Summarize the following court judgment. ivil Appeal No. 565 of 1976. 629 From the Judgment and Order dated 5.8.1975 of the Bombay High Court in Special Civil Application No	 429 of 1970. K. Rajgopal	 pardeep Rajgopal	 Ms. Rekha Rajgopal M.S. Ganesh and section Sukumaran for the Appellant. Dr. V. Gauri Shankar	 M. Arora and Ms. A. Subhashini for the Respondent	 The Judgment of the Court was delivered by KULDIP SINGH	 J. The appellant company carries on the business of exporting manganese ore to England and United States of America. The Income Tax Officer	 Nagpur issued a notice dated March 20	 1970 under Section 148 of the Income Tax Act	 1961 (hereinafter called the 'Act ') stating that he had reasons to believe that the income of the appellant chargeable to tax for the assessment year 1953 54 had es caped assessment within the meaning of Section 147 of the Act. The company was called upon to show cause why it should not be re assessed to. income for the said year. The appel lant company challenged the notice by way of writ petition under Article 226/227 of the Constitution of India before the Nagpur bench of the Bombay High Court. The High Court by its judgment dated August 5	 1975 dismissed the writ peti tion with costs. This appeal via special leave petition is against the said judgment of the High Court. The relevant facts are hereinafter. The appellant: is a non resident company having its office in London. It has its office in India at Nagpur. The appellant is assessed to income tax at Nagpur and it has been the practice of the 	appellant company to produce before the Income Tax Officer the relevant books which are kept by the local office at Nagpur	 the balance sheets	 the trade account and the prof it/ loss account from their head office in London. It ap pears that sometime in 1958 the customs authorities came to know that the appellant company had declared very low prices in respect of all the consignments of manganese ore exported by them out of India. It was also found that most of the export was only to three buyers who in turn did not purchase manganese ore from any other company except the appellant. After due enquiries investigation the custom authorities found that the appellant was systematically showing lesser value for the manganese ore exported as com pared with the prevailing market price for the same grade of manganese ore. 630 The Collector	 Customs	 Visakhapatnam	 by an order dated March 2	 1959 held that there was under invoicing by the appellant to. the tune of Rs.78 lacs. The said order of the collector was	 however	 set aside in appeal and the matter was remanded to the Collector for re hearing. In the final order passed by the Collector of Customs dated November 16	 1972	 under invoicing was shown to the tune of about Rs.44/45 lacs. It is thus obvious that the custom authori ties came to the conclusion that the prices mentioned in the relevant contracts between the appellant and the buyers were lesser than the contemporaneous market prices. The custom authorities thus found as a fact that the appellant company was indulging in under invoicing. The Income Tax Officer	 on coming to know about the pendency of proceedings before the Collector of Customs	 issued a notice dated March 20	 1970 under Section 148 of the Act. In the notice the reasons on the basis of which he entertained the necessary belief as required under Section 147 of the Act	 were not given	 however	 alongwith the return filed on behalf of the revenue before the High Court	 the reasons which led to the issue of notice under Section 148 on the grounds mentioned under Section 147(a) of the Act were disclosed. It is not disputed that the reasons need not be set out in the notice and the same can be produced before the court. Section 147 of the Act provides for assessment or re assessment in cases where income has escaped assessment. The Revenue 's right to take action under the section is subject to the conditions laid down therein. The requisite condi tions provided under Section 147(a) at the relevant time were as under: The income tax officer should have reason to believe that income has "escaped assess ment" by reason of omission or failure on the part of the assessee: (i) to make return of his income under the relevant provisions of the Act; or (ii) to disclose fully and truly all material facts necessary for his assessment for the year. SeCtion 147(b) of the Act on the other hand required that 'the Income Tax Officer should have	 in consequence of information in .his possession reason to believe that income has "escaped assessment". 631 It is not disputed in the year 1970 the Income Tax Officer had no jurisdiction to issue notice under Section 148 on the grounds contained under Section 147(b) of the Act as the period of limitation for the issue of such notice provided under the Act had expired. There was however no bar at that point of time to issue the said notice on the grounds under Section 147(a) of the Act. Mr. V. Rajagopal	 Senior Advocate	 learned counsel for the appellant has contended that the Income Tax Officer could not have reason to believe that there was omission or failure on the part of the appellant to disclose fully and truly all material facts necessary for the assessment and that 'the income chargeable to tax had escaped assessment. According to him	 it was not the practice with the appellant to produce the account books from their head office in London before the Income Tax Officer. The appellant company produced before the Income Tax Officer the balance sheets	 profit and loss account and all other necessary records required for the purpose of assessment. According to the learned counsel the only material before the Income Tax Officer was the original order of the Collector of Customs wherein it was held that the appellant had indulged in under invoicing	 resulting in declaring lesser price than the prevailing market price. The learned counsel contended that the order of the Collector could at the most be an information within the ambit of Section 147(b) of the Act but it could not be the basis or the reason to entertain the belief as requires under Section 147(a) of the Act. The only question which arises for our consideration is whether the two conditions required to confer jurisdiction on the Income Tax Officer under Section 147(a) of the Act have been satisfied in this case. The first is that the Income Tax Officer must have reason to believe that the income chargeable to income tax had been under assessed and the second that Such under assessment has occurred by reason of omission or failure on the part of the assessee to dis close fully and truly all material facts necessary for its assessment for the year 1953 54. So