Summarize the following court judgment. N: Criminal Appeal No. 543 of 1976. Appeal by special leave from the judgment and order dated the 6th May 1975 of the Rajasthan High Court in D.B. Criminal Jail Appeal Nos. 277	 413 to 416 and 918 of 1971. Badri Das Sharma for the Appellant. Dalveer Bhandari for the Respondent. The Judgment of the Court was delivered by BAHARUL ISLAM	 J. This appeal by special leave on behalf of the State of Rajasthan is directed against the judgment of the Rajasthan High Court acquitting the two respondents	 Shrimati Kalki alias Kali and her husband	 Amara (alongwith four other co accused). Respondent Kalki was convicted under Section 302 and Section 148 of the Penal Code and sentenced to imprisonment for life and for rigorous imprisonment for two years	 respectively. The five other accused persons including respondent	 Amara	 were convicted under Section 302 read with Section 149 and under Section 147 of the Penal Code	 and each of them was sentenced to imprisonment for life and to one and a half years rigorous imprisonment respectively. The material facts of the prosecution case were that there was a land dispute between Nimba (P.W.6) father of the deceased	 Poona	 on the one hand	 and respondent Amara and the members of his family	 on the other. On July 17	 1970 at about sunset the accused persons of whom respondent Kalki was armed with an axe and respondent	 Amara with a dharia	 came to the house of the deceased. At that time the deceased was inside his hut with his wife Mooli (P.W.1). Amara called Poona. Poona came out followed by his wife Mooli	 when he was knocked down by Amara and Rama whereupon Kalki gave him blow with the axe on the neck. Poona met with instantaneous death. Mooli (P.W.1) raised an outcry when Geli	 mother of the deceased (P.W.2) who had been at some distance from the hut came running to the place of occurrence and saw the assailants leaving the place. 506 3. Nimba lodged a report at the police station at Nana. Police registered a case. In due course the case was sent to	 and tried by	 the Session Judge who convicted and sentenced the six accused persons including the two respondents as stated above. This Court granted special leave to appeal only against the two respondents and refused it as against the other four. The question before us is whether the two respondents or any of them caused the death of Poona. There is no dispute that Poona met a homicidal death. The High Court has set aside the Order of conviction and sentence passed by the Session Judge on the grounds (1) that P.W.1 the widow of the deceased "is. a highly interested witness	 in as much as	 she is the wife of the deceased and there was an enmity between the deceased and the accused on account of the dispute about the agricultural land"	 and (2) "that there are material discrepancies in her statement". We have been led through the evidence of P.W. 1	 the only eye witness in the case	 of P.W.2	 Geli	 who says that she saw the respondents leaving the place of occurrence with the weapons in their hands	 and of P.W.5 the Medical Officer	 who held the Post Mortem examination on the deceased. His evidence fully supports the evidence of P.W.1	 who deposed that respondent Kalki gave a blow on the neck of the deceased with an axe. P.W. 5 found one incised wound measuring 5" X 2" X 4" on the lateral side of the left side of neck. On a perusal of the evidence of these witnesses	 we do not have the least doubt in our mind that it was respondent Kalki who gave an axe blow on the neck of the deceased and that respondent Amara came along with his wife with a dharia with the common intention of causing the death of Poona. In fact it was he who called out Poona from inside the hut	 and felled down and facilitated the murder of Poona by his wife	 Kalki. As mentioned above the High Court has declined to rely on the evidence of P.W.1 on two grounds: (1) she was a "highly interested" witness because she "is the wife of the deceased"	 and (2) there were discrepancies in her evidence. With respect	 in our opinion	 both the grounds are invalid. For	 in the circumstances of the case	 she was the only and most natural witness; she was the only person present in the hut with the deceased at the time of the occurrence	 and the only person who saw the occurrence. True	 it is she is the wife of the deceased; but she cannot be called an 'interested ' 507 witness. She is related to the deceased. 