In 2015 I represented Mr B in drink drive proceedings following his provision of two samples of urine. Careful analysis of the process followed by police revealed that they had not provided my client with his share of the sample in accordance with the statutory requirement to do so. It had been delayed by a short but critical period of time. Samples had been taken on the 25 December but my client’s share was made available on the 30 January. Prosecution accepted it created a risk the police had breached Section 15(5) of the Road Traffic Offenders Act 1988. The charge was dropped by CPS.
