Summarize the following court judgment. ivil Appeal No. 1308 of 1990. From the Judgment and Order dated 9.12.86 of the Madras High Court in A.A.O. No. 421/83. K. Parasaran	 B. Ramamoorthy and V. Balachandran for the Appellant. M.R. Narayanaswamy and A.T.M. Sampath for the Respond ents. The Judgment of the Court was delivered by THOMMEN	 J. Special leave is granted. This appeal arises from the judgment of the Madras High Court in A.A.O. No. 421 of 1983. The sole question that arises for consideration is as regards the period of limita tion for making a deposit to make an application under Rule 89 of Order XXI of the Civil Procedure Code	 1908 to set aside sale of immovable property sold in execution of a decree. Has the deposit to be made within 30 days from the date of sale as required by sub rule (2) of Rule 92 of Order XXI or within 60 days from the date of sale as provided in Article 127 of the ? The High Court by the impugned judgment held that Arti cle 127 governed the period of limitation to make a deposit in terms of Rule 89. In coming to that conclusion the High Court followed its earlier decision in Thangammal & Ors. vs K. Dhanalakshmi & Anr.	 AIR 1981 Mad. 254 and the decision of this Court in Basavantappa vs Gangadhar Narayan Dharwad kar & Anr.; 	 In the latter decision	 a Bench of two Judges of this Court held that Thangammal (supra) was correctly decided on the point and the deposit made within 60 days from the date of sale was well within time. 485 We shall read the relevant provisions insofar as they are material. Rule 89 of Order XXI provides: "89. Application to set aside sale on deposit. (1) Where immovable property has been sold in execution of a decree	 any person claiming an interest in the property sold at the time of the sale or at the time of making the application	 or acting for or in the interest of such person	 may apply to have the sale set aside on his depositing in Court	 (a) for payment to the purchaser	 a sum equal to five per cent of the purchase money	 and (b) for payment to the decree holder	 the amount specified in the proclamation of sale as that for the recovery of which the sale was ordered	 less any amount which may	 since the date of such proclamation of sale	 have been received by the decree holder	 Rule 92(2) of Order XXI reads: (2) . . . . where	 in the case of an applica tion under Rule 89	 the deposit required by that rule is made within thirty days from the date of sale	 [or in cases where the amount deposited under Rule 89 is found to be deficient owing to any clerical or arithmetical mistake on the part of the depositor and such deficiency has been made good within such time as may be fixed by the Court	 the Court shall make an order setting aside the sale]. The words shown in bracket in Rule 92(2) were substitut ed by section 72 of the Civil Procedure Code (Amendment) Act	 1976 with effect from 1.2.1977. The object of the amendment was to afford an opportunity to the applicant to make good any deficiency in the amount deposited under Rule 89 when the deficiency occurred by reason of clerical or arithmetical mistake on his part. That amendment has no relevance to the point in issue as regards the period of limitation except to emphasise that sub rule (2) of Rule 92 had received the special attention of Parliament in 1976. Parliament addressed itself particularly to the sub rule	 and yet did not	 apart from the special 486 contingency provided for by the amendment	 think it neces sary to extend the period generally prescribed under Rule 92(2) to make the deposit which is a condition precedent to an application to set aside a sale. Rule 89 postulates an application on deposit. It says "may apply to have the sale set aside on his depositing in Court". These words show that deposit is a condition prece dent to the making of an application to set aside a sale. That condition must be satisfied within the period pre scribed by sub rule (2) of Rule 92	 which undoubtedly is 30 days. Parliament refused to alter that provision even when a part of the sub rule was substituted. No doubt on this aspect would probably have arisen had it not been for the longer period prescribed by Article 127 of the (as substituted by the Amending Act 104 of 1976 with effect from 1.2.1977) for making an application under Rule 89. That Article reads: Description Period of Time from which of suit limitation period begins to run 127. To set aside Sixty The date of a sale in execution days the sale of a decree includ ing any such applica tion by a judgment debtor. " Prior to the Amending Act 104 of 1976 the period pre scribed by Article 127 was 30 days. As a result of the amendment	 a period of 60 days is provided for making an application to set aside a sale. It is important to remember that Article 127 appears in Part I of Third Division of the Schedule to the 	 dealing