Madison's judgment is clearer. He was chairman of a committee of the Virginia Legislature, which issued a book-length "Report on the Resolutions of 1798", published in 1800 after they had been decried by several states. This asserted that the state did not claim legal force. "The declarations in such cases are expressions of opinion, unaccompanied by other effect than what they may produce upon opinion, by exciting reflection. The opinions of the judiciary, on the other hand, are carried into immediate effect by force." If the states collectively agreed in their declarations, there were several methods by which it might prevail, from persuading Congress to repeal the unconstitutional law, to calling a constitutional convention, as two-thirds of the states may. When, at the time of the nullification crisis, he was presented with the Kentucky resolutions of 1799, he argued that the resolutions themselves were not Jefferson's words, and that Jefferson meant this not as a constitutional, but as a revolutionary right.
