Key legal question
Whether the visit ban for misuse of visitation rights was lawful
Extracted holding
The visit ban could be imposed even if the USB stick was brought in by the inmate himself for an unlawful transaction, because the visitation right was abused.
Extracted reasoning
The decisive point was the abuse of visitation rights; the asserted distinction in the prison form did not exclude a sanction, and the causal link between the planned unlawful act and the visit existed.
