v.
MAYES, MARSHALL OF JACKSON COUNTY, MISSOURI.
No. 597.
Supreme Court of United States.
Argued December 13, 14, 1910.
Decided January 9, 1911.
ERROR TO THE SUPREME COURT OF THE STATE OF MISSOURI.
*271 Mr. Frank Hagerman, with whom Mr. Kimbrough Stone was on the brief, for plaintiff in error.
Mr. Elliott W. Major, Attorney General of the State of Missouri, with whom Mr. John M. Atkinson was on the brief, for defendant in error.
*277 MR. JUSTICE HARLAN delivered the opinion of the court.
The plaintiff in error was proceeded against by information filed in the Criminal Court of Jackson County, Missouri, under a statute of Missouri, which was passed June 8, 1909, and is entitled "An act to prevent fraud in the purchase and sale of grain and other commodities." The statute reads: "§ 1. Every sale of grain, seed, hay or coal shall be made on the basis of the actual weight thereof, and any purchaser of grain, seed, hay or coal, who shall deduct any amount from the actual weight or measure thereof under claim of right to do so by reason of any custom or rule of a Board of Trade or any pretense whatsoever, shall be deemed guilty of a misdemeanor, and shall be subject to a fine of not less than ten dollars nor more than one hundred dollars for each and every offense. § 2. No agent or broker selling any grain, seed, hay or coal shall have authority, under claim or right to do so by reason of any custom or rule of Board of Trade, to sell any grain, seed, hay or coal only on the basis of the actual weight thereof, and any contract of sale of any grain, seed, hay or coal made in violation of this act shall be null and void." Mo. Sess. Acts, 1909, p. 519; Mo. Rev. Stat., §§ 11969, 11970.
The information charged that the accused, on the first day of September, 1909, at the County of Jackson, State of Missouri, purchased from one James Anderson a carload of wheat, by weight, and unlawfully took and deducted *278 from the actual weight one hundred pounds, pretending and claiming the right to make such deduction, and to have and keep the said one hundred pounds so deducted free of charge and cost to him, under and by virtue of a rule and custom of the Board of Trade of Kansas City, Missouri.
Having been arrested on a capias and being held in custody by the defendant as Marshal, the accused presented to the Criminal Court an application for a writ of habeas corpus  claiming that he was deprived of his liberty in violation of the Fourteenth Amendment of the Constitution of the United States. The application was denied, but it was subsequently granted by the Supreme Court of the State. The latter court upon final hearing also denied the application, and ordered that the petitioner be remanded to the custody of the Marshal. The case is now here for review, upon assignments of error which question the constitutional validity of the statute under the Fourteenth Amendment.
The case was heard upon an agreed statement of facts, the parties reserving all questions as to the relevancy of any particular fact therein stated. As the case is of some importance it will be appropriate to set forth the above statement in full, as follows: "Without admission of either party as to the relevancy of any particular fact herein set forth, the following facts are agreed between the parties: There are competitive grain markets at Galveston, Texas; Chicago, Illinois; Omaha, Nebraska; Atchison and Wichita, Kansas, and St. Louis, St. Joseph and Kansas City, Missouri. That Kansas City is a primary grain market. That a very slight difference in price or condition will influence the market course of grain. That the Board of Trade of Kansas City, Missouri, is a voluntary organization of buyers and sellers of grain and provisions, supported by dues and assessments and maintained for the purpose of furnishing a marketing place *279 where such persons can meet and, under rules of safety and convenience, transact such business. Its objects are: `To maintain a Board of Trade, to promote uniformity in the customs and usages of merchants; to inculcate principles of justice and equity in business; to facilitate the speedy adjustment of business disputes; to inspire confidence in the business methods and integrity of the parties hereto; to collect and disseminate valuable commercial and economic information, and generally to secure to its members the benefits of co-operation in the furtherance of their legitimate pursuits, and to promote the general welfare of Kansas City.' Its members are governed by rules and regulations, enacted by the members, and which form part of the written contract of association between them. This organization provides for the exclusive use of its members a trading floor, where grain is bought and sold only under and according to said rules. Three of said rules are: `§ 16. The weight Supervising Committee shall have supervision, through the Weight Department, of the unloading of all cars unloaded at all elevators, mills, warehouses, transfer and team tracks, within the jurisdiction of this Board, and shall cause the same to be thoroughly swept and cleaned when unloaded. Sweeping or cleaning of cars subsequently by any operator or employe of any elevator, mill, warehouse, transfer or team tracks, or by any person or persons under agreement with the same; or the buying or receiving of any such sweepings or cleanings by any member of this Association is prohibited. § 17. Violations of any of the provisions of section 16 of this article shall subject the members so violating to a fine of $50.00 for the first offense, to a fine of $100.00 for the second offense, to expulsion and forfeiture of