Summarize the following court judgment. Appeal No. 398 of 1962. Appeal by special leave from the judgment and decree dated January 7	 1959	 of the Orissa High Court in Appeal from Original Decree No. 57 of 1953. B.R. L. Iyengar	 section K. Mehta and K. L. Mehta	 for the appellant. K. Blimsankaram	 B. Parthasarthy	 J. B. Dadachanji	 O. C. Mathur and Ravinder Narain	 for the respondent. April 24	 1964. The judgment of the Court was delivered by J. RAGHUBAR DAYAL	 J. This appeal	 by special leave	 raises the question of the correct interpretation of section 18(a) of the (Act I of 1877)	 hereinafter called the Act. 859 Ramchandra	 respondent	 executed an agreement to sell the house in suit to the appellant	 on February 21	 1951. The agreement stated that he was in sole possession and en joyment of the house which was his paternal property	 that he was the Managing Member and Karta of the family and that for meeting family necessities and discharging certain loans he agreed to sell his undisputed house for Rs. 6	000/on condition that he and his mother would execute a deed of sale in favour of the appellant with respect to the house within a period of one year from the date of the execution of the deed of agreement. Ramchandra did not execute the sale deed and the appellant instituted the suit for specific performance of the contract. The trial Court held that the sale was not to be for legal necessity and therefore decreed the suit in part	 on the appellant 's depositing a sum of Rs. 6	000/ less the sum of Rs. 300/ paid before the Sub Registrar at the time of the execution of the agreement to sell and less the amount of costs granted to the appellant against Ramchandra within a month and directed that defendant No. 1 would execute the sale deed for the alienation of his interest in the entire house as covered by the agreement and that the plaintiff would be entitled to get possession of the same jointly with defendant No. 2	 mother of Ramchandra. The appellant went up in appeal to the High Court against the dismissal of his suit with respect to the sale of half the house. During the pendency of the appeal Ramchandra 's mother died and therefore the only question urged on behalf of the appellant at the hearing of the appeal was that Ramchandra	 respondent	 having perfected his title to the entire house	 be made to sell the same. The High Court did not agree with the contention and held that section 18(a) of the Act did not apply to the facts of the case as it comes into operation subsequent to the sale having taken place. The High Court therefore dismissed the appeal. It is against this order that this apeal has been filed. Section 18(a) of the Act reads: "Where a person contracts to sell or let certain property	 having only an imperfect title thereto	 the purchaser or lessee (except as otherwise provided by this Chapter) has the following rights: (a)if the vendor or lessor has subsequently to the sale or lease acquired any interest in the property	 the purchaser or lessee may compel him to make good the contract out of such interest;" 860 The question is whether the expression 'subsequently to the sale or lease ' means 'subsequently to the contract to sell or let ' or means 'subsequently to the execution of the sale deed or lease deed by the vendor or the lessor	 as the case may be ' in pursuance of the contract to sell or let. It is contended for the appellant that this expression means subsequently to the contract to sell or let	 while the contention for the respondent is that it means subsequent to the actual sale or lease. We are inclined to agree with the contention for the appellant. The case	 in a way	 is concluded by the decision of this Court in Kalyanpur Lime Works Ltd. vs State of Bihar(1). In that case the Government agreed to let the lease of the bills to Kalyanpur Lime Works Ltd.	 but the lease could not be executed as the forfeiture of the lease of a previous lessee was held invalid by the Court. When the lease of the previous lessee expired	 Kalyanpur Works Ltd.	 wanted the execution of the lease for a period during which the lease to it would have continued if it had been granted in 1934. This Court held that the case fell within section 18(a) of the Act. It said at p. 972: "We agree with the High Court that section 18(a) of the applies to the case. That section lays down that where a person contracts to sell or let certain property having only imperfect title thereto	 if the vendor or lessor has subsequently to the sale or lease acquired any interest in the property	 the purchaser or lessee may compel him to make good the contract out of such interest. There can be no doubt whatever that when the Government entered into the contract to grant leases to the Lime Co. in 1934	 it had an imperfect title	 inasmuch as it could not grant a fresh lease to anyone during the existence of the previous lease in favour of Kuchwar Co. No doubt the Government thought it had the right to forfeit those leases and did in fact order forfeiture but it having been found subsequently that the forfeiture was legally invalid	 rights of the previous lessees were restored. As already pointed out above this is not the case of absence of title but is one of imperfect title