A Brazilian electoral judge has ordered Flávio Bolsonaro’s campaign to stop paying to push a video attacking President Lula. Meta, the US company behind Instagram and Facebook, was given three hours to comply.
Judge André Mendonça of Brazil’s electoral court barred Flávio Bolsonaro from paying to promote a video attacking Lula on Wednesday, 14 October. He gave Meta, the US company behind Instagram and Facebook, three hours to stop the paid promotion, 11 days before the runoff.
Correio Braziliense and Estadão Conteúdo reported that Brasil Pronto Pra Mais, Lula’s coalition with running mate Geraldo Alckmin, made the request. The video can stay online, but the campaign cannot pay to spread it.
What the Court Ordered Flávio Bolsonaro to Stop
The video began running on 11 October, Estadão Conteúdo said. Its caption, translated from Portuguese, says Lula “abandoned Brazil” and promises to “rescue the country”.
Mendonça said the irregularity lies in the paid boosting, Estadão Conteúdo reported. Paid boosting pushes a post to people who would not otherwise see it, which rules bar for attacks on an opponent.
He ordered the paid promotion of the video and its caption to end within three hours. He also barred any new paid ad with an identical caption, on any boost or provider, Terra and O Liberal reported.
The order reaches Meta, which has the same three hours to remove the boost from Instagram and Facebook. The video itself may remain online organically, meaning without payment to widen its reach.
The decision is that of a single judge, who sits on Brazil’s Supreme Federal Court as well as the electoral court. It has been submitted to the full electoral court, Terra and Correio Braziliense reported.
A Repeat of a First-Round Case
Estadão Conteúdo said a piece with the same caption was boosted irregularly during the first round. The campaign was fined 5,000 reais (about US$990) for paid negative propaganda.
Mendonça issued that fine on Monday, 5 October, Agência Brasil reported. Conversions in this article use the central bank’s reference rate for 14 October, 5.0441 reais per US$1.
He followed the electoral prosecutor-general’s office, which said the message used rejection of the rival to promote Flávio’s own candidacy. The defence, the agency said, argued the post was a mere political judgment, with criticism of Lula a small part of it.
A Crítica and Jornal do Brasil reported that on Sunday, 11 October, Mendonça applied the same rule to Lula’s side. He barred Lula’s campaign from new paid promotion of ads saying Flávio opposes ending the six-day 6×1 work week.
What Brazilian Law Says About Paid Boosting
Article 57-C of Law 9,504 of 1997 bans paid online campaign propaganda except boosting by parties, coalitions and candidates. It allows boosting only to promote or benefit candidates or their parties.
Irregular boosting draws a fine of 5,000 to 30,000 reais (about US$990 to US$5,950), or twice the sum spent if larger. The first-round fine of 5,000 reais equals the legal minimum.
What It Means for US Readers
Meta, a US company, must enforce the order on Instagram and Facebook in a runoff that US investors watch closely. Brazilian judges can order American platforms to switch off paid political promotion within hours.
Paid attack ads are routine in US campaigns, so Brazil’s line between promoting a candidate and attacking a rival may look unfamiliar. The line applies to paid boosting only, because the video can stay online without payment.
Brazil votes on Sunday, 25 October, when Lula faces Flávio Bolsonaro, the conservative senator and son of ex-president Jair Bolsonaro. That makes the court’s handling of campaign advertising a live issue for the final 11 days.

What Is Not Known
The decision text could not be opened, and the court’s news page carries no item on it. The details above come from Correio Braziliense, Estadão Conteúdo (carried by Terra and O Liberal), A Crítica and Gazeta do Paraná.

Reports differ on the first-round piece: Agência Brasil called it a photo, A Crítica and Times Brasil a video. Correio Braziliense says the first-round caption was identical.
What Comes Next
The full court is due to review the single-judge order, but no date has been published. The court’s agenda for Thursday, 15 October, names three cases and none is this order.
