The Legislature of New York established by chapter 158 of the Laws of 1933, a Milk Control Board with power, among other things to 'fix minimum and maximum * * * retail prices to be charged by * * * stores to consumers for consumption off the premises where sold.' Agriculture and Markets Law N.Y. (Consol. Laws, c. 69) § 312. The board fixed nine cents as the price to be charged by a store for a quart of milk. Nebbia, the proprietor of a grocery store in Rochester, sold two quarts and a 5-cent loaf of bread for 18 cents; and was convicted for violating the board's order. At his trial he asserted the statute and order contravene the equal protection clause and the due process clause of the Fourteenth Amendment, and renewed the contention in successive appeals to the county court and Court of Appeals. Both overruled his claim and affirmed the conviction.1

The question for decision is whether the Federal Constitution prohibits a state from so fixing the selling price of milk. We first inquire as to the occasion for the legislation and its history.

During 1932 the prices received by farmers for milk were much below the cost of production. The decline in prices during 1931 and 1932 was much greater than that of prices generally. The situation of the families of dairy producers had become desperate and called for state aid similar to that afforded the unemployed, if conditions should not improve.

On March 10, 1932, the senate and assembly resolved, 'That a joint Legislative committee is hereby created * * * to investigate the causes of the decline of the price of milk to producers and the resultant effect of the low prices upon the dairy industry and the future supply of milk to the cities of the State; to investigate the cost of distribution of milk and its relation to prices paid to milk producers, to the end that the consumer may be assured of an adequate supply of milk at a reasonable price, both to producer and consumer.' The committee organized May 6, 1932, and its activities lasted nearly a year. It held 13 public hearings at which 254 witnesses testified and 2,350 typewritten pages of testimony were taken. Numerous exhibits were submitted. Under its direction an extensive research program was prosecuted by experts and official bodies and employees of the state and municipalities, which resulted in the assembling of much pertinent information. Detailed reports were received from over 100 distributors of milk, and these were collated and the information obtained analyzed. As a result of the study of this material a report covering 473 closely printed pages, embracing the conclusions and recommendations of the committee, was presented to the Legislature April 10, 1933. This document included detailed findings with copious references to the supporting evidence; appendices outlining the nature and results of prior investigations of the milk industry of the state, briefs upon the legal questions involved, and forms of bills recommended for passage. The conscientious effort and thoroughness exhibited by the report lend weight to the committee's conclusions.

Milk is an essential item of diet. It cannot long be stored. It is an excellent medium for growth of bacteria. These facts necessitate safeguards in its production and handling for human consumption which greatly increase the cost of the business. Failure of producers to receive a reasonable return for their labor and investment over an extended period threaten a relaxation of vigilance against contamination.

The production and distribution of milk is a paramount industry of the state, and largely affects the health and prosperity of its people. Dairying yields fully one-half of the total income from all farm products. Dairy farm investment amounts to approximately $1,000,000,000. Curtailment or destruction of the dairy industry would cause a serious economic loss to the people of the state.

In addition to the general price decline, other causes for the low price of milk include a periodic increase in the number of cows and in milk production, the prevalence of unfair and destructive trade practices in the distribution of milk, leading to a demoralization of prices in the metropolitan area and other markets, and the failure of transportation and distribution charges to be reduced in proportion to the reduction in retail prices for milk and cream.

The fluid milk industry is affected by factors of instability peculiar to itself which call for special methods of control. Under the best practicable adjustment of supply to demand the industry must carry a surplus of about 20 per cent., because milk, an essential food, must be available as demanded by consumers every day in the year, and demand and supply vary from day to day and according to the reason; but milk is perishable and cannot be stored. Close adjustment of supply to demand is hindered by several factors difficult to control. Thus surplus milk presents a serious problem, as the prices which can be realized for it for other uses are much less than those obtainable for milk sold for consumption in fluid form or as cream. A satisfactory stabilization of prices for fluid milk requires that the burden of surplus milk be shared equally by all producers and all distributors in the milk shed. So long as the surplus burden is unequally distributed the pressure to market surplus milk in fluid form will be a serious disturbing factor. The fact that the larger distributors find it necessary to carry large quantities of surplus milk, while the smaller distributors do not, leads to price-cutting and other forms of destructive competition. Smaller distributors, who take no responsibility for the surplus, by purchasing their milk at the blended prices (i.e., an average between the price paid the producer for milk for sale as fluid milk, and the lower surplus milk price paid by the larger organizations) can undersell the larger distributors. Indulgence in this price-cutting often compels the larger dealer to cut the price to his own and the producer's detriment.

Various remedies were suggested, amongst them united action by producers, the fixing of minimum prices for milk and cream by state authority, and the imposition of certain graded taxes on milk dealers proportioned so as to equalize the cost of milk and cream to all dealers and so remove the cause of price-cutting.

The Legislature adopted chapter 158 as a method of correcting the evils, which the report of the committee showed could not be expected to right themselves through the ordinary play of the forces of supply and demand, owing to the peculiar and uncontrollable factors affecting the industry. The provisions of the statute are summarized in the margin.2

Section 312(e) on which the prosecution in the present case is founded, provides: 'After the board shall have fixed prices to be charged or paid for milk in any form * * * it shall be unlawful for a milk dealer to sell or buy or offer to sell or buy milk at any price less or more than such price, * * * and no method or device shall be lawful whereby milk is bought or sold * * * at a price less or more than such price * * * whether by any discount, or rebate, or free service, or advertising allowance, or a combined price for such milk together with another commodity or commodities, or service or services, which is less or more than the aggregate of the prices for the milk and the price or prices for such other commodity or commodities, or service or services, when sold or offered for sale separately or otherwise. * * *'

First. The appellant urges that the order of the Milk Control Board denies him the equal protection of the laws. It is shown that the order requires him, if he purchases his supply from a dealer, to pay 8 cents per quart and 5 cents per pint, and to resell at not less than 9 and 6, whereas the same dealer may buy his supply from a farmer at lower prices and deliver milk to consumers at 10 cents the quart and 6 cents the pint. We think the contention that the discrimination deprives the appellant of equal protection is not well founded. For aught that appears, the appellant purchased his supply of milk from a farmer as do distributors, or could have procured it from a farmer if he so desired. There is therefore no showing that the order placed him at a disadvantage, or in fact affected him adversely, and this alone is fatal to the claim of denial of equal protection. But if it were shown that the appellant is compelled to buy from a distributor, the difference in the retail price he is required to charge his customers, from that prescribed for sales by distributors is not on its face arbitrary or unreasonable, for there are obvious distinctions between the two sorts of merchants which may well justify a difference of treatment, if the Legislature possesses the power to control the prices to be charged for fluid milk. Compare American Sugar Refining Co. v. Louisiana, 179 U.S. 89, 21 S.Ct. 43, 45 L.Ed. 102; Brown-Forman Co. v. Kentucky, 217 U.S. 563, 30 S.Ct. 578, 54 L.Ed. 883; State Board of Tax Commissioners v. Jackson, 283 U.S. 527, 51 S.Ct. 540, 75 L.Ed. 1248, 73 A.L.R. 1464.

