Summarize the following court judgment. Civil Appeal No. 1833 of 1970. Appeal by Special leave from the Judgment and Order dated the 17.4.1970 of the Mysore High Court in Civil Revision Petition No. 1255 of 1969. A.S. Nambiar	 Ashok Kumar Sharma and M. Veerappa for the Appellant. R.B. Datar	 Divender Singh	 Ms. Madhu Moolchandani and Ms. Meenu Verma for the Respondent. The Judgment of the Court was delivered by VARADARAJAN	 J. This appeal by special leave is directed against the Order dated 17.4.1970 of a learned single Judge of the erstwhile Mysore High Court (now Karnataka High Court) in CRP 1255 of 1969 which was filed against an Order dated 3.3.1969 of the Principal Civil Judge	 Bangalore in Misc. Case 6 of 1969	 filed by Kabidi Venku Sah who was the first respondent in the Civil Revision Petition and is the appellant in this Civil Appeal. The Principal Civil Judge allowed the Misc. Case which was filed under Order 21 Rule 58 of the Code of Civil Procedure for raising an attachment over the house property effected at the instance of Syed Abdul Hai who was the petitioner before the High Court in the Civil Revision Petition and is the first respondent in this Civil Appeal. The house property belonged originally to one Vittal Sah who was the husband of the second respondent Sharada Bai. Vittal Sah had executed a 114 simple mortgage over the property in favour of the appellant on 31.7.1948. The appellant obtained a decree on the mortgage on 4.9.1967 in O.S. 217 of 1966 on the file of the Principal Civil Judge and brought the property to sale in execution of that decree and purchased it himself on 24.7.1968 after obtaining the necessary leave of the Court to bid and set off. The sale was confirmed on 28.8.1968 and the appellant took delivery of the property on 28.11.1969 in Misc. Case 95 of 1968 as the court auction purchaser. The first respondent Syed Abdul Hai obtained a money decree against Vittal Sah on 30.3.1967 in O.S. 386 of 1964 on the foot of a promissory note executed in 1961 for a sum of Rs. 20	000. He obtained attachment before judgment over the same house property on 24.9.1964 on the same day on which filed that suit in the Court of the Principal Civil Judge	 Bangalore. He filed E.P. 31 of 1968 for realising the money due under the decree by bringing the house property to sale pursuant to the attachment before judgment effected on 24.9.1964. Thereupon the appellant Venku Sah filed Misc. Case 6 of 1969 under Order 21 Rule 58 of the Code of Civil Procedure for getting the attachment raised	 alleging that the second respondent Sharada Bai had no saleable interest in the property on the date of the attachment and that the first respondent 's simple money decree cannot prevail over his mortgage decree and the sale of the property obtained in his favour in execution of that decree. The first respondent Syed Abdul Hai opposed the claim petition	 contending that the court proceedings referred to in the claim petition are collusive and fraudulent and that the delivery alleged by the appellant is only a paper delivery possession continued to be with the second respondent. The Principal Civil Judge found that the mortgage decree	 execution sale and delivery of the property to the appellant cannot be questioned in the first respondent 's claim petition as being collusive and could be questioned only in a separate suit. He also found that there was no material on record to show that the second respondent continued to be in possession of the property after its delivery to the appellant pursuant to the court auction sale in his favour. He rejected the contention that the appellant was not entitled to file any claim petition under Order 21 Rule 58 of the Code of Civil Procedure for raising the attachment before judgment effected under Order 38 Rule 5 and held that there is nothing on 115 record to show that the appellant was aware of the attachment and therefore there was no delay in filing the claim petition and that the claim petition could be filed under Order 21 Rule 58 even in the case of attachment before judgment in view of the provisions of Order 38 of Rule 8 which says that when any claim is preferred to property which has been attached before judgment	 such claim shall be adjudicated upon in the manner provided for the adjudication of claims to property attached in execution of a decree for payment of money. The Principal Civil Judge rejected the first respondent 's contention that the appellant had no interest in the equity of redemption even if the mortgage in his favour is true and that only the equity of redemption was attached on 24.9.1964 and held that what was attached the entire property and not the equity of redemption alone. In this view	 he allowed the claim petition. Before the High Court it was contended for the first respondent that the appellant should show not only that he had an interest in the property attached on the date of the attachment but also possession thereof on that date before he could get the attachment before he could get the attachment before Judgment raised and that the property belonged to the second respondent 's husband and was in his possession on the date of the attachment and therefore the Principal Civil Judge could not have allowed the claim petition. The appellant refuted that contention by peculiarly contending that he	 a simple mortgagee	 was in constructive possession of the property through the mortgagor. The learned Judge of the High Court rightly rejected the contention that a simple mortgagee could be in possession of the mortgaged property constructively through the mortgagor and held that the appellant (claimant) should show that he had some interest in the property attached on 24.9.1964 and was in actual or constructive possession thereof. He observed that the Principal Civil Judge has not recorded any finding on the question of the appellant 's possession of the property on the date of the attachment and that he has thereby wrongly exercised jurisdiction and acted with material irregularity in allowing the claim petition. He found that the appellant had failed to prove that he had an interest in the property on the date of the attachment and was in possession of the property	 either actual or constructive	 on that date and held that he was therefore not entitled to have the attachment raised. The matter is quite simple but has unfortunately dragged on for nearly 15 years on account of a wrong and ill advised step taken 116 by the appellant. The learned Principal Civil Judge erred in observing that what was attached before judgment on 24.9.1964 is not the equity of redemption alone but the entire property. He has rightly held that in the claim petition the question of the mortgage of 1948	 the mortgage decree	 the court auction