Legal challenges and inquiries have emerged following elections in the Brazilian states of Rondônia and Roraima.

In Rondônia, the Liberal Party (PL) filed a request with the Regional Electoral Court (TRE-RO) to investigate the extension of voting hours during the presidential second-round elections. Following a Supreme Federal Court decision by Minister Cristiano Zanin, voting in the state was extended until 6:00 PM. The PL is seeking data to distinguish between voters who were in line by 4:00 PM and those who arrived after the extension was announced, requesting a breakdown of votes by municipality and polling station.

Additionally, the TRE-RO dismissed a case against re-elected State Deputy Jean Mendonça. The Electoral Public Ministry had alleged that Mendonça engaged in irregular electioneering by using a large vehicle as an unauthorized stationary billboard. The defense argued the vehicle was a former mobile health unit that had been immobilized for 15 months due to mechanical issues.

In Roraima, the Superior Electoral Court (TSE) maintained the suspension of a legal process regarding the candidacy of Governor-elect Arthur Henrique and his running mate, Velton Quincozes Poleto. Although they won the supplementary election with nearly 61% of the vote, their registration was initially denied due to alleged failures to meet mandatory resignation deadlines. The case awaits a ruling from the Supreme Federal Court regarding rules for public officials competing in supplementary elections.
