(c) The learned trial judge failed to consider whether the appellant can avail himself of the defence of grave and sudden provocation although it was not put to the prosecution nor raised by the appellant. [13] In regard to the 1st and 2nd grounds, learned counsel argued that since there was no eye witness to the crime, the evidence as regard to the height of the appellant became very crucial. Learned counsel submitted that if the appellant was shorter than the deceased, then the wound caused could be consistent with the wound inflicted which slanted downtrend from the higher part to the lower part of the neck. If the appellant was of the same height with the deceased, then the wound caused would have been either parallel or slanting downtrend from the 14 higher part to the lower part of the neck. Learned counsel further submitted that if the appellant was taller than the deceased, then the wound would have been either parallel or slanting uptrend from the lower part to the higher part of the neck. [14] On the 3rd ground, learned counsel argued that since the learned trial judge had made findings of fact that the appellant had discovered about the deceased’s adultery and that the appellant had a quarrel with the deceased a day before the incident which must have inflamed the appellant to kill the deceased, it was suggested by learned counsel that any man in the appellant’s position would have been filled with uncontrolled rage and caused the death of the deceased unintentionally. Learned counsel’s complaint was that had the learned trial judge went on to consider whether the appellant can avail himself of the defence of grave and sudden provocation, the learned trial judge would have found and held that the appellant was entitled to the defence of sudden and grave provocation. Our Decision [15] In regard to the issue that no eye-witness who saw the appellant slitting the deceased’s throat, we agreed with the learned trial judge that there are strong circumstantial evidence to point the guilt of the 15 appellant. We had the opportunity to peruse the Appeal Records and we are of the considered view that the findings of the learned trial judge was not perverse in convicting the appellant. We found that there were cogent and overwhelming circumstantial evidence amply supporting the trial judge’s decision. We noted that the burden on the prosecution for this type of cases are much heavier one, but it has been fulfilled by the prosecution in the case before us. In PP v. Lin Lian Chen [1992] 2 MLJ 561, Edgar Joseph Jr., SCJ stated it summarily: “It is trite law that where the prosecution is relying on circumstantial evidence the onus upon it is a very heavy one and that evidence must point irresistibly to the guilt of the accused. If there are gaps in it then that will not be sufficient.”. [16] As we alluded to earlier in our judgment, the learned trial judge had relied on the strong circumstantial evidence which pointed to the appellant alone who committed the murder of the deceased. The appellant was the last person seen with the deceased, no one else present. The appellant threatened and quarreled with the deceased one day before the incident and continued in the morning before the incident took place. The appellant had told PW6 earlier that if the appellant came back he will kill his wife. Both PW7 and PW8 saw the appellant brought the murder weapon (P10) with him and had threatened to kill the 16 deceased while holding P10 when they had a quarrel. PW9 met the appellant a day after the incident and the appellant gave PW9 the knife P10 and asked the appellant to surrender to the police which the appellant later did. Finally, it was the appellant who brought the police team led by PW10 to recover the murder weapon and his clothes at the PW9’s house. [17] On the learned counsel’s complaint that the appellant’s clothes did not bear the deceased’s blood, this could be explained by the lack of evidence as regard to the manner how the incident had happened. It could have happened from the rear of the deceased in which case there was no possibility for the deceased’s blood to have smeared the appellant’s clothings. Even though the evidence of the blood are available, that evidence would only be considered as supportive in nature. We find no merits in the learned counsel’s complaint regarding the 1st ground of appeal. [18] On the issue that the prosecution failing to prove the height of the appellant, we disagree that it was fatal to the prosecution’s case. From the Appeal Records, it shows that even though this issue had been raised before the learned trial judge in the appellant’s learned counsel’s submission, the same issue was never put to the prosecution’s 17 witnesses. It is trite that the failure to cross examine a witness or to put the defence case during the prosecution’s case on a crucial part of the case would amount to an acceptance of the witness testimony and rendered the defence to be an afterthought (see Wong Swee Chin v. PP [1980] 1 LNS 138). [19] We find the learned counsel’s submission as regard the possibility of the wound suffered by the deceased much depended on the height of the assailant are a mere conjecture and from the bar table which we should not take into consideration. As we alluded to earlier there was no evidence as to