Colorado’s Supreme Court has ruled that Donald Trump cannot run for president next year in the state, citing a constitutional insurrection clause.
The court ruled that Mr Trump was not an eligible candidate because he had engaged in an insurrection over the US Capitol riot nearly three years ago.
It does not stop Mr Trump running in the other states and his campaign says it will appeal to the US Supreme Court.
The ruling only mentions the state’s primary election on 5 March, when Republican voters will choose their preferred candidate for president. But it could affect the general election in Colorado next November.
It is the first ever use of Section 3 of the US Constitution’s 14th Amendment to disqualify a presidential candidate.
Tuesday’s decision – which has been placed on hold pending appeal until next month – only applies in Colorado. Similar attempts to kick Mr Trump off the ballot in New Hampshire, Minnesota and Michigan have failed.
The justices wrote in their ruling: “We do not reach these conclusions lightly. We are mindful of the magnitude and weight of the questions now before us.
“We are likewise mindful of our solemn duty to apply the law, without fear or favor, and without being swayed by public reaction to the decisions that the law mandates we reach.”
The decision reverses an earlier one from a Colorado judge, who ruled that the 14th Amendment’s insurrection ban did not apply to presidents because the section did not explicitly mention them.
