Brazil’s Supreme Court on Monday upheld a decision to ban Elon Musk’s X nationwide, after the platform formerly known as Twitter refused to comply with orders by the country’s top judge.

Why it matters: The unanimous ruling by the five justices comes as Musk accuses Brazil’s top judge of acting as a “dictator” for suspending X in Latin America’s largest nation over misinformation concerns and for failing to appoint a legal representative for the social media platform in the country.

• Musk claims Justice Alexandre de Moraes is “destroying” free speech “for political purposes,” while X accused the judge of “censorship” when it announced the immediate closure of its Brazil offices last month as it refused to comply with the judge’s order.

Driving the news: Moraes warned Musk he would suspend X in Brazil if the company didn’t comply with his order by Thursday evening and the ban went into effect Saturday morning, but the judge asked the five-member Supreme Court panel to review his decision.
