(vii) In the latest Federal Court case of PP v Mohd Rozani Bin Yahaya (MPRJ No: 05(LB)-117-11/2023(D)), the primary issue decided was whether, in light of the defence of insanity raised by the accused, the trial judge could order his acquittal at the end of the case of prosecution. Section 84 of the Penal Code codifies the defence of unsoundness of mind, where a person is incapable of knowing the nature of the act, or that he is doing what is either wrong or contrary to law. Her Ladyship Zabariah Mohd Yusof FCJ explained the difference between “medical insanity” and “legal insanity”. It was noted that “medical insanity” concerned a “disorder of the mind which covers a whole range of mental health conditions which may impair one’s cognitive or emotional functions”. Examples of such conditions are anxiety and depression. However, it was observed that these conditions do not necessarily render one as legally insane under section 84 of the Penal Code, so as to accord a complete defence in criminal law. In contrast, “legal insanity” was explained to involve “a distinct set of criteria and considerations within the framework of the legal system. It goes beyond mental health and pertains to one’s legal capacity and responsibility for their actions. It also entails assessment by mental health experts and legal professionals to analyse and evaluate the accused’s mental state at the time of the alleged offence committed. It was noted that the consequences of legal insanity may result in the accused being declared not criminally responsible or being committed to a psychiatric institution instead of facing traditional criminal penalties. The Federal Court then observed that a two-stage process would arise when the defence of insanity is raised. The first stage involves a determination of whether the accused was medically insane at the time when he committed the alleged offence. This is premised on the evidence of medical experts. The second stage involves an assessment of whether the accused, by reason of his psychiatric condition, has lost his cognitive faculties to a degree that he is incapable of knowing the nature of his act or that reason of his psychiatric condition, has lost his cognitive faculties to a degree that he is incapable of knowing the nature of his act or that what he is doing is wrong or contrary to law. The second stage requires a determination by the court based on the evidence adduced at trial. The trial judge in the case had rejected the evidence of the medical consultant because of the delay in the consultant’s examination of the accused, which took place nine (9) months after the incident and that the consultant had no immediate medical records of his condition from time of commission of crime. It was decided by the Federal Court that such delays by itself, do not invalidate the conclusions drawn by a medical professional. Moreover, the medical consultant SP9 was able to make reliable inferences based on medical records and other evidence. The need for expert medical evidence to substantiate the defence of insanity was emphasised. The evidence of SP 9 was before the court, which established the mental state of the accused at the time of the offence, that the accused was of sound mind at the material time. The Federal Court then held that the Court of Appeal when affirming the decision of the High Court, had erred in electing not to follow the principle in PP v. Lim Poo Teck (2024) 1 MLJ 337 that acquittals should not occur prematurely based solely on medical testimony without hearing the defence. Legal insanity has to be proven by the defence before the defence of insanity under section 84 applies. It was ultimately held that acquitting the accused before defence is called amounts to acquitting the accused before the defence of legal insanity under section 84 of the Penal Code is proven, which is an error of law. The Federal Court had then allowed the appeal by Prosecution and remitted the case to the High Court for continued trial and for the accused to enter on his defence. (In the present case, it was the SCJ who had ordered for the accused to be sent for medical assessment, pursuant to which the psychiatrist had prepared a report in the form of P4B confirming his mental condition at the time of commission of offence, but fit to stand trial. The trial then progressed, the accused had no legal representation. He did not cross-examine the witnesses for the prosecution but at the end of the case of prosecution had explained to the court that he was not aware what he was doing at the time of making communication in his twitter application, and he did not know what he did was contrary to the law. The SCJ had found that the prosecution had been unsuccessful in making out or proving a prima facie case, as there was no evidence on the intent of the accused to annoy others by making the posting, which is the mens rea element to be proven by the prosecution. Falling short of that, the SCJ decided that the prosecution had not proven a prima facie case for her to order the accused to enter on his defence to the preferred charges. Therefore, in the present case, the SCJ was mindful of both medical and legal insanity. She had accepted the evidence and report of the psychiatrist and had also appreciated the application of section 84 of the Penal Code, which codifies legal insanity. It was only after that, she had decided to acquit the accused person on the premise that the prosecution had not established a prima facie case and not because he had suffered unsoundness of mind at the time of commission of offence. Coupled with the lack of proof, the SCJ had embarked on an evaluation of the evidence tendered by the prosecution in its entirety, which includes the testimony of SP3, the medical expert who had expressed his medical opinion on the medical insanity of the accused which also syncs with the explanation offered by the accused at the close of the case of prosecution). [13] The SCJ had embarked on the trial of the case correctly and in accordance with the law as discussed above. In fact, Ratanlal & Dhirajlal in Law of Crimes, A commentary on Indian Penal Code, 1860, 29th edition, at page 394 has this to say on the duty of the court when dealing with an accused who suffers unsoundness of mind - when a plea of insanity is set up by the accused, the burden of proof is on him to prove it. But a man, who is insane will not be able to defend himself properly and effectively. It is, therefore, the duty of the court to look after the defence of the accused in the light of the evidence on record. Finding and the decision made by the SCJ in the present case is also fortified by the decision of the Supreme Court of India in the case of Bhikari AIR 1966 SC 1, 3, where it is observed: Undoubtedly it is for the prosecution to prove beyond reasonable doubt that the accused had committed the offence with the requisite mens rea. Once that is done a presumption that the accused was sane can rebut it either by leading evidence or by relying upon the prosecution evidence itself. If upon the evidence adduced in the case whether by the prosecution or by the accused a reasonable doubt is created in the mind of the court as regards one or more of the ingredients of the offence, including mens rea of the accused he would be acquitted. This is very different from saying that the prosecution must also establish the sanity of the accused at the time of commission of the offence despite what has been expressly provided for in section 105 of the Evidence Act. [14] Following on, as the appeal by the accused is against the judgment by the SCJ who has found the accused not guilty, pursuant to section 307 (1) of the Criminal Procedure Code (CPC/Act 593), this court could only reverse the decision and judgment of the SCJ if it smacks on an error of fact or law or both. Briefly, there has to be an appealable error committed by the SCJ. Only then, this court would be able to exercise appellate intervention. If not, this court is left with no alternative but to restore the order of acquittal made in favour of the accused. It is so in the present case, as for the finding of not guilty, upon curial scrutiny of the evidence tendered in this case by the prosecution against the accused and the explanation advanced by the accused, I do not see any justification for this court to disturb the said finding of fact and law, as it is in tandem with the evidence proffered in the case and the law applicable to the facts, circumstances of the case and the offences committed by the accused, as per the preferred charges against him. Ensuing from the above, there is no apparent or compelling reason for this court to interfere with the findings arrived at and the decision made by the SCJ, as it is in accord with the circumstance of the case involving the accused and it syncs with the law applicable. Thus, it is not plainly wrong. [15] As such, the order of acquittal and discharge of the accused is affirmed and the appeal by the prosecution is thus dismissed. It is recorded that the accused was not present in court for the decision but his advocate was present. His presence was dispensed with by this court, as he was travelling from the north to attend the court session. Moreover, the decision made in this appeal does not in any way prejudice him, as it is an affirmation of the order of acquittal and discharge already made by the SCJ earlier. Order of acquittal and discharge affirmed. Dated 19 December 2024 SGD Muniandy Kannyappan Judge, High Court 2 (Criminal) Kuala Lumpur.
