Summarize the following court judgment. Appeal No. 2339 of 1968. (Appeal by Special Leave fro.m the Judgment and Order dated the 27 3 1968 of the Allahabad High Court in Second Appeal No. 2352 of 1963). G.N. Dikshit	 and O.P. Rana	 for the appellant. E.C. Agrawala	 for the respondent. The Judgment of the Court was delivered by SHINGHAAL	 J. Respondent Nawab Hussain was a confirmed SUbInspector of Police in Uttar Pradesh. An anonymous complaint was made against him and was investigated by Inspector Suraj Singh who submitted his report to the Super intendent of Police on February 25	 1954. Two cases were registered against him under the Prevention of Corruption Act and the Penal Code. They were also investigated by Inspector Suraj Singh	 and the respondent was dismissed from service by an order of the Deputy Inspector General of Police dated December 20	1954. He filed an appeal	 but it was dismissed on April 17	 1956. He; then filed a writ petition in the Allahabad High Court for quashing the disci plinary proceedings on the ground that he was not afforded a reasonable opportunity to meet the allegations against him and the action taken against him was mala fide. It was dismissed on October 30	 1959	 ' The respondent then filed a suit in the court of Civil Judge	 Etah	 on January 7	 1960	 in which he challenged the order of his dismissal on the ground	 inter alia	 that he had been appointed by the Inspector General of Police and that the Deputy Inspector General of Police was not competent to. dismiss him by virtue of the provisions of article 311 (1) of the Constitu tion. The State of Uttar Pradesh traversed the claim in the. suit on several grounds	 including ' the plea that the suit was barred by res judicata as "all the matters in issue in this case had been raised or ought to have been raised both 430 in the writ petition and special appeal. " The trial court dismissed the suit on July 21	 1960	 mainly on the ground that the Deputy Inspector General of Police would be deemed to be the plaintiffs appointing authority. It however held that the suit was not barred by the principle of res judica ta. The District Judge upheld the trial court 's judgment and dismissed the appeal on February 15	 1963. The respond ent preferred a second appeal which has been allowed by the impugned judgment of the High Court dated March 27	 1968	 and the suit has been decreed. The appellant State of Uttar Pradesh has therefore come up in appeal to this Court by special leave. The High Court has taken the view that the suit was not barred by the principle of constructive res judicata and that the respondent could not be dismissed by an order of the Deputy Inspector General of Police .as he had been appointed by the Inspector General of Police. As we have reached the conclusion that the High Court committed an error of law in deciding the objection regarding the bar of res judicata	 it will 	 not be necessary for us to examine the other point. The principle of estoppel per rem judicatam is a rule of evidence. As has been stated in Marginson vs Blackburn Borough council	(1) it may be said to be "the broader rule of evidence which prohibits the reassertion of a cause of action." This doctrine is based on two theories: (i) the finality and conclusiveness of judicial decisions for the final termination of disputes in the general interest of the community as a matter of public policy	 and (ii) the inter est of the indidual that he should be protected from multi plication of litigation. It therefore serves not only a public but also a private purpose by obstructing the reopen ing of matters which have once been adjudicated upon. It is thus not permissible to obtain a second judgment for the same civil relief .on the same cause of action	 for other wise the spirit of contentiousness may give rise to con flicting judgments of equal authority	 lead to multiplicity of actions and bring the administration of justice into disrepute. It is the cause of action which gives rise to an action	 and that is why it is necessary for the courts to recognise that a cause of action which results in a judgment must lose its identity and vitality. and merge in the judg ment when pronounced. It cannot therefore survive the judgment	 or give rise to another cause of action on the same facts. This is what is known as the general principle of res iudicata. But it may be that the same set of facts may give rise to two or more causes of action. If in such a case a person is allowed to choose and sue upon one cause of action at one time and to reserve the other for subsequent litigation	 that would aggravate the burden of litigation. Courts have therefore treated such a course of action as an abuse of its process and Somervell L.J.	 has answered it as follows in Greenhalgh vs Mallard(2) . "I think that on the authorities to which I will refer it would be accurate to say that res judicata for this purpose is (1) at p. 437. (2) at p	 257. 