v.
PEOPLE OF THE STATE OF NEW YORK.
No. 28.
Supreme Court of United States.
Argued November 5, 1912.
Decided December 2, 1912.
ERROR TO THE COUNTY COURT OF MONROE COUNTY, IN THE STATE OF NEW YORK.
*261 Mr. Percival D. Oviatt for plaintiff in error.
Mr. Freeman F. Zimmerman for defendant in error.
*264 MR. JUSTICE PITNEY delivered the opinion of the court.
The plaintiff in error pleaded guilty to an indictment charging him with "the crime of criminally receiving stolen property," in that he, being a dealer in and collector of junk, metals and second-hand materials, did feloniously *265 buy and receive, from persons named, certain copper wire, "the same then and there consisting of copper wire used by and belonging to a telephone company, to wit, used by and being the goods, chattels and personal property of the Bell Telephone Company, of Buffalo, . . . then lately stolen, taken and carried away from the possession of the said Bell Telephone Company, . .. without ascertaining by diligent inquiry that the said persons so selling and delivering the same had a legal right to do so."
The indictment was founded upon Chap. 326 of the Laws of 1903 of the State of New York, amending § 550 of the Penal Code. The section as amended reads as follows:
"SEC. 550. Criminally receiving property.  A person, who buys or receives any stolen property, or any property which has been wrongfully appropriated in such a manner as to constitute larceny according to this chapter, knowing the same to have been stolen or so dealt with, or who corruptly, for any money, property, reward, or promise or agreement for the same, conceals, withholds, or aids in concealing or withholding any property, knowing the same to have been stolen, or appropriated wrongfully in such a manner as to constitute larceny under the provisions of this chapter, if such misappropriation has been committed within the state, whether such property were stolen or misappropriated within or without the state, [or who being a dealer in or collector of junk, metals or second-hand materials, or the agent, employe, or representative of such dealer or collector, buys or receives any wire, cable, copper, lead, solder, iron or brass used by or belonging to a railroad, telephone, telegraph, gas or electric light company without ascertaining by diligent inquiry, that the person selling or delivering the same has a legal right to do so,] is guilty of criminally receiving such property, and is punishable, by imprisonment in a state prison for not more than *266 five years, or in a county jail for not more than six months, or by a fine of not more than two hundred and fifty dollars, or by both such fine and imprisonment."
The words inclosed in brackets were added by the amendment of 1903, which made no other change in the section. The section as amended was reenacted in the Penal Code as § 1308.
Having pleaded guilty, the plaintiff in error moved in arrest of judgment, upon the ground of the unconstitutionality of the amendment of 1903, and this motion having been denied, sentence of fine and imprisonment was imposed, whereupon he took an appeal to the Appellate Division, and from an adverse ruling in that court he appealed to the Court of Appeals, which court sustained the statute against the constitutional objections and affirmed the judgment of conviction. 197 N.Y. 394.
The record having been remitted to the county court, the present writ of error was taken. The errors relied upon are that the courts of the State of New York erred, because they ought to have decided that the amendment of 1903 to § 550 of the Penal Code was in conflict with the Fourteenth Amendment, in that (a) it abridged the privileges and immunities of the plaintiff in error; (b) deprived him of his liberty and property without due process of law, and (c) denied to him the equal protection of the laws.
No serious argument was made to support the contention that the act in any way abridged the privileges or immunities of the plaintiff in error as a citizen of the United States. This part of the prohibition of the Fourteenth Amendment refers only to such privileges and immunities as pertain to citizenship of the United States, as distinguished from state citizenship. Slaughter House Cases, 16 Wall. 36, 74, 80. We are unable to see that the statute under consideration, or its enforcement in the case at hand, even if the act be fairly open to any or all of the criticisms that are made upon it, abridges in the *267 least any privilege or immunity that arises out of the national citizenship of the plaintiff in error.
The argument is thus narrowed to a consideration of the statute in the light of the "due process of law" and "equal protection" clauses.
The New York Court of Appeals in the present case construed the amendment of 1903 as applying only to stolen property, and as putting upon the dealer in junk, metal or second-hand materials, not the burden of ascertaining at his peril that the person selling or delivering the wire or other property specified, has a legal right to do so, but only the duty of making diligent inquiry for the purpose of ascertaining whether the person selling or delivering it has such legal right.
