Summarize the following court judgment. Appeal No. 432 of 1963. Appeal from the Judgment and Decree dated the August 27	 1958 of Andhra Pradesh High Court in Appeal Suit No. 113 of 1954. C. Narasimhacharyya and K. R. Chaudhury	 for the appel lant. P. Ram Reddy	 for respondents Nos. 4 to 7. P. Ram Reddy and A. V. V. Nair	 for respondents Nos. 15	 16	 18 to 20	 22	 23 to 25. The Judgment of the Court was delivered by Shah J. Khader Miran	 Muhammad Abdul Kassim and Muhammad Labhai mortgaged on August 21	 1933	 certain immovable property in favour of Narsimha Reddy to secure repayment of Rs. 20	000/ . Khader Miran died on November 19	 1937. On July 12	 1940 Narsimha Reddy commenced an action for enforcement of the mortgage against Muhammad Abdul Kasim	 Muhammad Labhai	 and three widows of Khader Miran Fathima Bi	 Amina Bi and Mahaboob Bi	 and a daughter Muhammad Mariyam Bi. A preliminary mortgage decree passed in the action on November 25	 1940 was made absolute on October 11	 1941	 and in execution of the decree the properties mort 939 gaged were sold at a court auction and were purchased by the mortgagee Narsimha Reddy on October 16	 1942	 with leave of the Court. Narsimha Reddy thereafter transferred the properties to P. Chinnamma Reddi and the latter in his turn alienated portions thereof. N. K. Mohammad Sulaiman hereinafter referred to as 'the plaintiff ' claiming that he was the son of Khader Miran instituted suit No. 125 of 1950 in the Court of the Subordinate Judge	 Chittoor for a decree for partition of the mortaged properties by metes and bounds" and in the alternative for a declaration that he was entitled "to redeem the mortgage or portion thereof equal to his share in the mortgaged properties" and for an order against Narsimha Reddy and the alienees from him to render a true and correct account of the income of the properties	 and for a further declaration that the decree and judgment in suit No. 87 of 1940 and the execution proceedings thereon were null and void	 and "if necessary to set aside the same. " To this suit were impleaded Mahammad Ismail who	 it was claimed	 was also the ;on of Khader Miran	 and was not impleaded in the earlier suit	 Mahaboob Bi the mother of the plaintiff	 Mariyam Bi his step sister	 narsimha Reddy and twenty two alienees of the property. The suit was resisted by Narsimha Reddy and the alienees on two principal grounds that the plaintiff was not the son of Khader Miran	 and that the decree in suit No. 87 of 1940 was in any event binding upon the plaintiff for the estate of Khadar Miran was fully represented in the suit by those who were in possession of the estate of Khader Miran. On the second plea	 it was sub mitted that Narsimha Reddy had made "full and bona fide in quiry" and had come to learn that only the three widows and daughter of Khader Miran were the surviving members of the family of Khader Miran and that they were in possession of his estate	 and that it was not brought to the notice of Narsimha Reddy at any time that there were	 beside those impleaded	 other heirs to the estate of Khader Miran. The Trial Court held that the plaintiff who was the son of Khader Miran was "sufficiently represented" by the three widows and the daughter of Khader Miran in suit No. 87 of 1940	 and that the plaintiff and his brother Mohammed Ismail were bound by the decree and the sale in execution thereof	 even though they were not impleaded as parties eo nomine. In appeal to the High court of Andhra Pradesh	 the decree passed by the Trial Court	 dismissing the plaintiff 's suit was confirmed. With certificate 940 granted by the High Court	 this appeal is preferred in forma pauperis by the plaintiff. The Trial Court and the High Court have held that Narsimha Reddy had instituted the mortgage suit after making bona fide enquiry and being satisfied that the only heirs of Khader Miran were his three widows and his daughter	 and that the entire estate was in their possession	 and that there were no other heirs. This finding is not challenged before us	 but counsel for the plaintiff argues that when in a suit to enforce a mortgage instituted after the death of a Muslim debtor one or more out of the heirs of the deceased debtor is or are not impleaded in the suit and a decree is obtained	 what passes to the auction purchaser at the court sale is only the right	 title and interest in the properties of the heirs of the deceased debtor who were impleaded in the suit. On this question	 there has been a sharp conflict of opinion amongst the High Courts in India. It is necessary in the first instance to set out certain principles which are accepted as well settled. The estate of a muslim dying intestate devolves under the Islamic law upon his heirs at the moment of his death i.e. the estate vests immediately in each heir in proportion to the shares ordained by the personal law and the interest of each heir is separate and distirct. Each heir is under the personal law liable to satisfy the debts of the deceased only to the extent of the share of the debt proportionate to his share in the estate . A creditor of a muslim dying intestate may sue all the heirs of the deceased	 and where the estate of the deceased has not been distributed between the heirs	 he may