By the eighth section of the first article, Congress has the power of exclusive legislation in all cases whatsoever within this District. In the case of Loughborough _v._ Blake, (5 Whea., 324,) the question arose, whether Congress has power to impose direct taxes on persons and property in this District. It was insisted, that though the grant of power was in its terms broad enough to include direct taxation, it must be limited by the principle, that taxation and representation are inseparable. It would not be easy to fix on any political truth, better established or more fully admitted in our country, than that taxation and representation must exist together. We went into the war of the Revolution to assert it, and it is incorporated as fundamental into all American Governments. But however true and important this maxim may be, it is not necessarily of universal application. It was for the people of the United States, who ordained the Constitution, to decide whether it should or should not be permitted to operate within this District. Their decision was embodied in the words of the Constitution; and as that contained no such exception as would permit the maxim to operate in this District, this court, interpreting that language, held that the exception did not exist. Again, the Constitution confers on Congress power to regulate commerce with foreign nations. Under this, Congress passed an act on the 22d of December, 1807, unlimited in duration, laying an embargo on all ships and vessels in the ports or within the limits and jurisdiction of the United States. No law of the United States ever pressed so severely upon particular States. Though the constitutionality of the law was contested with an earnestness and zeal proportioned to the ruinous effects which were felt from it, and though, as Mr. Chief Justice Marshall has said, (9 Wheat., 192,) "a want of acuteness in discovering objections to a measure to which they felt the most deep-rooted hostility will not be imputed to those who were arrayed in opposition to this," I am not aware that the fact that it prohibited the use of a particular species of property, belonging almost exclusively to citizens of a few States, and this indefinitely, was ever supposed to show that it was unconstitutional. Something much more stringent, as a ground of legal judgment, was relied on--that the power to regulate commerce did not include the power to annihilate commerce.
