Summarize the following court judgment. Appeal No. 1203 of 1977. From the Judgment and Order dated 4.12.1973 of the Calcutta High Court in Appeal from Original Order No. 624 of 1968. A.K.Ganguli	 U.R. Lalit	 S.KNandy	 Chandra Nath Mukher jee	 Gaurav Kumar Banerjee	 Ajit Chakravorty	 Narayan Sinha and B.C. Barua for the appellants. G. Ramawamy	 Dr. Shankar Ghosh	 R.F. Nanman	 P.H.Parekh	 Ms. Sunita Sharma	 B.M.Mitra and Dhillon for the Respond ents. The Judgment of the Court was delivered by PUNCHHI	 J. This appeal by certificate	 poses an impor tant question of law	 as to whether	 a court sale held in execution of a final decree	 passed in a suit for recovery of mortgage money	 can be upset under the provisions of section 47 of the Code of Civil Procedure	 on the displace ment of the preliminary decree upon which such final decree was based. The question of law emerges on the facts summarized as follows: 239 Raja Abhoy Narain Deb was the owner of premises No. I 17 A	 Rash Behari Avenue statedly a fashionable quarter of Calcutta	 built on an area approximating 1 Bigha 6 cottahs	 with three storied building on it consisting of 32 spacious rooms and two out houses. On the demise of Raja Abhoy Narain Deb	 the appellant herein	 and the proforma respondents	 succeeded as heirs to the same on September 15	 1949. The appellant and his co heirs mortgaged their two third inter est in the said property as security for a loan of Rs.27	000 obtained from the mortgagor Smt. Prokashini Biswas	 the predecessor in interest of the plaintiffs respondents. After her death some of the heirs and legal representatives of Smt. Biswas	 on March 13	 1961	 filed a mortgage suit for the recovery of the mortgage money etc. in the court of the 3rd Subordinate Judge at Alipore	 being title Suit No.17 of 1961	 seeking enforcement and sale of the mortgaged proper ty. To this suit the left out heir of Smt. Biswas	 original ly arrayed as a defendant	 was transposed as a co plaintiff. On July 25	 1962	 the trial court passed a preliminary decree in the sum of Rs.27000 for the principal sum and a sum of Rs.24570 for interest on the said principal	 totall ing Rs.51570	 together with costs. The sum of Rs.51570 was proportioned in as much as two third was ordered as payable to the original plaintiffs and the remaining one third to the transposed co plaintiff. The decree stipulated that the mortgagors were allowed to pay the decrectal amount in 15 equal annual instalments	 to be deposited by the 30th June of each year	 in the afore mentioned proportions of two third and one third	 to the credit of the respective mortga gee plaintiffs; the first instalment being payable by August 31	 1962. The mortgagee plaintiffs were also allowed interest on the sums due from the date of institution of the suit till the date of realisation of the entire sum. It was further stipulated that in default of any one of the instal ments	 the mortgagee plaintiffs were at liberty to apply for making the decree final	 and in the event of such applica tion being made the mortgaged property	 or a sufficient part thereof	 shall be directed to be sold	 and for such purpose all necessary steps were required to be taken by the plain tiffs mortgagees. On December 18	 1962	 the present proforma respondent no.8	 Kumar Sudhendu Narain Deb	 filed F.A. No. 902 of 1964 against the aforesaid preliminary decree in the Calcutta High Court praying as well for stay of execution of the decree	 which prayer was ultimately declined. Some deposits	 however	 were made to feed the preliminary decree but since there was a failure to deposit in the terms there of	 a final decree was passed by the Court of the 3rd Subor dinate Judge	 Alipore on March 6	 1963	 even though F.A. No. 902 of 1964	 the appeal against the preliminary decree	 was pending in the High Court. The group of the decree holders representing two third interest filed an execution petition for realisation of their own share under the decree 240 which was followed by another execution petition of the remaining decree holder representing one third interest	 seeking realisation of his onethird share of the decreetal amount. Both the execution petitions contained identical prayers for sale of the mortgaged property. The execution petitions were consolidated and numbered as Execution Peti tions 11 and 13 of 1963 respectively. On August 10	 1963	 proclamation of sale was drawn	 apparently in the presence of parties. The decree holders suggested the value of the mortgaged property as Rs.75	000. The appellant herein put its value at Rs.3 lacs. In these circumstances	 the execut ing court ordered that both the valuations be incorporated in the sale proclamation. The sale	 however	 did not take place till March 15	 1968 and a period of over 4 % years passed by in the mean time. By that time	 the value of the property	 according to the appellant	 had risen to Rs.6 lacs for which on March 4	 1968	 before the