The main function of the judiciary is to interpret the laws of the land. This means that the judiciary is responsible for ensuring that the laws are properly understood and applied in cases brought before them. The judiciary's interpretation of the law is based on legal principles and precedents established over time, as well as the specific facts of the case at hand.
In addition to interpreting the law, the judiciary also has the responsibility of applying the law to specific cases and ensuring that justice is served. This includes protecting the rights and interests of all individuals, including accused persons, and ensuring that the legal process is fair and impartial.
While the judiciary does not enact laws, its interpretation and application of the law can have a significant impact on how laws are understood and implemented. Additionally, the judiciary serves as a check on the power of the executive branch by ensuring that its actions are legal and constitutional.
