Homer Plessy argued that The Separate Car act violated his 13th and 14th amendment Rights. He said that his 13th amendment rights were violated because he was being forced into involuntary servitude by being forced to sit in a train car that he didn't wish to. HE said that his 14th Amendment rights were denied because the laws separating blacks and whites in public facilities like those of the Louisiana Railroad, made blacks inferior to whites because the quality of the black facilities was of much poorer quality than those of the whites.
