R v Uduma

The appeal concerned a conviction for causing serious bodily harm by dangerous driving, contrary to section 19A(3) of the *Criminal Law Consolidation Act 1935* (SA). The appellant, R v Uduma, was convicted by a Judge alone following a collision where his vehicle was on the incorrect side of the road, resulting in serious harm to the victim. The central dispute at trial was whether the appellant's driving constituted dangerous driving.

The legal issues before the Full Court of the Supreme Court of South Australia were whether the verdict was unsafe and unsatisfactory, and whether there was a reasonable hypothesis consistent with innocence. Specifically, the court considered the admissibility and use of expert evidence from police officers regarding average reaction times and the topic of headlights, and whether the trial Judge had misused this evidence or made calculations not supported by the evidence. The court also considered whether the trial Judge was entitled to consider scenarios not advanced by the defendant and whether a particular hypothesis regarding the collision was reasonable.

The Full Court, comprising Gray, Vanstone, and White JJ, dismissed the appeal. The court held that the evidence given by police officers concerning average reaction times was within their expertise, admissible, and properly used by the trial Judge. The Judge's calculations and consideration of possible scenarios, including those not raised by the defence, were found to be open on the evidence. The hypothesis that the collision occurred due to the appellant being blinded or distracted by headlights and swerving into the victim's path was deemed not to be a reasonable hypothesis, particularly given the implausibility of the sequence of events and the required reaction time. The court concluded that there was no miscarriage of justice and that the verdict of dangerous driving causing serious harm was not only open to the trial Judge but was overwhelmingly supported by the evidence and was the correct verdict.
