Which principle assures that similar cases are treated in a consistent manner?

The principle that assures consistent treatment of similar cases is known as "stare decisis." This legal doctrine requires that courts follow the precedents established by previous decisions in order to maintain stability and predictability in the law. Under stare decisis, when a court has made a ruling in a case, that ruling serves as a guiding principle for future cases that involve similar facts and legal questions. This ensures that similar cases receive similar treatment, promoting fairness and consistency within the legal system.

Judicature relates to the administration of justice or the system of courts itself, but does not specifically address the consistency in case treatment. Jurisdiction refers to the authority of a court to hear a particular case, which does not directly impact how similar cases are treated. Equity pertains to fairness and justice in the legal system, often in specific areas where the law may not provide adequate remedies, but it is not the principle that enforces the consistency of case law.
