Key legal question
Whether the refusal of pretrial prison transfer was lawful despite the accused's request.
Extracted holding
The refusal was upheld because important interests of the investigation, namely concrete collusion risk, opposed the transfer.
Extracted reasoning
Pretrial prison transfer under cantonal law may be refused if investigation interests require it. Given the accused's close relationship with a heavily incriminating co-accused, prior contacts, attempted indirect communication, and the nature of the alleged organised drug trafficking, serious indications of collusion existed.
