For the purpose of this and preceding section “intoxication” shall be deemed to include a state produced by narcotics or drugs. [27] It is apparent from the language of the above stated provisions that intoxication simpliciter is not a defence. It will only constitute a defence if the accused could bring himself within the purview sub section 2 of section 82 in that accused did not know his act or omission is wrong or that he did not know what he was doing. Sub-section 2 (a) provides that the state intoxication must have not been self-induced, in that the same was caused without his consent by malicious or negligent act of another party. What then of the cases 17 where the intoxication was a result of one’s own action, such as the case of over consumption of alcohol? Section 85(2)(b) seems to suggest that in a case where intoxication was self-induced or self-caused, the person must have reached the state of insanity at the time of the act or omission. Section 86 (2) of the Penal Code provides another important point: that in determining whether an accused person has the requisite mens rea at the time of the actus reus, the plea of intoxication must be taken into account. This then brings another question as to whether the word “insane’ in section 85(2)(b) would have the same meaning as the defence of unsoundness of mind in section 84 of the Penal Code. The Singapore Court of Appeal in Tan Chor Jin v PP [2008] 4 SLR(R) 306 took the view that “insanity” and the defence of unsoundness of mind in section 84 are two different concepts. VK Rajah JA, speaking for the Court had this to say: - “24. We are of the view that the two concepts – viz, unsoundness of mind in s 84 on the one hand and insanity by reason of intoxication in s 85(2)(b) on the other – are indeed different. One should not be too astute to attribute statutory superfluousness to Parliament where the use of the word “insane” in s 85(2)(b) is concerned. Section 85(2)(b) refers to a different basis for exoneration from that afforded by s 84 as the former is grounded on intoxication-induced insanity. In contrast, the unsoundness of mind embraced by s 84 refers to an abnormal state of mind that covers diseases and deficiencies of the mind, both of which are invariably permanent conditions. The reference to “temporarily or otherwise” in s 85(2)(b) is neither accidental nor superfluous. These words do not refer merely to the temporary symptoms or effects of intoxication. Rather, they refer to an abnormal state of mind that can, inter alia, be transient. In short, s 85(2)(b) reinforces the point 18 that an otherwise normal person can, under the influence of drink or drugs, become so intoxicated that he becomes legally “insane”. This condition of insanity can be transient, as opposed to the unsoundness of mind envisaged in s 84, which must be permanent. 25 Our view, as just stated in the preceding paragraph, also addresses the question posed at [20] above, viz, whether the intoxication-induced insanity referred to in s 85(2)(b) must be permanent or whether it can be transient. In deciding on this particular point, we found it useful to return to the underlying philosophy underpinning the defence of intoxication. It is undoubtedly true that an accused person who commits a crime while suffering from unsoundness of mind or without the requisite mens rea should not be viewed as meriting the same sanction as a person who commits a crime while of sound mind and/or while having the requisite mens rea. The phrase “temporarily or otherwise” in s 85(2)(b) cannot but mean that even transient episodes of intoxication-induced insanity are to be considered as being embraced by s 85(2)(b). The provision could apply to an accused even if he does not have a prior mental illness or pre-existing mental deficiency. It should not be restricted in its application, as has been suggested (see, eg, the quotation at [22] above), to an accused suffering from a mental disorder who experiences normalcy between his bouts of illnesses. Why should s 85(2)(b) be thus restricted given that an accused who lacks the requisite mens rea by reason of s 86(2) is entitled to an acquittal? To be clear, this does not necessarily mean that an accused who succeeds in proving intoxication-induced insanity under s 85(2)(b) will be completely exonerated and therefore remain at liberty to commit more mischief or crime. An accused who can become insane (whether temporarily or otherwise) under the influence of drink or drugs is a danger to society, and consideration needs to be given to how future recurrent instances of “insane” homicide by such an accused can be prevented. Indeed, s 86(1) of the Penal 19 Code prescribes that if an accused successfully invokes s 85(2)(b), “section 84 of this Code [ie, the Penal Code] and sections 314 and 315 of the Criminal Procedure Code shall apply”. In particular, s 315(1) of the Criminal Procedure Code (Cap 68, 1985 Rev Ed) requires the trial court, where it has found that the accused did commit the act in question, to “order [the accused] to be kept in safe custody in such place and manner as the court thinks fit” after the trial; this provision gives the trial court the option of ordering the accused to be, inter alia, confined in a mental hospital. Given the penal consequences that flow from a successful invocation of s 85(2)(b), it is not surprising that this provision will seldom be invoked by defence counsel if s 86(2) can be successfully relied on. Nevertheless, s 85(2)(b) does have its uses, as illustrated by cases such as Tan Ho Teck ([21] supra), which concerned an accused with a prior history of mental problems (the defence provided by s 85(2)(b) was successfully invoked in that case). As such, notwithstanding the rather limited utility of s 85(2)(b) and the practical reasons militating against its