Judicial review is a crucial mechanism that impacts the balance of power in government by allowing courts to assess the constitutionality of legislative and executive actions. This process ensures that laws and policies adhere to constitutional principles, serving as a check on governmental authority. Judicial review can protect individual rights and maintain the rule of law, safeguarding against potential government overreach. However, the authority of the judiciary can raise questions regarding the separation of powers, especially when courts challenge decisions made by elected officials. In this manner, judicial review is essential for sustaining democratic governance and protecting civil liberties.
