Chuguna v The State of Western Australia

The case of Chuguna v The State of Western Australia involves the appellant, who is facing charges of offering cannabis to a child under 13 years of age, attempting to indecently deal with a child under 13 years of age, and indecently dealing with a child of or over 13 years and under 16 years of age. The decision concerns the admissibility of cross-charge evidence under Section 31A of the Evidence Act, specifically whether evidence of a tendency to have a sexual interest in young female children and to act on that interest in public places has significant probative value and whether the probative value of the evidence compared to the risk of an unfair trial means that fair-minded people would think that the public interest in adducing all relevant evidence of guilt must have priority over the risk of an unfair trial. The court was required to decide whether the evidence of the charged offences was cross-admissible to prove the accused's propensity for engaging in such conduct.

The court considered the nature of the offences and the potential probative value of the evidence in establishing the accused's state of mind and propensity for engaging in such conduct. The court determined that the evidence of the charged offences was cross-admissible, as it had significant probative value in proving the accused's tendency to have a sexual interest in young female children and to act on that interest in public places. The court held that the probative value of the evidence compared to the risk of an unfair trial meant that fair-minded people would think that the public interest in adducing all relevant evidence of guilt must have priority over the risk of an unfair trial.

The court allowed the appeal, quashed the convictions and sentences, and ordered a retrial. The court held that the evidence of the charged offences was cross-admissible to prove the accused's propensity for engaging in such conduct and that the probative value of the evidence compared to the risk of an unfair trial meant that fair-minded people would think that the public interest in adducing all relevant evidence of guilt must have priority over the risk of an unfair trial. The court found that the evidence was relevant to proving the accused's state of mind and propensity for engaging in such conduct and that the probative value of the evidence outweighed the risk of an unfair trial. The court concluded that the evidence of the charged offences was admissible to prove the accused's tendency to have a sexual interest in young female children and to act on that interest in public places.
