That it will be so is because three of the five judges in the case have now announced that they will convict him, which is what is required to reach a majority decision.
Earlier in the week, two judges landed in a conviction, which in turn was followed by a third choosing to acquit on Thursday night because he considered the case to be political.
Late on Thursday evening, the fourth of them decided to convict the ex-president. The fifth judge's decision remains. The sentence will be announced when all judges have announced their decisions. It is clear that the 70-year-old risks a lengthy prison sentence.
Bolsonaro has been under house arrest since before, awaiting the verdict. The case concerns the events after the presidential election in 2022, where Bolsonaro is accused of having tried to stage a coup to be able to retain power.
