Seeking to improve sanitary conditions, the Louisiana legislature and the city of New Orleans had established a corporation charged with regulating the slaughterhouse industry. Members of the Butchers' Benevolent Association challenged the constitutionality of the corporation, claiming that it violated the Fourteenth Amendment. That amendment had been ratified in the aftermath of the American Civil War with the primary intention of protecting civil rights of millions of newly emancipated freedmen in the Southern United States, but the butchers argued that the amendment protected their right to "sustain their lives through labor."