431 not confined to the issues which the court is actually asked to decide	 but that it covers issues or facts which are so clearly part of the subject matter of the litigation and so clearly could; have been raised that it would be an abuse of the process of the court to allow a new proceeding to be started in re spect of them. " This is therefore another and an equally necessary and efficacious aspect of the same principle	 for it helps in raising the bar of res judicata 	by suitably construing the general principle of subduing a cantankerous litigant. That is why this other rule has .sometimes been referred to as constructive res judicata which	 in reality	 is an aspect or amplification of the general principle. These simple but efficacious rules of evidence have been recognised for long	 and it will be enough to refer ' to this Courts decision in Gulabchand Chhotalal Parikh vs State of Bombay(1) for the genesis of the doctrine and its develop ment over the years culminating in the present section 11 of the Code of Civil Procedure	 1908. The section	 with its six explanations	 covers almost the whole field	 and has admirably served the purpose of the doctrine. But it relates to suits and former suits	 and has	 in terms	 no direct application to a petition for the issue of a high preroga tive writ. The general principles of res judicata and 	constructive res judicata have however been acted upon in cases of renewed applications for a writ. Reference in this connection may be made to Ex Parte Thompson(2). There A.J. Stephens moved for a rule calling upon the authorities concerned to show cause why a mandamus should not issue. He obtained a rule nisi	 but it was discharged as it did not appear that there had been a demand and a refusal. He applied again saying that there had been a demand and a refusal since then. Lord Denman C.J.	 observed that is Stephens was making an application which had already 'been refused	 on fresh materials	 he could not have "the Same application repeated from time to time" as they had "often refused rules" on that ground. The same view has been taken in England in respect of renewed petition for certiorari	 quo warranto and prohibition	 and	 as we shall show	 that is also the position in this country. We find that the High Court in this case 'took note of the decisions this Court in L. Janakimma lyer and others vs P. M. Nilakanta lyer and others(3)	 Devilal Modi vs Sales Tax Officer	 Ratlam and others(4) and Gulabchand Chhotalal Parikh vs State of Bombay (supra) and reached the following conclusion : "On a consideration of the law as laid down by the Supreme Court in 	the above three eases I am inclined to. agree with the alter native argument of Sri K.C. Saxena	 learn (1) ; (2) 6 Q.B. 720. (3) [1962] Supp. 1 S.C.R. 206. (4) ; 432 ed counsel for the plaintiff appellant	 that the law as declared by the Supreme Court in regard to the plea of res judicata barring a subsequent suit on the ground of dismissal of a. prior writ petition under Article 226 of the Constitution is that only that issue between the parties will be res judicata which was raised in the earlier writ petition and was decided. by the High Court after contest. Since no plea questioning the validity of the dismissal order based on the incompetence. of the Deputy Inspector General of Police was raised in the earlier writ petition filed by the plaintiff in the High Court: under Article 226 of the Constitution and the parties were never at issue on it and the High Court never considered or ' decided it. I think it is competent for the plaintiff to raise such a plea in the subsequent 'suit and bar of res judicata will not apply. " We have gone through these cases. Janakirama lyer 's was a case where the suit which was brought by defendants 1 to 6 was withdrawn during the pendency of the appeal in the High Court and was dismissed. In the mean time a suit was filed 'in a representative capacity under Order 1 rule 8 C.P.C. One of the defences there was the plea of res judicata. The suit was decreed. Appeals were filed against the decree	 but the High Court dismissed them on the ground that there was no bar of res judicata When the matter came to this Court it was "fairly conceded" that" in terms section 11 of the Code of Civil Procedure could not apply because the suit was filed by the creditors defendants 1 to 6 in their repre sentative character and was conducted as a representative suit	 and it could not be said that defendants 1 to 6 who were plaintiffs in the earlier suit and the creditors who had brought the subsequent suit were the same parties or parties who claimed through each other. It was accordingly held that where section 11 was thus inapplicable	 ' it would not be permissible to rely upon the general doctrine of res judicata	 as the only ground on which res judicata could be urged in a suit could be the provisions of section 11 and no other. That was therefore quite a different case ' and the High Court failed to appreciate that it had no bearing on the present controversy. The High Court then proceeded to consider this Court 's decisions in Devilal Modi 's case (supra) and Gulabchand 's case (supra). Gulabchand 's was the later of these two cases. The High Court has interpreted it to mean as follows : "It was held that the decision of the High Court on a writ petition under Article 226 on the merits on a matter after contest will operate as res judicata in a subse quent regular suit between the same parties with respect to the same matter. As appears from the report the above was majority view of the Court and the