'Related ' is not equivalent to 'interested '. A witness may be called 'interested ' only when he or she derives some benefit from the result of a litigation; in the decree in a civil case	 or in seeing an accused person punished. A witness who is a natural one and is the only possible eye witness in the circumstances of a case cannot be said to be 'interested '. In the instant case P.W.1 had no interest in protecting the real culprit	 and falsely implicating the respondents. The second ground on which the High Court refused to place reliance on the evidence of P.W. 1 was that there were "material discrepancies". As indicated above we have perused the evidence of P.W. 1. We have not found any "material discrepancies" in her evidence. The discrepancies referred to by the High Court are	 in our opinion	 minor	 insignificant	 natural and not 'material '. The discrepancies are with regard to as to which accused "pressed the deceased and at which part of the body to the ground and sat on which part of the body; with regard to whether the respondent Kalki gave the axe blow to the deceased while the latter was standing or lying on the ground	 and whether the blow was given from the side of the head or from the side of the legs. In the depositions of witnesses there are always some normal discrepancies however honest and truthful they may be. These discrepancies are due to normal errors of observation	 normal errors of memory due to lapse of time	 due to mental disposition such as shock and horror at the time of the occurrence	 and the like. Material discrepancies are those which are not normal	 and not expected of a normal person. As indicated above we have not found any material discrepancies in the evidence of the P. W. 1. 7. Learned counsel for the respondent submitted that the appeal involved only appreciation of evidence and this Court may not interfere with the findings of facts resulting from appreciation of evidence. It is true that in an appeal under Article 136 of the Constitution this Court normally does not interfere with findings of facts arrived at by the High Court. But when it appears that the findings of facts arrived at are bordering on perversity and result in miscarriage of justice	 this Court will not decline to quash such findings to prevent the miscarriage of justice. In our opinion the guilt of the two respondents has been established by the prosecution beyond reasonable doubt and their acquittal resulted in grave miscarriage of justice. 508 In the result we set aside the order of acquittal passed by the learned High Court and convict respondent Kalki alias Kali under section 302 of the Penal Code and respondent	 Amara	 under Section 302/34 of the Penal Code	 and sentence each of them to suffer imprisonment for life. The appeal is allowed. The respondents are said to be on bail. They shall surrender forthwith to serve out their sentences. V.D.K. Appeal allowed.

Respondent Kalki alias Kali and her husband Amara (along with four other co accused) were charged	 convicted under section 302 I.P.C. and sentenced to life imprisonment. While Kalki was also convicted and sentenced under section 148 I.P.C. for two years ' rigorous imprisonment	 the other five accused were convicted and sentenced under section 147 I.P.C. for rigorous imprisonment for a period of one and a half years. In appeal the High Court of Rajasthan acquitted all of them on the grounds (i) that P.W. 1	 the widow of the deceased "is. . a highly interested witness	 inasmuch as	 she is the wife of the deceased and there was an enmity between the deceased and the accused on account of the dispute about the agricultural land" and (ii) "that there are material discrepancies in her statement". This Court granted special leave to appeal only against Kalki and her husband and refused it as against the four. Dismissing the appeal	 the Court ^ HELD: 1. It is true that in an appeal under Article 136 of the Constitution the Supreme Court normally does not interfere with findings of facts arrived at by the High Court. But when it appears that the findings of facts arrived at are bordering on perversity and have resulted in miscarriage of justice	 the Court will not decline to quash such findings to prevent miscarriage of justice. [507 F G] 2. Material discrepancies are those which are not normal	 and not expected of a normal person. In the depositions of witnesses there are always some normal discrepancies however honest and truthful the witnesses may be. These discrepancies are due to normal errors of observation	 normal errors of memory due to lapse of time	 due to mental disposition such as shock and horror at the time of the occurrence	 and the like. There are no material discrepancies in the evidence of P.W. 1 so as to reject the evidence in its entirety. [507 D E] 3. "Related" is not equivalent to "interested". A witness may be called "interested" only when he or she derives some benefit from the result of a 505 litigation; in the decree in a civil case	 or in seeing an accused person punished. A witness who is a natural one and is the only possible eye witness in the circumstances of a case cannot be said to be "interested". In the instant case. P.W. 1 had no interest in protecting the real culprit	 and falsely implicating the respondents. [507 A B]
