Judicial review plays a pivotal role in the checks and balances system of government by allowing courts to evaluate the constitutionality of federal and state laws. This power ensures that the legislative and executive branches do not exceed their authority or infringe upon individual rights. Through judicial review, courts can invalidate laws or executive actions that conflict with the Constitution, thereby protecting civil liberties and reinforcing the rule of law. The implications of this practice extend to the interpretation of rights, influencing both public policy and the boundaries of governmental power.
