The Colorado Republican Party has appealed against the state’s supreme court decision to find former President Donald Trump ineligible for US presidency.

The appeal, lodged on Wednesday, is the potential first step to a showdown at the nation’s highest court over the meaning of a 155-year-old constitutional provision banning people who “engaged in insurrection” from office.