and hence falls within the meaning of section 18. After the 31st March	 1948	 when the leases in favour of Kuchwar Co. expired	 the impediment in the way of the Government to grant leases of the property stood removed	 and the Lime Company 's right to get the leases revived in its favour. This right ; 861 of the plaintiff was resisted by the Government who	 on the other hand	 granted the leases to defendant No. 2. The High Court of Patna rightly took the view that section 18(a) was applicable to the facts of this case and although defendant No. 1 was not in a position to grant a lease from the time it agreed to do	 the impediment being now removed and a suit for specific performance not being barred	 the Lime Company was entitled to sue for that relief. We have already held in agreement with the view of the High Court that section 18 is attracted to the facts of this case	 and the contract of which specific performance can be decreed in favour of the plaintiff is the one embodied in Exhibits 22 and 22(a). " It is urged for the respondent that in that case it was not contended before this Court that s.18(a) could not apply to the facts of the case as no lease in favour of Kalyanpur Lime Works Ltd. had been executed and that therefore the question now before us was not discussed. It is also urged that the Patna High Court had not actually applied the pro visions of section 18(a) to the facts of the case but had decreed the specific performance of the contract on the basis of the general principle that the purchaser in a contract to sell entered into in the circumstances of the case	 was entitled to sue for specific performance against such interest as the vendor might afterwards acquire in the property and support was found in what was said in article 994 in Fry 's 'Specific Performance '	 5th Edition. In these circumstances	 we would like to consider the question directly before us. Sections 12 to 20 of Chapter 11 of the Act deal with con tracts which may be specifically enforced. Section 18(a) deals with the rights of the purchaser or lessee in cases where the vendor has imperfect title to the property which he has contracted to sell or let. Apparently this must deal with the rights of the would be purchaser or lessee	 and not of those who have already got the sale or lease of the property in pursuance of the contract to sell or let. If the person who contracted to sell or let has completed the sale or the lease transaction	 nothing is left for the vendee or the lessee to seek by way of specific performance of the contract. This is when he himself acts according to the contract. If he does not act according to the contract	 the person who has agreed to purchase or take on lease the property will have to seek enforcement of the contract through Court and then it may be that the Court might not enforce the contract. The Court will not	 in view of the provisions of sections 14 to 17 be able to 862 enforce the contract even with respect to the property over which the person contracting to sell or let had perfect title	. except in certain special circumstances	 dealt with in sections 14	. 15 and 16. Section 14 deals with cases where the part of the contract which could not be performed bears only a small proportion to the whole in value and admits of compensation in money. Section 16 deals with the specific performance of a part of a contract when that stands on a separate and independent footing from another part of the same contract which cannot or ought not to be specifically performed. Cases. coming under these two sections are not expected to give rise to circumstances in which provisions of sub cl. (a) of section 18 can be applied. Section 15 deals with the specific perform ance of a contract where the part unperformed is large. The Court has discretion in such circumstances to direct the party in default to perform specifically so much part of the contract as it could perform provided that the plaintiff re linquishes all claims to further performance	 and all right to compensation either for the deficiency	 or for the loss ordamage sustained by him through the default of the defen dant. When a Court has dealt with a case under section 15	 no question can however arise for action under section 18(a). It follows	 from the consideration of both the sets of circum stances	 viz.	 when the person contracting to sell or let him self performs his part of the contract and when he is made to perform the contract wholly or partially by Court	 the occasion to apply for specific performance of the contract with respect to the property over which the person contracting to sell or let had originally imperfect title	 does not arise. This points to the conclusion that this clause cannot therefore be restricted in its application to cases where actual sale or lease of property had taken place. If clause (a) of section 18 was to apply after the completion of the sale or lease and on the vendor or lessor acquiring interest in the property in which he had imperfect title to start with	 there would be considerable overlapping between the provisions of cl. (a) of section 18 and section 43 of the Transfer of Property Act. Section 43 of the Transfer of Property Act comes into