An executive order is a directive issued by the head of state or government that manages the operations of a nation's federal administration. While the structure and authority of executive orders vary by country, they generally allow leaders to direct government agencies, implement policies, or respond to emergencies without new legislation. In many systems, the legality of such orders is subject to constitutional or legislative limits and judicial oversight. The term is most prominently associated with presidential systems such as that of the United States, where executive orders carry legal weight within the president's administration.
In the United States, an executive order is a directive by the president of the United States that manages operations of the federal government. Executive orders are only binding on the federal government's executive branch. The legal or constitutional basis for executive orders has multiple sources. Article Two of the United States Constitution gives presidents broad executive and enforcement authority to use their discretion to determine how to enforce the law or to otherwise manage the resources and staff of the federal government's executive branch. The delegation of discretionary power to make such orders is required to be supported by either an expressed or implied congressional law, or the constitution itself. The vast majority of executive orders are proposed by federal agencies before being issued by the president.
