Summarize the following court judgment. ivil Appeal Nos. 948 950 of 1975. From the Judgment and order dated 12.9.1974 of the High Court of Patna in Tax Case Nos. 2 to 4 of 1968. Harish N. Salve	 Mrs. A.K. Verma	 Ms. section Sethna and Joel Peres for the Petitioner. D. Goburdhan for the Respondent. The Judgment of the Court was delivered by RANGANATHAN	 J. These three appeals by the Fertiliser Corporation of India Limited (hereinafter referred to as 'the asses see ') arise out of its sales tax assessments for the assessment years 1959 60	 1960 61 and 1961 62 under the Bihar Sales Tax Act	 1959	 (hereinafter referred to as 'the Act '). They raise a very short but interesting question. regarding the entitlement of the assessee to the rebate of tax provided for in section/5 of the Act. At the outset	 a reference may be made to the salient portions of certain relevant provisions of the Act. Section 14(1) provides that every registered dealer shall furnish such returns within such period and to such authority as may be prescribed. The prescribed authority is the Assistant Commissioner of Sales Tax who is also the assessing authority. Under rule 10 of the Rules framed under the Act	 the assessee should file quarterly returns. Such returns are to be filed within one calendar month of the expiry of the period to which they relate. Sub section (3) of section 14 provides for an extension of time for the filing of the return. It reads: "If the prescribed authority is satisfied that a dealer is	 for reasonable cause	 unable to furnish any return within the prescribed period or the period fixed under the proviso to sub section (1)	 the said authority may extend the period for submission of the return." Section 20 of the Act requires that	 before any registered dealer furnishes a return under the Act	 he should pay into a Government Treasury the full amount of tax due under the Act according to such return and should also furnish along with the return a receipt from such Treasury showing the payment of the said amount. section 15 is the 151 provision entitling the assessee to a rebate. It reads as follows: "Rebate A rebate at the rate of one per centum of the amount of tax admitted to be due in the return furnished under sub section (1) of section 14 in the prescribed manner and within the prescribed or extended period shall be allowed to a registered dealer who has paid such amount according to the provisions of sub section (2) of section 20. Provided that where the amount finally assessed on the dealer is less than the admitted amount	 rebate at the said rate shall be allowed only on the amount so assessed: C Provided further that the State Government may	 by notification	 and subject to such conditions or restrictions as may be specified therein	 enhance or reduce the rate of rebate in respect of registered dealers generally or any class of such dealers " It may be noted that	 under the proviso to section 22 of the Act	 a registered dealer is entitled to deduct from the amount of tax due from him under the Act according to his return any amount which may be admissible as rebate under the provisions of section 15. In the present case	 the assessee filed its quarterly returns under section 14(1) of the Act but	 except for the second quarter of 196061	 the returns were all filed belatedly. To illustrate	 the returns for the second	 third and fourth quarters of 1959 60	 were filed by the assessee only on the 7th November	 1959	 11th February	 1960 and Ist June 1960. In other words	 the returns were late by a few days. It is common ground that there was no application made by the assessee to the prescribed authority for extension of the time prescribed under the Act for the filing of the return. The assessee however	 paid the taxes before the due dates of the respective returns	 availed itself of the rebate and deducted the same while paying the tax due on the returns filed by it. The short question that arose before the Tribunal as well as the High Court was whether the assessee was entitled to the rebate under section 15. The Tribunal held that the rebate is available to an assessee only if 152 (i) the tax on the basis of returns is paid as prescribed in section 20; and (ii) the quarterly returns of the assessee ha d been filed within the prescribed period or extended period. As the assessee had not filed its returns within the prescribed period and	 since the assessee had sought no extension	 it was held that the assessee was not entitled to the rebate. The assessee sought for a reference and	 before the High Court	 relied on a decision of the same High Court in Jamuna Flour & oil Mills Pvt. Ltd. vs State of Bihar	 [1968] 22 S.T.C. 1. The facts of the case were similar to those of the present case and the assessee had been held entitled to the rebate. It is sufficient to extract the relevant portion of the head note: "For the quarter ending 30th June	 1961	 the assessee had paid the tax due before 31st July	 1961	 but it actually filed the return only on Ist August	 1961. The assessee was assessed on the basis of the return submitted by it but its claim for rebate under section 15 of the Bihar Sales Tax Act	 1959	 was rejected by the taxing authority on the ground that for the purpose of eligibility for rebate under section 15	 the assessee must fulfil two conditions	 viz.	 (1) the tax due for the quarter must be paid before the end of succeeding month	 and (2) the return must also be filed by the end of the succeeding month: Held	 that the assessee was entitled to the rebate under section 15 for the quarter ending 30th June	 1961. Although the return was submitted one day late	 as the assessee was assessed not under the best of judgment principle but on the return submitted by it	 it must be said that	 impliedly the period for furnishing the return was extended by one day as permitted by section 14(3). The passing of an express order by the taxing authority	 regarding its satisfaction about the existence of reasonable cause for failure to furnish the return by 31st July 1961	 was not necessary. on a proper construction of section 15 read with section 20	 the eligibility for claiming rebate arises if the amount is paid under section 20(2). That portion of 153 section 15	 which refers to the filing of return within the prescribed period	 should not be construed as a condition for a right to claim rebate. The reference to the return in section 15 is for the purpose of ascertaining the amount of tax admitted to be due and it is not meant to restrict the assessee 's right to claim rebate. " The two judges who heard the case of the assessee were divided in their opinion on the question at issue. The matter was	 therefore	 referred to a larger bench. This Bench (by a majority of 2 to 1) took the same view as Tribunal. The assessee is in appeal before us	 convassing the correctness of the decision of the Full Bench. We have given careful thought to the contentions of the counsel tor the parties and the differing views expressed by the Judges who heard the above two cases. We have reached the conclusion that the view taken by the High Court in Jamuna Flour and oil Mills (Pvt.) Ltd. vs State of Bihar	 [1968] 22 S.T.C. 1	 is the better view on a proper construction of the relevant statutory provisions. The object of section 15 of the Act is to confer a benefit on an assessee for prompt payment of the tax. In this case there is no dispute that the assessee had paid the tax before the due dates. There is also no dispute that the tax paid accords with the tax due on the basis of returns. The only question is whether the assessee should be penalised by being denied the rebate due to it because there was a short delay in the filing of the returns. The argument on behalf of the Revenue which has appealed to the High Court is this. Section 15 is not a taxing provision but one which confers a benefit or concession to assessee. Settled principles of construction of taxing statutes require that such conditions should be strictly construed. The section lays down two conditions for the grant of benefit or concession of which one is not fulfilled. Though the assessee had paid the taxes in time	 it had neither filed returns within the prescribed time nor cared to obtain an extension for filing the same. There is no reason why such an assessee should be shown any leniency and given a benefit which it does not deserve on the language of the statute. Granting the correctness of the above argument and assuming that it is also a condition precedent for the grant of rebate that the assessee should have filed its return within the prescribed or extended period	 we think it can be said that the said condition is fulfilled 154 in the present case. The return was admittedly not filed within the time prescribed under section 14(1). Has it been filed	 then	 within the extended period? In answering this question	 certain features of the Act have to be kept in mind. The first is that the Act does not set out any particular procedure for obtaining extension of time. It does not prescribe any form of application. It does not say that such application must be filed before the expiry of the prescribed period. It does not require that the prescribed authority must pass an order recording his satisfaction that the time should be extended and granting time. The second is that	 under the provisions of the Act three consequences are envisaged where a return is not filed within the prescribed time or extended time: (i) the assessee will lose the benefit of rebate under section 15; (ii) the assessee will run the risk of a penalty under section 14(4); (iii)the assessee will also run the risk of a best judgment assessment under section 16(4). In the present case	 the assessing authority has neither levied a penalty nor made a best judgment assessment. The assessment orders	 while adverting to the delay in the filing of the returns	 do not record a finding that the delay was without reasonable Cause. These are circumstances from which	 we think	 it is reasonable to infer that the returns	 though filed belatedly	 have been accepted and acted upon by the prescribed authority. We see no reason why an extension of time cannot be inferred from the attendant circumstances in this case. Learned counsel for the assessee also suggests a different kind of approach to the issue before us. He submits that all that section 15 aims at is to grant a tax rebate of 1% of the amount of tax admitted to be due as per the return filed by the assessee. The further words used in section 15 to describe the return	 namely	 that it should be a return filed in the prescribed manner and within the prescribed or extended period are merely words descriptive of the procedure of filling a return. The basic condition necessary for claiming the tax rebate is only that there should be a valid return and that the tax on the basis of the valid return should have been paid by the assessee. He submits that while the substantive part of the condition should be strictly construed by insisting upon the presence of a valid return	 the procedural aspect referred to can well receive a liberal construction. In the present case	 he points out	 there is no dispute that the returns 155 filed by the assessee were valid. In fact the assessments have been made on the basis of the returns filed. The tax has been paid even before the submission of the returns. There is no suggestion that the tax paid fell short of the tax due on the return. This is also not a case where the assessed tax is much higher than the tax admitted on the basis of the return. In these circumstances	 he argues	 the assessee must be held to have fulfilled the conditions prescribed in section 15. Learned counsel for the assessee referred to certain decisions in support of such a rule of construction. In C.I. T. vs Kulu Valley Transport Co. Pvt. Ltd.	 [1970] 77 I.T.R. 518 the court had to construe a provision intended to benefit the assessee. Under section 22 (2A) of the Income Tax Act	 1922	 a return of loss had to be filed within the time prescribed for return under section 22(1) if the assessee wanted to carry forward the loss claimed. It was not so filed but was nevertheless treated as a valid return by reading the provisions of section 22(1) and 22(3) of the Act jointly and giving a liberal interpretation to section 22(2A). In the case of Gursahai Saigal vs C.I.T.	 [1963] 48 I.T.R. S.C. 1 the question was regarding the charge of interest section 18A(8) of the same Act. This provision did reveal a lacuna but reading the provision along with section 18A(6)	 the Court gave effect to the intendment of the Legislature. It was explained that section 18A(8) was not a provision creating a charge of tax but only laying down the machinery for its calculation or procedure for its collection. The dictum of Scott L.J. in Allen vs Trehearne	 that machinery provisions should be interpreted largely and generously in order not to defeat the main object of liability laid down by the statute was referred to. The following observations of the Privy Council in C.I.T. vs Mahaliram Ramjidas	 were also relied upon: "The section	 although it is part of a taxing Act	 imposes no charge on the subject	 and deals merely with the machinery of assessment. In interpreting provisions of this kind the rule is that that construction should be preferred which makes the machinery workable. " Though the above decisions arose under a different enactment and on different statutory language	 they dealt with somewhat analogous situations and furnish useful guidance here. They do lend support to the assessee 's contention. It does seem that the condition in section 15 referring to a return has a substantive as well as procedural content and it may not be inappropriate to construe the latter 156 somewhat liberally and generously so long as the principal object of the provision is not frustrated. For these reasons	 we are of the opinion that the High Court should have answered the question	 as re framed by it	 in the negative and in favour of the assessee. We approve the decision in Jamuna Flour & oil Mills Pvt. Ltd. vs State of Bihar	 [1968] 22 S.T.C. 1 and reverse the decision in the present case. The appeal is allowed. But	 in the circumstances of the case	 we make no order as to costs. P.S.S. Appeal allowed.

% Section 14(1) of the Bihar Sales Tax Act	 1959 requires dealers to furnish returns within such period and to such authority as may be prescribed. Rule 10(2) of the Bihar Sales Tax Rules	 1959 requires the assessee to file quarterly returns within one calendar month of the expiry of the period to which they relate. Sub section (3) of section 14 provides for extension of time for submission of the return. Subsection (2) of section 20 requires dealers to pay into the Government Treasury the full amount of tax due and furnish a receipt along with the return. Section 15 entitles the assessee to rebate in tax on returns furnished under sub section (1) of section 14 or within extended period. The proviso to sub section (2) of section 20 entitles a dealer to deduct from the amount of tax due from him any amount which may be admissible as rebate under the provisions of section 15. The assessee filed its quarterly returns under section 14(1) of the Act late by a few days. There was no application made by it to the prescribed authority for extension of time. The assessee	 however	 paid the tax before the due date of the respective returns and availed itself of the rebate by deducting the same while paying the tax due. The Tribunal held that as the assessee did not file its returns within the prescribed period and had sought no extension	 it was not entitled to the rebate. The High Court upheld the view taken by the Tribunal. Allowing the appeal	 149 ^ HELD: 1. The assessee was entitled to the rebate of tax provided for in section 15 of the Bihar Sales Tax Act	 1959. [156B] 2. The condition in section 15 referring to a return has a substantive as well as procedural content. The latter should be construed somewhat liberally and generously so long as the principal object of the provision is not frustrated. [155H; 156A] C.I.T. vs Kulu Valley Transport Co. Pvt. Ltd.	 ; Gursahai Saigal vs C.l. T. [1963] 48 I.T.R. S.C. 1; Allen vs Trehearne	 and C.I.T. vs Mahaliram Ramjidas	 referred to. 3.1 The object of section 15 of the Act is to confer a benefit on an assessee for prompt payment of the tax. In the instant case	 the assessee had paid the tax before the due dates. The tax paid accords with the tax due on the basis of returns. There was short delay only in the filing of the returns. [153D E] 3.2 The Act does not set out any particular procedure for obtaining extention of time. It does not prescribe any form of application. It does not require that the prescribed authority must pass an order recording his satisfaction that the time should be extended and granting time. it envisages three consequences to the assessee for failure to file a return within the prescribed time	 or extended time: (i) loss of rebate under section 15	 (ii) risk of a penalty under section 14(4)	 and (iii) risk of a best judgment assessment under section 16(4). [154A D] 3.3 In the instant case the assessing authority has neither levied a penalty nor made a best judgment assessment nor recorded a finding that the delay was without reasonable cause. From these circumstances it is reasonable to infer that the returns	 though filed belatedly	 have been accepted and acted upon by the prescribed authority. An extention of time can thus be inferred from the attendant circumstances of the case. [154D F] 3.4 The condition precedent for the grant of rebate that the assessee should have filed its return within the prescribed or extended period	 can	 therefore	 be said to have been fulfilled in the present case. [153H; 154A] Jamuna Floor & oil Mills Pvt. Ltd. vs State of Bihar	 [1968] 22 S.T.C. 1	 approved.
