The judiciary plays a vital role in protecting civil liberties by interpreting laws and ensuring justice. Courts serve as guardians of individual rights, safeguarding against government overreach and potential abuses. Through judicial review, the judiciary can nullify unconstitutional laws and safeguard freedoms such as speech, religion, and assembly. The judiciary's independence is crucial for maintaining impartiality, allowing it to uphold the rule of law. Moreover, landmark cases often set precedents that can expand or limit civil liberties, influencing society's evolving understandings of justice and equity.
