Summarize the following court judgment. iminal Appeals Nos. 159 and 160 of 1965. Appeals by special leave from the judgment and order dated July 28	 1965 of the Patna High Court in Criminal Appeal Nos. 533 and 534 of 1963. R. K. Garg	 D. P. Singh	 section C. Agarwala	 section P. Singh and K.M. K. Nair	 for the appellants (in both the appeals). B. P. Jha	 for the respondent (in both the appeals.) The Judgment of the Court was delivered by Hegde	 J. In these connected appeals by special leave the legality of the convictions of the appellants appellant Mohar Rai under section 324 of the Indian Penal Code and appellant Bharath Rai under section 324/109 of the Indian Penal Code is challenged. In the trial court the former was convicted under section 307 of the Indian Penal Code and the latter under section 307/109 of the Indian Penal Code. The High Court of Patna	 in appeal	 altered their convictions as set out above. In order to appreciate the contentions advanced on behalf of the appellants	 it is necessary to state briefly the prosecution as 527 well as the defence version. The case made out by the prosecution is that because of previous enmity Mohar Rai shot and injured P.W. I Balli Ahir	 at the instigation of Bharath Rai		 on the evening of October 8	 1961	 in Natwar Bazar. The existence of enmity between the appellants and most of the prosecution witnesses who speak to the occurrence	 is satisfactorily established. Many of the prosecution witnesses appear to have been proceeded against under section 107 of the Code of Criminal Procedure at the instance of the appellants. The plea of the appellants was that on the day of incident when they were returning to their house in the evening they were way laid by P.W.1 and several others; one of those persons fired shots at Mohar Rai	 but it missed him; to save himself he (Mohar Rai) ran away from the scene	 subsequently two more shots were fired; meanwhile he got into the house of Lal Bahadur Mistri (P.W.9)	 but his assailants pursued him	 forced their entry into the house of P.W.9 and there assaulted him; thereafter with a view to foist a false case against him forcibly thrust into his hands the revolver (Ex II) and then handed him over with exhibit III to Janardan Singh (P.W. 15)	 the police constable. ThE plea of Bharath Rai was that during the incident mentioned by Mohar Rai	 he was caught hold of and assaulted by some of the prosecution witnesses. The High Court and the trial court have rejected the plea of the appellants and relying on the prosecution evidence convicted the appellants as mentioned earlier. This Court being a Court of special jurisdiction does not reassess the evidence in a case except under exceptional circumstances. It was urged on behalf of the appellants that they did not have a fair trial	 the High Court as well as the trial court on an erroneous view of the law refused to take into consideration their defence	 they ignored important circumstances appearing in their favour and further some of the conclusions reached by them are unsupported by any evidence on record. We have to see how far these submissions are well founded. Out of the incident mentioned above	 the State came to ini tiate as many as three prosecutions. G. R. Case 1370/TR 20 of 61/63 in the Court Of the Munsif Magistrate I Class	 Sasaram was instituted on the basis of the complaint lodged by Mohar Rai. G.R. 506 of 1962 on the file of the Munsif Magistrate I Class	 Sasaram was a case under section 19(f) of the Indian Arms Act against Mohar Rai for being armed with a revolver at the time of the incident mentioned earlier. The third case is the one with which we are concerned in these appeals. The case instituted on the basis of the complaint made by Mohar Rai was acquitted on February 1	 1963. The Arms Act case ended in acquittal on May 13	 1964. The appeal against that order was dismissed by the High Court of Patna on September 5	 1966. A copy of the judgment in that appeal was produced at the hearing of these 528 appeals and received as additional evidence with our permis sion. The trial court as well as the High Court refused to examine the defence of the appellants solely on the ground that the case pleaded by them had been rejected by the learned Munsif Magistrate I Class	 Sasaram in the prosecution commenced at the instance of Mohar Rai. The prosecution case was that immediately after the occur rence	 Mohar Rai was chased and caught and at that time he had in his hands the revolver (Ex.III). Very soon thereafter he was produced before Audeshwar Prasad Singh (P.W.19) with the revolver in question. The further case of the prosecution was that P.W. 19 seized that revolver; later during investigation he seized the three cartridges said to have been fired by Mohar Rai as well as a misfired cartridge; the revolver as well as the seized cartridges were sent to the ballistic expert for examination. These facts were spoken to by the prosecution witnesses	 in particular by P.W. Janardhan Singh	 the constable to whom Mohar Rai was handed over immediately after the occurrence and P.W. 19 the investigating officer. P.W. 19 deposed that the number of the revolver seized is 545465. He is positive that the revolver seized from Mohar Rai is exhibit 111	 though in his report to the ballistic expert he had given the number of the revolver sent for examination as 545466	 but in that report itself he had added a note to say that the last two digits were not clear	. The prosecution proceeded on the basis there is no ambiguity about it that exhibit III was the weapon that was used in the commission of the offen ce. The ballistic expert who was examined as D.W. 1 was positive that the seized empties as well	 as the misfired cartridge could not have been fired from