The principle, central to legal systems derived from common law, dictates that courts should adhere to precedents set in prior decisions. This promotes consistency and predictability in the application of law. For example, if a Supreme Court case establishes a specific interpretation of a constitutional right, lower courts are bound to follow that interpretation in subsequent cases involving similar issues.
Adherence to established precedents offers stability and fairness within the legal framework. It allows individuals and organizations to understand their rights and obligations with greater clarity, as the likely outcome of litigation becomes more foreseeable. The historical development of this principle reflects a desire to avoid arbitrary or capricious rulings, fostering public trust in the judicial process and providing a framework for incremental legal development.