play when a person fraudulently or erroneously represents that he is authorised to transfer certain immoveable property and professes to transfer such property for consideration	 while cl. (a) of section 18 would come into play when the person with imperfect title has sold or leased the property. There is some sort of representation whenever a person sells or leases property	 the representation being implicit and to the 863 effect that he is competent to sell or let the property. Thus there is over lapping of the provisions of the two sections. The actual right of the transferee under section 43 and cl. (a) of section 18 is however expressed in different language. In cases where section 43 operates	 the transferee	 at his option	 can have the transfer operate on any interest which the transferor may acquire in the property at any time during which the contract for transfer subsists. The illustration to the section indicates that the transferee can require the transferor to deliver the property acquired to him. The purchaser or lessee on the other hand	 acting under cl. (a) of section 18	 can compel the seller or the lessor to make good the contract out of such interest. The difference between the two provisions is this that in the case of the operation of section 43	 no recourse to Court is necessary. The transfer operates on the property transferred and the transferee can call upon the transferor to deliver the property to him. The purchaser or the lessor having the right mentioned in cl. (a) of section 18 has to go to Court to compel the vendor or lessor to perform the contract out of the interest subsequently acquired by him. The purchaser or lessee goes to the Court to enforce the contract and the contract in cl. (a) of section 18 must refer to the contract to sell or let and not to the contract of sale or lease	 which	 as indicated earlier	 if voluntary	 would have covered the entire property contracted to be sold or leased	 and if enforced through Court no occasion for the operation of clause (a) of section 18 would arise. The expression in cl. (a) of section 18 should preferably be construed in a way so that there will be no overlapping bet ween the provisions of this clause and of section 43 of the Transfer of Property Act	 as ordinarily the legislature does not intend to make duplicate provisions for similar situations. The use of the words 'vendor or lessor ' in cl. (a) are no definite pointers to the conclusion that the expression 	subsequently to the sale or lease ' be given the meaning subsequently to the actual sale or lease '. The sections preceding section 18 deal with specific performance of contracts in general and therefore use the expression 'party to a contract '. Section 18 deals with the cases of contracts to sell or let and therefore appropriately uses the simple word 'vendor ' or 'lessor ' with respect to the party contracting to sell or let and 'purchaser ' or 'lessee ' with respect to the party agreeing to purchase or take the property on lease. There is no incongruity in using such expressions so long as one knows to whom those expressions refer. In fact the word 'purchaser ' or 'lessee ' can be appropriately applied to persons agreeing to purchase or take the property on lease. 864 In this connection reference may also be made to the provisions of cl. (d) of section 18 which uses the words 'vendor or lessor ' and provides that where the vendor or lessor sues			for specific performance of the contract and the suit is dismissed on the ground of his imperfect title	 the defendant has a right to a return of his deposit. and to a lien for such deposit. . on the interest of the vendor or lessor in the property agreed to be sold or let. It is clear that the words vendor or lessor in this clause refer to the person contracting to sell or let the property and who did not perform his part of the contract. Section 25 of the Act also uses the expression 'vendor or lessor ' who has not actually sold or leased the property. It provides inter alia that a contract for the sale or letting of property cannot be specifically enforced in favour of the vendor or lessor who comes within the provisions of cls. (a) to (c) of the section. The provisions of section 27A also use the expression 'lessor and lessee ' in connection with provisions relating to the contract to let when actually no lease is executed. There may be another reason for using the expression `sale or lease ' in cl. (a) of section 18. Section 13 and illustration (a) read: "13. Notwithstanding anything contained in section 56 of the Indian Contract Act	 a contract is not wholly impossible of performance because a portion of its subject matter	 existing at its date	 has ceased to exist at the time of the performance. Illustrations (a)A	 contracts to sell a house to B	 for a lakh of rupees. The day after the contract is made	 the house is destroyed by a cyclone. B	 may be compelled to perform his part of the contract by paying the purchase money. * * * * In Pollock & Mulla 's ' '	 8th edition	 under section 13	 is a note: "Illustration (a) assumes that a contract for the sale of a house does	 of itself	 transfer the beneficial interest in the house to the purchaser	 and make him owner in equity in the English phrase. This was also the law here before the 	 came into force. By section 54 of that Act it is provided that a contract for the sale of immoveable property does not	 of itself. 