Second. The more serious question is whether, in the light of the conditions disclosed, the enforcement of section 312(e) denied the appellant the due process secured to him by the Fourteenth Amendment.

Save the conduct of railroads, no business has been so thoroughly regimented and regulated by the State of New York as the milk industry. Legislation controlling it in the interest of the public health was adopted in 18623 and subsequent statutes,4 have been carried into the general codification known as the Agriculture and Markets Law.5 A perusal of these statutes discloses that the milk industry has been progressively subjected to a larger measure of control.6 The producer or dairy farmer is in certain circumstances liable to have his herd quarantined against bovine tuberculosis; is limited in the importation of dairy cattle to those free from Bang's disease; is subject to rules governing the care and feeding of his cows and the care of the milk produced, the condition and surroundings of his barns and buildings used for production of milk, the utensils used, and the persons employed in milking (sections 46, 47, 55, 72—88). Proprietors of milk gathering stations or processing plants are subject to regulation (section 54), and persons in charge must operate under license and give bond to comply with the law and regulations; must keep records, pay promptly for milk purchased, abstain from false or misleading statements and from combinations to fix prices (sections 57, 57-a, 252). In addition there is a large volume of legislation intended to promote cleanliness and fair trade practices, affecting all who are engaged in the industry.7 The challenged amendment of 1933 carried regulation much farther than the prior enactments. Appellant insists that it went beyond the limits fixed by the Constitution.

Under our form of government the use of property and the making of contracts are normally matters of private and not of public concern. The general rule is that both shall be free of governmental interference. But neither property rights8 nor contract rights9 are absolute; for government cannot exist if the citizen may at will use his property to the detriment of his fellows, or exercise his freedom of contract to work them harm. Equally fundamental with the private right is that of the public to regulate it in the common interest. As Chief Justice Marshall said, speaking specifically of inspection laws, such laws form 'a portion of that immense mass of legislation which embraces everything within the territory of a state, * * * all which can be most advantageously exercised by the states themselves. Inspection laws, quarantine laws, health laws of every description, as well as laws for regulating the internal commerce of a state, * * * are component parts of this mass.'10

Justice Barbour said for this court: '* * * 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 conductive 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.'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 offenses, 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 power; 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

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,13 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.

The Fifth Amendment, in the field of federal activity,14 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.16 The state may control the use of property in various ways; may prohibit advertising bill boards except of a prescribed size and location,17 or their use for certain kinds of advertising;18 may in certain circumstances authorize encroachments by party walls in cities;19 may fix the height of buildings, the character of materials, and methods of construction, the adjoining area which must be left open, and may exclude from residential sections offensive trades, industries and structures likely injuriously to affect the public health or safety;20 or may establish zones within which certain types of buildings or businesses are permitted and others excluded.21 And although the Fourteenth Amendment extends protection to aliens as well as citizens,22 a state may for adequate reasons of policy exclude aliens altogether from the use and occupancy of land.23

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.24 These measures not only affected the use of private property, but also interfered with the right of private contract. Other instances are numerous where valid regulation has restricted the right of contract, while less directly affecting property rights.25

The Constitution does not guarantee the unrestricted privilege to engage in a business or to conduct it as one pleases. Certain kinds of business may be prohibited;26 and the right to conduct a business, or to pursue a calling, may be conditioned.27 Regulation of a business to prevent waste of the state's resources may be justified.28 And statutes prescribing the terms upon which those conducting certain businesses may contract, or imposing terms if they do enter into agreements, are within the state's competency.29

Legislation concerning sales of goods, and incidentally affecting prices, has repeatedly been held valid. In this class fall laws forbidding unfair competition by the charging of lower prices in one locality than those exacted in another,30 by giving trade inducements to purchasers,31 and by other forms of price discrimination.32 The public policy with respect to free competition has engendered state and federal statutes prohibiting monopolies,33 which have been upheld. On the other hand, where the policy of the state dictated that a monopoly should be granted, statutes having that effect have been held inoffensive to the constitutional guarantees.34 Moreover, the state or a municipality may itself enter into business in competition with private proprietors, and thus effectively although indirectly control the prices charged by them.35

The milk industry in New York has been the subject of long-standing and drastic regulation in the public interest. The legislative investigation of 1932 was persuasive of the fact that for this and other reasons unrestricted competition aggravated existing evils and the normal law of supply and demand was insufficient to correct maladjustments detrimental to the community. The inquiry disclosed destructive and demoralizing competitive conditions and unfair trade practices which resulted in retail price cutting and reduced the income of the farmer below the cost of production. We do not understand the appellant to deny that in these circumstances the Legislature might reasonably consider further regulation and control desirable for protection of the industry and the consuming public. That body believed conditions could be improved by preventing destructive price-cutting by stores which, due to the flood of surplus milk, were able to buy at much lower prices than the larger distributors and to sell without incurring the delivery costs of the latter. In the order of which complaint is made the Milk Control Board fixed a price of 10 cents per quart for sales by a distributor to a consumer, and 9 cents by a store to a consumer, thus recognizing the lower costs of the store, and endeavoring to establish a differential which would be just to both. In the light of the facts the order appears not to be unreasonable or arbitrary, or without relation to the purpose to prevent ruthless competition from destroying the wholesale price structure on which the farmer depends for his livelihood, and the community for an assured supply of milk.

But we are told that because the law essays to control prices it denies due process. Notwithstanding the admitted power to correct existing economic ills by appropriate regulation of business, even though an indirect result may be a restriction of the freedom of contract or a modification of charges for services or the price of commodities, the appellant urges that direct fixation of prices is a type of regulation absolutely forbidden. His position is that the Fourteenth Amendment requires us to hold the challenged statute void for this reason alone. The argument runs that the public control of rates or prices is per se unreasonable and unconstitutional, save as applied to businesses affected with a public interest; that a business so affected is one in which property is devoted to an enterprise of a sort which the public itself might appropriately undertake, or one whose owner relies on a public grant or franchise for the right to conduct the business, or in which he is bound to serve all who apply; in short, such as is commonly called a public utility; or a business in its nature a monopoly. The milk industry, it is said, possesses none of these characteristics, and, therefore, not being affected with a public interest, its charges may not be controlled by the state. Upon the soundness of this contention the appellant's case against the statute depends.

