Marshall and Richardson v Tasmania

Marshall and Richardson appealed their convictions to the Full Court of the Supreme Court of Tasmania following a trial before a judge and jury. The central issue on appeal concerned alleged irregularities in relation to the jury, specifically the discovery of printouts within the jury room after the verdict had been delivered. These printouts contained information regarding the meaning of "beyond reasonable doubt" and guidance on dealing with circumstantial evidence.

The Full Court was required to determine whether these irregularities had affected the verdict and, if so, whether the jury would have returned the same verdict had the irregularities not occurred. The court also had to consider the impact of the trial judge's directions on these questions.

The Court reasoned that while the presence of the printouts constituted an irregularity, it did not necessarily vitiate the verdict. The judges applied the principle that an irregularity will only lead to a new trial if it can be shown to have actually affected the verdict or if there is a real possibility that it did. In this instance, the Court found that the directions given by the trial judge were clear and comprehensive, and that the jury had been properly instructed on the relevant legal principles. Consequently, the Court concluded that the jury would have reached the same verdict even in the absence of the printouts.

The appeals were accordingly dismissed.
