LOCHNER v. PEOPLE OF STATE OF NEW YORK
198 U.S. 45 (1905)

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

[In the Public Domain. Source: FindLaw]


Mr. Justice Peckham . . . 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 . . .) 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 . . . ; Re Kemmler . . . ; Crowley v. Christensen . . . ; Re Converse . . .)

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 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. . . .

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. . . . We think that there can be no fair doubt that the trade of a baker, in and of itself, is not an unhealthy one to that degree which would authorize the legislature to interfere with the right to labor, and with the right of free contract on the part of the individual, either as employer or employee In looking through statistics regarding all trades and occupations, it may be true that the trade of a baker does not appear to be as healthy as some other trades, and is also vastly more healthy than still others. To the common understanding the trade of a baker has never been regarded as an unhealthy one. Very likely physicians would not recommend the exercise of that or of any other trade as a remedy for ill health. Some occupations are more healthy than others, but we think there are none which might not come under the power of the legislature to supervise and control the hours of working therein, if the mere fact that the occupation is not absolutely and perfectly healthy is to confer that right upon the legislative department of the government. It might be safely affirmed that almost all occupations more or less affect the health. There must be more than the mere fact of the possible existence of some small amount of unhealthiness to warrant legislative interference with liberty. It is unfortunately true that labor, even in any department, may possibly carry with it the seeds of unhealthiness. But are we all, on that account, at the mercy of legislative majorities? A printer, a tinsmith, a locksmith, a carpenter, a cabinetmaker, a dry goods clerk, a bank’s, a lawyer’s, or a physician’s clerk, or a clerk in almost any kind of business, would all come under the power of the legislature, on this assumption. No trade, no occupation, no mode of earning one’s living, could escape this all-pervading power, and the acts of the legislature in limiting the hours of labor in all employments would be valid, although such limitation might seriously cripple the ability of the laborer to support himself and his family. In our large cities there are many buildings into which the sun penetrates for but a short time in each day, and these buildings are occupied by people carrying on the business of bankers, brokers, lawyers, real estate, and many other kinds of business, aided by many clerks, messengers, and other employees. Upon the assumption of the validity of this act under review, it is not possible to say that an act, prohibiting lawyers’ or bank clerks, or others, from contracting to labor for their employers more than eight hours a day would be invalid. It might be said that it is unhealthy to work more than that number of hours in an apartment lighted by artificial light during the working hours of the day; that the occupation of the bank clerk, the lawyer’s clerk, the real estate clerk, or the broker’s clerk, in such offices is therefore unhealthy, and the legislature, in its paternal wisdom, must, therefore, have the right to legislate on the subject of, and to limit, the hours for such labor; and, if it exercises that power, and its validity be questioned, it is sufficient to say, it has reference to the public health; it has reference to the health of the employees condemned to labor day after day in buildings where the sun never shines; it is a health law, and therefore it is valid, and cannot be questioned by the courts.

It is also urged, pursuing the same line of argument, that it is to the interest of the state that its population should be strong and robust, and therefore any legislation which may be said to tend to make people healthy must be valid as health laws, enacted under the police power. If this be a valid argument and a justification for this kind of legislation, it follows that the protection of the Federal Constitution from undue interference with liberty of person and freedom of contract is visionary, wherever the law is sought to be justified as a valid exercise of the police power. Scarcely any law but might find shelter under such assumptions, and conduct, properly so called, as well as contract, would come under the restrictive sway of the legislature. Not only the hours of employees, but the hours of employers, could be regulated, and doctors, lawyers, scientists, all professional men, as well as athletes and artisans, could be forbidden to fatigue their brains and bodies by prolonged hours of exercise, lest the fighting strength of the state be impaired. We mention these extreme cases because the contention is extreme. We do not believe in the soundness of the views which uphold this law. On the contrary, we think that such a law as this, although passed in the assumed exercise of the police power, and as relating to the public health, or the health of the employees named, is not within that power, and is invalid. The act is not, within any fair meaning of the term, a health law, but is an illegal interference with the rights of individuals, both employers and employees, to make contracts regarding labor upon such terms as they may think best, or which they may agree upon with the other parties to such contracts. Statutes of the nature of that under review, limiting the hours in which grown and intelligent men may labor to earn their living, are mere meddlesome interferences with the rights of the individual, and they are not saved from condemnation by the claim that they are passed in the exercise of the police power and upon the subject of the health of the individual whose rights are interfered with, unless there be some fair ground, reasonable in and of itself, to say that there is material danger to the public health, or to the health of the employees, if the hours of labor are not curtailed. If this be not clearly the case, the individuals whose rights are thus made the subject of legislative interference are under the protection of the Federal Constitution regarding their liberty of contract as well as of person; and the legislature of the state has no power to limit their right as proposed in this statute. All that it could properly do has been done by it with regard to the conduct of bakeries, as provided for in the other sections of the act, above set forth. These several sections provide for the inspection of the premises where the bakery is carried on, with regard to furnishing proper wash rooms and waterclosets, apart from the bake room, also with regard to providing proper drainage, plumbing, and painting; the sections, in addition, provide for the height of the ceiling, the cementing or tiling of floors, where necessary in the opinion of the factory inspector, and for other things of that nature; alterations are also provided for, and are to be made where necessary in the opinion of the inspector, in order to comply with the provisions of the statute. These various sections may be wise and valid regulations, and they certainly go to the full extent of providing for the cleanliness and the healthiness, so far as possible, of the quarters in which bakeries are to be conducted. Adding to all these requirements a prohibition to enter into any contract of labor in a bakery for more than a certain number of hours a week is, in our judgment, so wholly beside the matter of a proper, reasonable, and fair provision as to run counter to that liberty of person and of free contract provided for in the Federal Constitution.

