>nothing found in the conversations he [ilegally] acquired that demonstrates wrongdoing by the judge.

"In the files, conversations between lead prosecutor Deltan Dallagnol and then-presiding Judge Sergio Moro reveal that Moro offered strategic advice to prosecutors and passed on tips for new avenues of investigation. With these actions, Moro grossly overstepped the ethical lines that define the role of a judge. In Brazil, as in the United States, judges are required to be impartial and neutral, and are barred from secretly collaborating with one side in a case."

Are you claiming these conversations never happened?

These conversations happened in the clear. It was well known and disclosed at the time of the investigations that this judge (and a few others) were exchanging information about the case with prosecutors and defenders.

Also, "tips for new avenues of investigation" may be ethically questionable (although it's hard to make the case for that), it's not crime at all. It would be crime if the judge was taking sides in the ruling, which that specific judge is not accused of.