question whether the principles of constructive res judicata can be invoked by a party to the subsequent suit on the ground that a matter which might or ought to have been raised in the earlier proceedings was left open. The learned Judges took care to 433 observe that they made it clear that it was not necessary and they had not considered that the principles of constructive res judicata could be invoked by a party to the subse quent suit on the ground that a matter which might Or ought to have been raised in the earlier proceeding was not so raised therein. " As we shall show	 that was quite an erroneous view of the decision of this Court 	on the question of constructive res judicata. It will help in appreciating the view of this Court correctly if we make a brief reference to the. earli er ' decisions in Amalgamated Coalfields Ltd. and others vs Janapada Sabha	 Chhindwara(1) and Amalgamated Coalfields Ltd. and another vs Janapada Sabha	 Chhindwara	(2) which was also a case between the same parties. In the first of these cases a writ petition was filed to challenge the coal tax on some grounds. An ' effort was made to canvass an addi tional ground	 but that was not allowed by this Court and the writ petitton was dismissed. Another writ petition was filed to challenge the levy of the tax for the subsequent periods on grounds distinct and separate from those which were rejected by this Court. The High Court held that the writ petition was barred by res judicata 'because: of the earlier decision of this Court. The matter came up in appeal to this Court in the second case. The question which directly arose for decision was whether the principle of constructive res judicata was applicable to petitions under articles 32 and 226 of the Constitution and it was an swered as follows	 "It is significant that the attack against the validity of the notices in the present proceedings is based on grounds different and distinct from the grounds raised on the earlier occasion. It is not as if the same ground which was urged on the earlier occasion is placed before the Court in another form. The grounds now urged are entirely distinct	 and so	 the decision of the High Court can be upheld only if the principle of constructive res judicata can be said to apply to writ petitions filed under article 32 or article 226. In our opinion	 constructive res judica ta which is a special and artificial form of res judicata enacted by section 11 of the Civil Procedure Code should not generally be applied to writ petitions field under article 32 or article '226. We would be reluctant to apply this principle to the present appeals all the more because we are dealing with cases where the impungned tax liability is for different years. " It may thus appear that this Court rejected the application of the principle of constructive res judicata on the ground that it was a "special and artificial form of res judica ta" and should not generally be applied to writ petitions	 .but the matter did not rest there. It again arose for consideration in Devilal Modi 's case (supra). Gajendragadkar	 J. who had spoken for the court in the second case of Amalgamated Coalfields Ltd. spoke for the Court in that case also. The (1) ; (2) [1963]. Supp. 1. S.C.R. 172. 434 petitioner in that case was assessed to sales tax and filed a writ petition to challenge the assessment. The petition was dismissed by the High Court and he came in appeal to this Court. He sought to make some ' additional contentions in this Court	 but was not permitted to do so. He. there fore filed another writ petition in the High Court raising 	those ' additional contentions and challenged the order of assessment for the same year. The High Court dismissed the petition on merits	 and the case came up again to this Court in appeal. The question which specifically arose for consid eration was whether the principle of constructive res judicata was applicable to writ petitions of that kind. While observing that the rule of constructive res judicata was "in a sense a somewhat technical or artificial rule prescribed by the Code of Civil Procedure"	 this Court declared the law in the following terms	 "This rule postulates that if a plea could have been taken by a party in a proc ceding between him and his opponent	 he would not b0 permitted to take that plea against the same party in a subsequent proceeding which is based on the same cause of action; but basi cally	 even this view is founded on the same considerations of public policy	 because if the doctrine of constructive res judicata is not applied to writ proceedings	 it would be open. to the party to take one proceeding after another an urge new grounds every time; and that plainly is inconsistent with consid erations of public policy to which we have just referred. " While taking that view	 Gajendragadkar C.J.	 tried to ex plain earlier decision in Amalgamated Coalfields Ltd. vs Janapada Sabha	 Chhindwara(1) and categorically held that the principle of constructive res judicata was applicable to writ petitions also. As has been stated	 that case was brought to the notice of the High Court	 but its signifi cance appears to have been lost because of the decisions	 in Janakirama Iyer and others vs P.M. Nilakanta lyer (supra) and