“The Slaughterhouse Cases, resolved by the U.S. Supreme Court in 1873, ruled that a citizen's "privileges and immunities," as protected by the Constitution's Fourteenth Amendment against the states, were limited to those spelled out in the Constitution and did not include many rights given by the individual states.”
“The issue was that they argued the monopoly created involuntary servitude in violation of the Thirteenth Amendment, and abridged privileges or immunities, denied equal protection of the laws, and deprived them of liberty and property without due process of law in violation of the Fourteenth Amendment.”
“The court held that the monopoly violated neither the Thirteenth or Fourteenth Amendments, reasoning that these amendments were passed with the narrow intent to grant full equality to former slaves. Thus, to the Court, the Fourteenth Amendment only banned the states from depriving blacks of equal rights; it did not guarantee that all citizens, regardless of race, should receive equal economic privileges by the state.” So basically “The Slaughterhouse Cases, resolved by the U.S. Supreme Court in 1873, ruled that a citizen's "privileges and immunities," as protected by the Constitution's Fourteenth Amendment against the states, were limited to those spelled out in the Constitution and did not include many rights given by the individual states.”
