The client was prosecuted for driving with excess alcohol (69 in breath). The issues in the case were insufficient alcohol was consumed to exceed the prescribed limit, the roadside breath level was incompatible, the timings on the printout were incorrect and officers had failed to switch off police radios to comply with home office guidance. Philip Lucas instructed by Neil Blackaby (reviewing lawyer) successfully persuaded the Court to exclude the MG DD/ A breath specimen booklet in the case as the prosecution had failed to include maintenance logs and calibration certificates in the schedule of unused material.
