U.S. Supreme Court


198 U.S. 45

JOSEPH LOCHNER, Plff. in Err.,
No. 292.

Argued February 23, 24, 1905.
Decided April 17, 1905.

Mr. Justice Peckham, after making the foregoing statement of the facts, delivered the opinion of the court:

The indictment, it will be seen, charges that the plaintiff in error violated the 110th section of article 8, chapter 415, of the Laws of 1897, known as the labor law of the state of New York, in that he wrongfully and unlawfully required and permitted an employee working for him to work more than sixty hours in one week. There is nothing in any of the opinions delivered in this case, either in the supreme court or the court of appeals of the state, which construes the section, in using the word 'required,' as referring to any physical force being used to obtain the labor of an employee. It is assumed that the word means nothing more than the requirement arising from voluntary contract for such labor in excess of the number of hours specified in the statute. There is no pretense in any of the opinions that the statute was intended to meet a case of involuntary labor in any form. All the opinions assume that there is no real distinction, so far as this question is concerned, between the words 'required' and 'permitted.' The mandate of the statute, that 'no employee shall be required or permitted to work,' is the substantial equivalent of an enactment that 'no employee shall contract or agree to work,' more than ten hours per day; and, as there is no provision for special emergencies, the statute is mandatory in all cases. It is not an act merely fixing the number of hours which shall constitute a legal day's work, but an absolute prohibition upon the employer permitting, under any circumstances, more than ten hours' work to be done in his establishment. The employee may desire to earn the extra money which would arise from his working more than the prescribed time, but this statute forbids the employer from permitting the employee to earn it.

The statute necessarily interferes with the right of contract between the employer and employees, concerning the number of hours in which the latter may labor in the bakery of the employer. The general right to make a contract in relation to his business is part of the liberty of the individual protected by the 14th Amendment of the Federal Constitution. Allgeyer v. Louisiana, 165 U.S. 578 , 41 L. ed. 832, 17 Sup. Ct. Rep. 427. Under that provision no state can deprive any person of life, liberty, or property without due process of law. The right to purchase or to sell labor is part of the liberty protected by this amendment, unless there are circumstances which exclude the right. There are, however, certain powers, existing in the sovereignty of each state in the Union, somewhat vaguely termed police powers, the exact description and limitation of which have not been attempted by the courts. Those powers, broadly stated, and without, at present, any attempt at a more specific limitation, relate to the safety, health, morals, and general welfare of the public. Both property and liberty are held on such reasonable conditions as may be imposed by the governing power of the state in the exercise of those powers, and with such conditions the 14th Amendment was not designed to interfere. Mugler v. Kansas, 123 U.S. 623 , 31 L. ed. 205, 8 Sup. Ct. Rep. 273; Re Kemmler, 136 U.S. 436 , 34 L. ed. 519, 10 Sup. Ct. Rep. 930; Crowley v. Christensen, 137 U.S. 86 , 34 L. ed. 620, 11 Sup. Ct. Rep. 13; Re Converse, 137 U.S. 624 , 34 L. ed. 796, 11 Sup. Ct. Rep. 191.

The state, therefore, has power to prevent the individual from making certain kinds of contracts, and in regard to them the Federal Constitution offers no protection. If the contract be one which the state, in the legitimate exercise of its police power, has the right to prohibit, it is not prevented from prohibiting it by the 14th Amendment. Contracts in violation of a statute, either of the Federal or state government, or a contract to let one's property for immoral purposes, or to do any other unlawful act, could obtain no protection from the Federal Constitution, as coming under the liberty of [198 U.S. 45, 54]   person or of free contract. Therefore, when the state, by its legislature, in the assumed exercise of its police powers, has passed an act which seriously limits the right to labor or the right of contract in regard to their means of livelihood between persons who are sui juris (both employer and employee), it becomes of great importance to determine which shall prevail,-the right of the individual to labor for such time as he may choose, or the right of the state to prevent the individual from laboring, or from entering into any contract to labor, beyond a certain time prescribed by the state.