We may as well say at once that the dairy industry is not, in the accepted sense of the phrase, a public utility. We think the appellant is also right in asserting that there is in this case no suggestion of any monopoly or monopolistic practice. It goes without saying that those engaged in the business are in no way dependent upon public grants or franchises for the privilege of conducting their activities. But if, as must be conceded, the industry is subject to regulation in the public interest, what constitutional principle bars the state from correcting existing maladjustments by legislation touching prices? We think there is no such principle. The due process clause makes no mention of sales or of prices any more than it speaks of business or contracts or buildings or other incidents of property. The thought seems nevertheless to have persisted that there is something peculiarly sacrosanct about the price one may charge for what he makes or sells, and that, however able to regulate other elements of manufacture or trade, with incidental effect upon price, the state is incapable of directly controlling the price itself. This view was negatived many years ago. Munn v. Illinois, 94 U.S. 113, 24 L.Ed. 77. The appellant's claim is, however, that this court, in there sustaining a statutory prescription of charges for storage by the proprietors of a grain elevator, limited permissible legislation of that type to businesses affected with a public interest, and he says no business is so affected except it have one or more of the characteristics he enumerates. But this is a misconception. Munn and Scott held no franchise from the state. They owned the property upon which their elevator was situated and conducted their business as private citizens. No doubt they felt at liberty to deal with whom they pleased and on such terms as they might deem just to themselves. Their enterprise could not fairly be called a monopoly, although it was referred to in the decision as a 'virtual monopoly.' This meant only that their elevator was strategically situated and that a large portion of the public found it highly inconvenient to deal with others. This court concluded the circumstances justified the legislation as an exercise of the governmental right to control the business in the public interest; that is, as an exercise of the police power. It is true that the court cited a statement from Lord Hale's De Portibus Maris, to the effect that when private property is 'affected with a public interest, it ceases to be juris privati only'; but the court proceeded at once to define what it understood by the expression, saying: 'Property does become clothed with a public interest when used in a manner to make it of public consequence, and affect the community at large.' Page 126 of 94 U.S. Thus understood, 'affected with a public interest' is the equivalent of 'subject to the exercise of the police power'; and it is plain that nothing more was intended by the expression. The court had been at pains to define that power (pages 124, 125 of 94 U.S.) ending its discussion in these words: 'From this it is apparent that, down to the time of the adoption of the Fourteenth Amendment, it was not supposed that statutes regulating the use, or even the price of the use, of private property necessarily deprived an owner of his property without due process of law. Under some circumstances they may, but not under all. The amendment does not change the law in this particular; it simply prevents the States from doing that which will operate as such a deprivation.'36

In the further discussion of the principle it is said that when one devotes his property to a use, 'in which the public has an interest,' he in effect 'grants to the public an interest in that use' and must submit to be controlled for the common good. The conclusion is that if Munn and Scott wished to avoid having their business regulated they should not have embarked their property in an industry which is subject to regulation in the public interest.

The true interpretation of the court's language is claimed to be that only property voluntarily devoted to a known public use is subject to regulation as to rates. But obviously Munn and Scott had not voluntarily dedicated their business to a public use. They intended only to conduct it as private citizens, and they insisted that they had done nothing which gave the public an interest in their transactions or conferred any right of regulation. The statement that one has dedicated his property to a public use is, therefore, merely another way of saying that if one embarks in a business which public interest demands shall be regulated, he must know regulation will ensue.

In the same volume the court sustained regulation of railroad rates.37 After referring to the fact that railroads are carriers for hire, are incorporated as such, and given extraordinary powers in order that they may better serve the public, it was said that they are engaged in employment 'affecting the public interest,' and therefore, under the doctrine of the Munn Case, subject to legislative control as to rates. And in another of the group of railroad cases then heard38 it was said that the property of railroads is 'clothed with a public interest' which permits legislative limitation of the charges for its use. Plainly the activities of railroads, their charges and practices, so nearly touch the vital economic interests of society that the police power may be invoked to regulate their charges, and no additional formula of affectation or clothing with a public interest is needed to justify the regulation. And this is evidently true of all business units supplying transportation, light, heat, power and water to communities, irrespective of how they obtain their powers.

The touchstone of public interest in any business, its practices and charges, clearly is not the enjoyment of any franchise from the state, Munn v. Illinois, supra. Nor is it the enjoyment of a monopoly; for in Brass v. North Dakota, 153 U.S. 391, 14 S.Ct. 857, 38 L.Ed. 757, a similar control of prices of grain elevators was upheld in spite of overwhelming and uncontradicted proof that about six hundred grain elevators existed along the line of the Great Northern Railroad, in North Dakota; that at the very station where the defendant's elevator was located two others operated; and that the business was keenly competitive throughout the state.

In German Alliance Insurance Co. v. Lewis, 233 U.S. 389, 34 S.Ct. 612, 58 L.Ed. 1011, L.R.A. 1915C, 1189, a statute fixing the amount of premiums for fire insurance was held not to deny due process. Though the business of the insurers depended on no franchise or grant from the state, and there was no threat of monopoly, two factors rendered the regulation reasonable. These were the almost universal need of insurance protection and the fact that while the insurers competed for the business, they all fixed their premiums for similar risks according to an agreed schedule of rates. The court was at pains to point out that it was impossible to lay down any sweeping and general classification of businesses as to which price-regulation could be adjudged arbitrary or the reverse.

Many other decisions show that the private character of a business does not necessarily remove it from the realm of regulation of charges or prices. The usury laws fix the price which may be exacted for the use of money, although no business more essentially private in character can be imagined than that of loaning one's personal funds. Griffith v. Connecticut, 218 U.S. 563, 31 S.Ct. 132, 54 L.Ed. 1151. Insurance agents' compensation may be regulated, though their contracts are private, because the business of insurance is considered one properly subject to public control. O'Gorman & Young v. Hartford Ins. Co., 282 U.S. 251, 51 S.Ct. 130, 75 L.Ed. 324, 72 A.L.R. 1163. Statutes prescribing in the public interest the amounts to be charged by attorneys for prosecuting certain claims, a matter ordinarily one of personal and private nature, are not a deprivation of due process. Frisbie v. United States, 157 U.S. 160, 15 S.Ct. 586, 39 L.Ed. 657; Capital Trust Co. v. Calhoun, 250 U.S. 208, 39 S.Ct. 486, 63 L.Ed. 942; Calhoun v. Massie, 253 U.S. 170, 40 S.Ct. 474, 64 L.Ed. 843; Newman v. Moyers, 253 U.S. 182, 40 S.Ct. 478, 64 L.Ed. 849; Yeiser v. Dysart, 267 U.S. 540, 45 S.Ct. 399, 69 L.Ed. 775; Margolin v. United States, 269 U.S. 93, 46 S.Ct. 64, 70 L.Ed. 176. A stockyards corporation, 'while not a common carrier, nor engaged in any distinctively public employment, is doing a work in which the public has an interest,' and its charges may be controlled. Cotting v. Kansas City Stock Yards Co., 183 U.S. 79, 85, 22 S.Ct. 30, 46 L.Ed. 92. Private contract carriers, who do not operate under a franchise, and have no monopoly of the carriage of goods or passengers, may, since they use the highways to compete with railroads, be compelled to charge rates not lower than those of public carriers for corresponding services, if the state, in pursuance of a public policy to protect the latter, so determines. Stephenson v. Binford, 287 U.S. 251, 274, 53 S.Ct. 181, 77 L.Ed. 288, 87 A.L.R. 721.

