The significance of judicial review lies in its power to uphold the rule of law by allowing courts to assess the constitutionality of legislative and executive actions. This mechanism serves as a check on government power, ensuring that laws and policies conform to constitutional principles. Judicial review protects individual rights and maintains the balance of power among branches of government. By interpreting constitutional provisions, courts can invalidate legislation that violates fundamental rights, reinforcing democracy and the protection of citizens’ freedoms.
