Case law

Case law is the collection of past legal decisions written by courts and similar tribunals in the course of deciding cases, in which the law was analyzed using these cases to resolve ambiguities for deciding current cases. These past decisions are called "case law", or precedent. Stare decisis—a Latin phrase meaning “let the decision stand”—is the principle by which judges are bound to such past decisions. These judicial interpretations are distinguished from statutory law, which are codes enacted by legislative bodies, and regulatory law, which are established by executive agencies based on statutes. In some jurisdictions, case law can be applied to ongoing adjudication; for example, criminal proceedings or family law.