sale	 the appellant made a regular objection under section 47 of the Code of Civil Procedure. Within the intervening period of 4 1/2 years	 some more deposits apparently were made by the appel lant. The property was all the same sold on March 15	 1968	 on the proclamation of sale as was drawn on August 10	 1963	 for Rs. 1	00	500 in favour of the auction purchasers re spondents 6 & 7 herein. On April 11	 1968	 the appellant yet filed an application under Order 21 Rule 90 C.P.C. for selling aside the sale and prayed for stay of its confirma tion basically on three grounds: (i) the judgment debtors had no saleable interest in the mortgaged property; (ii) legally two execution petitions could not be consoli dated; and (iii) the provisions of section 35 of the Bengal Money Lenders ' Act had been overlooked. This petition was treated as a part of the original objection under section 47 C.P.C. On April 11	 1968	 the objection under section 47 C.P.C. was dismissed by the executing court against which the appellant preferred an appeal before the Calcutta High Court being F.M.A. No.624 of 1968. Later the petition under Order 21 Rule 90 C.P.C. was formally dismissed in default in the above backgrround. On September 14	 1968	 the auction sale was confined. In F.M.A. No.902 of 1964	 the appeal against the prelim inary decree	 the parties arrived at a settlement on Decem ber 13	 1971 before the Calcutta High Court. In place of the preliminary decree dated July 25	 1962 a new preliminary decree on settlement between the parties	 was passed by a division bench of the High Court	 whereunder the decrectal amount was principally agreed not to exceed Rs.54000 being the double 241 of the original debt of Rs.27000. The sums deposited by the appellant	 under interim orders of the court from time to time to the credit of the decree holders	 were adjusted and the final amount struck as unpaid was put at Rs.44000 re garding which claim of the morttgagees was conceded by the appellant mortgager as well as to the manner of its payment	 and which sum in fact was deposited by him in Court	 for not only simultaneous passing of the decree but recording as well it satisfaction. Having cleared off in this manner the mortgage debt	 the appellant in his appeal F.M.A. 624 of 1968	 preferred against the rejection of objection raised the additional legal ground that after the displacement of the original preliminary decree by substitution the final decree did not survive	 and so did succumb the auction sale	 posing amongst others the question set out in the opening paragraph of the judgment. The High Court rejected all the legal pleas otherwise raised but certified as fit questions as raised to be answered by this Court	 without framing any one of them as such. It was pointed out by Mr. Ganguli	 learned counsel for the appellant that the preliminary decree dated July 25	 1962 was a preliminary decree for sale passed in terms of Order 34 Rule 4 of the kind covered under Clause (c) (i) of sub rule (1) of Rule 2 and the final decree dated March 6. 1963 was final decree for sale under Order 34 Rule 5 (3) of the Code of Civil Procedure. This is evident from the copies of both the decrees which are part of the additional documents submitted to this Court. The preliminary decrees for sale	 details apart	 besides striking the amount due payable in instalments	 mentions the time for payment	 further provides that in default of payment as provided	 the plaintiff may apply to the Court for final decree for the sale of the mortgaged property; and on such application being made. The mortgaged property or sufficient part there of. shall be directed to be sold; and for the purpose of such sale	 the plaintiff shall produce before the court or such officer	 as it appoints	 all documents in his posses sion or relating to the mgrtgaged property. It is evident from the terms of the final decree that it was passed on the basis of the preliminary decree dated July 25	 1962 and the plaintiff making an application on September 19	 1962 for a final decree	 and it appearing that the payment directed by the said decree and orders had not been made by the defend ant or any person on his behalf or any other person entitled to redeem the mortgage. the Court then ordered and decreed that the mortgaged property in the preliminary decree afore mentioned	 or a sufficient part thereof	 be sold and that for the purpose of such sale	 the plaintiff shall produce before the Court or such Officer		 as it appoints	 all the documents in his possession or power relating to the mortgaged property. " It is on the strength of terms of both the decrees that Mr. Ganguli urged that the right to apply for the final decree arose from the terms of the 242 preliminary decree and on the failure of the defendant making payments in terms thereof. And since the preliminary decree of July 25	 1962 was displaced and substituted by the preliminary decree passed by