The validity of this very statute of Arkansas (at least, until Congress legislates upon the subject) has already been affirmed by this court (Woods v. Carl, 203 U. S. 358, 51 L. ed. 219, 27 Sup. Ct. Rep. 99), and the validity of statutes of a somewhat similar nature has also been affirmed in the case of Allen v. Riley, 203 U. S. 347, 51 L. ed. 216, 27 Sup. Ct. Rep. 95, immediately preceding the case above cited.

It is sought to avoid the authority of our decision upon this Arkansas statute by asserting that nothing was therein decided except the validity of the 1st section of the act, and that the validity of the act when considered in connection with the 4th section was not argued or decided. The 4th section reads as follows: 'This act shall not apply to merchants and dealers who sell patented things in the usual course of business.' Other reasons for an affirmance are set up in the brief of respondent.

The grounds given for the decision by the circuit court and the circuit court of appeals differ somewhat. The circuit court says that the effect of the 4th section of the statute is to violate that portion of the 14th Amendment to the Federal Constitution which provides that no state shall deny to any person within its jurisdiction the equal protection of the laws; while the circuit court of appeals bases its judgment upon the unlawful discrimination evidenced by the act against those who are protected by a patent granted by the United States.

In 203 U. S. 358 (supra) this court held the statute valid as against an objection of the same nature as that taken herein by the circuit court of appeals. Our decision in that case had not been made at the time of the decision of this case in the courts below. The ground taken by the circuit court was not discussed in our opinion in 203 U. S., and although it might be urged that all objections to its validity arising upon the face of the statute, even if not specially discussed, were overruled by the decision, yet, assuming that the particular question now presented is still open in this court, we are of opinion that the exception contained in § 4 does not render the statute invalid. The plain purpose of the whole statute is to create and enforce a proper police regulation. Its passage showed that the legislature was of opinion that fraud and imposition were frequent in the sale of property of this nature, except in the cases mentioned in § 4, and that temptations to false representations in regard to the virtues and value of the article sold were also frequently yielded to. When the sale of the article was effected by such representations, and a note given for the amount of the sale, a transfer of the note to a bona fide purchaser for value before its maturity prevented the vendee from showing the fraud by which the sale had been accomplished. In order to reach such a transaction and to permit the vendee to show the fraud, the statute was passed. It was doubtless thought that merchants and dealers, as mentioned in the statute, while dealing with the patented things in the manner stated, would not be so likely to make representations or to engage in a fraud to effect a sale, as those covered by the statute. The various itinerant venders of patented articles, whose fluency of speech and carelessness regarding the truth of their representations might almost be said to have become proverbial, were, of course, in the mind of the legislature, and were included in this legislation. Indeed, they are the principal people to be affected by it.

The manufacturer of a patented article, who also sells it in the usual course of business in his store or factory, would probably come within the exception of § 4. He may be none the less a dealer, selling in the usual course of his business, because he is also a manufacturer of the article dealt in. Exceptional and rare cases, not arising out of the sale of patented things in the ordinary way, may be imagined where this general classification separating the merchants and dealers from the rest of the people might be regarded as not sufficiently comprehensive, because in such unforeseen, unusual, and exceptional cases the people affected by the statute ought, in strictness, to have been included in the exception. See opinion of circuit court herein, 127 Fed., supra. But we do not think the statute should be condemned on that account. It is because such imaginary and unforeseen cases are so rare and exceptional as to have been overlooked that the general classification ought not to be rendered invalid. In such case there is really no substantial denial of the equal protection of the laws within the meaning of the Amendment.

It is almost impossible, in some matters, to foresee and provide for every imaginable and exceptional case, and a legislature ought not to be required to do so at the risk of having its legislation declared void, although appropriate and proper upon the general subject upon which such legislation is to act, so long as there is no substantial and fair ground to say that the statute makes an unreasonable and unfounded general classification, and thereby denies to any person the equal protection of the laws. In a classification for governmental purposes there cannot be an exact exclusion or inclusion of persons and things. See Gulf, C. & S. F. R. Co. v. Ellis, 165 U. S. 150, 41 L. ed. 666, 17 Sup. Ct. Rep. 255, and cases cited; Missouri, K. & T. R. Co. v. May, 194 U. S. 267, 48 L. ed. 971, 24 Sup. Ct. Rep. We can see reasons for excepting merchants and dealers who sell patented things, in the usual course of business, from the provisions of the statute, and we think the failure to exempt some few others, as above suggested, ought not to render the whole statute void as resulting in an unjust and unreasonable discrimination.

The case of Connolly v. Union Sewer Pipe Co. 184 U. S. 540, 46 L. ed. 679, 22 Sup. Ct. Rep. 431, one of the cases cited by the circuit court, is not, in our opinion, applicable. The statute did not apply to agricultural products or live stock while in the hands of the producer or raiser. It was held that this exemption rendered the statute void, as denying to persons within the jurisdiction of the state the equal protection of the laws. The statute was held to create a classification of an arbitrary nature, applicable to large numbers of people, and yet not based upon any reasonable ground. Those who were exempted from its provisions were numerous and stood practically in the same relation to the subject-matter of the statute as did the other class upon whom the statute acted, and no valid reason could be given why, if one were included, the other should be exempted. The same reasons applied to all the classes, and should have led to the same results with regard to all. There was no room for a proper or fair discrimination.

We think there is a distinction, founded upon fair reasoning, which upholds the principle of exemption as contained in the 4th section, and that, consequently, the statute does not violate the 14th Amendment on the ground stated.

The case was decided by the courts below solely upon constitutional grounds, and upon those grounds the decision cannot rest. It must, therefore, be remanded, and if there be any other facts to be urged they can be presented on another trial.

The judgments of the Circuit Court and the Circuit Court of Appeals must be reversed and the case remanded to the Circuit Court for further proceedings not inconsistent with this opinion.

Reversed.
