The Supreme Court on Monday unanimously restored Donald Trump to 2024 presidential primary ballots, rejecting state attempts to ban the Republican former president over the Capitol riot.

The justices ruled a day before the Super Tuesday primaries that states cannot invoke a post-Civil War constitutional provision to keep presidential candidates from appearing on ballots. That power resides with Congress, the court wrote in an unsigned opinion.

Trump posted on his social media network shortly after the decision was released: “BIG WIN FOR AMERICA!!!”

The outcome ends efforts in Colorado, Illinois, Maine and elsewhere to kick Trump, the front-runner for his party’s nomination, off the ballot because of his attempts to undo his loss in the 2020 election to Democrat Joe Biden, culminating in the Jan. 6, 2021, attack on the Capitol.

The justices sidestepped the politically fraught issue of insurrection in their opinions Monday.

The court held that states may bar candidates from state office. “But States have no power under the Constitution to enforce Section 3 with respect to federal offices, especially the Presidency,” the court wrote.

While all nine justices agreed that Trump should be on the ballot, there was sharp disagreement from the three liberal members of the court and a milder disagreement from conservative Justice Amy Coney Barrett that their colleagues went too far in determining what Congress must do to disqualify someone from federal office.

Justices Sonia Sotomayor, Elena Kagan and Ketanji Brown Jackson said they agreed that allowing the Colorado decision to stand could create a “chaotic state by state patchwork” but said they disagreed with the majority’s finding a disqualification for insurrection can only happen when Congress enacts legislation. “Today, the majority goes beyond the necessities of this case to limit how Section 3 can bar an oathbreaking insurrectionist from becoming President,” the three justices wrote in a joint opinion.

It’s unclear whether the ruling leaves open the possibility that Congress could refuse to certify the election of Trump or any other presidential candidate it sees as having violated Section 3.

Derek Muller, a law professor at Notre Dame University, said “it seems no,” noting that the liberals complained that the majority ruling forecloses any other ways for Congress to enforce the provision. Rick Hasen, a law professor at the University of California-Los Angeles, wrote that it’s frustratingly unclear what the bounds might be on Congress.