membership for the third offense. § 18. On all grain bought by members of the Kansas City Board of Trade, and on which Kansas City unloading weights are given, an allowance of one hundred lbs. per car shall be *280 made to the buyer, to cover loss on account of dirt and other foreign matter.' That said Board of Trade maintains a bureau of weights, which strictly enforces rule 16. That rules 16 and 17 were enacted to secure to the seller full weight of the entire contents of the car and rule 18 to secure the buyer from loss through dirt and foreign matter in or swept out with the grain, which was unloaded at Kansas City. Before grain is sold it is graded. One of the considerations in grading is the dirt and foreign matter in the grain. Experience had shown that there is a loss from dirt and foreign matter, varying with different cars, which is not fully taken care of in the grade. That there is no method in use of accurately determining the percentage of such foreign matter and dirt, and the one hundred pound quantity was taken as a fair average. The members of said Board of Trade buy and sell sometimes as commission men for outsiders and sometimes for their own account, and it is impossible to tell without inquiry whether a buyer or seller is acting for himself or for some one else. The buying and selling of grain on the floor of said Board of Trade is as in all other markets, based upon the constantly and rapidly fluctuating market prices in that and the other principal grain markets. There is no time nor opportunity to ascertain the capacity (principal or agent) in which a member is acting when he buys or sells, and, if he be in reality acting as agent, no opportunity to investigate the financial standing of the real principal. Because of this condition and also to secure the prompt and faithful performance of all such contracts of sale there is a rule of said Board of Trade forbidding the disclosure of outside principals and holding the member in all cases as the principal. There are also rules making a membership responsible for the faithful performance of such contracts. That the State Railroad and Warehouse Commission has in force a rule requiring cars unloaded at Kansas City to be cleanly swept. That *281 the method of making the reduction is to weigh the loaded car; then after emptying and cleanly sweeping the car, to weigh the car; the difference in these two weights is entered on the account sales as the weight of the carload of grain, the deduction of one hundred pounds being also noted on that slip and settlement made for this balance. That is, the weight of the entire contents of the car is shown, and also the one hundred pounds' deduction on the face of the account sales given the seller. That upon the first day of September, 1909, your petitioner [House] bought upon the trading floor of said Board of Trade, and from a member thereof, a carload of wheat on Kansas City unloading weights. In accordance with the above method and under said rule 18, he deducted one hundred pounds and made settlement for the balance. The member selling this grain did not own it, but was acting as a commission man. He, however, dealt with your petitioner as in his own right, and your petitioner had no notice or knowledge that such seller was not the real owner of the grain. Nothing had been said between the member selling and his principal as to the allowance of the one hundred pounds. Both your petitioner and the seller understood at the time of sale that it was made subject to this rule."
An extended discussion of the general question of constitutional law raised by the assignments of error is rendered unnecessary by former decisions of this court. There are certain fundamental principles which those cases recognize and which are not open to dispute. In our opinion, they sustain the power of the State to enact the statute in question. Briefly stated, those principles are: That the Government created by the Federal Constitution is one of enumerated powers, and cannot, by any of its agencies, exercise an authority not granted by that instrument, either in express words or by necessary implication; that a power may be implied when necessary *282 to give effect to a power expressly granted; that while the Constitution of the United States and the laws enacted in pursuance thereof, together with any treaties made under the authority of the United States, constitute the Supreme Law of the Land, a State of the Union may exercise all such governmental authority as is consistent with its own constitution, and not in conflict with the Federal Constitution; that such a power in the State, generally referred to as its police power, is not granted by or derived from the Federal Constitution but exists independently of it, by reason of its never having been surrendered by the State to the General Government; that among the powers of the State, not surrendered  which power therefore remains with the State  is the power to so regulate the relative rights and duties of all within its jurisdiction so as to guard the public morals, the public safety and the public health, as well as to promote the public convenience and the common good; and that it is with the State to devise the means to be employed to such ends, taking care always that the means devised do not go beyond the necessities of the case, have some real or substantial relation to the objects to be accomplished, and are not inconsistent with its own constitution or the Constitution of the United States. The cases which sanction these principles are numerous, are well known to the profession, and need not be here cited.
