Even if the trial was annulled due to procedural fraud (which it wasn’t), it doesn’t take away his corruption and what his group did to the country.
One can argue that there have been numerous procedural frauds in Bolsonaro's trial - but of course if it’s the other side you don’t care ;)
The fact is that Lula was not convicted.
And he was convicted. By several judges. It was the supreme court that voided Lava Jato. Essentially, they him in the presidential race specifically to take out Bolsonaro.
Hopefully tomorrow he will prove useless at even that, and his party will be buried for good.
