Meta owns Facebook, Instagram and WhatsApp, and the request came four days before the vote.

The statement lands in the final week of the Brazil election 2026 runoff between Luiz Inácio Lula da Silva, Brazil’s president, and Flávio Bolsonaro, senator for Rio de Janeiro. It names no candidate, but Lula’s campaign has accused Meta of hurting the reach of its posts, Veja reported.
What the UN Experts Said
The experts cited reports of restrictions on legitimate political expression on Meta platforms during the election. Monitoring reports, they said, show thousands of accounts and posts facing suspensions, reduced visibility and sharing limits, including journalists, rights defenders and content creators.
The statement says information, including from Meta employees, suggests accounts linked to one side of the presidential race were “disproportionately curtailed,” France 24 reported. The experts add that “where political expression appears disproportionately restricted, platforms must explain why, address unequal impacts and ensure effective remedies.”
They list temporary interruptions of one candidate’s campaign account and differences in engagement, reach and view counts. They also cite restrictions on that campaign’s Instagram posts and differences between the main parties in AI image generation, WhatsApp channel search results and candidates’ Stories.
The experts call on Meta to give explanations and ways to seek redress, apply its rules consistently and review complaints during the election itself. They warn that remedies that come late in an election can have irreversible consequences, according to Brasil de Fato.

How Meta and the Court Fit In
Meta says it has complied with a Brazilian court order to treat both campaigns equally and denies taking any action to favour one side, France 24 reported. It also told the electoral court (TSE) that it followed the order, as we reported when Meta told the court it complied.
A TSE justice ordered Meta to apply the same rules to both candidates until the runoff, banning unequal limits on reach, recommendations and search results, Poder360 reported. The experts note that order and defend an independent and impartial judiciary.
The UN experts are named by the UN Human Rights Council but act independently and do not speak for the organisation, Brasil de Fato noted. The signatories include Leopoldo Maldonado Gutiérrez, special rapporteur on freedom of expression, and Margaret Satterthwaite, special rapporteur on the independence of judges and lawyers.
What It Means for US Readers
Meta is a US company, so a UN call on its election conduct in Latin America’s largest economy touches shareholders and US policymakers alike. The case shows how foreign courts and global bodies now judge how American platforms treat political speech abroad.
Investors in Brazilian assets will watch whether the dispute over platform rules adds doubt to the vote. For Americans, it echoes domestic debates over how social networks rank and limit political posts.