EX.III. The evidence of this witness has been accepted both by the trial court as well as by the High Court. From that it follows that the prosecution case that Mohar Rai fired three shots from exhibit III cannot be accepted as true. If this part of the prosecution case fails then very little remains in the prosecution case. The trial court and the High Court have brushed aside this important aspect on a wholly untenable basis. They opined that by some mistake a revolver different from that seized from Mohar Rai might have been sent to the ballistic expert. The conclusion has no basis on the material on record. It is just a speculation a process not open to courts. Evidently overwhelmed by the evidence of the large number of )Witnesses who deposed in favour of the prosecution case	 forgetting the fact that most of them belong to the faction opposed to the appel lants. the trial court and the High Court ignored the probabilities and lost sight of the evidence afforded by the circumstances appearing in the case. Both those courts failed to realise that the fact that exhibit III was not the revolver that was used during the 529 incident went to probablise the plea taken by Mohar Rai. At this stage we may recall the fact that both the trial Magistrate as well as the High Court rejected the prosecution case and acquitted Mohar Rai in the case against him under section 19(f) of the Arms Act. It is true that the decision of the trial court in that case was rendered after the Assistant Sessions Judge	 Sasaram	 convicted the appellants in the present case and therefore it may be that the appellants cannot take the benefit of the rule laid down by this Court in Pritam Singh vs The State of Punjab(1) and affirmed in Manipur Administration vs Thokchom	 Bira Singh(2). But even without the assistance of that rule	 on the basis of the prosecution evidence itself the prosecution version stands discredited. Once it is proved that the empties recovered from the scene could not have been fired from exhibit III the prosecution case that those empties were fired from exhibit III by Mohar Rai stands falsified. The trial court as well as the High Court wholly ignored the significance of the injuries found on the appellants. Mohar Rai had sustained as many as 13 injuries and Bharath Rai 14. We get it from the evidence of P.W. 15 that he noticed injuries on the person of Mohar Rai when he was produced before him immediately after the occurrence. Therefore the version of the appellants that they sustained injuries at the time of the occurrence is highly probabilised. Under these circumstances the prosecution had a duty to explain those injuries. The evidence of Dr. Bishun Prasad Sinha (P.W. 18) clearly shows that those injuries could not have been self inflicted and further	 according to him	 it was most unlikely that they would have been caused at the instance of the appellants themselves. Under these circumstances we are unable to agree with the High Court that the prosecution had no duty to offer any explanation as regards those injuries. In our judgment the failure of the prosecution to offer any explanation in that regard shows that evidence of the prosecution witnesses relating to the incident is not true or at any rate not wholly true. Further those injuries probabilise the plea taken by the appellants. Both the trial court as well as the High Court refused to take into consideration the plea of the appellants on the ground that that plea did not commend itself to the trial Magistrate in the case instituted on the complaint of Mohar Rai. They were erroneously of the view that the plea in question was barred by the rule laid down by this Court in Pritam Singh 's case(1). In that case	 this Court accepted as correct the following statement of (1) A.I.R. 1956 S.C. 415. (2) ; 530 the law made by the Judicial Committee in Sambasivam vs Public Prosecutor	 Federation of Malaya(): "The effect of a verdict of acquittal pronounced by a competent court on a lawful charge and after a lawful trial is not completely stated by saying that the person acquitted cannot be tried again for the same offence. To that it must be added that the verdict is binding and conclusive in all subsequent proceedings between the parties to the adjudication. The maxim 'res judicata pro vetitate accipitur ' is no less applicable to criminal than to civil proceedings. Here	 the appellant having been acquitted at the first trial on the charge of having ammunition in his possession	 the prosecution was bound to accept the correctness of that verdict and was precluded from taking any step to challenge it at the second trial. " Dixon J.	 of the Australian High Court in the King vs Wilkes(2) explained the legal position in these words : "Whilst there is not a great deal of authority upon the subject	 it appears to me that there is nothing wrong in the view that there is an issue estoppel	 if it appears by record of itself or as explained by proper evidence	 that the same point was determined in favour of a prisoner in a previous criminal trial which is brought in issue on a second criminal trial of the same prisoner. That seems to be implied in the language used by Wright	 J. in R. vs Ollis [1960] II Q.B. 758	 at p. 769) which	 in effect I	 have adapted in the fore going statement. There must be a prior proceeding determined against the Crown necessarily involving an issue which again arises in a subsequent proceeding by the Crown against the same prisoner. The allegation of the Crown in the subsequent proceeding must itself be inconsistent with the acquittal of the prisoner in the previous proceeding. But if such a condition of affairs arises I see no reason why the ordinary rules of issue estoppel should not apply. Such rules are not to be confused with those of res judicata	 which in criminal proceedings are expressed in the pleas of autrefois acquit and autrefois convict. They are pleas which are concerned with the judicial determination of an alleged criminal liability and in the case of conviction with the substitution of a new liability. Issue estoppel is concerned with the judicial establishment of a pro (1) (2) (77)C.L.R.511	 at pp.518 519. 