execute the decree against the property as a whole without regard to the extent of the liability of the heirs inter se. The creditor is however not bound to sue all the heirs: the creditor may sue some only of the heirs and obtain a decree against those heirs	 and liability for satisfaction of the decree may be enforced against individual heirs in the property held by them proportionate to their share in the estate. It is also settled that where the defendant in an action dies after institution of the suit	 he creditor after diligent nd bona fide enquiry impleads some but not all the heirs as legal representatives	 the heirs so impleaded represent the estate of the deceased and a decree obtained against them binds not only those heirs who are impleaded in the action but the entire estate including the interest of those not brought on the record: Dava Ram and others vs Shyam Sundari & others(1) : This Court at p. 240 observed (1)[1965] 1 S.C.R. 231 941 .lm15 "The almost universal consensus of opinion of all the High Courts is that where a plaintiff or an appellant after diligent and bona fide enquiry ascertains who the legal representatives of a deceased defendant or respondent are and brings them on record within the time limited by law	 there is no abatement of the suit or appeal	 that the impleaded legal representatives sufficiently represent the estate of the deceased and that a decision obtained with them on record will bind not merely those impleaded but the entire estate including those not brought on record." This Court has therefore recognised the principle of representation of the estate by some heirs where the defendant dies during the pendency of a suit to enforce a claim against him	 and not all the heirs are brought on the record. If after bona fide enquiry	 some but not all the heirs of a deceased defendant are 'brought oil the record	 the heirs so brought on the record represent the entire state of the deceased	 and the decision of the Court in the absence of fraud or collusion binds those who are not brought on the record as well as those who are impleaded eo nomine. Daya Ram 's case	 it is true	 did not relate to the estate of a deceased Muslim	 but the rule enunciated is of the domain of procedural law and applies to all communities irrespective of the religious pursuasion or personal law. Counsel for the plaintiff says that this rule applies only to cases where the defendant dies after institution of the suit	 and does not apply where a suit is instituted against the heirs of a deceased debtor. The reason suggested is that by the combined operation of 0. 22 rr. 4 & 5 Code of Civil Procedure there is a decision of the Court that persons impleaded are the heirs of the deceased and are allowed to be brought on the record as his heirs and legal representatives. Reliance is also placed upon the definition of "legal representative" in section 2 (11 ) of the Code of Civil Procedure. It is submitted that where persons are either expressly or by implication directed or permitted by an order of the Court to represent the estate	 in the absence oil fraud or collusion the heirs brought on the record will represent the entire estate	 and the decree passed against them and proceedINGS taken pursuant thereto will be binding upon the heirs not so impleaded. But where the plaintiff institutes a suit against certain person as legal representatives of the deceased debtor there is no representation to the estate by some only of the heirs of the deceased where the deceased was a muslim. On this point there has been	 as already stated	 conflict of opinion and in some High Courts from time to time different views have been expressed To seek elucidation of principle from an analysis 942 of the numerous decisions of the cases may turn out a futile pursuit. That is not because we do not hold the opinions expressed by eminent Judges on this question in great respect	 but because in our view it would conduce to greater clarity if the grounds on which the decisions have proceeded are examined in the light of the true principles applicable. In seeking its solution the problem whether a decree obtain ed by a creditor in a suit instituted against some of the heirs of a deceased Muslim for payment of debts due by him is binding on the other heirs has been approached from different angles : (i) by the analogy of Hindu law where on devolution of property on death of a Hindu upon members of a joint Hindu family or a widow the estate of the deceased is represented by the manager or the widow	 and the creditor in a suit properly instituted against the manager or the widow may obtain a decree which binds all the persons having interest in the estate; (ii) the rule of Mahomedan law as set out in Hamilton 's Hedaya	 2nd Edn.	 p. 349	 Bk. XX	 Ch. 4 (relating to the duties of the Kazee): "for any one of the	 heirs of a deceased person stands as litigant on behalf of all the others	 with respect to anything due to or by the deceased	 whether it be debt or substance	 since the decree of the Kazi in such case is in reality either in favour of or against the deceased; and any of the heirs may stand as his representative with respect to such decree. . To this it is objected	 "If one heir be litigant on