865 create any interest in or charge on such property. By section 55(5) it is enacted that the risk of destruction is borne by the purchaser only from the date when the ownership appears to pass on execution of a proper conveyance by the vendor [see section 55(l)(d)]. It would	 therefore	 seem that the illustration cannot now be applied where the is in force. " It may be that just as illustration (a) to section 13 continues in the Act	 the expression 'sale or lease ' continued in cl. (a) 	of section 18 as at the time cl. (a) of section 18 was originally enacted some sort of beneficial interest had passed to the person agreeing to purchase the property by the mere agreement to sell	 arrived at between the parties. It has also been urged for the respondent that cl. (a) of section 18 of the Act applies only when the person contracting to sell or let has imperfect title to the property and not when be is not entitled to the property as is the case in this suit	 	as Ramchandra had no title to half the house. We do not consider it necessary to decide this question as we are 	of opinion that it cannot be said that Ramchandra had no interest in half the house. He had interest in the entire house and so had his mother	 though in case of actual partition the interest of each would have been fixed at half. If Ramchandra was not competent to pass title with respect to the entire house during the life time of his mother	 he can be said to have imperfect title to it. We are therefore of opinion that on the death of the mother	 Ramchandra obtained title to and interest in the portion of the house which on a private partition subsequent to the contract to sell had taken place between Ramchandra and his mother and that therefore he has to make good his contract out of the property he acquired subsequent to the contract to sell. It has been submitted for the respondent that it need not be taken for granted that Ramchandra got title to the property which belonged to his mother as it might be that the mother had executed some will. No such allegation appears to have been made before the High Court where it was urged that Ramchandra had acquired title to that portion of the house. It was in view of this allegation that the appellant did not argue the appeal on the basis of the ground that had been taken in the memorandum of appeal	 the ground being that Ramchandra had agreed to sell for reasons 	of legal necessity. We therefore do not consider any force in this contention. L/P(D)) 1 S.C.I 28. 866 We hold that the High Court was wrong in not applying the provisions of cl. (a) of section 18 of the Act to the facts of the case. We therefore allow the appeal	 set aside the orders of the Courts below and decree the plaintiff 's suit and order that on payment of Rs. 6	000/ minus Rs. 300/ paid to the respondent at the time of the execution of the agreement for sale and such other costs to which the appellant be entitled within a month from the date of the costs being taxed	 the respondent will be directed to execute the sale deed of the entire house covered by the agreement in favour of the appellant. The appellant will get his costs of the trial Court	 as decreed by that Court	 and of the appeal in this Court	 the parties bearing their own costs of the appeal in the High Court. In case the appellant fails to deposit the amount aforesaid within the time allowed	 his suit will stand dismissed with costs throughout. Appeal allowed.

The respondent executed an agreement to sell his house in order to meet family necessities for a certain sum on the condition that he and his mother would execute a sale deed in favour of the appellant	 On the failure of the execution of the sale deed the appellant instituted a suit for specific performance of the contract. The trial court held that the sale was not for legal necessity and therefore decreed the suit in part directing that the respondent would execute the sale deed for the alienation of his interest in the entire house and that the appellant would be entitled to get possession of the same jointly with the respondent 's mother. The appellant appealed to the High Court and during its pendency the respondent 's mother died and therefore the only question urged on behalf of the appellant was that the respondent	 having perfected his title to the entire house	 be made to sell the same. The High Court did not agree with the contention and held that section 18 (a) of the Specific Relief Act did not apply to the facts of the case as it comes into operation subsequent to the sale having taken place. On appeal by special leave. Held: The High Court was wrong in not applying the provisions of section 18(a) of the Act to the facts of the case. The expression 'subsequently to the sale or lease ' in section 18(a) means subsequently to the contract to sell or let. This clause cannot be restricted in its application to cases where actual sale or lease of property had taken place. Kalyanpur Lime Works Ltd. vs State of Bihar	 [1954] S.C.R. 958	 referred to.
