The judiciary plays a crucial role in upholding constitutional rights by interpreting laws and ensuring that they align with the constitution. Courts, particularly Supreme Courts, serve as arbiters of justice, assessing cases that involve potential violations of individual rights. Through judicial review, the judiciary can invalidate laws or executive actions deemed unconstitutional, thereby maintaining the rule of law. Additionally, the judiciary provides a forum for citizens to challenge government actions, ensuring governmental accountability. This function is vital for safeguarding civil liberties and promoting justice within a legal framework, reinforcing the fundamental principles of democracy.
