The Supreme Court and discrimination cases (Slaughterhouse Cases of 1873)
The Slaughterhouse Cases of 1873, dealt with a Louisiana law that gave one New Orleans company the exclusive right to livestock production in the city. Butchers and livestock producers who did not work for this company sued the state,they argued that were being deprived of equal protection under the law that was guaranteed in the 14th Amendment. The supreme court disagreed, they said that state's rights it's own affairs “was essential to the perfect working of our complex form of government.” The Court also did little to stop states from discriminating on the basis of race or gender, even though the Fourteenth Amendment guaranteed equal protection under the law. At the end it made the 14th amendment weaker and then 10th Amendment stronger
