Judicial reviews serve the purpose of ensuring that legislative actions comply with the constitution. Through this process, courts evaluate the legality and constitutionality of laws, providing a check on legislative power. Judicial reviews help to protect individual rights and maintain the rule of law, preventing unlawful or overreaching legislation from taking effect. This judicial oversight is crucial for preserving a healthy democratic system, reinforcing accountability among lawmakers. Ultimately, judicial reviews contribute to the stability and integrity of governance by aligning laws with constitutional principles and protecting citizens' rights.
