The judiciary plays a crucial role in upholding democratic principles by interpreting laws, protecting rights, and ensuring checks and balances within government. An independent judiciary safeguards the rule of law and acts as a protector of individual freedoms against potential government overreach. By reviewing legislation and executive actions, the judiciary ensures that all actions align with the constitution, protecting citizens from injustice. Moreover, through landmark rulings, the judiciary can influence social change by affirming rights and liberties, reinforcing the foundational values of democracy in society.