Applying these principles to the present case we cannot say that the statute in question is in conflict with the Constitution of the United States. The Supreme Court of Missouri well observed that the object of the statute was to prevent the enforcement of a rule of a board of trade, under the ordinary operation of which unfair and fraudulent practices occur, or would most probably occur, in the sale of grain and the other commodities named. That court said:
"The provision of the act which petitioner is charged *283 with having violated is that part thereof which prohibits any purchaser of grain from deducting any amount from the actual weight under a claim of right to do so by reason of any custom or rule of the Board of Trade and it is the rule of the Kansas City Board of Trade at which this act is really aimed. The petitioner claims that this act is unconstitutional because it prohibits him from deducting an arbitrary amount, to wit, one hundred pounds from each and every car of grain, irrespective of the fact whether or not it actually contains any dirt or foreign substance. While conceding in the agreed statement of facts that there is no method of accurately determining the percentage of such foreign matter and dirt he assumes that there will be an average of one hundred pounds to each car. He admits that in grading wheat, dirt and foreign matter are taken into account in determining the value of the grain, but the Kansas City Board of Trade have arbitrarily added to this and deducted one hundred pounds from every car, so that if A shipped a car of grain to Kansas City to a member of the Board of Trade, which was entirely free from dirt or foreign matter, under this rule one hundred pounds would be deducted and he loses the value of this one hundred pounds and receives no compensation therefor, but is told that he must submit to this because some other shipper may ship a carload of grain containing two hundred pounds of dirt or foreign matter, thus the grain of A which contains no dirt is taken without compensation and the man who shipped a carload of grain with two hundred pounds of dirt suffers a deduction of only one hundred pounds. . . . 1 Bishop's New Crim. Laws, 234. It prohibits merely the taking of one man's property by another without compensation. It imposes no unjust burden upon the purchaser but simply inhibits his deduction from the wheat he purchases, a part thereof which he would take without paying the seller therefor by virtue, not of any *284 agreement with the seller, but by virtue of a rule made by an association of which he is a member."
Again, the Supreme Court of the State says: "Petitioner insists that by prohibiting him from making the deduction of one hundred pounds his property is taken without due process of law. We agree with the Attorney General that he has reversed the conditions. To strike down this act will be to permit him to continue to take the shipper's property without due process of law, and without any compensation therefor. Without further elaboration, we are of the opinion that this act is a valid one and it is wisely aimed to prevent unjust and unfair practice and to repeal and nullify a rule of the Board of Trade which is unjust and unfair and contrary to good morals and fair dealings, and the act offends against no provision of the Constitution."
Reference has been made to the fact that the Board of Trade of Kansas City is a voluntary association of individuals who perform great service to the public, and that its purpose is to enforce, as between its members, a high standard of business dealings. Let all this be granted, and yet it must be held that the Board, in the management of its affairs, has such close and constant relations to the general public, that the conduct of its business may be regulated by such means, not arbitrary or unreasonable in their nature, as may be found by the State necessary or needful to protect the people against unfair practices that may likely occur from time to time. Such regulations do not, in any true sense, interfere with that "liberty of contract" which the individual members of the Board of Trade are undoubtedly entitled, under the Constitution to enjoy, without unnecessary interference from government; for, the liberty of contract which that instrument protects against invasion by the State is subject to such regulations of the character just stated, as the State may establish for the protection of the public *285 and the promotion of the general welfare. If such state regulations are not unreasonable, that is, not simply arbitrary nor beyond the necessities of the case, they are not forbidden by the Constitution of the United States. We so adjudge on both principle and authority.
The judgment of the Supreme Court of Missouri is
Affirmed.
MR. JUSTICE McKENNA concurring.
THE CHIEF JUSTICE and myself concur in the judgment solely on the ground that it is competent for the State of Missouri to provide that, in the absence of an express contract to which the owner of the articles sold on the Board is a party, the rule of the Kansas City Board of Trade shall not prevail.