It was further urged on the argument that restricting the hours of labor in the case of bakers was valid because it tended to cleanliness on the part of the workers, as a man was more apt to be cleanly when not overworked, and if cleanly then his “output” was also more likely to be so. What has already been said applies with equal force to this contention. We do not admit the reasoning to be sufficient to justify the claimed right of such interference. The state in that case would assume the position of a supervisor, or pater familias, over every act of the individual, and its right of governmental interference with his hours of labor, his hours of exercise, the character thereof, and the extent to which it shall be carried would be recognized and upheld. In our judgment it is not possible in fact to discover the connection between the number of hours a baker may work in the bakery and the healthful quality of the bread made by the workman. The connection, if any exist, is too shadowy and thin to build any argument for the interference of the legislature. If the man works ten hours a day it is all right, but if ten and a half or eleven his health is in danger and his bread may be unhealthy, and, therefore, he shall not be permitted to do it. This, we think, is unreasonable and entirely arbitrary. When assertions such as we have adverted to become necessary in order to give, if possible, a plausible foundation for the contention that the law is a “health law,” it gives rise to at least a suspicion that there was some other motive dominating the legislature than the purpose to subserve the public health or welfare.

. . .

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.

REVERSED.

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. . . . 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.”. . .

The authorities on the same line are so numerous that further citations are unnecessary.

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 . . . )   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. . . . If there be doubt as to the validity of the statute, that doubt must therefore be resolved in favor of its validity, and the courts must keep their hands off, leaving the legislature to meet the responsibility for unwise legislation. If the end which the legislature seeks to accomplish be one to which its power extends, and if the means employed to that end, although not the wisest or best, are yet not plainly and palpably unauthorized by law, then the court cannot interfere. In other words, when the validity of a statute is questioned, the burden of proof, so to speak, is upon those who assert it to be unconstitutional. (McCulloch v. Maryland . . . )

Let these principles be applied to the present case. . . .

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) 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); or that it is not promotive of the health of the employees in question ( Holden v. Hardy; Lawton v. Steele); or that the regulation prescribed by the state is utterly unreasonable and extravagant or wholly arbitrary (Gundling v. Chicago). 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) 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.

. . .

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. . . . 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. . . .

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.

If such reasons exist that ought to be the end of this case, for the state is not amenable to the judiciary, in respect of its legislative enactments, unless such enactments are plainly, palpably, beyond all question, inconsistent with the Constitution of the United States. We are not to presume that the state of New York has acted in bad faith. Nor can we assume that its legislature acted without due deliberation, or that it did not determine this question upon the fullest attainable information and for the common good. We cannot say that the state has acted without reason, nor ought we to proceed upon the theory that its action is a mere sham. Our duty, I submit, is to sustain the statute as not being in conflict with the Federal Constitution, for the reason―and such is an all-sufficient reason―it is not shown to be plainly and palpably inconsistent with that instrument. Let the state alone in the management of its purely domestic affairs, so long as it does not appear beyond all question that it has violated the Federal Constitution. This view necessarily results from the principle that the health and safety of the people of a state are primarily for the state to guard and protect.

I take leave to say that the New York statute, in the particulars here involved, cannot be held to be in conflict with the 14th Amendment, without enlarging the scope of the amendment far beyond its original purpose, and without bringing under the supervision of this court matters which have been supposed to belong exclusively to the legislative departments of the several states when exerting their conceded power to guard the health and safety of their citizens by such regulations as they in their wisdom deem best. Health laws of every description constitute, said Chief Justice Marshall, a part of that mass of legislation which “embraces everything within the territory of a state, not surrendered to the general government; all which can be most advantageously exercised by the states themselves.” (Gibbons v. Ogden) A decision that the New York statute is void under the 14th Amendment will, in my opinion, involve consequences of a far-reaching and mischievous character; for such a decision would seriously cripple the inherent power of the states to care for the lives, health, and wellbeing of their citizens. Those are matters which can be best controlled by the states. The preservation of the just powers of the states is quite as vital as the preservation of the powers of the general government.

When this court had before it the question of the constitutionality of a statute of Kansas making it a criminal offense for a contractor for public work to permit or require his employees to perform labor upon such work in excess of eight hours each day, it was contended that the statute was in derogation of the liberty both of employees and employer. It was further contended that the Kansas statute was mischievous in its tendencies. This court, while disposing of the question only as it affected public work, held that the Kansas statute was not void under the 14th Amendment. But it took occasion to say what may well be here repeated: “The responsibility therefor rests upon legislators, not upon the courts. No evils arising from such legislation could be more far reaching than those that might come to our system of government if the judiciary, abandoning the sphere assigned to it by the fundamental law, should enter the domain of legislation, and upon grounds merely of justice or reason or wisdom annul statutes that had received the sanction of the people’s representatives. 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)

The judgment, in my opinion, should be affirmed.

Mr. Justice Holmes dissenting:

I regret sincerely that I am unable to agree with the judgment 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 Post Office, 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) 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) 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) The decision sustaining an eight-hour law for miners is still recent. (Holden v. Hardy) 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.