Counsel for the plaintiff in error argues, first, that the act in question is unconstitutional even as thus interpreted; and this on the grounds that the previous laws relating to criminally receiving stolen property, were adequate to protect against the evils involved and that the act of 1903 is unreasonable and oppressive and an undue interference with the liberty of contract; that since the act applies only to dealers in metals, etc., it is class legislation, based upon arbitrary distinctions; and that the statute protects the property only of railroad, telephone, gas and electric companies, and for this reason likewise is based upon arbitrary distinctions.
In support of this argument, counsel points out that, without the amendment of 1903, the Penal Code provides that anyone who buys or receives property, knowing it to be stolen, is guilty of a felony; that anyone who conceals or withholds or aids in the concealment or withholding of such property is guilty of a felony; that the decisions of the courts of New York hold that actual knowledge of the fact that the property is stolen is unnecessary, and that anything in the circumstances that would put an honest or prudent man upon inquiry is sufficient to warrant *268 a conviction. People v. Dowling, 84 N.Y. 478, 485; People v. Wilson, 151 N.Y. 403. It is also pointed out that chapter 308 of the Laws of 1903 compels every junk dealer (except in cities of the first class), to obtain a license, provides that when such a dealer purchases any pig iron, pig metal, copper wire, or brass car journals, he shall cause a statement to be subscribed by the seller as to when, where, and from whom he obtained the property, which statement must be filed with the chief of police; and that when a junk dealer purchases the property described, he must keep such purchase absolutely separate and distinct, without change or mutilation, for a period of five days after the purchase, and must tag it with a tag bearing the particulars of the purchase. And that all cities of the first class have dealt with the subject-matter through the means of local ordinances at least as comprehensive as the statute just mentioned.
Counsel, indeed, concedes the abundant right of the legislature to regulate the junk business, and admits that such regulations as those just referred to are quite within the legislative power of the State.
This concession is, we think, very properly made; and, this being so, there is little ground left for an attack upon the amendment of 1903 because of its alleged unreasonable and arbitrary requirement that a dealer in or collector of junk, metals, or second-hand materials, who buys or receives any stolen wire, cable, copper, lead, solder, iron, or brass, used by or belonging to a railroad, telephone, telegraph, gas, or electric light company, shall make diligent inquiry to ascertain that the person selling or delivering it has a legal right to do so.
When it is conceded that such a dealer may be properly subjected to punishment as a criminal if he receives stolen property without actual knowledge that it has been stolen, and merely because charged with notice of circumstances such as would have put an honest or prudent *269 man upon inquiry, it needs little argument to vindicate legislation with respect to particular kinds of personal property that the legislature in its wisdom presumably deemed to be more susceptible of theft than other property, when that legislation but adds the further requirement of diligent inquiry by the dealer with respect to the right of the seller.
It is urged as a criticism that the statute directs the junk dealer's inquiry to the question of the legal right of the seller to sell, rather than to the question of an original larceny. It ought to be unnecessary to say that if goods have in fact been stolen, a diligent inquiry into the right of the present possessor to make sale or delivery of them will very surely tend to disclose the larcenous origin of his title. Indirect questions in such a case will very probably bring out the truth as readily and as surely as the plump inquiry  "Did you steal these goods?" Or, at least, the legislature might so presume. For of course all such matters rest in legislative discretion.
Counsel suggests that diligent inquiry by a junk dealer respecting the legal right of one offering certain wire or other goods for sale might lead to perplexing questions that only a court of last resort could properly determine. The obvious answer is that a method of inquiry that would bring to light, in rare instances, even the occult and doubtful point in a vendor's title, would, if systematically adhered to, be reasonably sure in a greater number of instances to develop the fact that the goods under investigation had been acquired by theft.
We have said enough to indicate the character of the arguments employed in the effort to show that the act of 1903 is wholly arbitrary and constitutes so groundless an interference with the citizen's liberty of contract as to bring it within the denunciation of the due process of law clause of the Fourteenth Amendment. It seems to us that the object of the legislation is well within the *270 legitimate bounds of the police power of the State and sustainable upon the principles discussed in Mugler v. Kansas, 123 U.S. 623, 661, etc., of which more recent applications are to be found in Booth v. Illinois, 184 U.S. 425, 429, and Lemieux v. Young, 211 U.S. 489. See also Chicago, B. & Q. Ry. Co. v. McGuire, 219 U.S. 549, 568.
