What is a contested election? The legal challenge to a result, explained

A race is decided by a few hundred votes, lawyers descend, and the commentators start talking about a “contested election.” Historians and lawyers use that phrase for something narrower than a photo finish.

If you remember one thing, remember this: a “contested election” is a formal legal challenge to the outcome on specified grounds — not simply a close race. A close race that is not challenged is just a close race. A contested election is one in which a candidate has formally put the result in question, following a defined process with strict deadlines.

Why doesn’t “contested” mean close?

The National Conference of State Legislatures puts it plainly: a contested election “does not mean a highly competitive race; instead, it means a race in which a candidate contests the outcome on legal grounds.” A nail-biter settled by a recount is counted, certified, and not contested. A contest is a legal proceeding that a candidate deliberately initiates.

That distinction matters, because “the election was contested” is one of the most misused phrases in American politics. Almost every competitive race is “contested” in the colloquial sense; very few are contested in the legal one.

Who can contest, and on what grounds?

To bring a contest, a candidate generally must have been on the ballot and claim a right to the office — you cannot challenge an election you did not run in just because you dislike the result. The grounds must be legal, and the bar is high: the person contesting must show that errors, misconduct, or irregularities were serious enough to have changed the outcome. Courts and legislatures treat mere allegations of problems differently from proof that enough votes were in dispute to flip the seat.

Deadlines are short and strict. Miss the window, and the challenge is generally barred — the timeline usually cannot be reopened.

What is the House track — the Federal Contested Elections Act?

For seats in the U.S. House of Representatives, the vehicle is a specific federal law: the Federal Contested Elections Act, codified at 2 U.S.C. §§ 381–396. Under it:

• The losing candidate — the “contestant” — must file a notice of contest with the Clerk of the House within 30 days after the result is officially declared (2 U.S.C. § 382(a)), stating the grounds “with particularity” (§ 382(b)). A bona fide write-in candidate qualifies too, not just names printed on the ballot (§ 381(2)).
• The Member whose seat is challenged — the “contestee” — then gets 30 days after being served with the notice to answer (§ 383).
• The case goes to the Committee on House Administration, and ultimately the House itself decides who is entitled to the seat.

That last point comes straight from the Constitution: Article I, Section 5 says “each House shall be the Judge of the Elections, Returns and Qualifications of its own Members.” The Congress of the United States, acting as a body, is the judge of its own membership disputes — not a court. Importantly, this federal statute covers general and special elections; it does not govern primary elections.

What about the Senate, state, and local track?

The Federal Contested Elections Act applies only to House elections. For Senate seats and for state and local offices, contests run through state law and, for the Senate, the chamber’s own rules — and the Senate has no codified contested-election procedure like the House’s. As with so much else in U.S. elections, this varies from state to state: states define what counts as a contest, who can bring it, on what grounds, and by when. There is no single national contest procedure outside the House statute.

Why do lawsuits run alongside contests?

A candidate may also file a lawsuit in state or federal court — for example, seeking a court-ordered recount, to block certification, or to invalidate specified ballots. A lawsuit is distinct from a statutory contest: it is ordinary litigation, decided by a judge, under court rules and standards of proof, and it can proceed in parallel with (or before) any formal contest. Both are legal challenges to a result; they simply occur in different forums.

What is the presidential track?

In a presidential year, the states still canvass and certify first, and state courts and recounts still handle the raw votes. The federal step comes afterward, when Congress counts the electoral votes in early January (3 U.S.C. § 15). Members of Congress may object to a state’s electoral votes, but rejecting those votes requires both chambers of Congress to agree — a high bar that is rarely met. The congressional count follows the states’ certifications; it is not a federal body overturning the popular vote. Our explainer on who certifies election results covers this sequencing.

Can a contest change the outcome?

Yes in principle, but rarely in practice. The burden is on the challenger, the legal standard demands that the disputed votes be enough to change the result, and deadlines are unforgiving. Most challenges are dismissed or fail. And a seat is not left empty while a contest proceeds: the certified winner is generally sworn in at the start of Congress — the certificate of election is treated as prima facie evidence of the result — while the House (or the relevant body) resolves the contest. Disputed results that genuinely change certified outcomes are the exception, not the rule.

Where do you get official information?

• Your state or local election office — the authority on your state’s contest and recount procedures and deadlines. The EAC’s state lookup points to each one: eac.gov/vote.
• vote.gov — the official federal voting-information site, in place since 2016 and administered by the General Services Administration until the EAC assumed management of the site in 2025; the EAC now operates and hosts it — state-by-state paths.
• The network’s Voting & Elections topic page collects these explainers, alongside How Midterm Elections Work, How to Register to Vote in the U.S., What Happens After Election Day, What Is a Provisional Ballot?, and Who Certifies Election Results?.

What is the bottom line?

A contested election is a formal legal challenge to a result, not a close race. For the House, the Federal Contested Elections Act gives the losing candidate 30 days from the declaration to file a notice with the Clerk, with the Committee on House Administration and ultimately the House deciding. The Senate and state/local races follow state procedures; presidential outcomes are decided for federal purposes by Congress’s count of the electoral votes after the states have certified. Contests can overturn a result, but the burden is high, the deadlines strict, and reversals rare. For your own state’s rules, go to your state or local election office or vote.gov.
