Miller v DPP [2018] EWHC 262 (Admin)

"This is an appeal by way of case stated from a pre-trial ruling of the Black Country Magistrates' Court sitting at Dudley on 13 October 2016 in respect of an information preferred against the Appellant for failing to provide a specimen of blood in breach of section 7 of the Road Traffic Act 1988, not to exercise its discretion under section 78 of the Police and Criminal Evidence Act 1984 to exclude evidence of the drug drive procedure at Oldbury Police Station that led to the charge being made. ... On 24 June 2016, the Appellant was stopped by the police on suspicion of driving under the influence of drugs. When arrested and taken into custody, he behaved erratically and aggressively. It appears that he was known to the police as a person who had learning difficulties and autism. ... As Mr Scott submitted, the presence of an appropriate adult (whilst not being able to provide technical, legal or medical advice) would have provided the Appellant with the opportunity not only to have the question as to whether or not to provide a sample explained to him, but also to obtain an appreciation of the consequences of failing to do so. He points out that the offence of failing to provide a blood sample is predicated not only on the person's comprehension of the requirement to provide a sample, but also of the consequences of failing to do so in terms of criminal liability. The Appellant was clearly very exercised whilst being detained, and there is a very real possibility that the presence of an appropriate adult would have calmed him, and led him to behave differently and make different choices from those he in fact made. ... [H]aving found there to have been a breach of Code C in failing to inform and summon an appropriate adult to the police station, we do not consider that the magistrates did properly exercise their discretion under section 78 of PACE not to exclude the evidence of the drug drive procedure. Their reasoning was, unfortunately, fundamentally flawed; and, had they exercised their discretion properly, they would have been bound to have excluded the evidence of the drug drive procedure."
