Where to begin...
The Brazilian supreme court essentially runs the country monocratically alongside the executive, bypassing the senate and congress.
We had to elect enough opposition senators to form an absolute majority in the senate with the explicit goal of impeaching the supreme court judges for infinitely worse violations than this.
Even after this herculean effort, nothing is guaranteed. The judges are nearly omnipotent and might just find a crime to hang our senators with before 2027. The crime of the day is foreign influence: they accuse our senators of having been financed by Americans.
Integrity has left this country a long time ago.
And ... I didn't read this as an attempt to catch the court shirking it's duties. They weren't going to report the court, they were just going to take advantage of having achieved a low profile for the case.
