A. “Privileges or Immunities” Clause: The “Privileges or Immunities” Clause of the Fourteenth Amendment comes at the beginning of the second sentence of Section I: “No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States. … ” At least some of the members of Congress who participated in the drafting of the Fourteenth Amendment expected and hoped that this Clause would constitute a substantial restraint on state government action against individuals. See Tribe, p. 550.
a. Facts of Slaughterhouse Cases: The Slaughterhouse Cases arose when Louisiana passed a law giving a monopoly on New Orleans-area slaughterhouses to a particular company. Butchers not included in the monopoly claimed that the statute deprived them of the opportunity to practice their trade, and thereby violated the Thirteenth and Fourteenth Amendments. The plaintiffs’ most serious argument was that the statute was a denial of the privileges or immunities of Louisiana citizenship, including the right to practice one’s calling.
b. Argument rejected: But the Supreme Court rejected all of the plaintiffs’ contentions, including the privileges or immunities argument. The Court observed that the first sentence of the Fourteenth Amendment distinguishes between U.S. citizenship (for which one need merely be born or naturalized in the United States) and state citizenship (for which residence is required). “Fundamental” civil rights, including the right to practice one’s calling, were the domain of the states, not the federal government. Therefore, the plaintiffs should look to Louisiana law for protection; if there was no protection under Louisiana law (as apparently there was not), the plaintiffs were out of luck, since the Privileges or Immunities Clause added nothing to their rights in this area.