sale and delivery of possession of the property to the appellant pursuant to that sale cannot be contended to be collusive and observed that the first respondent could	 if at all	 challenge them only in a separate suit. That being so	 undoubtedly the mortgage of 1948 in favour of the appellant was there and what remained with the mortgagor was only the equity of redemption until it was brought to an end by the sale in execution of the mortgage decree confirmed by the court on 28.8.1968. Therefore	 there could be no doubt whatsoever that on 24.9.1964 when the property was attached before judgment long after the mortgage dated 31.7.1948 and two years before the suit on the mortgage was filed in 1966	 the mortgagor had the equity of redemption and that what could have been attached in law on 24.9.1964 was the equity of redemption alone and not the entire interest in the property. There should have been no difficulty for the learned Judge of the High Court holding that the appellant could not have been in possession of the property	 actual or constructive	 for he was only a simple mortgagee who had nothing to do with possession until he got delivery of the property through the court as a decree holder court auction purchaser on 28.4.1968 as noticed by the learned Judge in his judgment. The appellant had no doubt an interest in the property as mortgagee	 but he could not have been in possession of the property as he was only a simple mortgagee. The appellant was a secured creditor as he had a mortgage in his favour	 and any attachment effected after the date of the mortgage and during its subsistence can be only subject to that mortgage. He had no interest in the equity of redemption on the date of the attachment and could not therefore have had any objection to that right of the mortgagor being attached by the first respondent. Therefore he was not a person who could in law file any claim petition under Order 21 Rule 58 objecting to the attachment of the equity of redemption. We may notice here what Order 21 Rule 58(1) says and it is this: "Where any claim is preferred to	 or any objection is made to the attachment of	 any property attached in execution of a decree on the ground that such property is 117 not liable to such attachment	 the Court shall proceed to adjudicate upon the claim or objection in accordance with the provisions herein contained. " The attaching creditor can bring the property to sale only subject to the mortgage as long as it is subsisting. That is to say he could bring only the mortgagor 's equity of redemption to sale if it had not already been extinguished by its sale in execution of any decree obtained on that mortgage. But if the equity of redemption has already been sold after the date of the attachment the attaching decree holder could proceed only against the balance	 if any	 of the sale price left after satisfying the mortgagee decree holder 's claim under the decree. The mortgagee 's right is thus not affected at all. Therefore it is we had observed carrier that the appellant had taken a wrong and all advised step in coming forward with the claim petition which has resulted in the matter dragging on for over 14 years from 15.1.1969. The appellant could not object to the attachment of the equity of redemption. The appeal fails and is dismissed	 but under the circumstances of the case without costs. H.L.C. Appeal dismissed.

On the basis of a simple mortgage executed in his favour in the year 1948	 the appellant obtained a decree on 4 9 1967	 brought the mortgaged property to sale	 purchased it himself on 24 7 1968 and got the sale confirmed by court on 28 8 1968. The first respondent who held a promissory note executed in his favour by the owner of the said property in 1961	 instituted a suit for recovery of the sum on 24 9 1964 and got the property attached before judgment on the same day and thereafter obtained a money decree on 30 3 1967	 and filed an execution petition for realising the money due under the decree by bringing the property to sale. Thereupon the appellant filed a claim petition under O.21	 r. 58 C.P.C.	 for getting the attachment raised. The claim petition was resisted by the first respondent inter alia on the ground that it was incompetent as the appellant had neither any interest in the equity of redemption nor was he in possession of the property. The trail court allowed the claim petition holding inter alia that what was attached on 24 9 1964 was the entire property and not the equity of redemption alone. The Civil Revision Petition filed by the first respondent against the order of the trial court was allowed by the High Court which held that the appellant having failed to prove that he had an interest in the property on the date of the attachment and was in possession of the property	 either actual or constructive	 on that date he was not entitled to have the attachment raised. Dismissing the appeal	 HELD: The trial court erred in observing that what was attached before judgment on 24 9 1964 was not the equity of redemption but the entire property. There could be no doubt that on 24 9 1964 when the property was attached before judgment long after the mortgage dated 31 7 1948 and two years before the suit was filed on the mortgage in 1966	 the mortgagor had the equity of redemption and that what could have been attached in law on 24 9 1964 was the equity of redemption alone and not the entire interest in the property. The property. The appellant had no doubt an interest in the property as mortgagee	 but he could not have been in possession of the property as he was only a 113 simple mortgagee. He was a secured creditor as he had a mortgage in his favour	 and any attachment effected after the date of the mortgage and during its subsistence could only be subject to that mortgage. Since he had no interest in the equity of redemption on the date of attachment	 he could not have had any objection to that right of the mortgagor being attached by the first respondent. Therefore	 he was not a person who could	 in law	 file any claim petition under O. 21; r. 58 objecting to the attachment of the equity of redemption. [116 A; C D; F H] The attaching creditor can bring the property to sale only subject to the mortgage as long as it is subsisting. That is to say	 he could bring only the mortgagor 's equity of redemption to sale if it had not already been extinguished by it sale in execution of any decree obtained on that mortgage. But if the equity of redemption has already been sold after the date of the attachment	 the attaching decree holder could proceed only against the balance	 if any	 of the sale price left after satisfying the mortgagee decree holder 's claim under the decree. The mortgagee 's right is thus not affected all. [117 B C]