invocation, this provision should not be narrowly interpreted. We prefer to afford statutory defences greater interpretative latitude provided the interpretation adopted dovetails, in the final analysis, with both the letter and the intent of the provisions concerned.” That decision has been followed by this Court in PP v Aldwin Rojas Saz [2019] 6 MLJ 768 and Lee Thiam Whatt v PP [2019] MLJU 891. That controversy aside, what is critical is that it is for the accused to establish this defence of intoxication in one of the three ways alluded to in Tan Chor Jin v PP [2008] 4 SLR(R) 306. That said too, it is pertinent to observe that the Federal Court in Abdul Aziz Mohamed Shariff v. PP (2010) 5 CLJ 733 had occasion to hold as follows: 20 “To prove intoxication, it is incumbent upon the defence to adduce sufficient evidence to convince the court that this had rendered the accused incapable of forming the necessary intention or knowledge to commit the crime charged, or that 'he was by reason of intoxication insane, temporarily or otherwise, at the time when he committed the crime'. [17] The existence of evidence that: (a) the appellant had consumed a large quantity of alcohol or that it was even mixed with toddy, coupled with (b) the presence of a strong smell of alcohol, and (c) the opinions of relatives who are not medically qualified, that the appellant was drunk is insufficient to constitute a possible defence of intoxication against the preponderance of evidence indicating that he had intended to cause death to the deceased.” [28] From the above and the host of other authorities it is well settled law that the court in examining the plea of intoxication must consider all the available evidence including the accused’s conduct prior to, at the time and after the commission of the alleged offence- (see, Francis Antonysamy v. PP (2005) 2 CLJ 481; Abdul Aziz bin Mohamed Shariff v Public Prosecutor [2010] 6 MLJ 759; Public Prosecutor v Ramasamy a/l Sebastian [1991] 1 MLJ 75) [29] Several issues were raised by the appellant contending that the learned trial judge had erred in his decision. We will now deal with these issues. [30] The learned counsel for the appellant had submitted that the appellant’s conduct prior during and after the alleged incident clearly proved that the appellant was so intoxicated and that the appellant 21 was incapable of forming the intention to cause the death of the deceased. The appellant testimony can be gleaned from his evidence which merit consideration as follows: i. He was not aware of what happened at the playground from the time he slept at the playground until police woke him up; ii. He was not conscious and/or not aware at all about his surroundings at the material point of time; iii. There is no motive or any reason to injure or cause death of the deceased as the deceased was like a brother to him; and iv. He was still drunk when the police woke him up on the day of the incident. [31] Learned counsel further submitted that it is established during the prosecution’s case that the appellant was under the influence of alcohol at the material point of time. In such circumstances, the prosecution’s case corroborates the defence of the appellant that he was so intoxicated that there are doubts as to whether he could have formed the necessary intention to commit the offence alleged against him. [32] We have carefully examined the reasoning by the learned trial judge vis-a-vis the evidence as recorded. We are unable to agree with the submission of the learned counsel for the appellant that the 22 evidence of PW3 should be rejected in toto. On the contrary, we are of the view that the learned trial judge did examine the evidence of PW3 and applied the correct judicially accepted test. We are not persuaded by the submission of the learned counsel that discrepancies between eye witness account (PW3) and medical evidence (PW4) demolishes credibility of prosecution’s case. From the evidence recorded, there was ample evidence by PW3 who saw before her very own eyes that it was the appellant who had hurled the stone on to the head of the deceased. PW4, pathologist, testified that on an external examination of the deceased’s body, he found that the injuries to head was caused by a blunt object such as stone. In the post mortem report (Exh. P12) PW4 ruled out there was no significant natural disease found in his body that could have caused or contributed to his death at the particular moment in time. The post mortem report also revealed that the deceased had severe degree of blunt force trauma to the head. Injury No. 5 was the single most fatal injury. In the circumstances, we are of the considered view that the above finding was consistent with the evidence of PW3. [33] We are of the view that the ruling by the learned trial judge at the end of the case for the prosecution was correct. The court accepted PW3 as a credible witness who has no motive to lie in court. The court observed her demeanour when she broke down when learned defence counsel suggested to her that she was lying in court. She viewed the suggestion by the learned defence counsel as an affront to her credibility. In respect of the cause of death, the court was of the view that the head injury inflicted by the accused which according to PW4 was so severe that in the ordinary cause of nature would cause death under section 300 (d) of the Penal Code. Upon a 23 maximum evaluation of all the evidence by the prosecution witnesses, the court was of the considered view that the prosecution had succeeded in proving each and every ingredients of the offence and therefore called upon the accused to enter his defence as per the original charge under section 302 of the Penal Code. [34] In his final judgment at the end of the whole case, the learned trial judge said this inter alia:
