All the 50 states of the USA are separate and autonomous, having their own state constitutions, state courts and state governments. They keep hold of their plenary power to create laws covering almost everything not anticipated by the federal decree, federal constitution or international pacts sanctioned by the federal senate. The laws that were being framed are based on the common law of England, an exception being Louisiana.
