Summarize the following court judgment. Civil Appeal No. 1700 (NT) of 1974. From the Judgment and Order dated 23.9.1972 of the Allahabad High Court in Writ No. 2956 of 1972. S.K. Dhingra for the Appellant. M.K. Banerjee	 Additional Solicitor General	 Miss A. Subhashini and B.B. Ahuja for the Respondent. The appellant is a private limited company carrying on the business of the manufacture and sale of locks used in suit cases. It filed a return of its income for the assessment year 1963 64 and was assessed to income tax by an assessment order dated March 12	 1968. No claim was made by the assessee for rebate under section 84 of the Income Tax Act	 1961. There was an appeal by the assessee to the Appellate Assistant Commissioner of Income Tax but no claim was made for rebate at that stage either. Subsequently on August 20	 1969 the appellant made an application under section 154 of the Income Tax Act praying for rectification of the assessment order by the grant of relief under section 84 of the Act. The application was rejected by the Income Tax Officer. A revision application moved by the appellant before the Commissioner of Income tax was also rejected on March 6	 1972. Against the order of the Commissioner the appellant now filed a writ petition in the High Court of Allahabad. The High Court dismissed the writ petition on September 23	 1972. And now this appeal by special leave. Section 84 of the Income Tax Act	 as it stood at the relevent time	 provided that income tax would not be payable by an assessee on so much of the profits and gains derived from any industrial undertaking to which the section applied as did not exceed 6 per cent per annum on the capital employed in such undertaking computed in the prescribed manner. The section applied to an industrial undertaking which satisfied certain conditions detailed in the section. It may be observed that section 84 was deleted with effect from April 1	 1968 and now finds place as section 80J in the Act. 226 The appellant contends that the Income tax authorities were obliged to exercise the jurisdiction conferred by section 154 of the Act and grant relief to the appellant under section 84. Section 154 empowers the Income Tax Officer to rectify any mistake apparent from the record and for that purpose to amend an assessment order passed by him. It is urged that the income tax authorities and the High Court erred in holding that no mistake was apparent from the record merely because no claim to relief under section 84 had been made by the appellant before the Income Tax officer during the assessment proceedings. It is contended that an obligation was imposed on the Income Tax Officer by the statute to grant such relief and it could not be refused merely because the appellant had omitted to claim the relief. While we believe the appellant is right in his contention	 we do not think that the mere existence of such an obligation on the Income Tax Officer is sufficient. Before the Income Tax Officer can grant relief there must be clear data on the assessment record sufficient to enable him to consider whether the relief should be granted. In the absence of such material	 no fault can be found with the Income Tax Officer for not making an order under section 84 favouring the assessee. It will be noticed from the provisions of section 84 that several conditions must be satisfied before the grant of relief can be considered. The industrial undertaking should not have been formed by the splitting of	 or the reconstruction of	 a business already in existence. It should not have been formed by the transfer to a new business of a building	 machinery or plant previously used for any purpose. It should manufacture or produce articles in any part of India	 which manufacture or production should have begun at any time within 23 years next following April 1	 1948 or such other further period as the Central Government may specify. An industrial undertaking manufacturing or producing articles should be found to employ 10 or more workers in a manufacturing process carried on with the aid of power or to employ 20 or more persons in a manufacturing process carried on without the aid of power. These are some of the conditions which need to be fulfilled before relief under section 84 can be granted. It is apparent that precise factual material must be contained in the record in order to enable the Income Tax Officer to discharge his obligation to grant relief under section 84. It has not been shown to us that the record before the Income Tax Officer contained all that information. Our attention was drawn to Subhash Chandra Sarvesh Kumar vs Commissioner of Income tax and Another	 where the Allahabad High Court quashed an order of the Commissioner of 227 Income tax rejecting revision applications for the grant of relief under section 80J and section 80HH of the Income Tax Act	 on the ground that the Commissioner should have considered whether there was material on the record to sustain the claim of the assessee to relief	 and the fact that claim was not made formally in the return or during the pendency of the assessment proceedings before the Income Tax Officer should not have prevented the Commissioner from considering whether the assessee was entitled to relief. That was a case where the assessee complained in the writ petition that it lay within the jurisdiction of the Commissioner to entertain the claim of the assessee even though the claim had not been made before the Income Tax officer. The present is a case	 however	 where the appellant sought to invoke the jurisdiction of the Income Tax Officer to rectify the assessment order. That can only be justified on the ground of a mistake apparent from the record. If the record does not contain any material	 