An expressed power, also known as an enumerated power, is a power specifically granted to a governmental branch or agency in a constitution. This means that the authority to exercise that power is clearly stated in the constitution, as opposed to being implied or assumed. In the United States, expressed powers are found in Article I, Section 8 of the Constitution, which lists the powers of Congress. Examples of expressed powers include the power to tax, the power to regulate commerce, and the power to declare war.
