What does the principle of stare decisis require courts to do?

The principle of stare decisis requires courts to abide by earlier decisions made in previous cases. This doctrine promotes consistency and predictability in the law, ensuring that similar cases are approached in a similar manner. When courts follow the rulings of past cases, they maintain stability in legal interpretations and uphold the rule of law, which is essential for fostering trust in the judicial system.

Stare decisis encourages judges to look at prior decisions as a foundation for their rulings, allowing for the evolution of legal precedents while still respecting established rulings. This principle helps to limit arbitrary decision-making and provides a reliable framework for those engaging with the legal system.
