Its just that the executive and legislative are now so weakened due to corruption scandals (and open investigations) that no one seemingly dares to move against 1 wild judge.
I wonder how this ends though. 1 judge seemingly has more power now than a set of democratically elected senators
It got worse in 2019. Some magazine ran a damning article on them. In retaliation, they granted themselves virtually limitless power to investigate, prosecute, judge and punish "fake news" of all kinds, with themselves as the victims. They determine what's fake of course. Their powers just kept expanding until they essentially usurped everything. It got to the point this judge started proposing changes to laws directly to our representatives. The changes were rejected but he just rammed the "fake news" nonsense down our throats anyway via his "resolutions". It's under the umbrella of this "fake news" inquisition that the judge-king banned X in Brazil.
And not a single politician will move against them. Precisely because they're all so hopelessly corrupt. All the judges need to do to put them in the ground is unearth one of countless corruption scandals.
This is not a democracy, it's a dictatorship of the judiciary. Unelected judge-kings with lifetime mandates whose pens directly make the people with guns do their bidding. It's kind of ridiculous to even discuss "laws" at this point. These guys could write whatever they want on a piece of paper and it becomes law.
Even more context:
That said, I do think that judges in Brazil can have a larger investigative role due to the different legal system that does not happen in other countries with more separation of powers to prevent exactly this sort of thing.
