Prison – Discipline. The claimant Muslim prisoner was found guilty of disobeying a lawful order after he had refused to undergo a drug test when he was fasting in observance of a religious festival. The Administrative Court dismissed the claimant's application for judicial review of the defendant prison governor's decision as he had been right to find that the request that the claimant undergo a drug test had been reasonable and therefore lawful. To adopt an approach of not testing the claimant on days when he was observing a fast would be to undermine the random nature of the drug testing programme.
