In the present case, the DJ had thoroughly examined the evidence of both parties’ expert witnesses before concluding that the Prosecution expert’s (Dr Christopher Cheok’s) assessment of the appellant’s psychiatric condition and its contributory link (or lack thereof) to the offences was more reliable. I see no reason to disturb his finding. In particular, the DJ directed his mind to consider the reliability and objectivity of both expert witnesses. The DJ had good grounds to doubt the reliability and objectivity of the Defence’s expert witness, Dr Tommy Tan, who conceded during cross-examination that his assessment appeared to be “lopsided” given the undue emphasis placed on the appellant’s self-reporting and probably self-serving accounts. In addition, Dr Tan had omitted crucial details concerning the appellant’s high risk of reoffending in his report. Moreover, Dr Tan’s diagnosis that the appellant suffered from persistent depressive disorder was suspect as he had failed to take into account important factors in his assessment – a point which the appellant appears to have accepted, absent his contention of this point at this appeal.