the High Court in appeal	 which was instantly satisfied	 the foundation under the final decree stood removed. It was further urged that the plain tiff had lost the right to ask for a final decree	 there was no compulsory need for the purpose or tee occasion to pass it	 It is also urged that the auction has become non est having no legal foundation or sanction in law. The well settled principle of the appeal being a continuation of the suit was pressed into service to contend that the final decree had no life of its own and could only be passed on an application moved by the plaintiff on the defendant 's fail ure to comply with the terms of the substituted preliminary decree. Mr. Nariman	 learned counsel appearing for the respondents on the other hand contended that there could not be a reverse process when the final decree had factually been passed and an auction sale in terms thereof had taken place bringing in the rights of the stranger auctionpurchas ers. In order to appreciate the respective contentions of learned counsel for the parties	 the scheme of Order 34 would be essential to be grasped. It would be seen that Rule 1 thereof enjoins that subject to the provisions of the Code	 all persons having an interest either in the mortgage security or in the fight of redemption shall be joined as parties to any suit relating to the mortgage. Confining to the relevant statutory provisions thereunder	 as are applicable to the case	 the preliminary decree was passed in the foreclosure suit in accordance with sub clause (c)(i) of Clause (1) of Rule 2. Further in terms of sub clause (c)(ii) of Clause (1) of Rule 2	 the Court held the plaintiffs entitled to apply for a final decree	 debarring the defendant from all right to redeem the property. The Court under sub rule (2) of Rule 2 can	 on good cause shown and upon terms to be fixed by the Court from time to time	 at any time before any decree is passed	 extend the time fixed for the payment of the amount found or declared due under sub rule (1) or of the amount adjudged due in respect of subsequent costs	 charges	 expenses and interest. Rule 3 of Order 34 provides that when an application is made by the defendant seeking a final decree	 the Court has two courses open depending on the defendant making payment in Court of all amounts due from him under sub rule (1) of Rule 2	 and not making payment. Under sub rule (1) of Rule 3	 a final decree of one kind may be passed in terms thereof. if pay ment is made. But if no payment is made a final decree of the other kind may be passed in terms of sub rule (2) of Rule 3. Sub rule (3) of Rule 3 enjoins that on the passing of a final decree under sub rule (2) all liabilities to which the defendant is subject in respect of mortgage or on account of suit shall be deemed to have been 243 discharged. Under Rule 5	 the defendant is given another opportunity to make payment of all amounts due from him under sub rule (1) of Rule 4	 if such payment. is made on or before the day fixed or at any time before the confirmation of sale in pursuance of the final decree. It is thus notice able that at every conceivable step opportunity is given to the defendant to redeem the property at any time before the confirmation of sale made in pursuance of the final decree	 and if such deposit is made the Court bas to accept the payment and make an order in favour of the defendam. The Court	 however	 has no power to go on fixing date after date	 in postponing confirmation of sale to accommodate the defendant	 as was held by this Court in Hukumchand vs Bansi lal & Ors; 	 No right is given to the mort gagor defendant to ask for postponement of confirmation of sale in order to enable him to deposit the amount. Reference may also be made to Janak Raj vs Gurdial Singh and Anr	 [1967] 2 SCR wherein it has been laid down that when no application for setting aside a sale has been made to the executing court or when one made under Rules 89 to 91 of Order 21 gets dis missed	 the court has no choice thereafter but to confirm the sale. This Court made significant observation by spell ing out the policy of protecting auction purchasers in the following words: "The policy of the Legislature seems to be that unless a stranger auction purchaser is protected against the vicissitudes 	of the fortunes of the suit	 sales in execution would not attract customers and it would be to the detriment of the interest of the borrower and the creditor alike if sales were allowed to be impugned merely because the decree was ulti mately set aside or modified. The Code of Civil Procedure of 1908 makes ample provision.for the protection of the interest of the judgment debator who feels that the decree ought not to have been passed against hint. _" [Underlining ours] However	 this Court in Sardar Govindrao Mahadik & Ant: vs Devi Sahai & Ors	 ; 	 carved out an excep tion in the case of the auction purchaser who was a decree holder himself	 denying to him the protection given in Janak Raj 's case (supra) to the stranger auction purchaser. As is discernible Sardar Govindrao 'case (supra) and Hukumchand 's case (Supra) are cases distinguishable as against Janak Raj 's case (supra). Whereas Sardar Govindrao 's case (supra) is a case of a mortgagee 'decree holder ' auction purchaser and Hukumchand 's case [supra] relating to a mortgage suit	 Janak Raj 's case (supra) is a case of a simple money decree in execution of which the auction purchaser got to buy the judgment debtors immovable property. Still the underlined words in the extract from Janak Raj 's case (supra) conceiva bly leave to the judgment 244 debtor his rights under the Civil Procedure Code whereby he can have the decree passed against him set aside and to seek appropriate reliefs on the basis thereof. Now coming to the substituted preliminary decree	 even though by consent	 there is no denying the fact that the seal of adjudication gets affixed to it. The Court passing it has formally expressed the terms itself under its own authority	 even though at the suggestion of the parties. It conclusively determines the right of the parties with regard to the matters in controversy valid in the suit till the stage of passing of the preliminary decree. The Explanation to Section 2(2) of the Code of Civil Procedure defining the word "decree"	 goes to say that a decree is preliminary when further proceedings had to be taken before a suit can be completely disposed of. It is final where such adjudication completely disposes of the suit. It may be partly prelimi nary and partly final. The preliminary decree in the instant case	 whether as originally made or as substituted in ap peal	 had not disposed of the suit completely. It was to be enforceable on the terms it was drawn. There were obliga tions for the defendants to fulfil and on the violation to observe these obligations rights accrued to the plaintiffs. If we import this analysis into the understanding of the decree	 the defendants could obviously in appeal against the decree have their obligations altered and the scope and role of re defining the obligations definitely vested in the appellate court. It cannot thus be twistedly said that the obligations of the defendants may substitutedly be that as defined by the appellate preliminary decree	 but the right of the plaintiffs kept accrued on the failure of non fulfil ment of the obligations of the defendants under the prelimi nary decree of the Court of first instance. Is it then conceivable that the appellate preliminary decree was valid for the purposes of defining the obligations of the defend ants	 but was not valid since rights had accrued to the plaintiffs on the non fulfilment of obligations under the preliminary decree of the Court of first instance7 Such an interpretation or construction would render the substantive right of appeal redundant and choked defeating the ends of justice and would otherwise be iII fined in the scheme of Order 34 C.P.C. Therefore. it must be held that in the field the only preliminary decree is the one.which was passed by the Calcutta High Court substituting the original prelimi nary decree of the Trial Court	 and the final decree	 if at all required	 is to be passed in accordance therewith. The fact that the decree was consensualin in nature	 having been passed between the parties to the suit	 is of no consequence. It has the same binding force just as one which could be passed on contest. An objection was raised that to this settlement	 the auction purchasers were 245 not parties and hence not bound by it	 though their interest had appeared on the scene due to the auction purchase. Our attention was invited to Section 47 of the C.P.C. and to Explanation II(a) providing that ' for the purposes of Sec tion 47	 a purchaser of a property in execution of the decree shall be deemed to be a party to the suit in which the decree is passed. It was suggested that the plaintiffs and the defendants could not settle the suit without the consent and participation of the auction purchasers to their detriment. There is an obvious fallacy in the argument. Significantly	 for the purposes of Section 47	 the auction purchaser deemingly is a party to the suit in which the decree is passed if he has purchased the property at the sale and execution of that decree. Instantly	 the auction purchasers had purchased the property in execution of the final decree and not in execution of the preliminary decree and on that basis can at best be deemed to be parties to the suit throughout only on :the strength of the final decree if obtained on the terms of the existing preliminary decree. But here the property	 as said before	 was not put to sale in execution of the preliminary decree. The auction purchas ers cannot claim themselves to be parties to the suit at the time of or at any time prior to the passing of the prelimi nary decree. It is to be remembered