Appeal by special leave from the judgment and order dated February 18	 1955	 of the Punjab High Court in Criminal Appeals Nos. 389 and 406 of 1954	 arising out of the judgment and order dated June 16	 1954	 of the Court of the Additional Sessions Judge	 Ferozepur	 in Sessions Case No. 5 of 1954 and Trial No. 5 of 1954. 726 Jai gopal Sethi	 Vidya Dhar Mahajan and K. L. Arora	 for the appellants. N.S. Bindra	 B. H. Dhebar and T. M. Sen	 for the respondent. December 4. The Judgment of the Court was delivered by SARKAR	 J. Eight persons were tried ::or offences under sections 148	 307 and 364 both read with sections 149 and 34 of the Indian Penal Code	 by the Additional Ses. sions Judge	 Ferozepur. The learned Sessions Judge acquitted four of the accused	 namely	 Het Ram	 Teja Ram	 Manphul and Surja Ram as he did not think that their presence at the occurrence had been proved beyond reasonable doubt. He convicted the remaining four	 namely	 Narain	 Jot Ram	 Gheru and Jalu under sections 307 and 364 read with section 34. He sentenced Narain	 Jot Ram and Gheru to rigorous imprisonment for three years under section 307 and two years under section 364. He sentenced Jalu to two years ' rigorous imprisonment under each section. On appeal by the convicted persons the High Court of Punjab maintained the convictions but reduced the sentences passed on Jot Ram and Gheru to one year 's rigorous imprisonment and Jalu to the term of imprisonment already undergone. It maintained the sentence passed on Narain and dismissed his appeal. Narain	 Jot Ram and Gheru have appealed To this Court from that judgment. The prosecution case is that one Sultan was the proprietor of a field described in the proceedings as plot No. 97. Sahi Ram had been a tenant of the land. The land had not been cultivated in the year preceding the occurrence with which this case is concerned and the owner had thereupon resumed possession of it. On June 14	 1953	 Mani Ram a son of the proprietor	 arrived at the field on a tractor accompanied by a Tabourer	 Moola Ram	 with the object of Ploughing it and found Sahi Ram actually ploughing. Mani Ram turned Sahi Ram out of the field. Sahi Ram raised a protest but eventually left abandoning his plough on the field. Mani Ram then began to plough the field 727 with his tractor. A little later the tractor developed mechanical trouble and Mani Ram stopped ploughing and started attending to it. While Mani Ram was so engaged	 Sahi Ram arrived at the spot accompanied by seven persons	 being the accused earlier named other than Narain	 variously armed. Jalu had come on a horse. They fell upon Mani Ram and assaulted him. Moola Ram who ran to his rescue was also assaulted. Moola Ram then attempted to run away whereupon Sahi Ram and his party chased him. While Sahi Ram and his party had their attention on Moola Ram	 Mani Ram got into his tractor and began to drive away from the field. At this point of time Narain arrived on a horse with a gun in his hand. He told the pursuers of Moola Ram to leave him as he was merely a hired man and pointed out that the real culprit Mani Ram was about to escape in the tractor. The party then turned round and pursued Mani Ram. Narain on his horse soon overtook Mani Ram and fired at him while he was still on the tractor in the driver 's seat. Mani Ram fell down from the tractor which	 being in motion	 proceeded on its own and ran into a tree and stopped. Narain 's horse fell against the cultivator of the tractor and was injured. Mani Ram picked himself up and staggered for shelter into the hut of one Mukh Ram	 which was nearby. The pursuers then came up and Jot Ram fired a shot at Mani Ram inside the hut and so did Gheru. Mani Ram fell down in the hut. Mukh Ram threw himself on the body of Mani Ram to protect him. Gheru and Narain then said that they would burn the hut with Mani Ram inside it. Sahi Ram suggested that it would be better to carry Mani Ram to their house and there kill him and burn his body. Mukh Ram 'was then dragged away and Mani Ram 's body was put on a horse and Jalu mounted it. The party then proceeded towards the village by a foot path with Mani Ram	 who was then unconscious	 as their captive. After they had gone some distance Raghbir	 the younger brother of Mani Ram	 having heard of the incident came to rescue Mani Ram. He met Jalu on the horse with Mani Ram and Sahi Ram walking close behind	 728 the rest of the party being at some distance. Raghbir asked Jalu to put down Mani Ram on which Jalu threatened to kill	 and Sahi. Ram pointed his sela at Raghbir. Raghbir then shot at Sahi Ram with the pistol he was carrying and the latter fell down and died soon after. Jalu got off the horse and ran away. Before the others could arrive Raghbir carried Mani Ram to the house of one Birbal from where he	 was later taken to the hospital. The defence was that the prosecution case was wholly false and the real facts were as follows: On the date of the occurrence Sahi Ram was ploughing the field when Mani Ram and Raghbir came there and tried to stop him. There was an altercation. Jot Ram and Gheru who were in a field nearby came up and advised Sahi Ram not to dispute over the matter with Mani Ram but have it decided by Panchayat. Sahi Ram	 Jot Ram and Gheru then left the field and proceeded towards the village. While going Jot Ram noticed that Sahi Ram was carrying a pistol and took it away from him to prevent him from using it in his excitement. Mani Ram and Raghbir also went towards the village but by a different route. The par. ties again met at the village Shamlat. Raghbir abused Sahi Ram and fired a shot at him killing him outright. Jot Ram apprehending that he might also be shot at	 fired the pistol which he had taken from Sahi Ram and might have injured Mani Ram. There were two unknown persons with Raghbir and Mani Ram at this time and they also used their fire arms. Mani Ram might have received injuries from these firings also. The accused denied that any of them except Jot Ram and Gheru were present at the incident. There were thus two conflicting versions of the same incident and there