It is clear that there is no closed class or category of businesses affected with a public interest, and the function of courts in the application of the Fifth and Fourteenth Amendments is to determine in each case whether circumstances vindicate the challenged regulation as a reasonable exertion of governmental authority or condemn it as arbitrary or discriminatory. Wolff Packing Co. v. Court of Industrial Relations, 262 U.S. 522, 535, 43 S.Ct. 630, 67 L.Ed. 1103, 27 A.L.R. 1280. The phrase 'affected with a public interest' can, in the nature of things, mean no more than that an industry, for adequate reason, is subject to control for the public good. In several of the decisions of this court wherein the expressions 'affected with a public interest,' and 'clothed with a public use,' have been brought forward as the criteria of the validity of price control, it has been admitted that they are not susceptible of definition and form an unsatisfactory test of the constitutionality of legislation directed at business practices or prices. These decisions must rest, finally, upon the basis that the requirements of due process were not met because the laws were found arbitrary in their operation and effect.39 But there can be no doubt that upon proper occasion and by appropriate measures the state may regulate a business in any of its aspects, including the prices to be charged for the products or commodities it sells.

So far as the requirement of due process is concerned, and in the absence of other constitutional restriction, a state is free to adopt whatever economic policy may reasonably be deemed to promote public welfare, and to enforce that policy by legislation adapted to its purpose. The courts are without authority either to declare such policy, or, when it is declared by the legislature, to override it. If the laws passed are seen to have a reasonable relation to a proper legislative purpose, and are neither arbitrary nor discriminatory, the requirements of due process are satisfied, and judicial determination to that effect renders a court functus officio. 'Whether the free operation of the normal laws of competition is a wise and wholesome rule for trade and commerce is an economic question which this court need not consider or determine.' Northern Securities Co. v. United States, 193 U.S. 197, 337, 338, 24 S.Ct. 436, 457, 48 L.Ed. 679. And it is equally clear that if the legislative policy be to curb unrestrained and harmful competition by measures which are not arbitrary or discriminatory it does not lie with the courts to determine that the rule is unwise. With the wisdom of the policy adopted, with the adequacy or practicability of the law enacted to forward it, the courts are both incompetent and unauthorized to deal. The course of decision in this court exhibits a firm adherence to these principles. Times without number we have said that the Legislature is primarily the judge of the necessity of such an enactment, that every possible presumption is in favor of its validity, and that though the court may hold views inconsistent with the wisdom of the law, it may not be annulled unless palpably in excess of legislative power.40

The lawmaking bodies have in the past endeavored to promote free competition by laws aimed at trusts and monopolies. The consequent interference with private property and freedom of contract has not availed with the courts to set these enactments aside as denying due process.41 Where the public interest was deemed to require the fixing of minimum prices, that expedient has been sustained.42 If the lawmaking body within its sphere of government concludes that the conditions or practices in an industry make unrestricted competition an inadequate safeguard of the consumer's interests,43 produce waste harmful to the public, threaten ultimately to cut off the supply of a commodity needed by the public, or portend the destruction of the industry itself, appropriate statutes passed in an honest effort to correct the threatened consequences may not be set aside because the regulation adopted fixes prices reasonably deemed by the Legislature to be fair to those engaged in the industry and to the consuming public. And this is especially so where, as here, the economic maladjustment is one of price, which threatens harm to the producer at one end of the series and the consumer at the other. The Constitution does not secure to any one liberty to conduct his business in such fashion as to inflict injury upon the public at large, or upon any substantial group of the people. Price control, like any other form of regulation, is unconstitutional only if arbitrary, discriminatory, or demonstrably irrelevant to the policy the Legislature is free to adopt, and hence an unnecessary and unwarranted interference with individual liberty.

Tested by these considerations we find no basis in the due process clause of the Fourteenth Amendment for condemning the provisions of the Agriculture and Markets Law here drawn into question.

The judgment is affirmed.

Separate opinion of Mr. Justice McREYNOLDS.

By an act effective April 10, 1933 (Laws 1933, ch. 158), when production of milk greatly exceeded the demand, the Legislature created a Control Board with power to 'regulate the entire milk industry of New York state, including the production, transportation, manufacture, storage, distribution, delivery and sale. * * *' Agriculture and Markets Law N.Y. § 303. The 'board may adopt and enforce all rules and all orders necessary to carry out the provisions of this article. * * * A rule of the board when duly posted and filed as provided in this section shall have the force and effect of law. * * * A violation of any provision of this article or of any rule or order of the board lawfully made, except as otherwise expressly provided by this article, shall be a misdemeanor. * * *' Sections 304, 307. After considering 'all conditions affecting the milk industry including the amount necessary to yield a reasonable return to the producer and to the milk dealer * * *' the board 'shall fix by official order the minimum wholesale and retail prices and may fix by official order the maximum wholesale and retail prices to be charged for milk handled within the state.' Section 312.

April 17, this board prescribed 9 cents per quart as the minimum at which 'a store' might sell.* April 19, appellant Nebbia, a small storekeeper in Rochester, sold two bottles at a less price. An information charged that by so doing he committed a misdemeanor. A motion to dismiss which challenged the validity of both statute and order being overruled, the trial proceeded under a plea of not guilty. The board's order and statements by two witnesses tending to show the alleged sale constituted the entire evidence. Notwithstanding the claim, that under the Fourteenth Amendment the state lacked power to prescribe prices at which he might sell pure milk, lawfully held, he was adjudged guilty and ordered to pay a fine.

The Court of Appeals (262 N.Y. 259, 186 N.E. 694, 695) affirmed the conviction. Among other things, it said:

The sale by Nebbia was a violation of the statute 'inasmuch as the Milk Control Board had fixed a minimum price for milk of 9 cents per quart. * * *

'The appellant not unfairly summarizes this law by saying that it first declares that milk has been selling too cheaply in the state of New York, and has thus created a temporary emergency; this emergency is remedied by making the sale of milk at a low price a crime; the question of what is a low price is determined by the majority vote of three officials. As an aid in enforcing the rate regulation, the milk industry in the state of New York is made a business affecting the public health and interest until March 31, 1934, and the board can exclude from the milk business any violator of the statute or the board's orders.'

In fixing (sale) prices the board 'must take into consideration the amount necessary to yield a 'reasonable return' to the producer and the milk dealer. * * * The fixing of minimum prices is one of the main features of the act. The question is whether the act, so far as it provides for fixing minimum prices for milk, is unconstitutional * * * in that it interferes with the right of the milk dealer to carry on his business in such manner as suits his convenience, without state interference as to the price at which he shall sell his milk. The power thus to regulate private business can be invoked only under special circumstances. It may be so invoked when the Legislature is dealing with a paramount industry upon which the prosperity of the entire state in large measure depends. It may not be invoked when we are dealing with an ordinary business, essentially private in its nature. This is the vital distinction pointed out in New State Ice Co. v. Liebmann, 285 U.S. 262, 277, 52 S.Ct. 371, 76 L.Ed. 747. * * *

'The question is as to whether the business justifies the particular restriction, or whether the nature of the business is such that any competent person may, conformably to reasonable regulation, engage therein. The production of milk is, on account of its great importance as human food, a chief industry of the state of New York. * * * It is of such paramount importance as to justify the assertion that the general welfare and prosperity of the state in a very large and real sense depend upon it. * * * The state seeks to protect the producer by fixing a minimum price for his milk to keep open the stream of milk flowing from the farm to the city and to guard the farmer from substantial loss. * * * Price is regulated to protect the farmer from the exactions of purchasers against which he cannot protect himself. * * *

'Concededly the Legislature cannot decide the question of emergency and regulation, free from judicial review, but this court should consider only the legitimacy of the conclusions drawn from the facts found.

