The US Supreme Court on Monday removed a potential hurdle to Donald Trump’s bid to recapture the White House, unanimously dismissing a state court ruling that could have barred him from the ballot for engaging in insurrection.

The high-stakes ruling in favor of the former president came on the eve of the Super Tuesday primaries that are expected to cement Trump’s march toward the Republican nomination to take on President Joe Biden in November.

It was the most consequential election case heard by the court since it halted the Florida vote recount in 2000 with Republican George W. Bush narrowly leading Democrat Al Gore.

The question before the nine justices was whether Trump was ineligible to appear on the Republican presidential primary ballot in Colorado because he engaged in an insurrection — the January 6, 2021 assault on the US Capitol by his supporters.

In a 9-0 decision, the conservative-dominated court said “the judgment of the Colorado Supreme Court… cannot stand,” meaning 77-year-old Trump can appear on the state’s primary ballot.

“All nine Members of the Court agree with that result,” the ruling said, though one conservative and the three liberal justices dissented on certain technical aspects.

Trump hailed the decision, declaring a “BIG WIN FOR AMERICA!!!” in a post on his Truth Social website.

The case stemmed from a ruling in December by the supreme court of Colorado, one of the 15 states and territories voting on Super Tuesday.

The state court, citing the 14th Amendment to the US Constitution, ruled that Trump should be kicked off the ballot because of his role in the January 6 attack on Congress, when a mob tried to halt certification of Biden’s 2020 election victory.

Section 3 of the 14th Amendment bars those who engaged in “insurrection or rebellion” after once pledging to support and defend the Constitution from holding public office — although Trump’s lawyers argued the rule does not apply to the presidency.

During two hours of arguments last month, both conservative and liberal justices on the US Supreme Court expressed concern about having individual states decide which candidates can be on the presidential ballot this November.
