In the early days of English history, the kings tried to centralize the English government and establish a court system. Judges, called justices or magistrates, traveled in circuits around the countryside deciding cases. Because there was no written law, judges often made decisions based on the customs and traditions of the people. Judges shared their decisions with other judges and made every effort to share the same law "in common" with everyone else throughout the country. This practice formed the basis of Common Law. This practice led to the doctoring of precedent
The unwritten law based on previous court decisions is known as "case law" or "common law." This legal principle derives from judicial rulings and precedents established in earlier cases, which guide the decisions in new cases with similar circumstances. Case law evolves over time as courts interpret statutes and constitutional provisions, providing a framework for understanding legal principles.
