Between the years 527 and 565, Justinian I was the emperor of ancient Rome. His revision of Roman law in the “Corpus Juris Civilis” (“Body of Civil Law”), which continues to serve as the foundation for contemporary civil law systems around the world, is one of his lasting contributions.
Civil law has several different definitions in the US. In the majority of the U.S., the terms “common law” and “judge-made law,” which depend on earlier court rulings to decide case outcomes, are interchangeable terms for civil law. The guiding principle is “Stare Decisis,” which states that a lawsuit’s conclusion is determined by the results of earlier, comparable cases.
