It's a friend. Sorry it's not been judged or publicized by anyone verifiable. It's a lowclass female friend whose husband was accused, the underage accuser said it was false, but because the accuser is a child, we cannot take her retractation as legitimate. Funny how the accusation still stood.

On the front yard of the court, the lawyer asked the wife for 1000€ cash to pay the judge, she's not wealthy so she could't withdraw that amount on her bank account, and her friends didn't scramble in time.

The man was convicted to 10 years, spent 6 actual years in prison. In normal times I'd doubt the story, but the fact that his wife fought for him, divorcing him only after the prison time, and still tells the same story, the consistency through time makes me believe she's legit.

Wait, is he convicted by a false accusation? Or was there some investigation about it first?

Not doubting the story, but another possibility would be the 1000€ "for the judge" actually being "for the lawyer's pocket". A lawyer extorting vulnerable clients would expect (sadly) to get away with it. A judge communicating bribery requests through lawyers likely couldn't.