how the incident occurred. No evidence as to the position of the deceased and the appellant at the time the injuries were inflicted, therefore the height of the assailant are not relevant. The fact whether the assailant was of the same height or different height with the deceased are not important and irrelevant. [20] The learned trial judge was right when his Lordship accepted the evidence of the pathologist (PW5) who had explained the injuries suffered by the deceased. In his judgment, the learned trial judge explained [pages 12 – 13 of the Appeal Record volume (1)]: 18 “[15] I accepted the evidence and findings of the Pathologist (PW5) who inter alia had found 2 injuries namely, an incision on the front of the neck and a bruise on the front of the chest [Refer to Q237 at p31 of the Notes of Proceedings]. She also found that there was no defensive wound to suggest any sign of a struggle [Refer to Q238 at p31 and Q284 at p55 – 56 of the Notes of Proceedings], that the fact that there was no defensive wound to suggest any sign of a struggle is more consistent with the deceased, being slashed and not suicide. [16] If the Accused contended that he tried to stop the deceased from slitting her own throat then there should be signs of a struggle but there was none. Furthermore from the nature, depth and severity of the deceased’s wound, as can be seen in the photographs which are produced as exhibits, I find that it cannot be self-inflicted as the nature and severity of the said wound can only be inflicted with considerable force and the wounds were more consistent with slashing with considerable force rather than slitting. If indeed the Accused did hold the Deceased’s hand and tried to stop her slitting her throat, I would not expect the wounds sustained by the Deceased to be so deep and severe.”. [21] The evidence of PW5 which are material to this case can be found at pages 31 – 33 of the Appeal Record volume (11) as follows: “Q237 How many injuries were found on the deceased’s body? 2 injuries, one incised wound on the front of the neck cutting the left neck muscle, the airway, left carotid artery, left jugular vein and the left vagus nerve. There was a bruise on the front of the chest. 19 Q238 From these injuries, were there any defensive wound? No Q239 Which injury caused his death? Incised wound on the neck. Q240 Upon your expert opinion what can cause such injury? Sharp object. Q241 From your expert opinion what was the deceased cause of death? Incised wound on the neck which injured the airway and blood vessels causing bleeding and death. Q242 From your expert opinion, were the injuries fatal in nature? Yes Q243 Why? Injury on the blood vessel caused massive and rapid bleeding. This resulted in one, in excessive lost of blood and two, no blood supply to the left side of the head and neck and almost two-third of the left side of the brain. The injury on the airway caused difficulty in breathing. Q244 From the injury, what was the chance of survival? Unlikely to survive. Q245 Were the injuries sufficient in ordinary course of nature to cause death? Yes Q246 Refer ID3 (17) and (18), based on your examination finding, can the incised wound on the neck be caused by self infliction? Possible but in this case not likely. Usually self inflicted fatal neck injury would have multiple tentative superficial cuts before the final fatal one inflicted. Sometimes they might have cuts on the wrist as well. In this case there was no other superficial cuts on the neck or on the wrist. 20 Q247 Have you ever conducted post mortem on self inflicted neck injury? Yes Q248 How many times? A few times, I cannot recall the exact number. Q249 From the injury on the neck, can you tell how was it inflicted? If right handed person stand in front or behind the deceased and slashed the deceased neck from the left to the right, it is possible to get this type of injury.”. [22] We found no merits in the learned counsel’s complaint on the issue of the appellant’s heights not being proven by the prosecution. [23] The final ground argued by the learned counsel before us was on the alleged failure of the learned trial judge to consider the defence of grave and sudden provocation available to the appellant. Learned counsel admitted that the defence of grave and sudden provocation was never put nor raised by the appellant in the court below. Learned counsel reiterates that the defence of the appellant was that the deceased slit her own throat. That explained the learned trial judge’s failure to consider whether the appellant can be availed himself for the defence of grave and sudden provocation. We are of the view that the learned trial judge could not be blamed for the failure simply because the 21 issue was never put and never raised before the learned trial judge. The same issue was only raised for the first time before us. [24] The law on the defence of grave and sudden provocation can be found under Exception 1 to section 300 of the Penal Code which provides: “Exception 1 – Culpable homicide is not murder if the offender, whilst deprived of the power of self control by grave and sudden provocation, causes the death of the person who gave the provocation, or causes the death of any other person by mistake or accident. The above exception is subject to the following provisos:
