What principle refers to the legal doctrine of letting the decision stand?

The principle that refers to the legal doctrine of letting the decision stand is known as stare decisis. This Latin term translates to "to stand by things decided," reflecting the practice in the judiciary of adhering to precedent. When courts apply stare decisis, they follow the legal principles established by previous cases to ensure consistency and predictability in the law. This doctrine plays a crucial role in maintaining the rule of law, as it encourages stability in judicial decisions and helps to shape the legal landscape over time.

Judicial review, while an important concept, specifically pertains to the power of courts to evaluate the constitutionality of legislative and executive actions, rather than the adherence to past decisions. Legal precedent refers to the outcomes of previous court cases that can influence future rulings, but it is not the principle of adhering to those decisions. Obiter dictum consists of remarks made by a judge in a legal opinion that are not essential to the decision and therefore do not have binding precedent, making it distinct from the doctrine of stare decisis, which mandates following binding decisions from higher courts.
