And if you consider first mandate crimes, then there are a lot of crimes. It wasnt just a technicality, it was a large fiscal fraud in an election year. As well as allegations of obstruction of justice and cover-up of corporate corruption
What these journalists don't seem to get is that Brazil had a president impeachment in the past (Collor) based on illegally collected evidence. The legal technicalities didn't matter, if you have a criminal in office, he needs to go. How the evidence was collected is the least of concerns. In the actual judicial trial, he actually won a few years later based on that defense (as he should have). But to want to keep in office someome who is a known criminal based on legal technicalities, seem absurd to me and to most of the country. So the consensus was that it was the right thing to do
An impeachment is mostly a political trial anyway. If justice was what the constitution was after, the trial would happen at the supreme court or, at the supreme court AND congress. But it only happens in congress. Where a president will have enemies, opponents, people with conflicts of interest, etc. There is no filtering process like a juri would have.
An impeachment by its very nature is one of the most unfair trials ever! Which means its mostly political and its very close to the confidence vote that is regularly used in Europe. The differences, in pratice, are minimal