531 position of a law or fact between parties. It depends upon well known doctrines which control the relitigation of issues which are settled by prior litigation." This Court endorsed that statement in Manipur Administra tion 's case( '). But the law laid down in those cases has no application to the facts of the present case. In both the prosecution in the complaint made by Mohar Rai as well as in tie complaint made by P.W. the prosecutor before the court was the State. Therefore	 the decision in the former case cannot operate as an issue estoppel against the appellants in the present case	 because they were not parties in the former case. In other words the plea taken by the appellants in this case was never before litigated between them and the State	 the opposite party in the present case. All that can be said is that the case put forward by the State in the one case is inconsistent with that put forward by it in the other. In those circumstances it was wrong to hold that the appellants were estopped from putting forward their defence. That apart	 it is doubtful though for the purpose of this case it is unnecessary to express any final opinion on this point whether the rule in question could be pressed against an accused	 the reason being that while a prosecution cannot succeed unless it proved its case beyond reasonable doubt	 the nature of the proof required of an accused in substantiating the plea taken by him is different it is sufficient if he proves that plea taken by him is reasonable and probable. In that event he is entitled to the benefit of doubt. This aspect was noticed by this Court in Manipur Administration 's(1) case	 where it was observed: "Before parting	 we think it proper to make one observation. The question has sometimes been mooted as to whether the same principle of issue estoppel could be raised against an accused	 the argument against its application being that the prosecution cannot succeed unless it proved to the satisfaction of the Court trying the accused by evidence led before it that he is guilty of the offence charged. We prefer to express no opinion on this question since it does not arise for examination. " For the reasons mentioned above	 we are satisfied that the trial court as well as the High Court erred in summarily rejecting the defence of the appellants on the sole ground that the version put forward by them having been rejected by the court in G.R. case 13761TR 20 of 61/63 in the court of the Munsif Magistrate I Class	 Sasaram the same cannot be again considered. We think that the defence of the appellants is highly probabilised by (1) ; 532 three important circumstances	 namely (i) the same was put forward immediately after the occurrence	 (ii) it satisfactorily explains the injuries found on the persons	 of the appellants while the prosecution evidence fails to explain those injuries	. and (iii) the prosecution evidence itself shows that Mohar Rai could not have used exhibit III and therefore his version that that weapon was thrust on him is probablised. The last contention taken by Mr. Garg is that admission of exhibit 4	 an inadmissible document	 has greatly prejudiced the case of the appellants. According to him	 the admission of that document is hit by section 162 of the Code of Criminal Procedure. In the alternative	 he contended that that document could not have been used to discredit the plea taken by Mohar Rai		 We have earlier noted the two divergent versions given by P.W.1 and Mohar Rai in respect of the incident that took place on the evening of October 8	 1961. Quite naturally	 both these complaints were investigated simultaneously. The statement given by P.W.1 was recorded as first information in one case and the statement given by Mohar Rai as first information in the other. Appellant Bharath Rai was questioned during the investigation. His statement is exhibit 4. The trial court came to the conclusion that it was not hit by section 162 as the same was not recorded in the course of investigation in the case against Bharath Rai. The High Court justified the admission of that document on the basis of the rule laid down by this Court in Faddi V. State of Madhya Pradesh( ')	 namely where the person who lodged the first information report regarding one offence is himself subsequently accused of that offence and tried and the report lodged by him is not a confessional first information report but is an admission by him of certain facts which have a bearing on the question to be determined by the Court	 viz.	 how and by whom the offence was committed or whether the statement of the accused in the court denying the correctness of certain statements of the prosecution witnesses is correct or not	 the first information report is admissible to prove against him	 his admissions which are relevant under section 21 of the Evidence Act. It was contended on behalf of the appellants that whether that statement is held to have been taken during the investigation of the complaint made by P.W. 1 or during the investigation of the complaint made by Mohar Rai	 in either case it is hit by section 162 of the Code of Criminal Procedure '. It was also urged that the rule laid down in Faddi 's case() has no application to the facts of the present case	 In the instant case no portion of exhibit 4 was relied on as an admission of Bharath Rai. Hence the rule laid down in Faddi 's case( ') could not have been called into aid. The trial court and the High Court relied on Bharath Rai 's statement that it was Naulakh Rai who fired a pistol (1) ; 523 to contradict the statement of Mohar Rai in his complaint that a pistol was fired by Dudhnath. No portion of exhibit 4 could have been used for that purpose either under section 157 or section 145 of the Evidence	 Act. As Bharath Rai was not examined as a witness in the present case his previous statement could not have been used either to contradict his evidence or corroborate it even if it is to be held that it is a statement coming under section 154 of the Code of Criminal Procedure : see Nazir Ali vs State of U.P.