The case demonstrates the application of the Pell v The Queen framework to an unreasonable verdict appeal where the key prosecution evidence came from a prison informant. Multiple soft tissue injuries caused by moderate blunt force, even when numerous, do not necessarily support an inference of intent to cause really serious injury, particularly where the injuries are relatively superficial and may have been inflicted over a protracted period. A prison informant's evidence may be found so unreliable on appeal that no rational jury could have accepted it, where the informant had a motive to fabricate, made inconsistent statements, and the circumstances of the alleged admissions were implausible. Separately, the case confirms that an assault can be found to be a substantial and operative cause of death even where GHB ingestion was also a possible contributing factor, provided the jury could exclude GHB alone as the cause.