that both the prelimi nary decree and final decree are passed under Order 34 of the Code of Civil Procedure in one and the same suit	 in which two decrees may be required to be passed at separate stages. And both being formal adjudications appropriate to the stage are formal expressions of decision of the Court. At the stage of the preliminary decree there arises no question of the property under mortgage being put to sale in execution of the decree	 and if that is so the ultimate auction purchaser cannot be held deemingly to be a party to the suit upto the stage of the preliminary decree. In our opinion	 the converse interpretation that the auction pur chaser at a sale and execution of the final decree shall be deemed to be party to the suit at and prior to the stage when preliminary decree is passed	 unless sustaining	 would be contrary to the spirit and scheme of Order 34 of the Code of Civil Procedure. And since all questions arising between the parties to the suit in which the decree was passed	 or their representatives	 and relating to the execution	 dis charge or satisfaction of the decree are required to be determined by the Court executing the decree and not by a separate suit	 the objection of the appellant judgment debtor with regard to the knocking out of the original preliminary decree was to our mind sustainable. In terms of the preliminary appellate decree and fulfilment of the obligations of the defendants of payment of the sum as struck	 there remained no occasion for entertaining	 main taining or sustaining the application of the plaintiff mortgagees for sale of the property mortgaged and on that basis the auction sale in favour of the auction purchasers and confirmation of that sale automatically becomes non est. We are thus of the considered view that the High Court went wrong in rejecting the objection of the appellant judgment debtor. 246 For the view above taken it would not be necessary to go into the other two questions raised by Mr. Ganguli	 and for which there is warrant in the order of the High Court grant ing certificate	 with regard to violation of section 35 of the Bengal Money Lenders Act	 as well as to settle the effect of the executing court not mentioning its own evalua tion of the property in the proclamation of sale and to have illegally incorporated both the evaluations as suggested by the decree holders and the judgmentdebtors	 rendering the auction sale void. But this is not the end of the matter. The auction purchasers are not on firm footing on the strength of the observations afore quoted in Janak Raj 's case (supra)	 afore distinguished. In that case the relief in the suit was unconnected with the property sold in execution of the decree. Here the relief in the suit is inextricably connect ed with the property sold. The two cannot be divorced di verting them to different courses. The substituted prelimi nary decree is the one passed under Rule 4 of Order 34 and involves the property in dispute. It so happens that the stage of Rule 5 Order 34 stands withdrawn	 rendered non est and wiped out. No compensatory sum is due to the auction purchasers under the strict terms of subrule (2) of Rule 5 of Order 34	 whereunder the defendant mortgagor	 in addition to the payment of all amount due from him under sub rule (1) of Rule 4. is required to deposit a sum equal to 5% of the amount of the purchase	 money paid into the Court by the auction purchaser	 which obviously is meant to compensate the auction purchaser. That stage in the eye of law has not arrived. Since in strict sense the provisions would not be applicable to the facts of the instant case	 we in exercise of the Court 's inherent powers under the Code and powers otherwise under Article 142 of the Constitution	 to further the cause of complete justice	 confining it to the facts of this case	 and to be fair to the auction purchasers	 direct the appellant to burden himself in paying to the auction purchasers	 interest on their blocked sum of Rs. 1	05	000	 the purchase money	 lying in Court since 1963	 which we quantify as equivalent to the sum deposited. We thus allow this appeal on the condition that the appellant shall depos it in the executing Court a sum of Rs.1	05	000	 within a period of two months from this date and direct that this sum together with the sum of Rs. 1	05	000	 lying in deposit as auction money be paid over by the executing Court to the auction purchasers	 singularly or collectively	 at the convenience of the auction purchasers. In the facts and circumstances of the case	 however	 we leave the parties to bear their own costs in this Court. V.P.R. Appeal allowed.

