Evidence of general behavioural changes in a complainant cannot be left to the jury as corroborative of sexual offending where the changes are not linked to any specific incident, there is uncertainty about temporal connection with the offending, the changes reflect a worsening of pre-existing behavioural problems, and there are contradictions in the evidence about the complainant's willingness to associate with the accused. The court left open the broader question of whether general behavioural change evidence is ever admissible as corroboration.