behalf of the others	 it would follow that each creditor is entitled to have recourse to him for payment of his demand	 whereas	 according to law	 each is only obliged to pay his own share. " Reply : "The creditors are entitled to have recourse to one of several heirs only in a case where all the effects are in the hands of that heir. This is what is stated in the Jama Kabeer; and the reason of it is that although any one of the heirs may act as plaintiff in a cause on behalf of the others	 yet he cannot act as defendant on their behalf	 unless the whole of the effects be in his possession"; (iii) that a creditor of the deceased may sue one of the heirs who is in possession of the whole or any part of the estate	 without joining other heirs as defendants	 for administration of the estate and for recovery of the entire debt	 and Pet a decree against the entire estate; and (iv) on the strict rules of Islamic law that devolution of inheritance takes place immediately upon the death of the ancestor	 and jus representations being foreign to the Islamic law of inheritance	 and only those heirs who are sued by the creditor of the deceased ancestor are liable to satisfy the debt proportionate to their interest in the estate. The first view was enunciated by the Calcutta High Court in Mussemut Nuzeerun vs Moulvie Amerooddin(1) and was adopted by the Bombay High Court in Khurshetbibi vs Kesho Vinayak(2; Davalava vs Bhimaji ( 3 ) and Virchand vs Kondu (4 ) . The second view though pressed for acceptance before the Courts has not met with approval. The rules of procedure enunciated by the Muhammadan lawyers have no application under the Indian system of jurisprudence to the trial of actions in our courts and as observed by Mahmood	 J.	 in Jafri Begam vs Amir Muhammad Khan(") at p. 842: " . and if there are any claims against the estate	 and they are litigated	 the matter passes into the region of procedure	 and must be regulated according to the law which governs the action of the Court	 The plaintiff must go to the Court having jurisdiction	 and institute his suit within limitation	 impleading all the heirs against whose shares he seeks to enforce his claim; " The Calcutta High Court in Muttyjan vs Ahmed Ally(") accepted the third view and regarded a suit filed by a creditor to recover a debt due from the estate of a deceased muslim debtor as an administration action. It was further confirmed in Amir Dulhin vs Baijnath Singh(7). On this rule an exception was engrafted in a later judgment in Abbas Naskar vs Chairman	 District Board	 24 Parganas(8). It was observed in Abbas Naskar 's case(") that in the case of an estate of a muslim dying intestate if there has been no distribution of the estate	 and the suit is instituted for recovery of a debt the creditor may sue any heir in possession of the whole or part of the estate without joining the other heirs as defendants	 for realisation of the entire debt passed in such a suit may be enforceable against all the assets that are in his possession. But a decree for administration may only be passed where the heirs who are sued are in possession of the whole or any part of the estate so as to be liable to account for the same to the rest	 or in other words	 the suits were against some of the heirs	 who are in possession of property exceeding their share of the inheritance: where the heirs are in possession of the respective shares of inheritance	 the principle can have no (1) (3) I.L.R. (5) I.L.R. 7 All. 822. (7) I.L.R. 1. (2) I.L.R. (4) I.L.R. (6) I.L.R. (8) I.L.R. 944 application. The modified rule accepted by the Calcutta High Court is that where a heir is in possession of the estate of a deceased muslim on behalf of the other heirs	 in a suit to recover a debt due from the estate a decree for administration may be passed. The last view has been uniformly expressed by the Allahabad High Court since it was first enunciated by Mahmood J.	 in Jafri Begam 's case(1). It may be observed that the Bombay High Court in later decisions has accepted this view : Bhagirthibai vs Roshanbi (2 ) : Shahasaheb vs Sadashiv(3): Lala Miya vs Manubibi (4 ) and Veerbhadrappa Shilwant vs Shekabai(5). We may now examine whether the grounds on which the different views were expressed are sustainable in principle. It must be recalled that whether a decree obtained by a creditor against the heirs of a deceased muslim is binding upon the entire estate or only of those who were impleaded eo nomine is not a question to be determined on the personal law either of the deceased or of the defendant in the suit. It is a part of the law of procedure which regulates all matters going to the remedy	 and when the matter passes into the domain of procedure	 it must be regulated by the law governing the action of the Court. An administration action may undoubtedly lie at the instance of a creditor for and on behalf of all the creditors for an order that the Court do enter upon administration of the estate and do pay to the creditors claiming the amount either the whole or such amount as may be rateably payable to each creditor out of the estate after satisfying the primary liabilities of the estate. A suit by a creditor may in appropriate cases	 where the procedure Prescribed in that