Key legal question
Whether the detainee was entitled to unsupervised visits with his brother despite collusion risk.
Extracted holding
No. Given the seriousness of the alleged narcotics offences and the remaining co-participants at large, there was an evident risk of collusion, so unsupervised visits could be refused.
Extracted reasoning
The allegations were serious, only partly admitted, and several participants were still free; under those circumstances collusion risk was sufficiently pronounced.
