The authority to amend the Constitution of the United States is derived from Article V of the Constitution. After Congress proposes an amendment, the Archivist of the United States, who heads the National Archives and Records Administration (NARA), is charged with responsibility for administering the ratification process under the provisions of 1 U.S.C. 106b. The Archivist has delegated many of the ministerial duties associated with this function to the Director of the Federal Register. Neither Article V of the Constitution nor section 106b describe the ratification process in detail. The Archivist and the Director of the Federal Register follow procedures and customs established by the Secretary of State, who performed these duties until 1950, and the Administrator of General Services, who served in this capacity until NARA assumed responsibility as an independent agency in 1985.
