Hugo Black,
South Carolina v. Katzenbach/Concurrence Black…
“ Since that time neither the Fifteenth Amendment nor any other Amendment to the Constitution has given the slightest indication of a purpose to grant Congress the power to veto state laws either by itself or its agents. Nor does any provision in the Constitution endow the federal courts with power to participate with state legislative bodies in determining what state policies shall be enacted into law. The judicial power to invalidate a law in a case or controversy after the law has become effective is a long way from the power to prevent a State from passing a law. ”
