The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 74 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“Quarantine laws belong to that class of state legislation which, whether passed with intent to regulate commerce or not, must be admitted to have that effect, and which are valid until displaced or contravened by some legislation of Congress. The matter is one in which the rules that should govern it may in .many respects be different in different localities, and for that reason be better understood and more wisely established by the local authorities. The practice which should control a quarantine station on the Mississippi River, a hundred miles from the sea, may be. widely and wisely different from that which is best. for. the harbor of New York.”
1 later decision quote this exact passagee.g. Leisy v. Hardin““Por, while it may be a police power in the sense that all provisions for the health, comfort, and security of the citizens are police regulations and an exercise of the police power, it has been said more than once in this court that, even where such powers are so exercised as to come within the domain of federal authority, as defined by the constitution, the latter must prevail.””
1 later decision quote this exact passage““No doubt they believed that the power to do this belonged to the states; or, if it ever occurred to any of its members that congress might do something in that way, they probably believed that what ought to be done could be better and more wisely done by the authorities of the states, who were familiar with the matter.””
