Stare decisis, a fundamental principle in common law systems, plays a crucial role in maintaining consistency and stability within the legal framework. Firstly, stare decisis ensures that similar cases are treated in a consistent manner, promoting fairness and predictability within the judicial system. For instance, in criminal law, the principle of stare decisis ensures that similar cases with comparable facts are treated equally. Secondly, stare decisis encourages judicial efficiency by providing courts with precedents to follow when resolving disputes.For example, if a court did not follow the precedent set in a previous case and instead decided to create its own ruling, it could lead to a proliferation of conflicting decisions and legal uncertainty, making it difficult for citizens to understand and rely on the law in their daily lives.