Nor can the act in question be deemed to conflict with the "equal protection" clause because it places junk dealers, etc., in a class by themselves. The argument under this head is that if property of the kinds mentioned in the act is peculiarly susceptible of theft, there is no reason that all persons should not be subjected to the same rules with reference to its purchase. This needs no answer beyond a reference to the well-known fact, alluded to by the New York Court of Appeals in its opinion herein, that junk dealers provide an important market for stolen merchandise of the kinds mentioned, and that because of their experience they are peculiarly fitted to detect whether property offered is stolen property. Plainly it cannot be said that the classification rests on no reasonable basis. It is unnecessary to rehearse the grounds upon which rests the authority of the States to resort to classification for purposes of legislation. The citation of a few recent illustrative cases will obviate extended discussion. Magoun v. Illinois Trust & Savings Bank, 170 U.S. 283, 293; Orient Ins. Co. v. Daggs, 172 U.S. 557, 562; Louisville & Nashville R.R. v. Melton, 218 U.S. 36, 52; Lindsley v. Natural Carbonic Gas Co., 220 U.S. 61, 78.
The fact that the act of 1903 has reference to the property of only railroad, telephone, gas, and electric companies, furnishes no ground for the plaintiff in error to invoke the "equal protection" clause of the Fourteenth Amendment. The failure of the legislature to extend the protection of the act to the like kinds of property when owned by manufacturers of equipment for railroads, telephone and telegraph lines, as well as when owned by the *271 companies operating such lines; or the failure to include the owners of blast furnaces and brass foundries, or other classes who, as claimed by counsel, are liable to losses by theft of articles of the like kinds, affords no footing for an attack by plaintiff in error upon the constitutionality of the act, for the reason that he does not bring himself within any of the classes that, according to the argument, are peculiarly susceptible to losses of the kind that the statute is designed to prevent, nor does he show that he has suffered any injury by reason of the failure of the legislature to extend the protection of the act to other classes of owners. Tyler v. Judges, 179 U.S. 405, 409; Hooker v. Burr, 194 U.S. 415, 419; Hatch v. Reardon, 204 U.S. 152, 160; Southern Railway Co. v. King, 217 U.S. 524, 534; Standard Stock Food Co. v. Wright, 225 U.S. 540, 550.
So far, therefore, as plaintiff in error is concerned, the legislature has simply not extended the scope of the act so far as it might properly have done. The argument under this head concedes, and must concede, that the act is beneficial as far as it goes, the complaint being that it does not go far enough. But the Federal Constitution does not require that all state laws shall be perfect, nor that the entire field of proper legislation shall be covered by a single enactment.
The Court of Appeals, in the case before us, said with respect to this topic: "The legislature is presumed to have been familiar with current history and the decisions of the courts, which show that property of a certain kind, such as copper, brass, iron, etc., is frequently stolen from railroad, telegraph, and similar corporations, which cannot adequately protect it because it is scattered through the country along extensive lines of transportation or communication, and which is exposed to view and caption by the evil minded, who find their best market in the shops of certain junk dealers."
*272 If the act required any defense against the criticism now under consideration, this expression would suffice.
It remains only to notice the second principal contention of plaintiff in error, which is that the construction placed upon the act of 1903 by the Court of Appeals is clearly erroneous, and that the situation is such that this court ought not to hold itself bound by that construction.
It is ingeniously argued that since the statute had never been judicially construed until the decision of the Court of Appeals in this case, and since that court (erroneously, it is asserted) injected into the act by construction two elements that are said not to be apparent from a literal reading  to wit, that the statute applies only to stolen property, and that the dealer need not ascertain the legal right of the seller, but need only make diligent inquiry to ascertain the same, the plaintiff in error is aggrieved by what is called the "judicial amendment" of the statute.
Although not distinctly invoking the prohibition of ex post facto laws, as contained in Art. I, § 10, cl. 1, of the Federal Constitution, the argument, if it have any basis, must be rested upon that prohibition.
It is sufficient to say that no such point appears to have been raised in the court below, although it might have been raised by an application for rehearing. Nor is any such point covered by the assignments of error in this court.
Judgment affirmed.
