Cooper v The King

The appellant, Cooper, was convicted of exposing a child to an indecent act. The Crown alleged that the appellant intentionally exposed his penis to an eight-year-old female child. The appeal concerned whether the verdict was unreasonable and unsupported by the evidence presented at trial. The Full Court of the Supreme Court of South Australia, comprising Grant CJ, Barr and Hiley JJ, heard the appeal.

The primary legal issue before the Court was whether the jury’s verdict of guilt was unreasonable, given the purported inconsistencies, discrepancies, and inadequacies in the evidence identified by the appellant. A secondary issue, which informed the primary one, concerned the admissibility and probative value of certain "context" evidence, specifically an alleged prior incident involving the appellant and the complainant in a shower. The appellant argued this evidence was vague, carried a significant risk of misuse, and lacked sufficient probative value to be rationally capable of affecting the jury's assessment of a fact in issue.

The Court dismissed the ground of appeal concerning the unreasonableness of the verdict. It reasoned that the inconsistencies and discrepancies highlighted by the appellant did not, when considered rationally, create a reasonable doubt as to the appellant's guilt. Regarding the context evidence, the Court affirmed that such evidence, even if not satisfying the tendency rule, can be admissible for non-tendency purposes, such as providing essential background, explaining the offences charged, overcoming a false impression of an isolated event, and negativing issues like accident or mistake. The Court found that the evidence of the shower incident was potentially relevant and probative in demonstrating motive, preventing a false impression of an isolated event, dispelling the notion of conduct occurring "out of the blue," and assisting in determining whether the exposure was intentional or accidental. Therefore, if accepted by the jury, this evidence could rationally affect the assessment of the probability of material facts.
