Trump v. Anderson
The Supreme Court unanimously ruled that Colorado had no power to remove Donald Trump from its 2024 presidential primary ballot, holding that states cannot enforce the Constitution's insurrection-disqualification clause against federal candidates — that job belongs to Congress.
The decision immediately ended all state-level efforts to bar Trump from primary ballots, though it left unresolved the broader question of whether Congress could enact legislation to enforce the disqualification and triggered a sharp internal debate among the justices over how much the Court had decided.
“Nothing in the Constitution requires that we endure such chaos—arriving at any time or different times, up to and perhaps beyond the Inauguration.”
The Court explaining why allowing states to each decide a presidential candidate's Section 3 eligibility would be constitutionally unacceptable.
How it got here: Colorado voters sued in state court; a trial judge ruled against them; the Colorado Supreme Court reversed 4–3 and ordered Trump excluded from the primary ballot; Trump petitioned and the Supreme Court agreed to hear the case.
The Case in Depth
What happened
A group of Colorado voters filed a legal challenge arguing that Donald Trump, the former president seeking the 2024 Republican presidential nomination, was constitutionally disqualified from the ballot under Section 3 of the Fourteenth Amendment — a provision barring from office anyone who previously swore an oath to uphold the Constitution and then engaged in insurrection. The voters argued Trump's role in the events of January 6, 2021, when a crowd breached the U.S. Capitol as Congress certified the 2020 election results, met that standard. After a five-day trial, Colorado's Supreme Court agreed and ordered him excluded from the primary ballot.
The question before the Court
Can a state remove a presidential candidate from its primary ballot by declaring that the candidate engaged in insurrection under Section 3 of the Fourteenth Amendment?
The Court's answer
No — Colorado could not keep Trump off its primary ballot. The Court held that enforcing Section 3 of the Fourteenth Amendment against federal officeholders and candidates is the responsibility of Congress, not the individual states. Because nothing in the Constitution expressly delegates to states the power to disqualify federal candidates under Section 3, Colorado's order was unconstitutional regardless of the underlying facts about Trump's conduct on January 6.
The Court also stressed the national stakes: allowing states to make their own determinations about a presidential candidate's eligibility under Section 3 would produce a chaotic and inconsistent patchwork of results — different states applying different evidentiary standards and reaching different conclusions about the same candidate. The Constitution does not require that kind of disorder, especially in a presidential election where the candidate must represent all voters nationwide. All nine justices agreed on that bottom line, though they divided sharply on how much further the opinion needed to go in addressing how federal enforcement of Section 3 could work in the future.

Why it matters
No state can use the Fourteenth Amendment's insurrection clause to exclude a federal candidate from its ballot. Voters in every state retain the ability to cast ballots for any candidate not disqualified through a federal process. The ruling also means any future effort to invoke Section 3 against a presidential candidate would have to come from Congress, not state courts or election officials.
What changes now
The Court ordered the mandate to issue immediately, so Trump remained on the Colorado primary ballot and the ruling bound every other state as well. Because this is a final merits decision, no state may use Section 3 to exclude a federal candidate from its ballot going forward. Questions about how Congress might legislate to enforce Section 3, and whether any other federal mechanism could support a disqualification, remain open and were not resolved by the Court.
What this does not decide
The ruling does not decide whether Trump actually engaged in insurrection or whether he is disqualified from office under Section 3. It also does not decide whether Congress could pass legislation to enforce Section 3, or what procedures such legislation would need to follow — three justices argued the majority improperly foreclosed those questions by saying too much.
Concurrences and dissents
Concurrence in part — Justice Barrett
Justice Barrett joined the core parts of the per curiam holding that states lack power to enforce Section 3 against presidential candidates, and agreed that conclusion was fully sufficient to decide the case. She would have stopped there and not addressed whether congressional legislation is the only permissible vehicle for federal enforcement of Section 3. She urged all the justices to let the Court's unanimous outcome — rather than divisions over rationale — be the message to the public, especially given the politically charged moment.
Concurrence — Justice Sotomayor
Justices Sotomayor, Kagan, and Jackson agreed that Colorado could not remove Trump from the ballot, because permitting state-by-state enforcement of Section 3 in a presidential election would create a chaotic patchwork incompatible with federalism — and that conclusion alone resolved the case. They sharply objected that the majority then went further to address how federal enforcement of Section 3 must work, a question not before the Court. In their view, the majority's ruling — that disqualification can occur only through specific congressional legislation under Section 5 — was unsupported by the text and history of the Amendment and improperly foreclosed other potential federal enforcement avenues.
How the Court got there
The legal reasoning, step by step
- Section 3 of the Fourteenth Amendment does not operate automatically — it imposes a penalty on specific individuals, so someone must make a formal determination about whether it applies to a particular person before a disqualification takes effect. The Court reasoned that the Constitution assigns that responsibility to Congress, not to individual states.
- Section 5 of the Fourteenth Amendment gives Congress — not the states — the power to enforce the Amendment through legislation. Historical evidence reinforced this point: shortly after ratification, Congress passed the Enforcement Act of 1870 precisely because Section 3 itself provided no enforcement mechanism, and members of Congress at the time understood the provision needed implementing legislation to have practical effect.
- While states have broad authority over their own governance and may disqualify people from state offices under Section 3, federal officeholders and candidates are different. The Court applied a foundational principle: powers over federal officers must be specifically *delegated* to the states by the Constitution; states cannot treat such powers as reserved. Nothing in the Constitution — not Section 3, not Section 5, not the Elections Clause, not the Electors Clause — specifically grants states the power to enforce Section 3 against federal candidates.
- The structure of the Fourteenth Amendment itself cuts against state enforcement power. The Amendment as a whole restricts what states may do and expands what Congress may do. Reading this particular Amendment to silently grant states a new power to disqualify federal candidates would invert its fundamental design.
- Historical practice confirmed this reading: in the years immediately after ratification, states did disqualify people from their own state offices under Section 3, but there is essentially no historical tradition of states enforcing Section 3 against federal candidates — a stark contrast that the Court treated as strong evidence of a shared original understanding that states lacked that authority.
- Finally, state-by-state enforcement for the presidency would produce a constitutionally unacceptable patchwork: different states might apply different evidentiary standards, some might allow expedited civil challenges while others allow only criminal prosecution, and a single candidate could end up on the ballot in some states but not others based on the identical conduct. That disruption — which could nullify millions of votes and potentially extend past Inauguration Day — is something the Constitution simply does not require.
