Their plan was to have someone of mixed blood, Plessy, violate the laws and see what would happen. He sat in the whites only first class section and told the conductor that he was 1/8 percent black. He was arrested immediately and was taken to the Louisiana District Court. The court ruled that the state had the contitutional power to control the railroad cars that stayed soley within the states' borders. The Separate Car Act was concluded to be constitutional. In 1893 the decision was appealed to the state and then again in 1896 to the U.S. Supreme Court.