behalf is followed	 be treated as an administration action	 but Very action instituted by a creditor of a deceased debtor to recover a debt due out of his estate in the hands of some or all the heirs is not an administration action. A person in possession of the whole or a part of the estate which originally belonged to a debtor dying intestate does not clothe himself with a right to represent other persons who are interested in the estate. Such a person may by intermeddling with the estate be regarded is executor de sontort and may render himself liable accordingly	 but thereby he cannot represent those whose estate he has intermeddled with. An administrator appointed by the Court would (1) I.L.R. 7 All.822 (2) I.L.R. (3) I.L.R. (4) I.L.R. (5) I.L.R. 945 resent the estate	 and a creditor may sue him for recovery of the debts due out of the estate. In an administration action properly instituted	 the Court may take upon itself the duty to administer the estate out of which the debts may be satisfied. But a simple action for recovery of a debt from the estate of a deceased debtor will not be regarded as an action for administration. Ordinarily the Court does not regard a decree binding upon a person who was not impleaded eo nomine in the action. But to that rule there are certain recognised exceptions. Where by the personal law governing the absent heir the heir impleaded represents his interest in the estate of the deceased. There is yet another exception which is evolved in the larger interest of administration of justice. If there be a debt justly due and no prejudice is shown to the absent heir	 the decree in an action where the plaintiff has after bona fide enquiry impleaded all the heirs known to him will ordinarily be held binding upon all persons interested in the estate. The Court will undoubtedly investigate	 if invited	 whether the decree was obtained by fraud	 collusion or other means intended to overreach the Court. The Court will also enquire whether there was a real contest in the suit	 and may for that purpose ascertain whether there was any special defence which the absent defendant could put forward	 but which was not put forward. Where however on account of a bona fide error	 the plaintiff seeking relief institutes his suit against a person who is not representing the estate of a deceased person against whom the plaintiff has a claim either at all or even partially	 in the absence of fraud or collusion or other ground which taint the decree	 a decree passed against the persons impleaded as heirs binds the estate	 even though other persons interested in the estate are not brought on the record. This principle applies to all parties irrespective of their religious persuation. A few illustrative cases which support this principle may be noticed. In Chaturbujadoss Kushaldoss and Sons vs Rajamanicka Mudali(1) a debtor died leaving a will bequeathing his estate to his nephew subject to certain dispositions. In ignorance of the will	 and bona fide believing that the widow was the proper legal representative	 a creditor of the deceased brought a suit against her alone and obtained a decree ex parts for satisfaction of the debt out of the husband 's estate and satisfied his claim by sale of certain items of the estate in her hands. A nephew of the deceased who was a devisee under the will sued to set aside the decree and sale in execution thereof. It was held by the High Court of (1) I.L.R. Sup. CI/65 17 946 Madras that as the creditor bona fide believed the widow was the proper legal representative and as she was then interested in defending the estate and sufficiently represented the estate and as the creditor got his decree without any fraud or collusion with her	 it was binding on the nephew who was the residuary legatee under the will. In dealing with this question	 Madhavan Nair	 J.	 observed at p. 218 : "Prima facie	 a decree will bind only the parties to it or those claiming through them; but there are exceptions to this rule. The Courts have held that in certain circumstances when one who is not the true legal repre sentative of a deceased person is impleaded as his legal representative	 then a decree passed against him in his character as the legal representative of the deceased would be binding on the true representative though he is not a party to it. The suit may have been instituted against the wrong legal representative at the very commencement or the wrong legal representative may have been brought on record during the pendency of the suit or after the decree and for purposes of execution. " The principle so stated derives support from the judgment of the Judicial Committee in Khairajmal vs Daim(1). In that case	 the material facts out of the many complicated facts which have a bearing on the point under review are these : a suit was instituted for redemption of two mortgages of 1874 in respect of certain immoveable properties. The plea of the mortagee in substance	 was that the equity of redemption had been sold in execution of money decrees against the mortgagors in earlier proceedings and was vested in other persons	 and therefore the mortgagors had no right to sue. One of such mortgagors was Nabibaksh. It appeared that in suit No. 372 of 1879 instituted for recovery of a debt there was reference to arbitration	 and Nabibaksh signed the reference. Nabibaksh died shortly thereafter and his two widows and his son Muhammad Hassan named as legal re presentivs were served with the summons and were willing to accept the award. They were also served with the notice of sale of the property of Nabibaksh. An infant daughter of Nabibaksh was omitted from the list of heirs impleaded	 but the entire interest of Nabibaksh was sold in execution of the decree obtained in that suit. The Judicial Committee held that the estate of Nabibaksh as sufficiently represented for the purpose of the suit	 although the name of the infant daughter was omitted and (1) L.R. 32 T.A. 23. 947 that the share of Nabibaksh in the equity of redemption in the property sold in execution of the decree in suit No. 372 of 1879 being bound by the sale	 was irredeemable. It is true that Nabibaksh died after the suit for recovery of the debt was instituted and his heirs were brought on the record under a procedure similar to O. 22 r. 4 of the Code of the Civil Procedure. But the Judicial Committee did not express the view that the estate was represented because the heirs were brought on record after the death of Nabibaksh in a pending suit	 but apparently on the principle on which the Madras High Court in Chaturbujadoss Kushaldoss & Sons ' case(1) proceeded. This view was also expressed by the High Court of Orissa in Sarat Chandra Deb and others vs Bichitrananda Sahu and others(2)	 where Jagannadhadas	 J.	 observed that where proceedings taken bona fide by the creditor against the person actually in possession by virtue of the assertions of a claim to succeed to or represent the estate of the deceased '; debtor are binding against the real legal heir	 whether such proceedings were commenced or continued against the wrong person	 and irrespective of any express or implied decision by the Court that the 	person so impleaded was the proper legal representative. The Court in that case recognised that though the title of a persons to property cannot normally be affected by any proceeding to which he is not a party	 his interest in the property may still be bound if he may having regard to the circumstances	 be said to	 have been sufficiently represented in the proceeding. The learned judge observed at p. 445: "I have	 therefore	 no hesitation in coming to the conclusion that where a mortgagee institutes a suit bona fide against the person in possession of the estate of the deceased mortgagor	 who is in such possession in assertion of a claim to succeed to that estate	 and where a person purchases the mortgaged property bona fide in execution of that decree	 such purchaser gets the full title to the mortgaged property by virtue of such sale and the real heir is bound thereby and that his only remedy	 if at all	 in a proper case is to get the sale set aside by appropriate proceedings in time." In a recent judgment of the Madras High Court in Shunmughom Chettiar vs K. A. Govindasami Chettiar and others(3) it was held that where after the death of the mortgagor	 in a suit on the mortgage	 the mortgagee bona fide and "after due care and ' (1) I.L.R. (2) I.L.R. [1950] Cutt. (3) A.I.R. 1961 Mad. 948 caution" impleads a person who is believed by him to be the legal representative of the mortgagor and who is in possession of the mortgaged property and a decree is obtained on that footing without the legal representative so impleaded disclaiming any liability	 the decree thus obtained by the mortgagee will bind other legal representatives who may be in existence. It is true that the cases of the Madras & Orissa High Courts did not relate to the estate of a muslim debtor. But the rule	 as already stated	 is one of procedure and not of personal law	 and applies to a muslim debtor 's estate as well as to a Hindu debtor 's estate. It is true that in the case of a debtor who is sued for recovery of the debt	 and if he died after the institution of the suit	 there is some order of the Court express or implied recognising that the person sought to be brought on record are the heirs and legal representatives of the deceased debtor. The Court records a conclusion	 if not expressly	 by implication	 that they :represent the estate. It was held by this Court	 as already stated 	earlier	 in a recent judgment in Daya Ram 's case(1) that failure ;to bring the other heirs on record	 if there is a bona fide enquiry :as to the existence of the heirs	 does not affect the validity of the decree and the proceedings taken thereunder. In a suit instituted against the heirs of a deceased debtor	 it is the creditor who takes upon himself the responsibility to bring certain persons as heirs and legal representatives of the deceased on the record. If he has proceeded bona fide and after due enquiry and under a belief that the persons who are brought on the record are the only legal representatives	 it would make no difference in principle that in the former case the heirs have been brought on the record during the pendency of the suit	 the creditor having died since the institution of the suit	 and in the other case at the instance of the plaintiff certain persons are impleaded as legal representatives of the