Gulabchand 's ease (supra). We have made a reference to the decision in Janakirama Iyer 's case which has no bearing on the ' present controversy	 and we may refer to the deci sion in Gulabchand 's case as well. That was a case where the question which specifically arose for consideration was whether a decision of the High Court on merits. on a certain matter after contest	 in a writ petition under article 226 of the Constitution	 operates as res judicata in a regular suit with respect to the same matter between the same par ties. After a consideration of the earlier decisions in England and in this country	 Raghubar Dayal J.	 who spoke for the majority of this Court	 observed as follows	 These decisions of the Privy Council well lay down that the provisions of section 11 C.P.C. are not exhaustive with respect to an earlier decision in a proceeding operating as res judicata in a subsequent suit with respect 	to the same matter inter parties	 and do not preclude the. application to regular suits of the general principles of res judicata based on public policy ' and applied .from ancient. times. " (1) [1963] Supp. 1 S.C.R. 172. 435 He made a reference to the decision in Daryao and others vs The State of U.P. and others(1) on the question of res judi cata and the decisions in Amalgamated Coalfields Ltd. and others vs Janapada Sabha	 Chhindwara(2) and Devilal Modi 's case (supra) and summarised the decision of the Court as follows : "As a result of the above discussion	 we are of opinion that the provisions of section 11 C.P.C. are not exhaustive with respect to an earlier decision operating as res judicata between the same parties on the same matter in controversy in a subsequent regular suit and that on the general principle of res judicata	 any previous decision on a matter in contro versy	 decided after full contest or after affording fair opportunity to the parties to prove their case by a Court competent to decide it	 will operate as res judicata in a subsequent regular suit. It is not necessary that the Court deciding the matter formerly be competent to decide the subsequent suit or that the former proceeding and the subsequent suit have the same subject matter. The nature of the former proceeding is immaterial. " He however went on to make the following further observa tion	 "We may make it clear that it was not necessary	 and we have not considered	 wheth er the principles of constructive res judicata can be invoked by a party to the subsequent suit on the ground that a matter which might or ought to have been raised in the earlier proceeding was not so	 raised therein. " It was this other observation which led the High Court to take the view that the question whether the principle of constructive res judicata could be invoked by a party to a subsequent suit on the ground that a plea which might or ought to have been raised in the earlier proceeding but was not so raised therein	 was left open. That in turn led the High Court to the conclusion that the principle of construc tive res judicata could not be made applicable to a writ petition	 and that was why it took the view that it was competent for the plaintiff in this case to. raise an additional plea in the suit even though it was available to him in the writ petition which was filed by him earlier but was not taken. As is obvious	 the High Court went wrong in taking that view because the law in regard to the applicability of the principle of constructive res judicata having been clearly laid down in the decision in Devilal Modi 's case (supra)	 .it was not necessary to reiterate it in Gulabchand 's case (supra) as it did not arise for consid eration there. The clarificatory observation of this Court in Gulabchand 's case (supra) was thus misunderstood by the High Court in observing that the matter had been "left open" ' by this Court. It is not in controversy before us that the respondent did not raise the plea	 in the writ petition which had been filed in the High Court	 that by virtue of clause (1) of article 311 of the Constitution he (1) ; (2) [1963] Supp. 1 S.C.R.172 436 could not be dismissed by the Deputy Inspector General of Police as he had been appointed by the Inspector General of Police. It is also not in controversy that that was an important plea which was within the knowledge of the re spondent and could well have been taken in the writ peti tion	 but he contented himself by raising the other pleas that he was not afforded a reasonable opportunity to meet the Case against him in the departmental inquiry and that the action taken against him was mala fide. It was there fore not permissible for him to challenge his dismissal	 in the subsequent suit	 on the other ground that 'he had been dismissed by an authority subordinate to that by which he was appointed. That was clearly barred by the principle constructive res judicata and the High Court erred in taking a contrary view. The appeal is allowed	 the impugned judgment of the High 'Court dated March 27	 1968	 is set aside and the respond ent 's suit is dismissed. In the circumstances of the case	 we direct that the parties shall pay and bear their own costs. P.B.R. Appeal allowed. 436SCI/77 2500 12 10 77 GIPF.

