Unseated members of the United States Congress
Members of the United States Congress who were denied their seat after an election
Both houses of the United States Congress have refused to seat new members based on Article I, Section 5 of the United States Constitution which states that:
"Each House shall be the judge of the elections, returns and qualifications of its own members, and a majority of each shall constitute a quorum to do business; but a smaller number may adjourn from day to day, and may be authorized to compel the attendance of absent members, in such manner, and under such penalties as each House may provide."
This had been interpreted that members of the House of Representatives and of the Senate could refuse to recognize the election or appointment of a new representative or senator for any reason, often political heterodoxy or criminal record.
However, the U.S. Supreme Court, in Powell v. McCormack (1969), limited the powers of the Congress to refuse to seat an elected member to when the individual does not meet the specific constitutional requirements of age, citizenship or residency. From the decision by Chief Justice Earl Warren: "Therefore, we hold that, since Adam Clayton Powell Jr., was duly elected by the voters of the 18th Congressional District of New York and was not ineligible to serve under any provision of the Constitution, the House was without power to exclude him from its membership."
The Federal Contested Elections Act of 1969 currently lays out the procedures by which each House determines contested elections.

On November 3, 1868, John Willis Menard, a Republican Creole of color, won a special election in Louisiana's 2nd congressional district to fill the seat of James Mann who died in office. Menard's challenger, Democrat Caleb S. Hunt, contested the election and appealed to the House that he be seated instead of Menard. In February 1869, the House suspended its rules to consider which man to seat, but ultimately could not reach a resolution and left the seat vacant for the remainder of Mann's term.
From 1869 to 1900, the House of Representatives refused to seat over 30 Southern Democratic candidates declared the winner by their states. In some cases they weren't seated because the House Elections Committee concluded that fraud, violence, or intimidation had been used against black voters, or, in some cases, that the election statutes of the states themselves were unconstitutional.

Why this record matters
The subject matters to the history & society register because the source frames it as members of the United States Congress who were denied their seat after an election. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Jun 1, 2026. The linked authority identifier is Q7897434. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1969, 1868, 1900 and 1869.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
