Which legal concept means "to stand by things decided"?

The concept that means "to stand by things decided" is known as stare decisis. This doctrine emphasizes the importance of following established legal precedents in decision-making. It serves to promote stability and predictability in the law by ensuring that similar cases are decided in a consistent manner. Courts rely on previous rulings to guide their judgments on current cases, which helps to maintain the integrity of the legal system and fosters trust among the public in judicial outcomes.

This principle is foundational in common law systems, particularly in the United States, as it reinforces the idea that once a legal principle has been settled, it should not be disregarded lightly. By adhering to precedents, courts acknowledge the wisdom of prior judgments and allow the law to evolve gradually through judicial interpretation rather than abrupt changes.