'We are accustomed to rate regulation in cases of public utilities and other analogous cases and to the extension of such regulative power into similar fields. * * * This case, for example, may be distinguished from the Oklahoma Ice Case (New State Ice Co. v. Liebmann, supra (285 U.S. 262, 277, 52 S.Ct. 371, 76 L.Ed. 747)), holding that the business of manufacturing and selling ice cannot be made a public business, to which it bears a general resemblance. The New York law creates no monopoly; does not restrict production; was adopted to meet an emergency; milk is a greater family necessity than ice. * * * Mechanical concepts of jurisprudence make easy a decision on the strength of seeming authority. * * *

'Doubtless the statute before us would be condemned by an earlier generation as a temerarious interference with the rights of property and contract * * *; with the natural law of supply and demand. But we must not fail to consider that the police power is the least limitable of the powers of government and that it extends to all the great public needs; * * * that statutes aiming to * * * stimulate the production of a vital food product by fixing living standards of prices for the producer, are to be interpreted with that degree of liberality which is essential to the attainment of the end in view. * * *

'With full respect for the Constitution as an efficient frame of government in peace and war, under normal conditions or in emergencies, with cheerful submission to the rule of the Supreme Court that legislative authority to abridge property rights and freedom of contract can be justified only by exceptional circumstances and, even then, by reasonable regulation only, and that legislative conclusions based on findings of fact are subject to judicial review, we do not feel compelled to hold that the 'due process' clause of the Constitution has left milk producers unprotected from oppression and to place the stamp of invalidity on the measure before us.

'With the wisdom of the legislation we have naught to do. It may be vain to hope by laws to oppose the general course of trade. * * *

'We are unable to say that the Legislature is lacking in power, not only to regulate and encourage the production of milk, but also, when conditions require, to regulate the prices to be paid for it, so that a fair return may be obtained by the producer and a vital industry preserved from destruction. * * * The policy of noninterference with individual freedom must at times give way to the policy of compulsion for the general welfare.'

Our question is whether the control act, as applied to appellant through the order of the board, No. 5, deprives him of rights guaranteed by the Fourteenth Amendment. He was convicted of a crime for selling his own property—wholesome milk—in the ordinary course of business at a price satisfactory to himself and the customer. We are not immediately concerned with any other provision of the act or later orders. Prices at which the producer may sell were not prescribed he may accept any price—nor was production in any way limited. 'To stimulate the production of a vital food product' was not the purpose of the statute. There was an oversupply of an excellent article. The affirmation is 'that milk has been selling too cheaply * * * and has thus created a temporary emergency; this emergency is remedied by making the sale of milk at a low price a crime.'

The opinion below points out that the statute expires March 31, 1934, 'and is avowedly a mere temporary measure to meet an existing emergency'; but the basis of the decision is not explicit. There was no definite finding of an emergency by the court upon consideration of established facts and no pronouncement that conditions were accurately reported by a legislative committee. Was the legislation upheld because only temporary and for an emergency; or was it sustained upon the view that the milk business bears a peculiar relation to the public, is affected with a public interest, and, therefore, sales prices may be prescribed irrespective of exceptional circumstances? We are left in uncertainty. The two notions are distinct if not conflicting. Widely different results may follow adherence to one or the other.

The theory that legislative action which ordinarily would be ineffective because of conflict with the Constitution may become potent if intended to meet peculiar conditions and properly limited, was lucidly discussed and its weakness disclosed by the dissenting opinion in Home Building & Loan Ass'n v. Blaisdell, 290 U.S. 398, 54 S.Ct. 231, 78 L.Ed. 413 (January 8, 1934). Sixty years ago, in Milligan's Case, 4 Wall. 2, 18 L.Ed. 281, this Court declared it inimicable to constitutional government and did 'write the vision and make it plain upon tables that he may run that readeth it.'

Milligan, charged with offenses against the United States committed during 1863 and 1864, was tried, convicted, and sentenced to be hanged by a military commission proceeding under an act of Congress passed in 1862. The crisis then existing was urged in justification of its action. But this Court held the right of trial by jury did not yield to emergency; and directed his release. 'Those great and good men (who drafted the Constitution) foresaw that troublous times would arise, when rulers and people would become restive under restraint, and seek by sharp and decisive measures to accomplish ends deemed just and proper; and that the principles of constitutional liberty would be in peril, unless established by irrepealable law. * * * The Constitution of the United States is a law for rulers and people, equally in war and in peace, and covers with the shield of its protection all classes of men, at all times, and under all circumstances. No doctrine, involving more pernicious consequences, was ever invented by the wit of man than that any of its provisions can be suspended during any of the great exigencies of government. Such a doctrine leads directly to anarchy or despotism.' Ex parte Milligan (1866) 4 Wall. 2, 120, 18 L.Ed. 281.

The Fourteenth Amendment wholly disempowered the several states to 'deprive any person of life, liberty, or property, without due process of law.' The assurance of each of these things is the same. If now liberty or property may be struck down because of difficult circumstances, we must expect that hereafter every right must yield to the voice of an impatient majority when stirred by distressful exigency. Amid the turmoil of civil war Milligan was sentenced: happily, this Court intervened. Constitutional guaranties are not to be 'thrust to and fro and carried about with every wind of doctrine.' They were intended to be immutable so long as within our charter. Rights shielded yesterday should remain indefeasible today and tomorrow. Certain fundamentals have been set beyond experimentation; the Constitution has released them from control by the state. Again and again this Court has so declared.

Adams v. Tanner, 244 U.S. 590, 37 S.Ct. 662, 664, 61 L.Ed. 1336, L.R.A. 1917F. 1163, Ann. Cas. 1917D, 973, condemned a Washington initiative measure which undertook to destroy the business of private employment agencies because it unduly restricted individual liberty. We there said: 'The fundamental guaranties of the Constitution cannot be freely submerged if and whenever some ostensible justification is advanced and the police power invoked.'

Buchanan v. Warley, 245 U.S. 60, 38 S.Ct. 16, 18, 62 L.Ed. 149, L.R.A. 1918A, 210, Ann. Cas. 1918A, 1201, held ineffective an ordinance which forbade negroes to reside in a city block where most of the houses were occupied by whites. 'It is equally well established that the police power, broad as it is, cannot justify the passage of a law or ordinance which runs counter to the limitations of the federal Constitution; that principle has been so frequently affirmed in this court that we need not stop to cite the cases.' Southern Ry. Co. v. Virginia, 290 U.S. 190, 54 S.Ct. 148, 150, 78 L.Ed.260 (December 4, 1933): 'The claim that the questioned statute was enacted under the police power of the state, and therefore is not subject to the standards applicable to legislation under other powers, conflicts with the firmly established rule that every state power is limited by the inhibitions of the Fourteenth Amendment.'

Adkins v. Children's Hospital, 261 U.S. 525, 545, 43 S.Ct. 394, 396, 67 L.Ed. 785, 24 A.L.R. 1238: 'That the right to contract about one's affairs is a part of the liberty of the individual protected by this clause (Fifth Amendment) is settled by the decisions of this court and is no longer open to question.'

