The principle of judicial review refers to the power of the judiciary, particularly the higher courts such as the Supreme Court or High Courts, to examine the constitutionality of legislative enactments and executive actions. Through this power, the courts can invalidate laws, policies, or actions that violate the Constitution.
Judicial review acts as a check and balance on the legislature and executive, ensuring that their powers are exercised within constitutional limits.
It protects fundamental rights by striking down laws that infringe upon these rights.
The principle upholds the supremacy of the Constitution by ensuring that all laws conform to constitutional provisions.
Judicial review also maintains the rule of law by preventing arbitrary use of power.
Thus, judicial review safeguards democracy by ensuring that the government acts in accordance with the Constitution.