This court has recognized the existence and upheld the exercise of the police powers of the states in many cases which might fairly be considered as border ones, and it has, in the course of its determination of questions regarding the asserted invalidity of such statutes, on the ground of their violation of the rights secured by the Federal Constitution, been guided by rules of a very liberal nature, the application of which has resulted, in numerous instances, in upholding the validity of state statutes thus assailed. Among the later cases where the state law has been upheld by this court is that of Holden v. Hardy, 169 U.S. 366 , 42 L. ed. 780, 18 Sup. Ct. Rep. 383. A provision in the act of the legislature of Utah was there under consideration, the act limiting the employment of workmen in all underground mines or workings, to eight hours per day, 'except in cases of emergency, where life or property is in imminent danger.' It also limited the hours of labor in smelting and other institutions for the reduction or refining of ores or metals to eight hours per day, except in like cases of emergency. The act was held to be a valid exercise of the police powers of the state. A review of many of the cases on the subject, decided by this and other courts, is given in the opinion. It was held that the kind of employment, mining, smelting, etc., and the character of the employees in such kinds of labor, were such as to make it reasonable and proper for the state to interfere to prevent the employees from being constrained by the rules laid down by the proprietors in regard to labor. The following citation from the observations of the supreme court of Utah in that case was made by the judge writing the opinion of this court, and approved: 'The law in question is confined to the protection of that class of people engaged in labor in underground mines, and in smelters and other works wherein ores are reduced and refined. This law applies only to the classes subjected by their employment to the peculiar conditions and effects attending underground mining and work in smelters, and other works for the reduction and refining of ores. Therefore it is not necessary to discuss or decide whether the legislature can fix the hours of labor in other employments.'

It will be observed that, even with regard to that class of labor, the Utah statute provided for cases of emergency wherein the provisions of the statute would not apply. The statute now before this court has no emergency clause in it, and, if the statute is valid, there are no circumstances and no emergencies under which the slightest violation of the provisions of the act would be innocent. There is nothing in Holden v. Hardy which covers the case now before us.


It must, of course, be conceded that there is a limit to the valid exercise of the police power by the state. There is no dispute concerning this general proposition. Otherwise the 14th Amendment would have no efficacy and the legislatures of the states would have unbounded power, and it would be enough to say that any piece of legislation was enacted to conserve the morals, the health, or the safety of the people; such legislation would be valid, no matter how absolutely without foundation the claim might be. The claim of the police power would be a mere pretext,- become another and delusive name for the supreme sovereignty of the state to be exercised free from constitutional restraint. This is not contended for. In every case that comes before this court, therefore, where legislation of this character is concerned, and where the protection of the Federal Constitution is sought, the question necessarily arises: Is this a fair, reasonable, and appropriate exercise of the police power of the state, or is it an unreasonable, unnecessary, and arbitrary interference with the right of the individual to his personal liberty, or to enter into those contracts in relation to labor which may seem to him appropriate or necessary for the support of himself and his family? Of course the liberty of contract relating to labor includes both parties to it. The one has as much right to purchase as the other to sell labor.

This is not a question of substituting the judgment of the court for that of the legislature. If the act be within the power of the state it is valid, although the judgment of the court might be totally opposed to the enactment of such a law. But the question would still remain: Is it within the police power of the state? and that question must be answered by the court.

The question whether this act is valid as a labor law, pure and simple, may be dismissed in a few words. There is no reasonable ground for interfering with the liberty of person or the right of free contract, by determining the hours of labor, in the occupation of a baker. There is no contention that bakers as a class are not equal in intelligence and capacity to men in other trades or manual occupations, or that they are not able to assert their rights and care for themselves without the protecting arm of the state, interfering with their independence of judgment and of action. They are in no sense wards of the state. Viewed in the light of a purely labor law, with no reference whatever to the question of health, we think that a law like the one before us involves neither the safety, the morals, nor the welfare, of the public, and that the interest of the public is not in the slightest degree affected by such an act. The law must be upheld, if at all, as a law pertaining to the health of the individual engaged in the occupation of a baker. It does not affect any other portion of the public than those who are engaged in that occupation. Clean and wholesome bread does not depend upon whether the baker works but ten hours per day or only sixty hours a week. The limitation of the hours of labor does not come within the police power on that ground.

It is a question of which of two powers or rights shall prevail,-the power of the state to legislate or the right of the individual to liberty of person and freedom of contract. The mere assertion that the subject relates, though but in a remote degree, to the public health, does not necessarily render the enactment valid. The act must have a more direct relation, as a means to an end, and the end itself must be appropriate and legitimate, before an act can be held to be valid which interferes with the general right of an individual to be free in his person and in his power to contract in relation to his own labor.

