The essentials
Electoral court says a two-hour voting extension, requested by both campaigns, did not affect the runoff results.
Supreme Court Justice Cristiano Zanin extended voting by two hours shortly before polls were due to close on runoff day. The extension was reported as applying nationwide.
Lula's campaign and Bolsonaro's campaign each requested the extension, citing different regional issues. The reporting does not specify what those issues were.
Polling stations in Brasília and Rio de Janeiro closed shortly after the original deadline, and the reporting does not explain how this relates to the extension. At a Rio de Janeiro polling station, voting machines could not be restarted after shutdown. The reporting does not state how long the problem lasted or how many voters it affected.
The president of the electoral court said the extension did not affect the results. Brazil's electronic voting machines have been used since the 1990s, and no significant fraud has been detected in that period. The reporting does not include responses from the campaigns to the court's assessment.
