The significance of executive power in shaping policy lies in its ability to direct government action without the need for legislative approval. This power encompasses executive orders, proclamations, and decisions that can swiftly address critical issues. However, the use of executive power raises questions about democracy and accountability, as it may bypass checks and balances inherent in the legislative process. The scope and limits of executive authority affect the policy landscape, as subsequent administrations may alter or revoke previous actions, creating an ongoing cycle of political change.