In a writ petition filed under article 226 of the Constitu tion impugning his dismissal from service	 the respondent contended that since he had not been given a reasonable opportunity of meeting the allegations against him	 his dismissal was void. writ petition was dismissed. Thereupon	 the respondent flied a suit in a civil court challenging his dismissal on the ground	 among others	 that since he had been appointed by the Inspector General of Po lice	 his dismissal by the Deputy Inspector General of Police was wrong. The State took the plea that the suit was barred by res judicata. Dismissing the suit	 the trial court held that it was not barred by res judicata. The first appellate court dismissed the respondent 's appeal. Purporting to follow a line of decisions of this Court	 the High Court held that only that issue between the parties would be res judicata which was raised in the earlier writ petition and was decided by the High Court after contest and since in this case the respondent did not raise in the earlier writ petition the plea of competence of the Deputy Inspector General of Police to dismiss him. the parties were never at issue on it and that the High Court never consid ered and decided this issue in the writ petition. On the question of invoking the principle of constructive res judicata by a party to the subsequent suit on the ground that the matter might or ought to have been raised in the earlier proceedings	 the High Court held that this question was left open by the Supreme Court in Gulabchand Chhotalal Parikh vs State of Bombay ; 	 and allowed the respondent 's appeal. Allowing the States appeal to this Court. HELD: The High Court was wrong in its view because the law in regard to the applicability of the principle of constructive res judicata having been clearly laid down in Devi Lal Modi vs Sales Tax Officer Ratlam and Others ; it was not necessary to reiterate it in Gulabchand 's case as it did not arise for consideration in that case. The clarificatory observation in Gulabchand 's case was misunderstood by the High Court in observing that the matter had been left open by this Court. The doctrine of res judicata is based on two theo ries: (i) the finality and conclusiveness of judicial deci sions for the final termination of disputes in the general interest of the community as a matter of public policy	 and (ii) the interest of the individual that he should be pro tected from multiplication of litigation. [430 D] 2. (a) In certain cases	 the same set of facts may give rise to two or more causes of action. In such cases res judicata is not confined to the issues which the Court is actually asked to decide but covers issues or facts which are so clearly part of the subject matter of the litigation and so clearly could have been raised that it would be an abuse of the process of the court to allow a new proceeding to be started in respect of them. This rule has sometimes been referred to as constructive res judicata which is an aspect or amplification of the general principle. [431 A] (b) Section 11 of the Code of Civil Procedure	 with its six explanations	 covers almost the whole field	 but the section has	 in terms	 no application to a petition for the issue of a high prerogative writ. [431 D] (c) Although in the Amalgamated Coalfields Ltd. and others vs Janapada Sabha	 ; this Court held that constructive res judicata being a special and artifi cial form of res judicata should not generally be applied to writ petitions	 in Devilat Modi 's this Court held that if the doctrine of constructive 429 res judicata was not applied to writ proceedings	 it would be open to a party to take one proceeding after another and urge new grounds every time	 which was plainly inconsistent with considerations of public policy. The principle of constructive res judicata was	 therefore	 held applicable to writ petitions as well. [433 G & 434 D] 3. The High Court missed the significance of these deci sions and relied upon L. Jankirama lyer and 'Others vs P.M. Nilakanta lyer and Others [1962] Supp. 1 S.C.R. 206 which had no bearing on the controversy. In Gulabchand 's case	 this Court observed that it did not consider it necessary to examine whether the principle of constructive res judicata could be invoked by a party to the subsequent suit oft the ground that a matter which might or ought to have been raised in the earlier proceeding but was not so raised therein could be raised again relying on which the High COurt concluded that the question was left open by this Court. This in turn led the High Court to hold that the principle of resjudicata could not be made applicable to a writ petition. [435 E F] In the instant case	 the respondent did not raise the plea that he could not be dismissed by the Deputy Inspector General of Police. This was an important plea which was within his knowledge and could well have been taken in the writ petition. Instead he raised the plea that he was not afforded a reasonable opportunity of meeting the case in the departmental inquiry. It was therefore not permissible for him to take in the subsequent suit the plea that he had been dismissed by an authority subordinate to that by which he was appointed. That was clearly barred by the principle of constructive res judicata and the High Court erred in taking a contrary view. [436 A B]
