In the 1939 case of Coleman v. Miller, the Supreme Court ruled that Congress has the final authority to determine whether, by lapse of time, a proposed constitutional amendment has lost its vitality before being ratified by enough states, and whether state ratifications are effective in light of attempts at subsequent withdrawal. The Court stated: "We think that, in accordance with this historic precedent, the question of the efficacy of ratifications by state legislatures, in the light of previous rejection or attempted withdrawal, should be regarded as a political question pertaining to the political departments, with the ultimate authority in the Congress in the exercise of its control over the promulgation of the adoption of the amendment."Coleman v. Miller, 307 U.S. 433, at 450
