Final answer:
An executive order is a clarification of congressional policy issued by the president with the full force of law, used to implement, interpret, or create policy within the scope of existing legislation.
Step-by-step explanation:
The type of law that is a clarification of congressional policy issued by the president and having the full force of the law is an executive order. Executive orders are directives from the president to administrators in the executive branch on how to implement legislation, and the courts treat them as equivalent to laws. These orders can significantly impact domestic policy and have historically resulted in dramatic events, such as the Emancipation Proclamation and the authorization of Japanese American internment during World War II. They can be used to enforce, interpret, and sometimes create policy within the boundaries of existing law. An executive order is a clarification of congressional policy issued by the president and has the full force of the law. While an executive order is not legislation passed by Congress, it is a directive from the President of the United States that carries the weight of law and is used to manage the operations of the federal government. Executive orders are a form of administrative law that allows the president to implement and enforce policies without the need for congressional approval.