deceased person. In either case	 where after due enquiry certain persons are impleaded after diligent and bona fide enquiry in the genuine belief that they are the only persons interested in the estate	 the whole estate of the deceased will be duly represented by the persons who are brought on the record or impleaded	 and the decree will be binding upon the entire estate. This rule will of course not apply to cases where there has been fraud or collusion between the creditor and the heir impleaded	 	or where there are other circumstances which indicate that there has not been a fair or real trial	 or that the absent heir had a special defence which was not and could not be tried in the earlier proceeding. (1) ; 949 The appellant and his brother Mohammad Ismail were both minors when the action for enforcement of the mortgage in favour of Narsimha Reddy was instituted. The mortgaged pro perty was in the possession of the three widows and daughter of Khader Miran	 and the other mortgagors. It is also found that Narsimha Reddy had made bona fide enquiry and had not come to learn about the existence of any other heirs. It is also not the case of the appellant that he had any special defence to the suit which if he was impleaded as a party to the suit he could have set up	 nor is there any ground for holding that there was no fair or real trial of the action. This appeal therefore fails and is dismissed with costs. The appellant was permitted to appeal in forma pauperism He will pay the court fee payable on the memo of appeal as if he had not been permitted to appeal in forma pauperis Appeal dismissed.

M	 K and L mortgaged certain immovable properties in favour of R in 1933. M died in 1937 and in 1940	 R commenced an action for enforcement of the mortgage against K	 L and three widows and a daughter of M. In execution of the decree passed in the action	 the properties were bold at a court auction in 1942 and purchased by R	 who thereafter trans ferred them to others. The appellant plaintiff	 claiming that he was the son of M	 instituted a suit in 1950 for a decree for partition of the mortgaged properties "by metes and bounds" and in the alternative for a declaration that he was entitled to redeem the mortgage or a portion thereof equal to his share in the mortgaged properties. The plaintiff 's suit was resisted by R and the other alienees of the properties	 mainly on the ground that the decree of 1940 was binding on the appellant for the estate of M was fully represented in the suit by those who were in possession at the time; and that R had made full and boan fide inquiry and had learnt that the three widows and the daughter of M were the only surviving members of the latter 's family. The trial court dismissed the appellants 's suit and this decision was confirmed in appeal by the High Court. In appeal to this Court	 the only contention pressed on behalf of the appellant was '	hat when in a suit to enforce a mortgage instituted after the death of a muslim debtor	 one or more out of the heirs of the deceased is or are not impleaded in the suit and a decree is obtained	 what passes to the auction purchaser at the court sale is only the interest of the heirs who were impleaded; that this was so because each heir is under Mohamedan law liable to satisfy the debts of the deceased only to the extent of 'the share of the debt proportionate to his share in the estate. HELD : (i) The appellant was sufficiently represented in the suit filed in 1940 and was bound by the decree passed in that suit	 (ii) Whether a decree obtained by a creditor against the heirs of a deceased muslim is binding upon the entire estate or only on those who were impleaded eo nomine is not a question to be determined on the personal law either of the deceased or of the defendant in the suit. It is a part of the law of procedure which regulates all matters going to the remedy	 and when the matter passes into the domain of procedure	 it must be regulated by the law governing the action of the court; [944 D] 938 (iii) Where certain persons are impleaded after diligent and bona fide enquiry in the genuine belief '	hat they are the only persons interested in the estate	 the whole estate of the deceased will be duly represented by the persons who are brought on the record or impleaded	 and the decree will be binding on the entire estate. [948 G] Daya Rain and others vs Shyam Sundari & others ; followed. If the creditor has proceeded after such bona fide enquiry	 it would make no difference in principle between a case in which a debtor is sued for recovery of a debt and upon his death pendente lite there is an order of the court recognising the persons brought on the record as representing the estate	 and a case in which in a suit against the heirs of a deceased debtor	 the creditor has taken upon himself the responsibility to bring certain persons on the record as representing the estate. [948 E] This rule will not apply to cases where there has been fraud or collusion between the creditor and the heir impleaded or where there are other circumstances which indicate that there has not been a fair or real trial	 or that the absent heir had a special defence which was not and could not be tried in the earlier proceeding.