(1). The circumstances noticed above	 in our opinion	 not merely affect the value and weight to be attached to the prosecution evidence	 but they persuade us to doubt the prosecution version. In the circumstances	 we are unable to resist the conclusion that there has been a miscarriage of justice. We accordingly allow these appeals and acquit the appellants. Their bail bonds do stand cancelled. R.K.P.S. Appeals allowed. (1) A.I.R. 1957 S.C. 366.

The first appellant was convicted under.s. 324 IPC for shooting and injuring PW 1	 at the instigation of the second appellant	 who was himself convicted of an offence under section 324 read with section 109 IPC. The existence of enmity between the appellants and most of the prosecution witnesses who spoke to the occurrence was satisfactorily established. The plea of the appellants in their defence was that on the date of the incident when they were returning home in the evening	 they were way laid by PWI and several others and were assaulted; thereafter with a view to foist a false case against them	 a revolver was forcibly thrust into the hands of the first appellant. In connection with this incident	 the State came to initiate three prosecutions : One case was instituted on the basis of a complaint by the first appellant; a second case was commenced against the first appellant under section 19(f) of the Indian Arms Act for being armed with a revolver; and the third was the present case. The case instituted on the first appellant 's complaint as well as the case against him under the Arms Act were both dismissed. The trial court as well as the High Court refused to examine the defence of the appellants solely on the ground that the case pleaded by them had been rejected by the Magistrate in the prosecution commenced on these basis of the complaint by the first appellant. In appeal to this Court it was contended on behalf of the appellants that they did not have a fair trial; the High Court as well as the trial court on an erroneous view of the law refused to take their defence into consideration; they ignored important circumstances appearing in favour of the appellants; and furthermore	 some of the conclusions reached by them were unsupported by any evidence on record. It was also contended that an inadmissible document	 namely a statement made by	 the 'second appellant in the course of the investigation was wrongly admitted; this admission was hit by a. 162 of the Code of Criminal Procedure which bad also greatly prejudiced the case of the appellants. HELD : The appeals must be allowed and the appellants acquitted. (i) The trial court as well as the High Court erred in summarily ejecting the defence of the appellants on the sole ground that the version put forward by them having been rejected by the Magistrate in the case filed on the complaint of the first appellant	 it could not be considered again. The defence of the appellants was highly Probabilised by three important circumstances	 namely	 (1) it was put forward immediately after the occurrence	 (2) it satisfactorily explained the injuries found on the persons of the appellants while the prosecution evidence failed to 526 explain those injuries; and (3) the prosecution evidence itself showed that the first appellant could not have used the revolver exhibited and therefore his version that weapon was thrust on him was probabilised. [531 H 532 B] In both the prosecutions in the complaint made by the first appellant as well as in the complaint made by P.W.I the prosecutor before the court was the State. Therefore	 the decision in the former case could not operate as an issue estoppel against the appellants in the present case	 because they were not parties in the former case. In other words	 the plea taken by the appellants in this case was never before litigated between them and the State	 the Opposite party in the present case. All that ran be said is that the case put forward by the State in the one case was in consistent with that put forward by it in the other. In those circumstances it was wrong to hold that the appellants were estopped from putting forward their defence. 1531 B D] Pritam Singh vs The State of Punjab	 A.I.R. 1956 S.C. 415; Manipur Administration vs Thokchom	 Bira Singh	 (1964] S.C.R. 123; Sambasivam vs Public Prosecutor	 ; and King vs Wilkes; ; at pp. 518 519	 referred to. (ii) The trial court and the High Court relied on the second appellant 's statement in the document admitted in evidence to the effect that it was a particular person who fired a pistol to contradict the statement of the first appellant in his complaint that a pistol was fired by some other person. No portionof this statement could have been used for that purpose either section 157 ors. 145 of the Evidence Act. As the second appellant was not examined as a witness in the present case	 his previous statement could not have been used either to contradict his evidence or corroborate it even if it were to be held that it was a statement falling under s.154 of the Code of Criminal Procedure.
