Knight v The Queen and Cassidy v The Queen

The case of *Knight v The Queen* and *Cassidy v The Queen* concerned appeals against conviction and sentence by the appellants, Knight and Cassidy. The appeals were heard by Mildren, Southwood, and Kelly JJ. The appellants were convicted of aggravated assault, with the prosecution alleging common purpose and aiding and abetting. The defence for Cassidy maintained he acted in self-defence and that no common purpose existed, while Knight argued he only became involved when he felt threatened.

The primary legal issues before the court were whether the trial judge erred in failing to adequately warn the jury about the potential dangers of relying solely on CCTV footage, given its limitations in coverage and timing, and whether a sufficient causal link was established between the appellants' actions and the injuries sustained by the Mahoney brothers. Additionally, the court considered the appellants' submissions regarding the absence of common purpose and the validity of their involvement in the assaults.

The court found no substance to the grounds of appeal against conviction. Regarding the CCTV evidence, the judges noted that the trial judge had drawn the jury's attention to the timing issues and the submissions made by counsel concerning it, and that no objection was taken to the instructions given. The court also found that the admitted injuries sustained by the Mahoney brothers were a result of the fight that took place, and that the causal link was established. The appeals against conviction were dismissed.

The appeal against sentence by Cassidy was also dismissed. The sentencing judge found that the attendance of the six men at the hotel was pursuant to a common purpose for a revenge attack, describing the violence as frightening and cowardly. The judge emphasised the need for general deterrence for organised and public violence motivated by revenge, and that such vigilante conduct would not be tolerated. Despite Cassidy's limited criminal history and positive personal circumstances, the court found the sentence of two years and six months imprisonment with a non-parole period of 15 months to be appropriate.