The appellant and his co heirs mortgaged their two third interest in the property as security for a loan of Rs. 27	000 obtained from one Smt. Biswas	 the predecessor in interest of the plaintiffsrespondents. After the death of the mortgagee	 some of her heirs and legal representatives filed a mortgage suit on 13.3.1961 for the recovery of the mortgage money before the Subordinate Judge and seeking enforcement and sale of the mortgaged property. The left out heir of the mortgagee	 originally arrayed as a defendant was transposed. as a co plaintiff. On 25.7.1962	 the trial court passed a preliminary decree for. Rs.51	570 totalling the principal sum and inter est	 and costs. The 234 decretal amount was proportioned in as much as two third was ordered as payable to the original plaintiffs and the re maining onethird to the transposed co plaintiff. The decre tal amount was to be paid by the mortgagors in 15 equal annual instalments and in default of any one of the instal ments	 the mortgagee plaintiffs were at liberty to apply for making the decree final and in the event of such application being made the mortgaged property	 or a part thereof	 shall be directed to be sold. Interest also was allowed on the sum due from the date of institution of the suit till the date of realisation of the entire sum. On 18.12.1962	 the proforma respondent no.8 filed an appeal against the preliminary decree in the High Court. Prayer for stay of execution of the decree was rejected. Though some deposits were made on the basis of the preliminary decree	 there was a failure to deposit in terms thereof. Therefore a final decree was passed by the trial court on 6.3.1963	 when the appeal against the preliminary decree was pending in the High Court. The decree holders representing two third interest and the decree holder representing one third interest filed two separate execution petitions for realisation of their shares under the decree. Both the execution petitions contained identical prayers for sale of the mortgaged property and the execution petitions were consolidated and numbered. On 10.8.1963	 proclamation of sale was drawn. The value of the mortgaged property was suggested as Rs. 75	000 and Rs. 3 lacs	 by the decree holders and the appellant respectively. On 4.3.1968	 before the sale of the property	 the appellant made a regular objection u/s 47	 C.P.C. The appel lant had also made some more deposits within the intervening period of 41/2 years. The property was sold on 15.3.1968 on the proclamation of sale as was drawn on 10.8.1963 for Rs. 1	00	500 in favour of the auction purchasers [respondents nos. 6 & 7]. On 11.4.1968 the appellant filed an application under Order 21	 Rule 90	 C.P.C. for setting aside the sale and prayed for stay of its confirmation on the grounds that the judgment debtors had no 235 saleable interest in the mortgaged property; that legally two execution petitions could not be consolidated; and that the provisions of section 35 of the Bengal Money Lenders ' Act had been overlooked. The application under Order 21 Rule 90 was treated as part of the original objection section 47	 C.P.C. The executing Court on 11.4.1968 dismissed the objection u/s 47 C.P.C. against which the appellant preferred an appeal before the High Court. Later the petition under Order 21 Rule 90	 C.P.C. was formally dismissed in default. On 14.9.1968 the auction sale was confirmed. In the appeal against the preliminary decree	 the par ties arrived at a settlement on 13.12.1971 before the High Court. In the place of the preliminary decree dated 21.7.1962 a new preliminary decree on settlement between the parties was passed by the High Court	 whereunder the secre tal amount was principally agreed not to exceed Rs.54	000. The sums deposited by the appellant were adjusted and the final amount struck as unpaid was put at Rs.44	000. Having cleared off the mortgage debt	 the appellant in his appeal	 preferred against the rejection of objection	 raised the additional legal ground that after the displace ment of the original preliminary decree by substitution	 the final decree as well as the auction sale did not survive. The High Court rejected all the legal points otherwise raised	 but certified as fit questions as raised to be answered by this Court without framing anyone of them as such. Hence this appeal by certificate	 involving the question of law as to whether a court sale held in execution of a final decree	 passed in a suit for recovery of mortgage money can be upset under the provisions of section 47 of C.P.C.	 on the displacement of the preliminary decree upon which such final decree was based. The appellant contended that the preliminary decree dated 25.7.1962 was a preliminary decree for sale passed in terms of Order 34 Rule 4 and the final decree dated 6.3.1963 was a final decree for sale under Order 34 Rule 5(3) of the C.P.C.	 that the 236 right to apply for the final decree arose from the terms of the preliminary decree and on the failure of the defendant making payments in terms thereof. And since the preliminary decree of 25.7.1962 was displaced and substituted by the preliminary decree passed b) the High Court in appeal	 which was instantly satisfied	 the foundation under the final