The significance of constitutional checks on executive power lies in their role in preventing abuse and maintaining a balance among government branches. These checks establish mechanisms for accountability, ensuring that the executive adheres to the rule of law and does not overstep its authority. Provisions such as legislative approval of budgets, judicial review, and oversight committees serve to scrutinize executive actions. By limiting executive power, constitutional checks protect individual rights and promote democratic governance, fostering trust in governmental institutions and ensuring that power is derived from the consent of the governed.