were two cross cases based on these separate versions. We are concerned with the case started on the complaint of Mani Ram and concerning the injuries suffered by him and his abduction. The other case was against Mani Ram	 Raghbir	 Sultan and Dalip also a son of Sultan and was based on what the defence version of the incident in the present case was. In that case Raghbir and Mani 729 Ram were charged under section 302 read with section 34 of the Indian Penal Code for having caused the death of Sahi Ram and Sultan and Dalip were charged under section 302 read with section 109 of the same Code in the same connection. The learned Sessions Judge who heard both the cases	 acquitted Mani Ram	 Raghbir	 Sultan and Dalip of the charges brought against them and convicted the appellants and Jalu in the present case accepting the prosecution version of the incident. As we have earlier stated	 the conviction was upheld by the High Court. In view of the concurrent findings of fact in the Courts below	 the learned Advocate for the appellants confined himself in this Court to a question of law which we now proceed to discuss. It has to be remembered that we are concerned only with the case in which the appellants had been tried for offences against Mani Ram. With the other case we are not concerned. In the trial Court	 the prosecution had cited Raghbir as a witness. Raghbir however refused to give evidence claiming protection under article 20 of the Constitution. The learned Sessions Judge held that Raghbir could not be compelled to give evidence and rejected the contention of the accused that he was not entitled to the protection. The prosecution in the end did not offer Raghbir as a witness and dropped him. When the matter came up before the High Court in appeal	 it was said on behalf of the appellants	 that the learned Sessions Judge was wrong in holding that Raghbir was entitled to the protection of article 20 and that the trial had been vitiated by this decision as a result of which the accused had been deprived of the benefit of Raghbir 's evidence. The High Court however held that the fact that Raghbir was not examined did not vitiate the trial in any way. It is this part of the High Court judgment that has been challenged before us by the learned Advocate for the appellants. The High Court observed as follows: " We may assume that Raghbir would 92 730 not have supported the prosecution story or that he would have admitted to having shot Sahi Ram. The fact that he was unwilling to make a statement does not constitute an irregularity in the trial. Had he been compelled to say something	 he would	 in all probability	 not have told the truth	 and the question is how the case would have been affected by his statement? In my view	 whatever he had stated would not have rebutted the convincing testimony of the other witnesses in the case and therefore the failure of the Court to examine him does not in any way affect the ultimate decision of the case. " The learned Advocate contended that the High Court had in view the provisions of section 167 of the Evidence Act though the section was not in terms referred. We think this is a fair view to take. The learned Advocate said that what the High Court has done is to say that even assuming that Raghbir 's evidence did not support the prosecution story	 that would not have made any difference to the result	 because	 what ever he stated would not have rebutted the convincing testimony of the other witnesses. According to the learned Advocate	 this view was not justified by section 167. It seems to us that the expression of the opinion of the High Court on this matter has not been happily worded. The question under section 167 is not so much whether the evidence rejected would not have been accepted against the other testimony on the record as whether that evidence " ought not to have varied the decision. " It is clear that if what Raghbir had said in his evidence had gone to support the defence version	 then a	 serious question would arise as to whether the decision of the trial Court would have been in favour of the accused instead of against them	 as it happened to be. It seems to us however that section 167 does not help the appellants. It is clear from the record that the prose cution	 though it had cited Raghbir as a witness	 was not very keen to examine him When Raghbir objected to give evidence	 the prosecution dropped him. Therefore it seems to us that this is not a case in which evidence can be said to have been rejected 731 within section 167 of the Evidence Act. The prosecution did not in fact tender Raghbir as a witness. Nor have we any idea as to what he would have said had he given evidence. Nor is it a case where the defence wanted to call him as a witness. It is not necessary for us	 nor have we been asked	 to decide the question whether Raghbir was entitled under article 2o of the Constitution to refuse to give evidence. It is amply clear from the record that the prosecution did not offer him as a witness upon his claiming protection under article 20. The learned Advocate for the appellants then argued that in this view of the matter	 it must be held that a material witness had been kept out of court by the prosecution and that would give rise to an adverse inference against the prosecution case and cast serious reflection on the fairness of the trial. We were referred by learned Advocate to Habeeb Mohammad vs The State of Hyderabad (1) in this connection. We agree that if a material witness has been deliberately or unfairly kept back	 then a serious reflection is cast on the propriety of the trial itself and the validity of the conviction resulting from it may be open to challenge	 The question then is	 was Raghbir a material witness ? It is an accepted rule as stated by the Judicial Committee in Stephen Seneviratne vs The King (2) that " witnesses essential to the unfolding of the narrative on which the prosecution is based	 must	 of course	 be called by the prosecution. " It will be seen that the test whether a witness is material for the present purpose is not whether he would have given evidence in support of the defence. The test is whether he is a witness " essential to the unfolding of the narrative on which the prosecution is based ". Whe ther a witness is so essential or not would depend on whether be could speak to any part of the prosecution case or whether the evidence led disclosed that he was so situated that he would have been able to give evidence of the facts on which the prosecution relied. It is not however that the prosecution is bound to call all witnesses who may have seen the occurrence and (1) ; (2) A.I.R. (1936) P.C. 289. 