This case has caused much diversity of opinion in the state courts. In the supreme court two of the five judges composing the court dissented from the judgment affirming the validity of the act. In the court of appeals three of the seven judges also dissented from the judgment upholding the statute. Although found in what is called a labor law of the state, the court of appeals has upheld the act as one relating to the public health,-in other words, as a health law. One of the judges of the court of appeals, in upholding the law, stated that, in his opinion, the regulation in question could not be sustained unless they were able to say, from common knowledge, that working in a bakery and candy factory was an unhealthy employment. The judge held that, while the evidence was not uniform, it still led him to the conclusion that the occupation of a baker or confectioner was unhealthy and tended to result in diseases of the respiratory organs. Three of the judges dissented from that view, and they thought the occupation of a baker was not to such an extent unhealthy as to warrant the interference of the legislature with the liberty of the individual.

We think the limit of the police power has been reached and passed in this case. There is, in our judgment, no reasonable foundation for holding this to be necessary or appropriate as a health law to safeguard the public health, or the health of the individuals who are following the trade of a baker. If this statute be valid, and if, therefore, a proper case is made out in which to deny the right of an individual, sui juris, as employer or employee, to make contracts for the labor of the latter under the protection of the provisions of the Federal Constitution, there would seem to be no length to which legislation of this nature might not go.


It is impossible for us to shut our eyes to the fact that many of the laws of this character, while passed under what is claimed to be the police power for the purpose of protecting the public health or welfare, are, in reality, passed from other motives. We are justified in saying so when, from the character of the law and the subject upon which it legislates, it is apparent that the public health or welfare bears but the most remote relation to the law. The purpose of a statute must be determined from the natural and legal effect of the language employed; and whether it is or is not repugnant to the Constitution of the United States must be determined from the natural effect of such statutes when put into operation, and not from their proclaimed purpose. Minnesota v. Barber, 136 U.S. 313 , 34 L. ed. 455, 3 Inters. Com. Rep. 185, 10 Sup. Ct. Rep. 862; Brimmer v. Rebman, 138 U.S. 78 , 34 L. ed. 862, 3 Inters. Com. Rep. 485, 11 Sup. Ct. Rep. 213. The court looks beyond the mere letter of the law in such cases. Yick Wo v. Hopkins, 118 U.S. 356 , 30 L. ed. 220, 6 Sup. Ct. Rep. 1064

It is manifest to us that the limitation of the hours of labor as provided for in this section of the statute under which the indictment was found, and the plaintiff in error convicted, has no such direct relation to, and no such substantial effect upon, the health of the employee, as to justify us in regarding the section as really a health law. It seems to us that the real object and purpose were simply to regulate the hours of labor between the master and his employees (all being men, Sui juris), in a private business, not dangerous in any degree to morals, or in any real and substantial degree to the health of the employees. Under such circumstances the freedom of master and employee to contract with each other in relation to their employment, and in defining the same, cannot be prohibited or interfered with, without violating the Federal Constitution.

The judgment of the Court of Appeals of New York, as well as that of the Supreme Court and of the County Court of Oneida County, must be reversed and the case remanded to the County Court for further proceedings not inconsistent with this opinion.


Mr. Justice Harlan (with whom Mr. Justice White and Mr. Justice Day concurred) dissenting:

While this court has not attempted to mark the precise boundaries of what is called the police power of the state, the existence of the power has been uniformly recognized, equally by the Federal and State courts.

All the cases agree that this power extends at least to the protection of the lives, the health, and the safety of the public against the injurious exercise by any citizen of his own rights.


Speaking generally, the state, in the exercise of its powers, may not unduly interfere with the right of the citizen to enter into contracts that may be necessary and essential in the enjoyment of the inherent rights belonging to everyone, among which rights is the right 'to be free in the enjoyment of all his faculties, to be free to use them in all lawful ways, to live and work where he will, to earn his livelihood by any lawful calling, to pursue any livelihood or avocation.' This was declared in Allgeyer v. Louisiana, 165 U.S. 578, 589 , 41 S. L. ed. 832, 835, 17 Sup. Ct. Rep. 427, 431. But in the same case it was conceded that the right to contract in relation to persons and property, or to do business, within a state, may be 'regulated, and sometimes prohibited, when the contracts or business conflict with the policy of the state as contained in its statutes.' (p. 591, L. ed. p. 836, Sup. Ct. Rep. p. 432.)

