Which state is noted for not having a common law legal system?

Louisiana is notable for not having a common law legal system because it operates under a civil law system derived from the French and Spanish legal traditions. This system is characterized by comprehensive codifications and written statutes rather than relying primarily on case law, as is common in common law jurisdictions. In Louisiana, the civil code plays a central role in legal proceedings, and judges play a less significant role in the development of law compared to their counterparts in common law states. In contrast, Texas, California, and New York all follow the common law system, where judicial decisions and precedents form the basis of law, reflecting a reliance on case law to interpret statutes and guide court decisions. This distinction makes Louisiana unique among U.S. states in terms of its legal framework.
