Which state is noted for not following the common law system?

Louisiana is noted for not following the common law system primarily due to its unique legal heritage, which is rooted in civil law traditions derived from French and Spanish colonial influences. Unlike most states in the United States that follow English common law, Louisiana’s legal system is based on a comprehensive set of written codes and statutes, which govern many areas of law, including civil, criminal, and commercial matters.

This civil law system places less emphasis on judicial decisions as sources of legal authority compared to common law systems, where case law and judicial precedents play a crucial role. In Louisiana, the Civil Code and other codified statutes take precedence, which shapes how legal issues are resolved. This distinct approach makes Louisiana's legal framework different from that of the other states listed, which all adhere to common law principles.