So, as said in Holden v. Hardy, 169 U.S. 366, 391 , 42 S. L. ed. 780, 790, 18 Sup. Ct. Rep. 383, 388: 'This right of contract, however, is itself subject to certain limitations which the state may lawfully impose in the exercise of its police powers. While this power is inherent in all governments, it has doubtless been greatly expanded in its application during the past century, owing to an enormous increase in the number of occupations which are dangerous, or so far detrimental, to the health of employees as to demand special precautions for their well-being and protection, or the safety of adjacent property. While this court has held, notably in the cases Davidson v. New Orleans, 96 U.S. 97 , 24 L. ed. 616, and Yick Wo. v. Hopkins, 118 U.S. 356 , 30 L. ed. 220, 6 Sup. Ct. Rep. 1064, that the police power cannot be put forward as an excuse for oppressive and unjust legislation, it may be lawfully resorted to for the purpose of preserving the public health, safety, or morals, or the abatement of public nuisances; and a large discretion 'is necessarily vested in the legislature to determine, not only what the interests of the public required, but what measures are necessary for the protection of such interests.' Lawton v. Steele, 152 U.S. 133, 136 , 38 S. L. ed. 385, 388, 14 Sup. Ct. Rep. 499, 501.' Referring to the limitations placed by the state upon the hours of workmen, the court in the same case said (p. 395, L. ed. p. 792, Sup. Ct. Rep. p. 389): 'These employments, when too long pursued, the legislature has judged to be detrimental to the health of the employees, and, so long as there are reasonable grounds for believing that this is so, its decision upon this subject cannot be reviewed by the Federal courts.'


I take it to be firmly established that what is called the liberty of contract may, within certain limits, be subjected to regulations designed and calculated to promote the general welfare, or to guard the public health, the public morals, or the public safety. 'The liberty secured by the Constitution of the United States to every person within its jurisdiction does not import.' this court has recently said, 'an absolute right in each person to be at all times and in all circumstances wholly freed from restraint. There are manifold restraints to which every person is necessarily subject for the common good.' Jacobson v. Massachusetts, 197 U.S. 11 , 25 Sup. Ct. Rep. 358, 49 L. ed. Granting, then, that there is a liberty of contract which cannot be violated even under the sanction of direct legislative enactment, but assuming, as according to settled law we may assume, that such liberty of contract is subject to such regulations as the state may reasonably prescribe for the common good and the well-being of society, what are the conditions under which the judiciary may declare such regulations to be in excess of legislative authority and void? Upon this point there is no room for dispute; for the rule is universal that a legislative enactment, Federal or state, is never to be disregarded or held invalid unless it be, beyond question, plainly and palpably in excess of legislative power.


Let these principles be applied to the present case. By the statute in question it is provided that 'no employee shall be required, or permitted, to work in a biscuit, bread, or cake bakery, or confectionery establishment, more than sixty hours in any one week, or more than ten hours in any one day, unless for the purpose of making a shorter work day on the last day of the week; nor more hours in any one week than will make an average of ten hours per day for the number of days during such week in which such employee shall work.'

It is plain that this statute was enacted in order to protect the physical well-being of those who work in bakery and confectionery establishments. It may be that the statute had its origin, in part, in the belief that employers and employees in such establishments were not upon an equal footing, and that the necessities of the latter often compelled them to submit to such exactions as unduly taxed their strength. Be this as it may, the statute must be taken as expressing the belief of the people of New York that, as a general rule, and in the case of the average man, labor in excess of sixty hours during a week in such establishments may endanger the health of those who thus labor. Whether or not this be wise legislation it is not the province of the court to inquire. Under our systems of government the courts are not concerned with the wisdom or policy of legislation. So that, in determining the question of power to interfere with liberty of contract, the court may inquire whether the means devised by the state are germane to an end which may be lawfully accomplished and have a real or substantial relation to the protection of health, as involved in the daily work of the persons, male and female, engaged in bakery and confectionery establishments. But when this inquiry is entered upon I find it impossible, in view of common experience, to say that there is here no real or substantial relation between the means employed by the state and the end sought to be accomplished by its legislation. Mugler v. Kansas, 123 U.S. 623, 661 , 31 S. L. ed. 205, 210, 8 Sup. Ct. Rep. 273. Nor can I say that the statute has no appropriate or direct connection with that protection to health which each state owes to her citizens (Patterson v. Kentucky, 97 U.S. 501 , 24 L. ed. 1115); or that it is not promotive of the health of the employees in question ( Holden v. Hardy, 169 U.S. 366, 391 , 42 S. L. ed. 780, 790, 18 Sup. Ct. Rep. 383; Lawton v. Steele, 152 U.S. 133, 139 , 38 S. L. ed. 385, 389, 14 Sup. Ct. Rep. 499); or that the regulation prescribed by the state is utterly unreasonable and extravagant or wholly arbitrary (Gundling v. Chicago, 177 U.S. 183, 188 , 44 S. L. ed. 725, 728, 20 Sup. Ct. Rep. 633). Still less can I say that the statute is, beyond question, a plain, palpable invasion of rights secured by the fundamental law. Jacobson v. Massachusetts, 196 U.S. 11 , ante, p. 358, 25 Sup. Ct. Rep. 358. Therefore I submit that this court will transcend its functions if it assumes to annul the statute of New York. It must be remembered that this statute does not apply to all kinds of business. It applies only to work in bakery and confectionery establishments, in which, as all know, the air constantly breathed by workmen is not as pure and healthful as that to be found in some other establishments or out of doors.