Meyer v. Nebraska, 262 U.S. 390, 399, 43 S.Ct. 625, 626, 67 L.Ed. 1042, 29 A.L.R. 1446, held invalid a state enactment (1919), which forbade the teaching in schools of any language other than English. 'While this court has not attempted to define with exactness the liberty thus guaranteed, the term has received much consideration and some of the included things have been definitely stated. Without doubt, it denotes not merely freedom from bodily restraint but also the right of the individual to contract, to engage in any of the common occupations of life, to acquire useful knowledge, to marry, establish a home and bring up children, to worship God according to the dictates of his own conscience, and generally to enjoy those privileges long recognized at common law as essential to the orderly pursuit of happiness by free men.'

Schlesinger v. Wisconsin, 270 U.S. 230, 240, 46 S.Ct. 260, 261, 70 L.Ed. 557: 'The state is forbidden to deny due process of law or the equal protection of the laws for any purpose whatsoever.'

Near v. Minnesota, 283 U.S. 697, 51 S.Ct. 625, 75 L.Ed. 1357, overthrew a Minnesota statute designed to protect the public against obvious evils incident to the business of regularly publishing malicious, scandalous and defamatory matters, because of conflict with the Fourteenth Amendment.

In the following, among many other cases, much consideration has been given to this subject: United States v. L. Cohen Grocery Co., 255 U.S. 81, 88, 41 S.Ct. 298, 65 L.Ed. 516, 14 A.L.R. 1045; Wolff Co. v. Industrial Court, 262 U.S. 522, 43 S.Ct. 630, 67 L.Ed. 1103, 27 A.L.R. 1280; and Id., 267 U.S. 552, 45 S.Ct. 441, 69 L.Ed. 785; Pierce v. Society of Sisters, 268 U.S. 510, 45 S.Ct. 571, 69 L.Ed. 1070, 39 A.L.R. 468; Tyson & Brother v. Banton, 273 U.S. 418, 47 S.Ct. 426, 71 L.Ed. 718, 58 A.L.R. 1236; Fairmont Creamery Co. v. Minnesota, 274 U.S. 1, 47 S.Ct. 506, 71 L.Ed. 893, 52 A.L.R. 163; Ribnik v. McBride, 277 U.S. 350, 48 S.Ct. 545, 72 L.Ed. 913, 56 A.L.R. 1327; Williams v. Standard Oil Co., 278 U.S. 235, 49 S.Ct. 115, 73 L.Ed. 287, 60 A.L.R. 596; Sterling v. Constantin, 287 U.S. 378, 53 S.Ct. 190, 77 L.Ed. 375. All stand in opposition to the views apparently approved below.

If validity of the enactment depends upon emergency, then to sustain this conviction we must be able to affirm that an adequate one has been shown by competent evidence of essential facts. The asserted right is federal. Such rights may demand and often have received affirmation and protection here. They do not vanish simply because the power of the state is arrayed against them. Nor are they enjoyed in subjection to mere legislative findings.

If she relied upon the existence of emergency, the burden was upon the state to establish it by competent evidence. None was presented at the trial. If necessary for appellant to show absence of the asserted conditions, the little grocer was helpless from the beginning—the practical difficulties were too great for the average man.

What circumstances give force to an 'emergency' statute? In how much of the state must they obtain? Everywhere, or will a single county suffice? How many farmers must have been impoverished or threatened violence to create a crisis of sufficient gravity? If three days after this act became effective another 'very grievous murrain' had descended and half of the cattle had died, would the emergency then have ended, also the prescribed rates? If prices for agricultural products become high can consumers claim a crisis exists and demand that the Legislature fix less ones? Or are producers alone to be considered, consumers neglected? To these questions we have no answers. When emergency gives potency, its subsidence must disempower; but no test for its presence or absence has been offered. How is an accused to know when some new rule of conduct arrived, when it will disappear?

It is argued that the report of the Legislative Committee, dated April 10, 1933, disclosed the essential facts. May one be convicted of crime upon such findings? Are federal rights subject to extinction by reports of committees? Heretofore, they have not been.

Apparently the Legislature acted upon this report. Some excerpts from it follow. We have no basis for determining whether the findings of the committee or Legislature are correct or otherwise. The court below refrained from expressing any opinion in that regard, notwithstanding its declaration 'that legislative authority to abridge property rights and freedom of contract can be justified only by exceptional circumstances and even then by reasonable regulation only and that legislative conclusions based on findings of fact are subject to judicial review.' On the other hand it asserted: 'This court should consider only the legitimacy of the conclusions drawn from the facts found.'

In New York there are 12,000,000 possible consumers of milk; 130,000 farms produce it. The average daily output approximates 9,500,000 quarts. For ten or fifteen years prior to 1929 or 1930 the per capita consumption steadily increased; so did the supply. 'Realizing the marked improvement in milk quality, the public has tended to increase its consumption of this commodity.' 'In the past two years the per capita consumption has fallen off, (possibly) 10 per cent.' 'These marked changes in the trend of consumption of fluid milk and cream have occurred in spite of drastic reductions in retail prices. The obvious cause is the reduced buying power of consumers.' 'These cycles of overproduction and underproduction which average about 15 years in length, are explained by the human tendency to raise too many heifers when prices of cows are high and too few when prices of cows are low. A period of favorable prices for milk leads to the raising of more than the usual number of heifers, but it is not until seven or eight years later that the trend is reversed as a result of the falling prices of milk and cows.' 'Farmers all over the world raise too many heifers whenever cows pay and raise too few heifers when cows do not pay.'

'During the years 1925 to 1930 inclusive, the prices which the farmers of the state received for milk were favorable as compared with the wholesale prices of all commodities. They were even more favorable as compared with the prices received for other farm products, for not only in New York but throughout the United States the general level of prices of farm products has been below that of other prices since the World War.'

'The comparatively favorable situation enjoyed by the milk producers had an abrupt ending in 1932. Even before that, in 1930 and 1931, milk prices dropped very rapidly.' 'The prices which farmers received for milk during 1932 were much below the costs of production. After other costs were paid the producers had practically nothing left for their labor. The price received for milk in January, 1933, was little more than half the cost of production.'

'Since 1927 the number of dairy cows in the state has increased about 10 per cent. The effect of this has been to increase the surplus of milk.' 'Similar increases in the number of cows have occurred generally in the United States and are due to the periodic changes in number of heifer calves raised on the farms. Previous experience indicates that unless some form of arbitrary regulation is applied, the production of milk will not be satisfactorily adjusted to the demand for a period of several years.' 'Close adjustment of the supply of fluid milk to the demand is further hindered by the periodic changes in the number of heifers raised for dairy cows.'

'The purpose of this emergency measure is to bring partial relief to dairymen from the disastrously low prices for milk which have prevailed in recent months. It is recognized that the dairy industry of the state cannot be placed upon a profitable basis without a decided rise in the general level of commodity prices.'