decree stood removed; that the plaintiff had lost the right to ask for a final decree	 there was no compulsion for the purpose or the occasion to pass it; and that the auction had become non est having no legal foundation or sanction in law. The respondents on the other hand contended that there could not be a reverse process when the final decree had factually been passed and an auction sale in terms thereof had taken place bringing in the rights of the stranger auction purchasers. Allowing the appeal of the judgment debtor appellant	 this Court	 HELD: 1. On the substitution of the preliminary decree	 even though by consent	 there is no denying the fact that the seal of adjudication gets affixed to it. The court passing it has formally expressed the terms itself under its own authority	 even though at the suggestion of the parties. It conclusively determines the right of the parties with regard to the matters in controversy valid in the suit till the stage of passing of the preliminary decree. In the field	 the only preliminary decree is the one	 which was passed by the High Court substituting the original prelimi nary decree of the Trial Court	 and the final decree	 if at all required	 is to be passed in accordance therewith. [244 B	 G] 2. The Explanation to Section 2(2) of the Code of Civil Procedure defining the word "decree"	 goes to say that a decree is preliminary when further proceedings had to be taken before a suit can be completely disposed of. It is final where such adjudication completely disposes of the suit. It may be partly preliminary and partly final. [244 C] 3. In the instant case the preliminary decree whether as originally made or as substituted in appeal	 had not disposed of the suit completely. It was to be enforceable on the terms it was drawn. There were obligations for the defendants to fulfil and on the violation to observe the obligations	 rights accrued to the plaintiffs. It cannot be twistedly said that the obligations of the defendants may substitutedly be that as defined by the appellate prelimi nary decree	 but the right of the plaintiffs kept accrued on the failure of non fulfilment of the 237 obligations of the defendants under the preliminary decree of the Court of first instance. Such an interpretation or construction would render the substantive right of appeal redundant and choked defeating the ends of justice and would otherwise be ill fitted in the scheme of Order 34	 C.P.C. [244 D F] 4. For the purposes of Section 47	 the auction purchas er deemingly is a party to the suit in which the decree is passed if he has purchased the property at the sale and execution of that decree. [245 B] 5. Instantly	 the auction purchasers had purchased the property in execution Of the final decree and not in execu tion of the preliminary decree and on that basis can at best be deemed to be parties to the suit throughout only on the strength the final decree if obtained on the terms of the existing preliminary decree. But the property was not put to sale in execution of the preliminary decree. The auction purchasers cannot claim themselves to be parties to the suit at the time of or at any time prior to the passing of the preliminary decree. The preliminary decree and final decree are passed under Order 34 of the Code of Civil Procedure in one and the same suit	 in which two decrees may be required to be passed at separate stages. And both being formal adjudications to the stage are formal expressions of deci sion of the Court. At the stage of the preliminary decree there arises no question of the property under mortgage being put to sale in execution of the decree	 and if that is so the ultimate auction purchaser cannot be held deemingly to be party to the suit upto the stage of the preliminary decree. [245 B E] 6. The converse interpretation that the auction pur chaser at a sale and execution of the final decree shall be deemed to be a party to the suit at and prior to the stage when preliminary decree is passed	 unless sustaining	 would be contrary to the spirit and scheme of Order 34 of the Code of Civil Procedure. And since all questions arising between the parties to the suit in which the decree was passed	 or their representatives	 and relating to the execution dis charge or satisfaction of the decree are required to be determined by the Court executing the decree and not by a separate suit	 the objection of the appellant judgment debtor with regard to the knocking out of the original preliminary decree was sustainable. [245 E G] 7. In terms of the preliminary appellate decree and fulfilment of the obligations of the defendants on payment of the sum as struck	 there remained no occasion for enter taining	 maintaining or 238 sustaining the application of the plaintiff mortgagees for sale of the property mortgaged and on that basis the auction sale in favour of the auction purchasers and confirmation of that sale automatically becomes non est.
