The role of the judiciary in a democratic system is to interpret laws, resolve disputes, and uphold justice in accordance with the Constitution. It acts as a critical check on the powers of the legislative and executive branches, safeguarding individual rights and ensuring the rule of law. An independent judiciary helps maintain public trust in the legal system by ensuring that laws are applied fairly and impartially. Additionally, it can address issues of constitutional validity, protecting citizens from abuses of power by state authorities.
