But changes were made and the provisions of the new Act in this regard were drafted in pari materia with those of the old Act ; (iii) The language used in clause (d) of the proviso to S.10(2) (xiv) and S.35(2) (iv) again is significantly different from the language used in various other provisions of the Act which, in like contexts of possible double allowances, emphatically rule out deductions in respect of the same expense or exemptions in respect of the same income under two different provisions for the same or even any other assessment year : See, for example, Sections 20(2) 35B(2), 35C(2), 35CC(4), 35CCA(3), 35CCB(3), 35D(b), 35E(8), 80GGA(4), 80HH(9A), 80HHA(7) and 80HHB(S); and (iv) When the relevant provisions say that depreciation shall not be allowed in certain previous years, it permits a disallowance only in those previous years and means, by necessary implication, that it shall be allowed in other years, if otherwise eligible on the language of the provision for depreciation.
