In determining the mitigating value to be attributed to an offender’s mental condition, the key question is whether the nature of the mental condition is such that the individual retains substantially the mental ability or capacity to control or refrain himself when he commits the criminal acts. If the individual’s ability to refrain himself is not impaired, and he instead chooses not to exercise his self-control, then the presence of the mental condition will be given little or no mitigating value (see Public Prosecutor v Chong Hou En [2015] 3 SLR 222 (“Chong Hou En”) at [28]). In the present case, the Appellant was diagnosed by Dr Ang to suffer from “[d]epressive illness with obsessive-compulsive features.” According to Dr Ang, the Appellant’s taking of the “upskirt” videos were impulsive and were his means to obtain relief from the tension and rejection he felt in life. Having considered the circumstances of the case, I find that the Appellant has not established that his ability to control his impulses had been impaired by his alleged mental condition. The manner in which the Appellant executed the offences, the long period of offending without discovery, the number of offences and the particular victims he targeted all show that the Appellant’s commission of the offences was calculated and opportunistic. This runs counter to Mr Quek’s assertion that his mental condition robbed him of his self-control. I am unable to accept that the Appellant did not harbour any ill intentions when he arranged to meet the victims. Nor could I accept that he was seized on each occasion with an uncontrollable impulse to film them only upon meeting them. I therefore give no mitigating value to the Appellant’s alleged mental condition.
