The primary function of the judiciary is to interpret laws. When there is a dispute or disagreement about the meaning or application of a law, it is the role of the judiciary to interpret the law and make a decision based on that interpretation. The judiciary plays a critical role in ensuring that laws are applied fairly and consistently, and that the rights of individuals are protected. While the judiciary may also play a role in enforcing laws and maintaining law and order, its primary function is to interpret laws.
