R v Houghton and Roussetty

In the Supreme Court of South Australia, the appellants, Houghton and Roussetty, sought to appeal their convictions on the basis that fresh evidence had become available after their trial. The appellants had been convicted of various charges, including fraud and false representation, following a lengthy trial. The crux of their appeal was that critical evidence, which had not been heard at the trial, could have influenced the outcome of the proceedings had it been presented. This fresh evidence pertained to the credibility of a key witness whose testimony was pivotal in securing their convictions.

The legal issues before the court centred on whether the fresh evidence was sufficiently cogent and relevant to warrant a new trial. The appellants argued that the evidence was not only material but also significant in undermining the witness's credibility. They contended that their legal representatives had no reason to suspect the availability of this evidence prior to the trial, thus it could not be deemed as an omission on their part. The prosecution, on the other hand, argued that the fresh evidence did not alter the overall context of the case and was merely cumulative.

The court found that the fresh evidence was indeed cogent and relevant, and had the potential to significantly impact the jury's assessment of the witness's credibility. The court held that the appellants had discharged the onus of proving that the fresh evidence was material and that there were no grounds to suspect the evidence's availability prior to the trial. Given the pivotal role of the witness's testimony, the court concluded that a new trial was warranted to ensure a fair trial process. Consequently, the court allowed the appeals against the convictions, set aside the convictions, and ordered a new trial for both appellants.
