Summary
This case involves Mohamed Mubin bin Abdul Rahman ("Mubin"), who was charged for abetting his brother Lokman bin Abdul Rahman ("Lokman") to traffic drugs. Lokman was arrested with two bundles of diamorphine, and claimed that Mubin had instructed him to take the bundles from their condominium unit and deliver them. Mubin denied any knowledge of the drugs. After trial, the court rejected Mubin's evidence and accepted Lokman's version of events.
Mubin was initially charged for abetting Lokman to traffic the drugs. However, on appeal, Mubin raised for the first time that he had been suffering from an abnormality of mind that substantially impaired his mental responsibility at the time of the offence. The matter was remitted to the High Court to hear evidence on Mubin's alleged abnormality of mind and determine if he satisfied the requirements under section 33B(3)(b) of the Misuse of Drugs Act.
After considering the expert evidence and submissions, the court found that Mubin did not satisfy the requirements under section 33B(3)(b) and thus the death penalty remained mandatory for his offence.
What Were the Facts of This Case?
Lokman was arrested on 8 September 2015 with two bundles of granular substances containing not less than 39.28g of diamorphine in his possession. Lokman claimed that Mubin had instructed him to take the bundles from their condominium unit, pass one bundle to a person named "Edy", and return the other to Mubin's residence. Mubin, who was subsequently arrested on 5 October 2015, denied any knowledge of the drugs in the condominium.
After trial, the court rejected Mubin's evidence and accepted Lokman's version of events. Lokman's original charge of trafficking was amended, and he was sentenced to life imprisonment under the Misuse of Drugs Act. Mubin was initially charged for abetting Lokman to traffic the drugs, but his charge was also altered. When the court dealt with Mubin's sentence, only section 33B(2) of the Misuse of Drugs Act arose for consideration, as no assertion was made that Mubin was of unsound mind. The death penalty was mandatory, and the court so ordered.
Mubin subsequently appealed against his conviction and sentence, and for the first time raised that he had been suffering from an abnormality of mind that substantially impaired his mental responsibility for his actions at the time of the offence. The matter was then remitted to the High Court to hear evidence on Mubin's alleged abnormality of mind.
What Were the Key Legal Issues?
The key legal issue in this case was whether Mubin satisfied the requirements under section 33B(3)(b) of the Misuse of Drugs Act, which provides an exception to the mandatory death penalty. Mubin bore the burden of establishing the following cumulative requirements on a balance of probabilities:
1. That he was suffering from an abnormality of mind;
2. That the abnormality of mind arose from a condition of arrested or retarded development of mind, or arose from any inherent causes, or was induced by disease or injury (the aetiology of the abnormality); and
3. That the abnormality of mind substantially impaired his mental responsibility for his acts and omissions in relation to his offence.
How Did the Court Analyse the Issues?
At the remittal hearing, the defence contended that Mubin was suffering from the following conditions at the time of the offence, which resulted in an abnormality of mind: Unspecified Stimulant-Related Disorder (Methamphetamine), Stimulant Withdrawal, and Adjustment Disorder.
The court examined the expert evidence provided by Dr Ung, who had conducted psychiatric assessments of Mubin and produced two reports. Dr Ung's diagnosis was that Mubin suffered from Unspecified Stimulant-Related Disorder and Stimulant Withdrawal. However, the court found that the evidence did not establish that these conditions arose from a condition of arrested or retarded development of mind, or from any inherent causes, or were induced by disease or injury, as required under the second limb of the test.
As for Adjustment Disorder, the court noted that this was based on Mubin's subjective report of various sources of stress in his life, including his medical condition, difficulties reintegrating into society after release from prison, and relationship issues. The court found that while these circumstances may have caused Mubin distress, they did not amount to an abnormality of mind that substantially impaired his mental responsibility.
The court also considered the surrounding circumstances, including the nature and scale of the drug trafficking offence, Mubin's prior criminal history, and his conduct before and after the offence. The court concluded that the evidence did not establish that Mubin's mental responsibility was substantially impaired at the time of the offence.
What Was the Outcome?
The court found that Mubin did not satisfy the requirements under section 33B(3)(b) of the Misuse of Drugs Act. Accordingly, the death penalty remained mandatory for his offence.
Why Does This Case Matter?
This case is significant as it provides further guidance on the application of the exception to the mandatory death penalty under section 33B(3)(b) of the Misuse of Drugs Act. The court's analysis of the expert evidence and the surrounding circumstances in determining whether the requirements of the provision are met is instructive for practitioners dealing with similar cases.
The case also highlights the importance of raising the issue of an accused's mental condition at the earliest opportunity, as the court noted that the issue of Mubin's alleged abnormality of mind was not raised or canvassed at the initial trial. This may have implications for the preparation and presentation of such defences in future cases.
