Donald Trump won an important victory today as the US Supreme Court overturned a court decision which barred the former president from the Colorado ballot based on a constitutional provision related to sedition for inciting and supporting the January 6, 2021 attack on the Capitol.

The judges unanimously overturned the previous ruling of December 19 of the Colorado Supreme Court which excluded Trump from the state’s Republican primary ballot on Tuesday.

The justices ruled a day before her primary “Super Tuesday” that states cannot invoke a post-Civil War constitutional provision to prevent presidential candidates from being on the ballot. That power rests with Congress, the court wrote in an unsigned ruling, the Associated Press reports.

The result ends efforts to block Trump from the primaries in Colorado, Illinois, Maine and elsewhere.

Trump’s case was the first before the Supreme Court which dealt with a provision of the 14th Amendment enacted after the Civil War to prevent former officials “engaged in rebellion” from holding office again.
