same body. If this was the intention, why not leave it, in the first instance, to what is alleged to be the natural operation of the original clause, conferring a general power of taxation upon the Union? It is evident that this could not have been the intention, and that it will not bear a construction of the kind.
As to a supposition of repugnancy between the power of taxation in the States and in the Union, it cannot be supported in that sense which would be requisite to work an exclusion of the States. It is indeed possible that a tax might be laid on a particular article by a State which might render it inexpedient that thus a further tax should be laid on the same article by the Union; but it would not imply a constitutional inability to impose a further tax. The quantity of the imposition, the expediency or inexpediency of an increase on either side, would be mutually questions of prudence; but there would be involved no direct contradiction of power. The particular policy of the National and of the State systems of finance might now and then not exactly coincide, and might require reciprocal forbearances. It is not, however, a mere possibility of inconvenience in the exercise of powers, but an immediate constitutional repugnancy, that can by implication alienate and extinguish a preëxisting right of sovereignty.
The necessity of a concurrent jurisdiction in certain cases results from the division of the sovereign power; and the rule that all authorities, of which the States are not explicitly divested in favor of the Union, remain with them in full vigor, is not a theoretical consequence of that division, but is clearly admitted by the whole tenor of the instrument which contains the Articles of the proposed Constitution. We there find, that, notwithstanding the affirmative grants of general authorities, there has been the most pointed care in those cases where it was deemed improper that the like authorities