it cannot be said that the Income Tax Officer has committed a mistake in omitting to grant relief under section 84. We are conscious that the jurisdiction under section 154 of the Income Tax Act is	 as pointed out by this court in Income tax Officer	 Alwaye vs Asok Textiles Ltd.	 	 wider than that provided under rule 1 of Order XLVII of the Code of Civil Procedure. Rule 1 of Order XLVII of the Code confines the jurisdiction of the Court to the rectification of "an error apparent on the face of the record" while section 154 of the Income Tax Act	 1961 (which corresponds to section 35 of the Income Tax Act 1922) uses wider language and empowers the Income tax authorities to rectify any mistake "apparent from the record". Nonetheless there must be material to support the claim to relief under section 84	 and unless such material can be referred to no grievance can be made if the Income Tax Officer refuses to rectify the assessment and refuses relief under section 84. Learned counsel for the appellant says that the material is contained in the record of the assessment made on the appellant under the . He contends that the record of the Super Profits Tax assessment must be regarded as an integral part of the record of the income tax assessment and	 therefore	 it must be inferred that the material necessary for granting relief under section 84 in the income tax assessment lay before the Income Tax Officer. The was enacted to impose a special tax on certain companies. The tax is charged on the excess of the chargeable profits of a company over the standard deduction and the "chargeable profits"	 according to the definition in sub section (5) of section 2 of 228 that Act	 means the total income of an assessee computed under the Income Tax Act	 1961 adjusted in accordance with the provisions of the First Schedule. In many respects	 the borrows its provisions from the Income Tax Act	 and the scheme for assessment	 appeals	 revision and rectification in the follows closely the pattern set forth in the Income Tax Act. As has been noted the computation of chargeable profits turns on the computation of the total income determined under the Income Tax Act. Where any order of rectification is made under section 154 or under section 155 of the Income Tax Act recomputing the total income of an assessee	 a consequential recomputation of the chargeable profits is provided for by section 15 of the . Moreover	 the Super Profits Tax payable by a company for the assessment year is deductible from the total income of the company for that assessment year in computing the distributable income of a company for the purposes of section 104 and section 105 of the Income Tax Act. There is undeniably a close relationship between the and the Income tax Act and any change in the assessment made under the Income Tax Act has its consequential impact on the assessment made under the . It is apparent therefore	 that the record of an income tax assessment can be regarded as part of the record of a Super Profits Tax assessment. The converse can also be true that is made abundantly clear by sub section (2) of section 20 of the which provides that all the information contained in any statement or return made or furnished under the provisions of the or obtained or collected for the purposes of that Act may be used for the purposes of the Income Tax Act. To the extent that information contained in the Super Profits Tax record is employed for the purpose of the Income Tax proceeding	 it cannot be doubted that the Super Profits Tax record becomes part of the Income Tax record. It is apparent that if the record of the Super Profits Tax assessment contains material pertaining to the claim under section 84 of the Income Tax Act	 such material can be considered by the Income Tax Officer for the purpose of granting relief under section 84 in the Income Tax assessment. In that sense and to that degree learned counsel for the assessee is perfectly right in contending that the record of the Super Profits Tax assessment becomes part of the record of the Income Tax assessment. That does not suffice	 however	 to entitle the assessee to relief. As has been mentioned earlier	 there are a number of conditions which must be satisfied before relief can be granted under section 84. All that data was evidently not contained in the Super Profits Tax assessment record at the time when the Income Tax assessment was completed. The 229 Additional Commissioner of Income Tax	 while dismissing the revision petition of the assessee against the order of the Income Tax Officer refusing to rectify the Income Tax assessment under section 154	 went through the Income Tax record and the Super Profits Tax record of the assessee and found that no attempt had been made at any stage by the assessee to place facts on the record indicating that the undertaking belonging to the assessee was a new one and was entitled to relief under section 84. He noted that in the return relating to the the assessee had made a claim for relief under section 84	 but he pointed out that the claim had not yet been examined. It has also not been shown to us that all the material required for satisfying the conditions requisite for the grant of relief under section 84 existed on the Super Profits Tax record at the time when the income tax assessment was completed. When that is the position	 it can hardly be said that in omitting to grant relief under section 84 when making the assessment order the Income Tax Officer committed a mistake apparent from the record. We must remember that we are dealing with a challenge to an order refusing rectification and not to an order directly assailing the assessment. In the result	 the appeal fails and is dismissed with costs. P.S.S. Appeal dismissed.

