The decision from a court whose justices were all appointed by Democratic governors marks the first time in history that Section 3 of the 14th Amendment has been used to disqualify a presidential candidate.
“A majority of the court holds that Trump is disqualified from holding the office of president under Section 3 of the 14th Amendment,” the court wrote in its 4-3 decision.
The court stayed its decision until Jan. 4, or until the U.S. Supreme Court rules on the case. Colorado officials say the issue must be settled by Jan. 5, the deadline for the state to print its presidential primary ballots.
Trump’s attorneys had promised to appeal any disqualification immediately to the nation’s highest court, which has the final say about constitutional matters.
Trump didn’t mention the decision during a rally Tuesday evening in Waterloo, Iowa, but his campaign sent out a fundraising email citing what it called a “tyrannical ruling.”
Republican National Committee chairwoman Ronna McDaniel labeled the decision “Election interference” and said the RNC’s legal team intends to help Trump fight the ruling.
Dozens of lawsuits have been filed nationally to disqualify Trump under Section 3, which was designed to keep former Confederates from returning to government after the Civil War. It bars from office anyone who swore an oath to “support” the Constitution and then “engaged in insurrection or rebellion” against it, and has been used only a handful of times since the decade after the Civil War.
The Colorado case is the first where the plaintiffs succeeded. After a weeklong hearing in November, District Judge Sarah B. Wallace found that Trump indeed had “engaged in insurrection” by inciting the Jan. 6 attack on the Capitol, and her ruling that kept him on the ballot was a fairly technical one.

The state’s highest court didn’t agree, siding with attorneys for six Colorado Republican and unaffiliated voters who argued that it was nonsensical to imagine that the framers of the amendment, fearful of former confederates returning to power, would bar them from low-level offices but not the highest one in the land.
The left-leaning group that brought the Colorado case, Citizens for Responsibility and Ethics in Washington, hailed the ruling.

That met skepticism from several of the justices.
In the ruling issued Tuesday, the court’s majority dismissed the arguments that Trump wasn’t responsible for his supporters’ violent attack, which was intended to halt Congress’ certification of the presidential vote: “President Trump then gave a speech in which he literally exhorted his supporters to fight at the Capitol,” they wrote.
“Our government cannot deprive someone of the right to hold public office without due process of law,” Samour wrote in his dissent. “Even if we are convinced that a candidate committed horrible acts in the past — dare I say, engaged in insurrection — there must be procedural due process before we can declare that individual disqualified from holding public office.”
The Colorado ruling stands in contrast with the Minnesota Supreme Court, which last month decided that the state party can put anyone it wants on its primary ballot. It dismissed a Section 3 lawsuit but said the plaintiffs could try again during the general election.
Both groups are financed by liberal donors who also support President Joe Biden. Trump has blamed the president for the lawsuits against him, even though Biden has no role in them, saying his rival is “defacing the constitution” to try to end his campaign.
“Four partisan Democrat operatives on the Colorado Supreme Court think they get to decide for all Coloradans and Americans the next presidential election,” House Republican Conference Chair Elise Stefanik said in a statement.
