How the doctrine of precedent operates with stare decidendi?

The doctrine of precedent operates through the principle of stare decisis, which means "to stand by things decided." This principle requires courts to follow the legal precedents established by higher courts in the same jurisdiction when making decisions in similar cases. By adhering to stare decisis, the law promotes consistency and predictability, ensuring that similar cases are treated alike unless there is a compelling reason to overturn or distinguish the precedent. This mechanism helps maintain stability in the legal system while allowing for gradual evolution of the law through carefully considered exceptions.