far as the first condition is concerned	 the Income Tax Officer	 in his recorded reasons	 has relied upon the fact as found by the Custom Authorities that the appellant under invoiced the goods he exported. It is no doubt correct that the said finding may not be binding upon the Income Tax Authorities but it can be a valid reason to believe that the chargeable income has been under assessed. The final outcome of the proceedings is not relevant. What is relevant is the existence of reasons to make the Income Tax Officer believe that there 632 has been under assessment of the assessee 's income for a particular year. We are satisfied that the first condition to invoke the jurisdiction of the Income Tax Officer under Section 147(a) of the Act was satisfied. As regards the second condition the appellant did not produce the books of accounts kept by them at their head office in London nor the original contracts of sale which were entered into at London with the buyers. The appellant did not produce before the income Tax OffiCer any of the accounts which related to the foreign buyers. No reasons Were given for the supply of manganese ore at a lower than the market rate. It is for the assessee to disclose all the primary facts before the Income Tax Officer to enable him to account the true income of the assessee. The proven charge of under invoicing per se satisfy the second condition. The appellant 's assessable income has to be determined On the basis of the price received by it for the goods exported. If the true price has not been disclosed and there was underin voicing the logical conclusion prima facie is that there has been failure on 'the part of the appellant to disclose fully.and truly all material facts before the Income Tax Officer. We are therefore	 satisfied that both the condi tions required to attract the provisions of Section 147(a)have been complied with in this case. Mr. V. Rajagopal further argued that in fact the notice was issued under Section 147(b)of the ACt and not under Section 147(a) of the Act. We are unable to accept this contention. Although the notice only mentioned Section 147 of the Act without indicating whether it was under Section 147(a) or 147(b)	 but the reasons recorded by the Income Tax Officer on February 26	 1970 which run into more than 20 pages specifically state that the proposed action was under Section 147(a) of the Act. Even otherwise we are satisfied that the material on the record and the reasons recorded by the Income Tax Officer justify the issue of the notice under Section 147(a) of the Act. We therefore	 dismiss the appeal with costs which we quantify as Rs. 15	000. N.P.V. Appeal dis missed.

The appellant	 a non resident company	 was carrying on the business of exporting manganese ore	 and was assessed to income tax for the assessment year 1953 54. Subsequently	 on coming to know that proceedings for under invoicing were pending against the appellant before the Customs Authori ties	 the respondent	 the Income Tax Officer issued a notice under Section 148 of the Income Tax Act	 1961 to the appel lant stating that he 'had reasons to believe that the income of the appellant chargeable to	 tax for the assessment year 1953 54 had escaped assessment within the meaning of Section 147 of the Act and called upon the appellant to show cause as to why it should not be re assesseed to income. The appellant 's writ petition challenging the notice was dis missed by the High Court. In the appeal before this Court on behalf of the appel lantcompany	 it was contended that the only material before the Income Tax Officer was the original order of the Collec tor of Customs wherein it was held that the appellant had indulged in under invoicing	 resulting in declaring lesser price than the prevailing market price	 which could at the most he an information within the ambit of Section 147 of the Act	 but could not be the basis or the reason to enter tain the belief	 as required under Section 147(a) of the Act and that the notice had been issued under Section 147(b) and not under Section 147(a). Dismissing the appeal	 this Court	 HELD: 1.1 Two conditions are required to confer juris diction on the Income Tax Officer under Section 147(a) of the Income Tax Act	 1961. The first is that the Income Tax Officer must have reason to. 628 believe that the income chargeable to income tax had been underassesseed and the second that such under assessment has occurred by reason of omission or failure on the part of the assessee to disclose fully and truly all material facts necessary for its assessment for the year 1953 54. [631F] 1.2 In the instant case	 the Income Tax Officer in his recorded reasons	 has relied upon the facts as found by the Customs Authorities that the appellant under invoiced the goods he exported. Though the said finding may not be bind ing upon the Income Tax Authorities	 it can be a valid reason to believe that the chargeable income has been under assesseed. The final outcome of the proceedings is not relevant. There should be existence of reasons to make the Income Tax Officer believe that there has been under assess ment of the assessee 's income for a particular year. Thus	 the first condition was satisfied. Secondly	 the appellant company did not produce the books of accounts kept by it at its head office located outside the country	 nor the origi nal contracts of sale which were entered into with the buyers at that place	 or .any of the accounts which related to the foreign banks. No reasons were given for the supply of manganese ore at lower than the market rate. It is for the assessee to disclose all the primary facts before the Income Tax Officer to enable him to account the true income of the asessee. Thus	 the proven charge of under invoicing per se satisfies the second condition. [631G H	 632A C] 1.3 The appellant 's assessable income has to be deter mined on the basis of the price received by it for the goods exported. If the true price had not been disclosed and there was under invoicing	 the logical conclusion prima facie is that there has been failure on the part of the appellant to disclose fully and truly all material facts before the Income Tax Officer. In the circumstances	 both the condi tions required to attract the provisions of Section 147(a) have been complied with. [632D] 2. Although the notice only mentioned Section 146 of the Act without indicating whether it was under SUb Section(a) or Sub. Section (b) the reasons recorded by the Income Tax Officer specifically state that the proposed action was under Section 147(a)i of the Act. Even otherwise	 the material on record and the reasons recorded by IncomeTax Officer justify the issue of the notice under Section 147(a) of the Act. [632F]
