Instead, it is Congress that has long given effect to Section 3 with respect to would-be or existing federal officeholders. Shortly after ratification of the Amendment, Congress enacted the Enforcement Act of 1870. That Act authorized federal district attorneys to bring civil actions in federal court to remove anyone holding nonlegislative office—federal or state—in violation of Section 3, and made holding or attempting to hold office in violation of Section 3 a federal crime. §§14, 15, 16 Stat. 143–144 (repealed, 35 Stat. 1153–1154, 62 Stat. 992–993). In the years following ratification, the House and Senate exercised their unique powers under Article I to adjudicate challenges contending that certain prospective or sitting Members could not take or retain their seats due to Section 3. See Art. I, §5, cls. 1, 2; 1 A. Hinds, Precedents of the House of Representatives §§459–463, pp. 470–486 (1907). And the Confiscation Act of 1862, which predated Section 3, effectively provided an additional procedure for enforcing disqualification. That law made engaging in insurrection or rebellion, among other acts, a federal crime punishable by disqualification from holding office under the United States. See §§2, 3, 12 Stat. 590. A successor to those provisions remains on the books today. See 18 U. S. C. §2383.
Moreover, permitting state enforcement of Section 3 against federal officeholders and candidates would raise serious questions about the scope of that power. Section 5 limits congressional legislation enforcing Section 3, because Section 5 is strictly “remedial.” City of Boerne, 521 U. S., at 520. To comply with that limitation, Congress “must tailor its legislative scheme to remedying or preventing” the specific conduct the relevant provision prohibits. Florida Prepaid Postsecondary Ed.
