The gentleman has found no case, he can find none, to support his own opinions by New England authority. New England has studied the Constitution in other schools, and under other teachers. She looks upon it with other regards, and deems more highly and reverently both of its just authority and its utility and excellence. The history of her legislative proceedings may be traced. The ephemeral effusions of temporary bodies, called together by the excitement of the occasion, may be hunted up; they have been hunted up. The opinions and votes of her public men, in and out of Congress, may be explored. It will all be in vain. The Carolina doctrine can derive from her neither countenance nor support. She rejects it now; she always did reject it; and till she loses her senses, she always will reject it. The honorable member has referred to expressions on the subject of the embargo law, made in this place, by an honorable and venerable gentleman, now favoring us with his presence. [24] He quotes that distinguished Senator as saying, that, in his judgment, the embargo law was unconstitutional, and that therefore, in his opinion, the people were not bound to obey it. That, Sir, is perfectly constitutional language. An unconstitutional law is not binding; _but then it does not rest with a resolution or a law of a State legislature to decide whether an act of Congress be or be not constitutional_. An unconstitutional act of Congress would not bind the people of this District, although they have no legislature to interfere in their behalf; and, on the other hand, a constitutional law of Congress does bind the citizens of every State, although all their legislatures should undertake to annul it by act or resolution. The venerable Connecticut Senator is a constitutional lawyer, of sound principles and enlarged knowledge; a statesman practised and experienced, bred in the company of Washington, and holding just views upon the nature of our governments. He believed the embargo unconstitutional, and so did others; but what then? Who did he suppose was to decide that question? The State legislatures? Certainly not. No such sentiment ever escaped his lips.
