The billionaire owner of social media platform X has defied a court order to block certain accounts
Elon Musk bought Twitter, now called X, in 2022.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.
Mr Musk posted on the platform that the restrictions had been lifted because the court order was unconstitutional.
In his decision, Justice Moraes wrote that Mr 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.
Mr Musk has since posted that "X will publish everything demanded by [Moraes] and how those requests violate Brazilian law".
The profiles are believed to have been linked to far-right movements which posted content related to riots on 8 January last year when thousands of supporters of Brazil's former President Jair Bolsonaro stormed the country's Congress, the Supreme Court and the presidential palace.
On Saturday, the former president posted a video of a meeting he had with Mr Musk in May 2022.
Brazil's communication minister Paulo Pimenta criticised Mr Musk, posting in capital letters that "Social networks are not a lawless land".
If X decides to disobey the order, the platform could be blocked temporarily according to Bruna Santos who is the global campaigns manager at non profit organisation Digital Action.
"Musk acted to provoke the Brazilian judiciary," she said.
