Congress does not have the power to grant titles of nobility, which prevents the establishment of a hereditary aristocracy. It cannot pass ex post facto laws, meaning it cannot retroactively make actions illegal. Additionally, Congress is prohibited from passing bills of attainder, which are laws that punish individuals without a trial. Lastly, Congress cannot regulate state functions or interfere with state sovereignty without proper constitutional authority.
The powers forbidden to the US Congress (and Federal Government in general) are listed in the US Constitution in a very simply fashion. Congress is permitted those powers specifically stated (and implied) in the Constitution. Powers not enumerated in the Constitution are reserved for the States, or for the People. So what is permitted to the Congress is listed, but not what is forbidden.
the amendment
Article I, Section 9 of the Constitution lists those powers.
The most important power in the constitution is the taxing and spending power given to Congress. Other important powers include the president's appointment and veto powers, Congress' foreign affairs and spending powers.
A. through the expressed, or clearly stated, powers, B. through the implied, powers ( powers deducted from the clearly stated powers), C. through the inherent powers, those possessed by all sovereign states.
It would be impossible to list "implied powers," as they're flexible and designed to fit circumstances as they arise. Implied Powers are those not enumerated by the Constitution (but not prohibited by it, either), but necessary to carry out government functions and responsibilities that arespecifically mentioned.
The enumerated powers are a list of items found in Article 1, Section 8 of the U.S constitution that sets forth an authoritative capacity of congress.
