CONSTITUTIONAL LAW - VALIDITY OF STATE OCCUPATION TAX ON CONTRACTORS WITH THE FEDERAL GOVERNMENT

The increasing burden of both federal and state taxation during the past decade has multiplied the attempts by some of those affected to establish, in the courts, immunity from certain taxes. The limitations of the power of the governments to tax have, then, special significance for one who seeks, in that fashion, to challenge the imposition of a tax on himself. Two cases recently decided by the Supreme Court involved one of those limitations-that which denies to the states the power to enforce a tax which impedes the exercise of the powers of the federal government.
