US Presidency
1856

It has not unfrequently happened that lawgivers, with undue estimation of the value of the law they give or in the view of imparting to it peculiar strength, make it perpetual in terms; but they can not thus bind the conscience, the judgment, and the will of those who may succeed them, invested with similar responsibilities and clothed with equal authority. More careful investigation may prove the law to be unsound in principle. Experience may show it to be imperfect in detail and impracticable in execution. And then both reason and right combine not merely to justify but to require its repeal. The Constitution, supreme, as it is, over all the departments of the Government legislative, executive, and judicial is open to amendment by its very terms; and Congress or the States may, in their discretion, propose amendment to it, solemn compact though it in truth is between the sovereign States of the Union. In the present instance a political enactment which had ceased to have legal power or authority of any kind was repealed.
