Rasmussen v. Idaho/Opinion of the Court
The judgment of the supreme court of Idaho establishes that there is no conflict between this legislation and the Constitution of the state, and it is not within the province of this court to review that question. Merchants' & Mfrs. Bank v. Pennsylvania, 167 U.S. 461, 42 L. ed. 236, 17 Sup. Ct. Rep. 829, and cases cited in the opinion.

The single question, therefore, for our consideration, is whether this legislation conflicts with the Federal Constitution. Plaintiff in error relies largely on Hannibal & St. J. R. Co. v. Husen, 95 U.S. 465, 24 L. ed. 527. In that case the validity of an act of the state of Missouri was presented. The act provided that 'no Texas, Mexican, or Indian cattle shall be driven or otherwise conveyed into or remain in any county in this state between the 1st day of March and the 1st day of November in each year by any person or persons whatsoever.' It was held to be in conflict with the constitutional grant of power to Congress to regulate commerce between the states. In the opinion the police power of the state, the power by which the state prevents the introduction into its midst of noxious articles, was fully recognized, but attention was called to the fact that there was an absolute prohibition of the bringing in of Texas, Mexican, or Indian cattle during eight months of the year, without reference to the actual condiction of the cattle; and it was said:

'Tried by this rule, the statute of Missouri is a plain intrusion upon the exclusive domain of Congress. It is not a quarantine law. It is not an inspection law. It says to all natural persons and to all transportation companies, 'You shall not bring into the state any Texas cattle or any Mexican cattle or Indian cattle, between March 1 and December [November] 1 in any year, no matter whether they are free from disease of not; no matter whether they may do an injury to the inhabitants of the state or not. . . . Such a statute, we do not doubt, it is beyond the power of a state to enact. To hold otherwise would be to ignore one of the leading objects which the Constitution of the United States was designed to secure.' p. 473, L. ed. 531.

It will be perceived that the act was an absolute prohibition operative during eight months of each year. It was an act continuous in its force; provided for no inspection; and was predicated on the assumption that the state had the right to exclude for two thirds of each year the introduction of all those kinds of cattle, sick or well, and whether likely to distribute disease or not.

In the case before us the statute makes no absolute prohibition of the introduction of sheep, but authorizes the governor to investigate the condition of sheep in any locality, and, if found to be subject to the scab or any epidemic disease liable to be communicated to other sheep, to make such restriction on their introduction into the state as shall seem to him, after conference with the state sheep inspector, to be necessary. The Executive acted on the authority thus conferred, and, after consultation with the state sheep inspector and examination of the matter, found that the scab was epidemic in certain localities in Utah and Nevada, and that if sheep from those localities were moved therefrom into Idaho they would spread infection and disease among the sheep of the state, and thereupon forbade the introduction of sheep from such localities for the space of sixty days. It will be perceived that this is not a continuous act, operating year after year irrespective of any examination as to the actual facts, but is one contemplating in every case investigation by the chief executive of the state before any order of restraint is issued. Whether such restraint shall be total or limited, and for what length of time, are matters to be determined by him upon full consideration of the condition of the sheep in the localities supposed to be affected. The statute was an act of the state of Idaho, contemplating solely the protection of its own sheep from the introduction among them of an infectious disease, and providing for only such restraints upon the introduction of sheep from other states as in the judgment of the state was absolutely necessary to prevent the spread of disease. The act therefore is very different from the one presented in Hannibal & St. J. R. Co. v. Husen, 95 U.S. 465, 24 L. ed. 527, and is fairly to be considered a purely quarantine act, and containing within its provisions nothing which is not reasonably appropriate therefor. There being no other Federal question in the case, the judgment of the Supreme Court of Idaho is affirmed.
