Explanation:
Necessary and Proper Clause
The Necessary and Proper clause of the U.S. Constitution provides Congress the power to fulfill its legal powers.
Also known as the "elastic clause," it was written into the Constitution in 1787.
The first Supreme Court case against the clause was in 1819 when Maryland objected to Alexander Hamilton's formation of a National Bank.
The Necessary and Proper clause has been used in cases about many things, including challenges about Obamacare, legalizing marijuana, and collective bargaining.
