Tom C. Clark,
Kinsella v. United States — Opinion of the Court
“ Nor do we believe that due process considerations bring about an expansion of Clause 14 through the operation of the Necessary and Proper Clause. If the exercise of the power is valid it is because it is granted in Clause 14, not because of the Necessary and Proper Clause. The latter clause is not itself a grant of power, but a caveat that the Congress possesses all the means necessary to carry out the specifically granted 'foregoing' powers of § 8 'and all other Powers vested by this Constitution. ”
