The four main lines of argument on which the respondent assessee rested his contention that the Incometax Officer concerned had no jurisdiction were these : firstly, it was urged that section 34 of the Indian Incomtax Act, 1922, was not saved by section 13(1) of the Finance Act, 1950, because what was saved was the prior law " for the purposes of the levy, assessment and collection of income tax ", which expression did not include re assessment proceedings; secondly, it was argueed that, even otherwise, the financial agreement made between the President of India and the Rajpramukh of Mysore on February 28, 1950, which received constitutional sanctity in article 278 of the Constitution rendered the impugned proceedings unconstitutional and void; thirdly, it was submitted that the Indian Income tax Act, 1922, as in force in the retroceded area stood repealed on June 30, 1948, by Mysore Act XXXI of 1948, and the saving provisions in section 5(b) thereof or in paragraph (2), sub paragraph (b), of Schedule A to Mysore Act LVII of 1948, did not save section 34 in so far as it permitted re assessment proceedings in respect of years in which there had been an assessment already; and lastly, it was contended that after June 30, 1948, and until April 1, 1950, the Income tax Officer in the retroceded area could re open 796 the assessment under section 34 of the Mysore Incometax Act, 1923, within a period of four years specified therein, but there was no authority to re open the assessment under section 34 of the Indian Income tax Act.
