291 U.S.

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." 11

And Chief Justice Taney said upon the same subject: "But what are the police powers of a State? They are nothing more or less than the powers of government inherent in every sovereignty to the extent of its dominions. And whether a State passes a quarantine law, or a law to punish offences, or to establish courts of justice, or requiring certain instruments to be recorded, or to regulate commerce within its own limits, in every case it exercises the same powers; that is to say, the power of sovereignty, the power to govern men and things within the limits of its dominion. It is by virtue of this power that it legislates; and its authority to make regulations of commerce is as absolute as its power to pass health laws, except in so far as it has been restricted by the constitution of the United States." 12

13

Thus has this court from the early days affirmed that the power to promote the general welfare is inherent in government. Touching the matters committed to it by the Constitution, the United States possesses the power,1 as do the states in their sovereign capacity touching all subjects jurisdiction of which is not surrendered to the federal government, as shown by the quotations above given. These correlative rights, that of the citizen to exercise exclusive dominion over property and freely to contract about his affairs, and that of the state to regulate the use of property and the conduct of business, are always in collision. No exercise of the private right can be

imagined which will not in some respect, however slight, affect the public; no exercise of the legislative prerogative to regulate the conduct of the citizen which will not to some extent abridge his liberty or affect his property. But subject only to constitutional restraint the private right must yield to the public need.

14

The Fifth Amendment, in the field of federal activity,' and the Fourteenth, as respects state action,15 do not prohibit governmental regulation for the public welfare. They merely condition the exertion of the admitted power, by securing that the end shall be accomplished by methods consistent with due process. And the guaranty of due process, as has often been held, demands only that the law shall not be unreasonable, arbitrary or capricious, and that the means selected shall have a real and substantial relation to the object sought to be attained. It results that a regulation valid for one sort of business, or in given circumstances, may be invalid for another sort, or for the same business under other circumstances, because the reasonableness of each regulation depends upon the relevant facts.

The reports of our decisions abound with cases in which the citizen, individual or corporate, has vainly invoked the Fourteenth Amendment in resistance to necessary and appropriate exertion of the police power.

The court has repeatedly sustained curtailment of enjoyment of private property, in the public interest. The owner's rights may be subordinated to the needs of other private owners whose pursuits are vital to the paramount interests of the community.1 The state may control the

Laws passed for the suppression of immorality, in the interest of health, to secure fair trade practices, and to safeguard the interests of depositors in banks, have been found consistent with due process." These measures not
