What does the term "stare decisis" signify in the legal system?

The term "stare decisis" signifies that previous case rulings should influence current cases. This legal principle is foundational to the common law system, which emphasizes consistency and predictability in legal decisions. By adhering to established precedents, courts ensure that similar cases are treated alike, thereby promoting fairness and stability in the law. This principle not only guides judges in their decisions but also helps litigants understand how the law is likely to be applied to their situations.

Without the doctrine of stare decisis, the legal system would lack coherence, as courts could reach varying conclusions on similar facts, leading to unpredictability and potential injustice. Thus, the emphasis on honoring previous rulings plays a crucial role in maintaining the rule of law and ensuring that legal interpretations are grounded in established judicial outcomes.