exclusively with applications. Article 127 thus relates solely to the making of an application and not to a deposit. This Article governs applications made under Rules 90 and 91 as well	 but we are not concerned with them. It is true that prior to the Amending Act 104 of 1976	 the period prescribed for the making of an application was identical to that for the 487 making of a deposit. But as a result of the amendment	 different periods are now prescribed for the making of the deposit and the application. That it was the legislative intent to provide different periods of limitation for these two matters is	 from the language used in the two enact ments	 clear and explicit. The reason why the legislature provided for different periods for the two matters which are the necessary steps one following the other to be taken for setting aside the sale of an immovable property sold in execution of a decree is not for the Court to question. This Court would not assume that the legislature made a mistake in this respect or made an omission in accomplishing what it had set out to achieve. There is no inconsistency between the two sets of provi sions prescribing different periods of limitation. Such inconsistency can arise only if obedience of one provision will result in disobedience of the other. While Rule 92(2) requires a deposit to be made within 30 days from the date of sale	 Article 127 requires an application contemplated under Rule 89 to be made within 60 days from the date of sale. As stated earlier	 the deposit must necessarily pre cede the application for no application under Rule 89 can be made except on depositing the amount in Court. We see no inconsistency in these two sets of provisions. The words of the statutes being clear	 explicit and unambiguous	 there is no scope to have recourse to external aid for their construction. Nevertheless in deference to the arguments of the respondents ' counsel	 we would refer to the Statement of Objects and Reasons in respect of clause 102 of the Bill introduced in the Lok Sabha on 8th April	 1974 [Published in the Gazette of India (Extraordinary) Part II	 Section 2	 dated April 8	 1974] amending Article 127. It states: "Clause 102 (Amendment of the Schedule to the Limitation Act	 1953) An application to set aside a sale in execution of a decree on deposit under Rule 89 of Order XXI is re quired to be made within thirty days from the date of the sale. Experience shows that this period is too short and often causes hardship because the judgment debtors usually fail to arrange for moneys within that time. Banks usually take more than thirty days to sanction loans and advances. In the circumstances	 entry 127 of the Schedule to the is being amended to increase the period of limitation to sixty days in respect of an application to set aside a sale in execution of a decree. This increase in 488 the period of limitation will not affect the purchaser because five per cent of the purchase money is required to be paid to him. The advantage of the increased period of limitation will also be available to an application under Rule 90 or Rule 91 of Order XXI to set aside a sale in execution of a decree. In view of the increase in the period of limitation	 confirmation of a sale will have to await the expiry of the increased period of limitation." (emphasis supplied) The legislative intent	 as seen from the above state ment	 was indeed to extend the period prescribed for making an application and not for any other purpose. That is the reason why Article 127 was amended enlarging the period for making an application from 30 days to 60 days. That period has no bearing on the time allowed for making a deposit in respect of which the period is prescribed	 not under Article 127	 but under Rule 92(2) of Order XXI	 and this period has always been	 and remains to be	 30 days. We see no repug nance or inconsistency or lack of clarity in these two sets of provisions. Appearing for the appellant (the auction purchaser)	 Mr. Parasaran submits that the High Court was not justified in attempting to correct or supply	 what it thought to be	 a defect or an omission in the statute. He rightly contends that even if there was an omission	 it was not for the Court to rectify it. The Court must indeed proceed on the assumption that the legislature did not make a mistake and that it intended to say what it said: See Nalinakhya Bysack vs Shyam Sunder Haldar & Ors.	 ; at 545. Assuming there is a defect or an omission in the words used by the legislature	 the Court would not go to its aid to correct or make up the deficiency. The Court cannot add words to a statute or read words into it which are not there	 especially when the literal reading produces an intelligible result. "No case can be found to authorise any court to alter a word so as to produce a casus omissus": Per Lord Halsbury	 Mersey Docks vs Henderson. 	 