R v Bui

The case of R v Bui involved a dispute concerning the failure of the prosecution to disclose material in a timely fashion, resulting in unfairness to the accused. The matter was before the court to decide on the appropriate remedy, including the imposition of costs and the potential stay of proceedings. The accused argued that the prosecution's failure to disclose evidence in a timely manner prejudiced his ability to prepare his defence, leading to an unfair trial. The legal issues before the court included whether costs were payable to the accused due to the prosecution's failure to disclose, the principles applicable to disclosure by the prosecution, and whether a stay of proceedings was warranted in the circumstances.

The court considered the principles governing the duty of disclosure by the prosecution, emphasising the importance of timely disclosure to ensure a fair trial. It was established that the prosecution has a duty to disclose material that is relevant to the accused's defence or that might affect the case. The court found that the prosecution had failed to meet this obligation, resulting in significant prejudice to the accused. In response to this breach, the court ordered that the proceedings be stayed until the Director of Public Prosecutions paid the accused's reasonable costs incurred due to the oral application and the adjournment of the trial. The court held that a conditional stay of proceedings was appropriate in these exceptional circumstances, as the prosecution's failure to disclose had caused substantial unfairness to the accused.

Upon the payment of the costs by the Director of Public Prosecutions, the matter was to be returned to the list for further pre-trial directions. The court set aside the orders made on 7 June 2011 and mandated that the costs be agreed upon or assessed by a judge if agreement could not be reached. This decision underscores the importance of adherence to disclosure obligations and the court's willingness to impose sanctions, including a stay of proceedings, when the prosecution's actions result in significant prejudice to the accused.
