Director of Public Prosecutions (NSW) v Kirby

The case of Director of Public Prosecutions (NSW) v Kirby involved the Director of Public Prosecutions appealing against the dismissal of a charge against the respondent, Kirby, under section 112 of the Road Transport Act 2013. The respondent had been charged with driving under the influence of alcohol, a summary offence. Evidence showed that the respondent was intoxicated both before and after driving, and he admitted to having driven the vehicle. However, the magistrate dismissed the charge, focusing on whether the respondent's ability to drive was impaired, rather than the legal requirement that the offence be committed by driving when intoxicated.

The legal issues before the court included whether the magistrate correctly applied the law in dismissing the charge and if procedural fairness was observed. The court had to determine whether the dismissal was due to the magistrate considering an irrelevant factor or if the dismissal was based on one of the limbs of the case May v O'Sullivan. Additionally, the court needed to consider if the prosecutor was given an opportunity to make submissions regarding the second limb of May v O'Sullivan.

The Supreme Court found that the magistrate erred by focusing on whether the respondent's driving ability was impaired, which is not an element of the offence under section 112 of the Road Transport Act 2013. The court also found that the magistrate did not provide adequate reasons for dismissing the charge, leading to uncertainty about whether the dismissal was based on the first or second limb of May v O’Sullivan. The prosecutor was not given the opportunity to make submissions on the second limb, resulting in a denial of procedural fairness. Consequently, the appeal was allowed, and the case was remitted to the Local Court for further consideration.
