The judiciary plays a critical role in upholding democratic principles by interpreting laws, protecting constitutional rights, and ensuring justice. Courts act as a check on legislative and executive powers, safeguarding against abuse and maintaining the rule of law. By adjudicating disputes and reviewing regulations, the judiciary helps reinforce the separation of powers and protects individual rights against government overreach. A strong, independent judiciary is essential for fostering public trust in governance and ensuring that democratic values are upheld in legal processes.