732 so duplicate the evidence. But apart from this	. the prosecution should call all material witnesses. Was Raghbir then a witness essential to the unfolding of the prosecution case ? That clearly Raghbir was not. The prosecution case	 as we have seen	 was concerned with the injuries caused to Mani Ram and his abduction. According to the prosecution case	 Raghbir arrived after these offences had been committed ; after Mani Ram had been assaulted and shot at and after he had been put on a horse and had been carried some distance. The prosecution no doubt admits that Raghbir shot Sahi Ram but says that he did so in self defence. This incident is an entirely separate incident. It is not necessary to prove it in order to prove the offences with which the appellants were charged. Raghbir therefore was not a witness whom the prosecution was bound to call to establish its case. The fact	 assuming it to have been so	 that Raghbir would have said in his evidence that the incidents did not happen as the prosecution stated	 may no doubt have established a good defence. But if it was so	 then he would have been only a witness material for the defence and not a witness essential to the unfolding of the narrative on which the prosecution case is based. The prosecution is not bound to call witnesses to establish the defence but only witnesses who are material for proving its own case. Indeed	 since according to the prosecution case Raghbir arrived after the alleged offences were committed	 he could not have given any evidence about the prosecution case. We	 therefore	 think that the contention of the learned Advocate for the Appellants that the prosecution should have called Raghbir to ensure a fair trial or that he was a witness material to the prosecution case	 is unfounded. We do not think that the trial has at all been vitiated by the failure to call Raghbir. It may be pointed out that the appellants had not sought to produce Raghbir as a witness on their behalf The learned Advocate then addressed us on the question of the sentence passed on Narain. He said that the High Court passed a higher sentence on him 733 because it was under the impression that he had caused the only grievous injury that was found on the body of Mani Ram. The learned Advocate pointed out that there was no evidence to show that the grievous injury had been caused by Narain. It seems to us that this contention is justified. There is however evidence to show that Narain merited the higher sentence. It was he who directed the attack against Mani Ram. He called the other members of the attacking party to desist from pursuing Moola Ram as Mani Ram was the real enemy and should be dealt with. It is upon that the serious injuries on Mani Ram came to be inflicted. We	 therefore	 think that the higher sentence imposed on the appellant Narain was justified. No other question arises in this appeal. The result is that the appeal fails and is dismissed. Appeal dismissed.

Several persons attacked and seriously injured one M. After assaulting him the assailants were carrying him away when M 's brother R came to rescue him and in self defence shot dead one of the assailants and carried M away. For the assault on M eight persons	 including the appellants	 were tried for offences under (1) C.B.N.S. 161; (1862)133 R.R. 311. 725 sections 148	 307 and 364 both read with sections 140 and 34 Of the Indian Penal Code. At the trial R was cited as a witness by the prosecution	 but R refused to give evidence claiming protection under article 20 Of the Constitution. The Sessions judge upheld R 's objection and the prosecution gave him up as a witness. After trial	 the Sessions judge acquitted four of the accused but convicted the appellants and one other person. In appeal before the High Court the appellants urged that the Sessions judge was wrong in holding that R was entitled to the protection of article 2o and that the trial was vitiated by this decision whereby the accused had been deprived of the benefit of R 's evidence. The High Court was of the view that if R had been compelled to give evidence he would not have supported the prosecution but whatever he would have stated would not have rebutted the convincing testimony of the other witnesses and that therefore the failure to examine R did not in any way affect the ultimate decision of the case. The High Court apparently had section 167 Of the Evidence Act in view. In the result the High Court upheld the convictions. The appellants appealed and contended that the view of the High Court was not justified by section 167 and that the trial was not fair as R	 a material witness	 had been kept out of Court. Held	 that the trial was not vitiated by the failure of the prosecution to examine R as a witness. Section 167 did not help the appellants as it was not a case in which evidence could be said to have been rejected within the meaning of that section. Further	 R was not a witness material to the prosecution inasmuch as he arrived on the scene after the assault was over and it was not necessary for the prosecution to examine him to ensure a fair trial. Where a material witness has been deliberately or unfairly kept back	 a serious reflection is cast on the propriety of the trial and the validity of the conviction resulting from it may be open to challenge. The test whether a witness is material is whether he is essential to the unfolding of the narrative on which the prosecution is based and not whether he would have given evidence in support of the defence.