Professor Hirt in his treatise on the 'Diseases of the Workers' has said: 'The labor of the bakers is among the hardest and most laborious imaginable, because it has to be performed under conditions injurious to the health of those engaged in it. It is hard, very hard, work, not only because it requires a great deal of physical exertion in an overheated workshop and during unreasonably long hours, but more so because of the erratic demands of the public, compelling the baker to perform the greater part of his work at night, thus depriving him of an opportunity to enjoy the necessary rest and sleep,-a fact which is highly injurious to his health.' Another writer says: 'The constant inhaling of flour dust causes inflammation of the lungs and of the bronchial tubes. The eyes also suffer through this dust, which is responsible for the many cases of running eyes among the bakers. The long hours of toil to which all bakers are subjected produce rheumatism, cramps, and swollen legs. The intense heat in the workshops induces the workers to resort to cooling drinks, which, together with their habit of exposing the greater part of their bodies to the change in the atmosphere, is another source of a number of diseases of various organs. Nearly all bakers are palefaced and of more delicate health than the workers of other crafts, which is chiefly due to their hard work and their irregular and unnatural mode of living, whereby the power of resistance against disease is greatly diminished. The average age of a baker is below that of other workmen; they seldom live over their fiftieth year, most of them dying between the ages of forty and fifty. During periods of epidemic diseases the bakers are generally the first to succumb to the disease, and the number swept away during such periods far exceeds the number of other crafts in comparison to the men employed in the respective industries. When, in 1720, the plague visited the city of Marseilles, France, every baker in the city succumbed to the epidemic, which caused considerable excitement in the neighboring cities and resulted in measures for the sanitary protection of the bakers.'

In the Eighteenth Annual Report by the New York Bureau of Statistics of Labor it is stated that among the occupations involving exposure to conditions that interfere with nutrition is that of a baker. (p. 52.) In that Report it is also stated that, 'from a social point of view, production will be increased by any change in industrial organization which diminishes the number of idlers, paupers, and criminals. Shorter hours of work, by allowing higher standards of comfort and purer family life, promise to enhance the industrial efficiency of the wage-working class,-improved health, longer life, more content and greater intelligence and inventiveness.' (p. 82.)

Statistics show that the average daily working time among workingmen in different countries is, in Australia, eight hours; in Great Britain, nine; in the United States, nine and three-quarters; in Denmark, nine and three-quarters; in Norway, ten; Sweden, France, and Switzerland, ten and one-half; Germany, ten and one-quarter; Belgium, Italy, and Austria, eleven; and in Russia, twelve hours.

We judicially know that the question of the number of hours during which a workman should continuously labor has been, for a long period, and is yet, a subject of serious consideration among civilized peoples, and by those having special knowledge of the laws of health. Suppose the statute prohibited labor in bakery and confectionery establishments in excess of eighteen hours each day. No one, I take it, could dispute the power of the state to enact such a statute. But the statute [198 U.S. 45, 72]   before us does not embrace extreme or exceptional cases. It may be said to occupy a middle ground in respect of the hours of labor. What is the true ground for the state to take between legitimate protection, by legislation, of the public health and liberty of contract is not a question easily solved, nor one in respect of which there is or can be absolute certainty. There are very few, if any, questions in political economy about which entire certainty may be predicated. One writer on relation of the state to labor has well said: 'The manner, occasion, and degree in which the state may interfere with the industrial freedom of its citizens is one of the most debatable and difficult questions of social science.' Jevons, 33.

