....The argument before the Supreme Court was that section 26 was not applicable to a case where income was returned but was initially held to be not liable to tax. This contention was negatived and the Supreme Court held that the Agricultural Income-tax Officer was competent under section 26 of the Bihar Act to assess an item of income which he had omitted to tax earlier, even though in the return that income was included and the Agricultural Income-tax Officer then thought it was exempt. In paragraph 16 of its judgment the Supreme Court pointed out that the use of the words "any reason" which are of wide import dispenses with those conditions by which section 34 of the Indian Income-tax Act is circumscribed. Having regard to the manner in which section 16 is worded, the restrictions which are based upon the Income-tax Officer for reopening an assessment under section 147 cannot be imported when the validity of the action taken under section 16 is to be judged and having regard to the use of the words "for any reason" it is clear that, even where a turnover was disclosed but it was not subjected to tax, because at the relevant time, the assessing authority thought that particular turnover was exempt under the provisions of section 5(3) of the Central Act, it will be permissible for the assessing authority to reopen the assessment under section 16(1)(a) of the local Act. No infirmity can, therefore, be found in the reassessment proceedings which were either initiated or completed. 24. An argument was advanced before us that in an assessment proceeding under the Income-tax Act, 1961, it is quite possible for an Income-tax Officer, dealing with a case of the dealer, to take the view that any additional tax consequent upon the reassessment under section 16 of the Tamil Nadu General Sales Tax Act would not be treated as deductible expenditure under section 37 of the income-tax Act with the result that as a consequence of the wrong view of the law taken by the assessing authority, the petitioner would be prevented from getting the necessary relief under the Income-tax Act. According to the learned counsel the assessments made under section 16 must be held to be invalid because section 16 cannot be so construed as to take away the benefit of deduction of tax paid for purposes of the Income-tax Act. This contention must be rejected. The provision under section 16 of the Tamil Nadu General Sales Tax Act will have to be construed in accordance with the well-known rules of interpretation of statutes. What impact this reopening of assessments will have on the petitioners' rights under some other Act like the Income-tax Act will be foreign to the question of
