A Brazilian Supreme Court judge has opened an inquiry into Elon Musk after the multi-billionaire said he would reactivate accounts on the social media platform X, formerly Twitter, that the judge had ordered to be blocked.
Musk posted on the platform that the restrictions had been lifted because the court order was unconstitutional.
He also called for Justice Alexandre de Moraes to resign or be impeached.
If X fails to comply with the order, it will be fined nearly US $20,000 per day.
In his decision, Justice Moraes wrote that Musk had launched a disinformation campaign against the Supreme Court.
The platform’s Global Government Affairs team said the company was not allowed to say which accounts were affected.