We also judicially know that the number of hours that should constitute a day's labor in particular occupations involving the physical strength and safety of workmen has been the subject of enactments by Congress and by nearly all of the states. Many, if not most, of those enactments fix eight hours as the proper basis of a day's labor.

I do not stop to consider whether any particular view of this economic question presents the sounder theory. What the precise facts are it may be difficult to say. It is enough for the determination of this case, and it is enough for this court to know, that the question is one about which there is room for debate and for an honest difference of opinion. There are many reasons of a weighty, substantial character, based upon the experience of mankind, in support of the theory that, all things considered, more than ten hours' steady work each day, from week to week, in a bakery or confectionery establishment, may endanger the health and shorten the lives of the workmen, thereby diminishing their physical and mental capacity to serve the state and to provide for those dependent upon them.


We are reminded by counsel that it is the solemn duty of the courts in cases before them to guard the constitutional rights of the citizen against merely arbitrary power. That is unquestionably true. But it is equally true-indeed, the public interests imperatively demand-that legislative enactments should be recognized and enforced by the courts as embodying the will of the people, unless they are plainly and palpably beyond all question in violation of the fundamental law of the Constitution.' Atkin v. Kansas, 191 U.S. 207, 223 , 48 S. L. ed. 148, 158, 24 Sup. Ct. Rep. 124, 128.

The judgment, in my opinion, should be affirmed.

Mr. Justice Holmes dissenting:

I regret sincerely that I am unable to agree with the judg- [198 U.S. 45, 75]   ment in this case, and that I think it my duty to express my dissent.

This case is decided upon an economic theory which a large part of the country does not entertain. If it were a question whether I agreed with that theory, I should desire to study it further and long before making up my mind. But I do not conceive that to be my duty, because I strongly believe that my agreement or disagreement has nothing to do with the right of a majority to embody their opinions in law. It is settled by various decisions of this court that state constitutions and state laws may regulate life in many ways which we as legislators might think as injudicious, or if you like as tyrannical, as this, and which, equally with this, interfere with the liberty to contract. Sunday laws and usury laws are ancient examples. A more modern one is the prohibition of lotteries. The liberty of the citizen to do as he likes so long as he does not interfere with the liberty of others to do the same, which has been a shibboleth for some well-known writers, is interfered with by school laws, by the Postoffice, by every state or municipal institution which takes his money for purposes thought desirable, whether he likes it or not. The 14th Amendment does not enact Mr. Herbert Spencer's Social Statics. The other day we sustained the Massachusetts vaccination law. Jacobson v. Massachusetts, 197 U.S. 11 , 25 Sup. Ct. Rep. 358, 49 L. ed. _____ United States and state statutes and decisions cutting down the liberty to contract by way of combination are familiar to this court. Northern Securities Co. v. United States, 193 U.S. 197 , 48 L. ed. 679, 24 Sup. Ct. Rep. 436. Two years ago we upheld the prohibition of sales of stock on margins, or for future delivery, in the Constitution of California. Otis v. Parker, 187 U.S. 606 , 47 L. ed. 323, 23 Sup. Ct. Rep. 168. The decision sustaining an eight-hour law for miners is still recent. Holden v. Hardy, 169 U.S. 366 , 42 L. ed. 780, 18 Sup. Ct. Rep. 383. Some of these laws embody convictions or prejudices which judges are likely to share. Some may not. But a Constitution is not intended to embody a particular economic theory, whether of paternalism and the organic relation of the citizen to the state or of laissez faire.  It is made for people of fundamentally differing views, and the accident of our finding certain opinions natural and familiar, or novel, and even shocking, ought not to conclude our judgment upon the question whether statutes embodying them conflict with the Constitution of the United States.

General propositions do not decide concrete cases. The decision will depend on a judgment or intuition more subtle than any articulate major premise. But I think that the proposition just stated, if it is accepted, will carry us far toward the end. Every opinion tends to become a law. I think that the word 'liberty,' in the 14th Amendment, is perverted when it is held to prevent the natural outcome of a dominant opinion, unless it can be said that a rational and fair man necessarily would admit that the statute proposed would infringe fundamental principles as they have been understood by the traditions of our people and our law. It does not need research to show that no such sweeping condemnation can be passed upon the statute before us. A reasonable man might think it a proper measure on the score of health. Men whom I certainly could not pronounce unreasonable would uphold it as a first instalment of a general regulation of the hours of work. Whether in the latter aspect it would be open to the charge of inequality I think it unnecessary to discuss.
