The judiciary plays a critical role in protecting democracy by upholding the rule of law and ensuring that laws are applied fairly and justly. It serves as a check on the other branches of government, safeguarding citizens' rights and liberties from potential abuses. Judicial review allows courts to evaluate the constitutionality of laws and government actions, providing mechanisms for accountability. By interpreting laws and resolving disputes, the judiciary promotes fairness and equity within the political system, ultimately reinforcing democratic principles and contributing to a healthier society.
