Despite direct work between Bayh and Celler and drafts of language by legal experts, it took the mediation of Lewis Powell of the American Bar Association with Celler to arrive at the final formulation of S. J. Res. 1 on June 10. On June 30, 1965, it was approved by both House and Senate, and within eight months was ratified by the requisite three-quarters of state legislatures to become the 25th Amendment to the Constitution. In 1973 it would undergo its true test, when a vice president would resign in disgrace, and under threat of impeachment a president would also resign. The 25th Amendment passed that test with flying colors.