Thus we are told the number of dairy cows had been increasing and that favorable prices for milk bring more cows. For two years notwithstanding law prices the per capita consumption had been falling. 'The obvious cause is the reduced buying power of consumers.' Notwithstanding the low prices, farmers continued to produce a large surplus of wholesome milk for which there was no market. They had yielded to 'the human tendency to raise too many heifers' when prices were high and 'not until seven or eight years' after 1930 could one reasonably expect a reverse trend. This failure of demand had nothing to do with the quality of the milk—that was excellent. Consumers lacked funds with which to buy. In consequence the farmers became impoverished and their lands depreciated in value. Naturally they became discontented.

The exigency is of the kind which inevitably arises when one set of men continue to produce more than all others can buy. The distressing result to the producer followed his ill-advised but voluntary efforts. Similar situations occur in almost every business. If here we have an emergency sufficient to empower the Legislature to fix sales prices, then whenever there is too much or too little of an essential thing—whether of milk or grain or pork or coal or shoes or clothes—constitutional provisions may be declared inoperative and the 'anarchy and despotism' prefigured in Milligan's Case are at the door. The futility of such legislation in the circumstances is pointed out below.

Block v. Hirsh, 256 U.S. 135, 41 S.T. 458, 65 L.Ed. 865, 16 A.L.R. 165, and Marcus Brown Holding Co. v. Feldman, 256 U.S. 170, 41 S.Ct. 465, 65 L.Ed. 877, are much relied on to support emergency legislation. They were civil proceedings; the first to recover a leased building in the District of Columbia; the second to gain possession of an apartment house in New York. The unusual conditions grew out of the World War. The questioned statutes made careful provision for protection of owners. These cases were analyzed and their inapplicability to circumstances like the ones before us was pointed out in Tyson v. Banton, 273 U.S. 418, 47 S.Ct. 426, 71 L.Ed. 718, 58 A.L.R. 1236. They involved peculiar facts and must be strictly limited. Pennsylvania Coal Co. v. Mahon, 260 U.S. 393, 416, 43 S.Ct. 158, 160, 67 L.Ed. 322, 28 A.L.R. 1321, said of them: 'The late decisions upon laws dealing with the congestion of Washington and New York, caused by the war, dealt with laws intended to meet a temporary emergency and providing for compensation determined to be reasonable by an impartial board. They went to the verge of the law but fell far short of the present act.'

Is the milk business so affected with public interest that the Legislature may prescribe prices for sales by stores? This Court has approved the contrary view; has emphatically declared that a state lacks power to fix prices in similar private businesses. United States v. Cohen Grocery Co., 255 U.S. 81, 41 S.Ct. 298, 65 L.Ed. 516, 14 A.L.R. 1045; Adkins v. Children's Hospital, 261 U.S. 525, 43 S.Ct. 394, 67 L.Ed. 785, 24 A.L.R. 1238; Wolff Packing Co. v. Industrial Court, 262 U.S. 522, 43 S.Ct. 630, 67 L.Ed. 1103, 27 A.L.R. 1280; Tyson & Brother v. Banton, 273 U.S. 418, 47 S.Ct. 426, 71 L.Ed. 718, 58 A.L.R. 1236; Fairmont Creamery Co. v. Minnesota, 274 U.S. 1, 47 S.Ct. 506, 71 L.Ed. 893, 52 A.L.R. 163; Ribnik v. McBride, 277 U.S. 350, 48 S.Ct. 545, 72 L.Ed. 913, 56 A.L.R. 1327; Williams v. Standard Oil Co., 278 U.S. 235, 49 S.Ct. 115, 73 L.Ed. 287, 60 A.L.R. 596; New State Ice Co. v. Liebmann, 285 U.S. 262, 52 S.Ct. 371, 76 L.Ed. 747; Sterling v. Constantin, 287 U.S. 378, 396, 53 S.Ct. 190, 77 L.Ed. 375.

Wolff Packing Co. v. Industrial Court, 262 U.S. 522, 537, 43 S.Ct. 630, 633, 67 L.Ed. 1103, 27 A.L.R. 1280: Here the state statute undertook to destroy the freedom to contract by parties engaged in so-called 'essential' industries. This Court held that she had no such power. 'It has never been supposed, since the adoption of the Constitution, that the business of the butcher, or the baker, the tailor, the wood chopper, the mining operator, or the miner was clothed with such a public interest that the price of his product or his wages could be fixed by state regulation. * * * An ordinary producer, manufacturer, or shopkeeper may sell or not sell as he likes.' On a second appeal, 267 U.S. 552, 569, 45 S.Ct. 441, 445, 69 L.Ed. 785, the same doctrine was restated: 'The system of compulsory arbitration which the act establishes is intended to compel, and if sustained will compel, the owner and employees to continue the business on terms which are not of their making. It will constrain them, not merely to respect the terms if they continue the business, but will constrain them to continue the business of those terms. True, the terms have some qualifications, but as shown in the prior decision the qualifications are rather illusory and do not subtract much from the duty imposed. Such a system infringes the liberty of contract and rights of property guaranteed by the due process of law clause of the Fourteenth Amendment. 'The established doctrine is that this liberty may not be interfered with, under the guise of protecting the public interest, by legislative action which is arbitrary or without reasonable relation to some purpose within the competency of the state to effect."

Fairmont Creamery Co. v. Minnesota, 274 U.S. 1, 9, 47 S.Ct. 506, 508, 71 L.Ed. 893, 52 A.L.R. 163: A statute commanded buyers of cream to adhere to uniform prices fixed by a single transaction. 'May the state, in order to prevent some strong buyers of cream from doing things which may tend to monopoly, inhibit plaintiff in error from carrying on its business in the usual way heretofore regarded as both moral and beneficial to the public and not shown now to be accompanied by evil results as ordinary incidents? Former decisions here require a negative answer. We think the inhibition of the statute has no reasonable relation to the anticipated evil—high bidding by some with purpose to monopolize or destroy competition. Looking through form to substance, it clearly and unmistakably infringes private rights, whose exercise does not ordinarily produce evil consequences, but the reverse.'

Williams v. Standard Oil Co., 278 U.S. 235, 239, 49 S.Ct. 115, 116, 73 L.Ed. 287, 60 A.L.R. 596: The State of Tennessee was declared without power to prescribe prices at which gasoline might be sold.' It is settled by recent decisions of this court that a state Legislature is without constitutional power to fix prices at which commodities may be sold, services rendered, or property used, unless the business or property involved is 'affected with a public interest." Considered affirmatively, 'it means that a business or property, in order to be affected with a public interest, must be such or be so employed as to justify the conclusion that it has been devoted to a public use and its use thereby in effect granted to the public. * * * Negatively, it does not mean that a business is affected with a public interest merely because it is large or because the public are warranted in having a feeling of concern in respect of its maintenance.'

New State Ice Co. v. Liebmann, 285 U.S. 262, 277, 52 S.Ct. 371, 374, 76 L.Ed. 747: Here Oklahoma undertook the control of the business of manufacturing and selling ice. We denied the power so to do. 'It is a business as essentially private in its nature as the business of the grocer, the dairyman, the butcher, the baker, the shoemaker, or the tailor. * * * And this court has definitely said that the production or sale of food or clothing cannot be subjected to legislative regulation on the basis of a public use.'

