduct of their affairs is absolutely void, wherever such attempted exercise of authority expressly conflicts with the laws of the United States, and either frustrates the purpose of the national legislation or impairs the efficiency of these agencies of the Federal Government to discharge the duties, for the performance of which they were created."[22] Instructive, too, is a comparison of two other decisions. In the first,[23] the Court held that the fact that the Texas and Pacific Railway Company was a corporation organized under a statute of the United States did not remove it from the control of the Texas railroad commission as to business done wholly within the State. In the second,[24] the Court vetoed the attempt of Maryland to require a post office employee to cease driving a United States motor truck in the transportation of mail over a post road until he should obtain a license by submitting to examination before a State official and paying a fee. "Of course," said Justice Holmes, "an employee of the United States does not secure a general immunity from State law while acting in the course of his employment"; but this time the State went too far.
The extent to which States may go in regulating contractors who furnish goods or services to the Federal Government is not as clearly established as is their right to tax such dealers. In 1943, a closely divided Court sustained the refusal of the Pennsylvania Milk Control Commission to renew the license of a milk dealer who, in violation of State law, had sold milk to the United States for consumption by troops at an army camp located on land belonging to the State, at prices below the minima established by the Commission.[25] The majority was unable to find in Congressional legislation, or in the Constitution, unaided by Congressional enactment, any immunity from such price-fixing regulations. On the same day, a different majority held that California could not penalize a milk dealer for selling milk to the War Department at less than the minimum price fixed by State law where the sales and deliveries were made in a territory which had been ceded to the Federal Government by the State and were subject to the exclusive jurisdiction of the former.[26]
