April 1, 1988 was not on the statute book when the assessments were made in the case of Allied Motors (P) Limited (supra). However, the assessee contended that even though the first proviso came to be inserted with effect from April 1, 1988, it was entitled to the benefit of that proviso because it operated retrospectively from April 1, 1984, when Section 43-B stood inserted. This is how the question of retrospectively arose in Allied Motors (P) Ltd. [1997] 224 I.T.R. 677. This Court, in Allied Motors (P) Limited [1997] 224 I.T.R. 677 held that when a proviso is inserted to remedy unintended consequences and to make the section workable, a proviso which supplies an obvious omission in the section and which proviso is required to be read into the section to give the section a reasonable interpretation, it could be read retrospective in operation, particularly to give effect to the section as a whole. Accordingly, this Court, in Allied Motors (P) Ltd. [1997] 224 I.T.R. 677, held that the first proviso was curative in nature, hence, retrospective in operation with effect from April 1, 1988. It is important to note once again that, by the Finance Act, 2003, not only the second proviso is deleted but even the first proviso is sought to be amended by bringing about an uniformity in tax, duty, cess and fee on the one hand vis-a-vis contributions to welfare funds of employee(s) on the other. This is one more reason why we hold that the Finance Act, 2003, is retrospective in operation. Moreover, the judgment in Allied Motors (P) Limited (supra) is delivered by a Bench of three learned Judges, which is binding on us. Accordingly, we hold that Finance Act, 2003, will operate retrospectively with effect from April 1, 1988 [when the first proviso stood inserted]. Lastly, we may point out the hardship and the invidious discrimination which would be
