The judicial review process is a fundamental mechanism through which courts evaluate the constitutionality of legislative and executive actions. Serving as a critical check on government power, this process empowers the judiciary to invalidate laws or policies that contravene the principles enshrined in the Constitution. Judicial review helps maintain the balance of power among branches of government, fostering adherence to constitutional mandates. Through landmark rulings, the judiciary sets precedents that guide future interpretations of law, ensuring that individual rights and liberties are preserved against potential government overreach.
