Where do executive powers come from?
Drawn directly from the oath of office
In most democratic countries, executive powers are derived from the constitution and other laws. The constitution outlines the powers of the executive branch and provides limitations and checks on those powers. In the United States, for example, executive powers are outlined in Article II of the Constitution. In parliamentary systems, executive powers are held by the Prime Minister and Cabinet, who are accountable to Parliament.
Executive powers may also be delegated by the legislature through laws and statutes. For example, Congress in the United States may pass laws that grant the President certain powers. The President may also exercise some inherent powers that are not explicitly granted by law, such as the power to conduct foreign relations. Additionally, the judiciary may occasionally grant the executive branch powers through landmark rulings.
Ultimately, the source of executive powers varies depending on the country and the specific context. Regardless of the source, it is important for the executive branch to operate within the confines of the law and respect the separation of powers.
