Stare Decisis

Stare decisis is a legal principle that mandates courts to follow the precedents established in previous rulings when the same points arise in litigation. It ensures consistency and stability in the law by obliging judges to adhere to established legal doctrines.

The doctrine of stare decisis originated in the common law tradition, promoting the idea that previous judgments should inform and guide future decisions. Its roots can be traced back to early English jurisprudence, reflecting its foundational role in the development of the American legal system.

In modern law, stare decisis is crucial for maintaining a consistent application of statutes and legal precedents, allowing parties to have predictable outcomes in judicial proceedings. Courts often cite established cases to justify their decisions, thereby reinforcing the legal framework and ensuring that similar cases are resolved similarly.
