The answer is the implied powers being used to enforce powers specifically defined in the constitution.
Implied powers are congress exercised powers which are not given explicitly by the constitution. While express powers are the powers which is given by the constitution.
Expressed powers are powers spcificaly given to Congress in the Constitution and Implied powers are given to the Congress in Article 1 section 8 of the Constitution at least that is what my history book says.
implied powers
Are powers given to the Congress that are general
These powers are referred to as implied powers, powers that are not explicitly granted to Congress in the U.S. Constitution. The opposite would be expressed powers.
They are implied in Article I, Section 1 of the Constitution
The commerce clause
Expressed: Powers given to Congress Implied: Not spelled out but given or "implied" Reserved: Not expressed in the Constitution and are granted to the states
Congress' powers are listed in Article one of the Constitution. Specific powers are enumerated in section eight. Congress has expressed powers that are written in the Constitution and implied powers that are not expressed.
Implied powers allow Congress to execute anything they see as necessary and proper, and it doesn't need to fall under the expressed powers of the Constitution.
Congressional powers not expressed are implied powers.