602. "We cannot aid the legislature 's defective phrasing of an Act	 we cannot add and mend	 and	 by construction	 make up deficiencies which are left there": Crawford vs Spooner	 ; 	 8	 9. Where the language of the statute leads to manifest contra diction 489 Of the apparent purpose of the enactment	 the Court can	 of course	 adopt a construction which will carry out the obvi ous intention of the legislature. In doing so "a judge must not alter the material of which the Act is woven	 but he can and should iron out the creases.": Per Denning	 L.J.	 as he then was	 Seaford Court Estates vs Asher	 All E.R. [1949] 2 155 at 164. See the observation of Sarkar	 J. in M. Pentiah & Ors. vs Muddala Veeramallapa & Ors.	 ; at 314. In the construction of the relevant provisions	 we see no contradiction or ambiguity or defect or omission. We see no merit in the argument that Article 127 must override Rule 92(2) of Order XXI in respect of limitation. We view both the provisions as prescriptive of time for different pur poses	 and of equal efficacy and particularity. The maxim generalia specialibus non derogant has no relevance to their construction. Nor does the principal in Heydon 's case ; 76 ER 637 offer any help on the point in issue. The mischief which the legislature had set out to remedy by amendment of Article is what is stated in the objects and reasons clause. That object was accomplished by prescribing a longer period for filing an application to set aside a sale in execution of a decree. Further more	 as already seen	 by amendment of Rule 92(2) of Order XXI an opportunity was accorded to the depositor to make good the deficiency in the deposit made by him due to arithmetical or clerical mistake on his part. In no other respect did the legislature evince an intention to extend the period prescribed for making the deposit. It would perhaps have been better	 more logical	 reasonable and practical	 as stated by the Kerala High Court in Dakshayini & Ors. vs Madhavan	 AIR 1982 Kerala 126	 to enlarge the period for making the deposit so as to make it identical with that prescribed for making the appli cation	 and such extended period would have better served the object of the amendment	 namely	 ameliorating the plight of the judgment debtor	 but such are matters exclusively within the domain of legislation by Parliament and the Court cannot presume deficiency and supply the omission. The legislature did not do more than what it did. It has	 in our view	 accomplished what it had set out to achieve. No more no less. In the circumstances	 we hold that the correct construc tion of Rule 92(2) of Order XXI of the Civil Procedure Code	 1908 leads to the irresistible conclusion that the time for making a deposit in terms of Rule 89 of Order XXI is 30 days	 and Article 127 of the prescrib ing the period for making an application under Rule 89 has no relevance to the prescribed time for making the deposit. 490 Neither provision has any effect on the other as to time. All decisions the contrary on the point	 we hold	 are incorrect. With the greatest respect	 we disagree with the contrary view expressed in Basavantappa vs Gangadhar Narayan Dharwadkar & Anr.	 ; On the question of limitation the judgment of the High Court is set aside	 and the appeal is allowed to that ex tent. We make no order as to costs. R.N.J. Appeal allowed.

In this appeal by special leave brought by the auction purchaser against the Judgment of the Madras High Court the sole question for consideration is as regards the period of limitation for making a deposit to make an application under Rule 89 of Order XXI of the Civil Procedure Code	 1908 to set aside the sale of immovable property sold in execution of a decree. Whether the deposit is to be made within 30 days from the date of the sale as required by sub rule (2) of Rule 92 of Order XXI or within 60 days from the date of sale as provided in Article 127 of the ? Following its earlier decision in Thangammal & Ors. vs V.K. Dhanalakshmi & Anr. and the decision of this Court in Basavantappa vs Gangadhar Narayan Dharwadkar & Anr.	 the High Court had held that Article 127 governed the period of limitation to make a deposit in terms of Rule 89. Setting aside the judgment of the High Court on the question of limitation	 this Court in allowing the appeal	 HELD: The correct construction of Rule 92(2) of Order XXI of the Civil Procedure Code	 1908 leads to the irresist ible conclusion that the time for making a deposit in terms of Rule 89 of Order XXI is 30 days	 and Article 127 of the prescribing the period for making an application under Rule 89 has no relevance to the prescribed time for making the deposit. Neither provision has any effect on the other as to time. [489G H; 490A] Basavantappa vs Gandadhar Narayan Dharwadkar & Anr.	 ; 	 over ruled.