Section 84 (now redesignated as section 80J) of the Income tax Act	 1961 as it stood at the relevant time	 provided that income tax would not be payable by an assessee on so much of the profits and gains derived from an industrial undertaking to which the section applied as did not exceed six per cent per annum on the capital employed in such undertaking computed in the prescribed manner. Several conditions laid down therein had to be satisfied before the grant of relief could be considered. Section 154 empowers the Income tax Officer to rectify any mistake apparent from the record and for that purpose to amend an assessment order. The appellant who did not make a claim for rebate under section 84 either during the assessment proceedings or at the appeal stage subsequently made an application to the Income tax Officer under section 154 praying for rectification of the assessment order by grant of relief under section 84	 which was rejected. The revision sought before the Commissioner also failed. The writ petition filed before the High Court having been dismissed	 the appeal by special leave was preferred. It was contended: (1) that an obligation was imposed on the Income tax officer by the statute to grant relief which could not be refused merely because the appellant had omitted to claim the same	 and (2) that the record of the super profits tax assessment containing the material	 which lay before the 224 Income tax Officer	 must be regarded as an integral part of the record of the income tax assessment for granting relief under section 84. Dismissing the appeal	 the Court	 ^ HELD: Rectification could only be justified on the ground of a mistake apparent from the record. If the record did not contain any material	 it could not be said that the Income tax Officer had committed a mistake in omitting to grant relief under section 84. [227C D] Although the jurisdiction under section 154 to rectify any mistake apparent from the record is wider than that provided under r. 1 of Order XLVII of the Code of Civil Procedure to rectify an error apparent on the face of the record	 nonetheless there must be material to support the claim to relief under section 84	 and unless such material can be referred to	 no grievance can be made if the Income tax Officer refuses to rectify the assessment and refuses relief under section 84.[227D F] There is a close relationship between the Super Profits Tax Act and the Income Tax Act	 and any change in the assessment made under the latter has its consequential impact on the assessment made under the former. The converse is equally true	 especially in view of section 20(2) of the Super Profits Tax Act which provides that all the information contained in any statement or return made or furnished under the provisions of that Act or obtained or collected for the purpose of that Act may be used for the purpose of the Income Tax Act. Therefore	 if the record of the super profits tax assessment contains material pertaining to the claim under section 84 of the Income tax Act	 such material can be considered by the Income tax Officer for the purpose of granting relief under section 84 in the income tax assessment.[228D G] In the instant case	 the appellant has failed to show that all the material required for satisfying the conditions requisite for the grant of relief under section 84 existed on the super profits tax record at the time when the income tax assessment was completed. Therefore	 it cannot be said that in omitting to grant relief under section 84 when making the assessment order	 the Income tax Officer committed a mistake apparent from the record.[229C D] Subhash Chandra Sarvesh Kumar vs Commissioner of Income tax and Another	 and Income tax Officer	 Alwaye vs Asok Textiles Ltd.	 	 referred to. 225
