Again, you are clearly a child and have never had to pay bills if you think that the tiny amount they are allowed to withdraw is enough even to pay rent and food for a family with children.
More importantly it doesn't matter that they are being allowed a tiny amount of their own money. This is not stolen money, they have committed no crime, and they have not been accused of a crime. The crime is denying them their own money.
And no, there has not been an investigation or a court case, because, and I don't know why you seem incapable of understanding this simple fact: THEY DID NOT COMMIT A CRIME! Paying bills is not a crime.
There has been an investigation, and a ruling from the European Commission. He has also appealed that decision, which failed.
The sanctions come from the European Commission. Oh, wow, so you mean to tell me the EC said We investigated ourselves and found we did nothing wrong? Shocker. Appealing to them is like appealing to Hitler to ask that you be released from the concentration camp.
And the idea that they can't challenge the sanctions in court is utter bullshit. You absolutely can challenge them before the GCEU/ECJ
Except the only courts they can challenge this in are in Brussels and the sanctions ban them from traveling outside of Germany. Are you being purposely obtuse or are you just that dense that you don't understand how this is deliberately set up so they can't do anything?
