The client was prosecuted for driving with excess alcohol. The issues in the case included post driving alcohol (hip flask defence). The police obtained a back track calculation which was favourable to the Defendant as it showed her breath alcohol level would have been zero at the time of driving and between 19 and 61 after post driving alcohol which was consistent with the breath test printout which was 46. The police misinterpreted the report to mean she was over the prescribed limit at the time of driving. Laura Heywood (reviewing lawyer) wrote to the prosecution pointing out this discrepancy and persuaded them to discontinue the charges before the second hearing which was listed for trial.
