Final answer:
The 'necessary and proper clause' actually expands Congress's powers rather than limiting them, allowing Congress to pass laws needed to carry out the enumerated powers, debunking the assertion that it limits national government power.
Step-by-step explanation:
The necessity and proper clause, often referred to as the 'elastic clause,' is found in Article I, Section 8 of the United States Constitution. This clause gives Congress the authority to make all laws which shall be necessary and proper for carrying into execution the enumerated powers and all other powers vested by the Constitution in the government of the United States.
Contrary to limiting the power of the national government, it has actually allowed Congress to exercise powers not explicitly listed in the Constitution, therefore expanding its abilities and reach. Hence, the statement 'The necessary and proper clause has had the effect of limiting the power of the national government' is False.
