What importance has the original package doctrine today as a restraint on State legislation affecting interstate commerce? The answer is, very little, if any. State laws prohibiting the importation of intoxicating liquor, have since the passage of the Twenty-first Amendment consistently been upheld, even when imposing a burden on interstate commerce or discriminating against liquor imported from another State.[940] Indeed the Court has, without appealing to the Twenty-first Amendment, even gone so far as to uphold a statute requiring a permit for transportation of liquor through the enacting State.[941] In Whitfield _v._ Ohio,[942] moreover, the Court upheld a State law prohibiting the sale in open market of convict-made goods including sales of goods imported from other States and still in the original package. While the decision is based on the Hawes-Cooper Act of 1929,[943] which follows the pattern of the Webb-Kenyon Act, Justice Sutherland speaking for the Court, takes pains to disparage the "unbroken-package doctrine, as applied to interstate commerce, * * *, as more artificial than sound."[944] Indeed, earlier cases make it clear that the enforcement of State quarantine and inspection acts, otherwise constitutional, is not to be impeded by the doctrine in any way.[945] CURBS ON THE INTERSTATE MOVEMENT OF PERSONS Prior to the Civil War the slaveholding States, ever fearful of a slave uprising, adopted legislation meant to exclude from their borders free Negroes whether hailing from abroad or from sister States, and in 1823 a South Carolina Negro Seamen's Act embodying this objective was held void by Justice William Johnson, himself a South Carolinian, in a case arising in the Carolina circuit and involving a colored British sailor.[946] The basis of the ruling, which created tremendous uproar in Charleston,[947] was the commerce clause and certain treaties of the United States. There followed two rulings of Attorneys General, the earlier by Attorney General Wirt, denouncing such legislation as unconstitutional;[948] the latter by Attorney General Berrien, sustaining it;[949] and in City of New York _v._ Miln[950] the Court, speaking by Justice Barbour of Virginia, asserted, six years after Nat Turner's rebellion, the power of the States to exclude undesirables in sweeping terms, which in the Passenger Cases,[951] decided in 1840, a narrowly divided Court considerably qualified. Shortly after the Civil War the Court overturned a Nevada statute which sought to halt the further loss of population by a special tax on railroads on every passenger carried out of the State.[952] This time only two Justices invoked the commerce clause; the majority, speaking by Justice Miller held the measure to be an unconstitutional interference with a right of national citizenship--a holding today translatable, in the terminology of the Fourteenth Amendment, as an abridgment of a privilege or immunity of citizens of the United States.