Regulation to prevent recognized evils in business has long been upheld as permissible legislative action. But fixation of the price at which A, engaged in an ordinary business, may sell, in order to enable B, a producer, to improve his condition, has not been regarded as within legislative power. This is not regulation, but management, control, dictation—it amounts to the deprivation of the fundamental right which one has to conduct his own affairs honestly and along customary lines. The argument advanced here would support general prescription of prices for farm products, groceries, shoes, clothing, all the necessities of modern civilization, as well as labor, when some Legislature finds and declares such action advisable and for the public good. This Court has declared that a state may not by legislative fiat convert a private business into a public utility. Michigan Comn. v. Duke, 266 U.S. 570, 577, 45 S.Ct. 191, 69 L.Ed. 445, 36 A.L.R. 1105; Frost Trucking Co. v. R.R. Comn., 271 U.S. 583, 592, 46 S.Ct. 605, 70 L.Ed. 1101, 47 A.L.R. 457; Smith v. Cahoon, 283 U.S. 553, 563, 51 S.Ct. 582, 75 L.Ed. 1264. And if it be now ruled that one dedicates his property to public use whenever he embarks on an enterprise which the Legislature may think it desirable to bring under control, this is but to declare that rights guaranteed by the Constitution exist only so long as supposed public interest does not require their extinction. To adopt such a view, of course, would put an end to liberty under the Constitution.

Munn v. Illinois (1876) 94 U.S. 113, 24 L.Ed. 77, has been much discussed in the opinions referred to above. And always the conclusion was that nothing there sustains the notion that the ordinary business of dealing in commodities is charged with a public interest and subject to legislative control. The contrary has been distinctly announced. To undertake now to attribute a repudiated implication to that opinion is to affirm that it means what this Court has declared again and again was not intended. The painstaking effort there to point out that certain businesses like ferries, mills, etc., were subject to legislative control at common law and then to show that warehousing at Chicago occupied like relation to the public would have been pointless if 'affected with a public interest' only means that the public has serious concern about the perpetuity and success of the undertaking. That is true of almost all ordinary business affairs. Nothing in the opinion lends support, directly or otherwise to the notion that in times of peace a legislature may fix the price of ordinary commodities—grain, meat, milk, cotton, etc.

Of the assailed statute the Court of Appeals says: 'It first declares that milk has been selling too cheaply in the state of New York, and has thus created a temporary emergency; this emergency is remedied by making the sale of milk at a low price a crime; the question of what is a low price is determined by the majority vote of three officials.' Also: 'With the wisdom of the legislation we have naught to do. It may be vain to hope by laws to oppose the general course of trade.' Maybe, because of this conclusion, it said nothing concerning the possibility of obtaining increase of prices to producers—the thing definitely aimed at—through the means adopted.

But plainly, I think, this Court must have regard to the wisdom of the enactment. At least, we must inquire concerning its purpose and decide whether the means proposed have reasonable relation to something within legislative power—whether the end is legitimate, and the means appropriate. If a statute to prevent conflagrations, should require householders to pour oil on their roofs as a means of curbing the spread of fire when discovered in the neighborhood, we could hardly uphold it. Here, we find direct interference with guaranteed rights defended upon the ground that the purpose was to promote the public welfare by increasing milk prices at the farm. Unless we can affirm that the end proposed is proper and the means adopted have reasonable relation to it, this action is unjustifiable.

The court below has not definitely affirmed this necessary relation; it has not attempted to indicate how higher charges at stores to impoverished customers when the out put is excessive and sale prices by producers are unrestrained, can possibly increase receipts at the farm. The Legislative Committee pointed out as the obvious cause of decreased consumption, notwithstanding low prices, the consumers' reduced buying power. Higher store prices will not enlarge this power; nor will they decrease production. Low prices will bring less cows only after several years. The prime causes of the difficulties will remain. Nothing indicates early decreased output. Demand at low prices being wholly insufficient, the proposed plan is to raise and fix higher minimum prices at stores and thereby aid the producer whose output and prices remain unrestrained! It is not true as stated that 'the State seeks to protect the producer by fixing a minimum price for his milk.' She carefully refrained from doing this; but did undertake to fix the price after the milk had passed to other owners. Assuming that the views and facts reported by the Legislative Committee are correct, it appears to me wholly unreasonable to expect this legislation to accomplish the proposed end—increase of prices at the farm. We deal only with Order No. 5 as did the court below. It is not merely unwise; it is arbitrary and unduly oppressive. Better prices may follow but it is beyond reason to expect them as the consequent of that order. The Legislative Committee reported: 'It is recognized that the dairy industry of the State cannot be placed upon a profitable basis without a decided rise in the general level of commodity prices.'

Not only does the statute interfere arbitrarily with the rights of the little grocer to conduct his business according to standards long accepted—complete destruction may follow; but it takes away the liberty of 12,000,000 consumers to buy a necessity of life in an open market. It imposes direct and arbitrary burdens upon those already seriously impoverished with the alleged immediate design of affording special benefits to others. To him with less than 9 cents it says: You cannot procure a quart of milk from the grocer although he is anxious to accept what you can pay and the demands of your household are urgent! A superabundance; but no child can purchase from a willing storekeeper below the figure appointed by three men at headquarters! And this is true although the storekeeper himself may have bought from a willing producer at half that rate and must sell quickly or lose his stock through deterioration. The fanciful scheme is to protect the farmer against undue exactions by prescribing the price at which milk disposed of by him at will may be resold!

The statement by the court below that, 'Doubtless the statute before us would be condemned by an earlier generation as a temerarious interference with the rights of property and contract * * * with the natural law of supply and demand,' is obviously correct. But another, that 'statutes aiming to * * * stimulate the production of a vital food product by fixing living standards of prices for the producer, are to be interpreted with that degree of liberality which is essential to the attainment of the end in view,' conflicts with views of constitutional rights accepted since the beginning. An end although apparently desirable cannot justify inhibited means. Moreover, the challenged act was not designed to stimulate production—there was too much milk for the demand and no prospect of less for several years. Also 'standards of prices' at which the producer might sell were not prescribed. The Legislature cannot lawfully destroy guaranteed rights of one man with the prime purpose of enriching another, even if for the moment, this may seem advantageous to the public. And the adoption of any 'concept of jurisprudence' which permits facile disregard of the Constitution as long interpreted and respected will inevitably lead to its destruction. Then, all rights will be subject to the caprice of the hour; government by stable laws will pass.

The somewhat misty suggestion below that condemnation of the challenged legislation would amount to holding 'that the due process clause has left milk producers unprotected from oppression,' I assume, was not intended as a material contribution to the discussion upon the merits of the cause. Grave concern for embarrassed farmers is everywhere; but this should neither obscure the rights of others nor obstruct judicial appraisement of measures proposed for relief. The ultimate welfare of the producer, like that of every other class, requires dominance of the Constitution. And zealously to uphold this in all its parts is the highest duty intrusted to the courts.

The judgment of the court below should be reversed.

Mr. Justice VAN DEVANTER, Mr. Justice SUTHERLAND, and Mr. Justice BUTLER authorize me to say that they concur in this opinion.
