What characterizes a common law legal system?

A common law legal system is characterized by its reliance on case law and precedents established by judicial decisions. This means that the interpretation of laws can evolve over time through the rulings of judges in individual cases, creating a body of law that reflects past judgments and decisions. In common law systems, the outcomes of prior cases are used as references for deciding future cases, promoting consistency and predictability in legal rulings.

This system contrasts with legal systems that are based solely on statutory laws, where written laws enacted by a legislative body govern all decisions. Additionally, common law does not originate from a singular governing authority but rather from a dispersed system of courts that interpret and apply the law based on prior case decisions. Moreover, common law is not exclusive to Louisiana; it is widely used in many jurisdictions around the world, particularly in countries that were influenced by English law. Thus, the emphasis on case law and judicial precedents is the hallmark of a common law legal system.
