JUDGMENT

HANSARIA, J. :- Leave granted in the S.L. Ps. These appeals arise out of judgments of the High Court of Kerala rendered in ITR cases Nos. 28 and 37 of 1976; 30, 60 and 63 of 1977 and 141 of 1979 by which the High Court answered the questions referred to it at the behest of the Department under the provisions of Wealth Tax Act, 1957, hereinafter the Act, in favour of the Department. On being satisfied that the questions answered by it raise a substantial question of law of general importance on which a pronouncement by this Court is necessary, it certified the cases as fit for appeal to this Court on prayer being made by the counsel of the assessee.

2. The question referred to the High Court read as follows :-

"Whether on the facts and in the circumstances of the case and on the interpretation of Section 5(1A) of the Wealth-tax Act, 1957, the Appellate Tribunal is right in law in holding that the assessee is entitled to exemption of Rs. 70,000/- invested by her in National Defence Certificates and Defence Deposit Certificates in addition to the overall exemption of Rs. 1,50,000/- granted to her by the Wealth-tax Officer, under Section 5(1) of the Act."

3. The aforesaid was the question which came up for consideration of the High Court in ITR cases 28 and 37 of 1976. Similar questions were subject matter of other cases referred above. The High Court took the view that as investment in National Defence Certificates and Defence Deposit Certificates attracted, on the facts before it, the proviso to sub-section (1A) of Section 5, exemption for the amounts in question (which was Rs. 70,000/- in the aforesaid two cases, and was below Rs. 1,50,000/- in all the cases) could not be granted over and above Rs. 1,50,000/- which was the limit prescribed by the main provision. It may be stated that investment in aforesaid certificates would have fallen in clause (xv) of sub-section (1) of Section 5 of the Act.

4. The learned counsel for the assessee has assailed the view taken by the High Court whereas the Departments counsel supports the same.

5. The controversy lies within a narrow compass and the answer depends upon the interpretation of Section 5(1A) of the Act. The material part of the section as it stood at the relevant time read as follows :-

"Nothing contained in sub-sec. (1) shall operate to exclude from the net wealth of the assessee any assets referred to in clauses (xv), (xvi), (xxii), (xxiii), (xxiv), (xxv), (xxvi), (xxvii), (xxviii), (xxix), (xxxi) and (xxxii) not being deposits under the Post Office Savings Bank (Cumulative Time Deposits) Rules, 1959, to the extent the value thereof exceeds, in the aggregate, a sum of one hundred and fifty thousand rupees :

Provided that where the assets include any assets referred to in clause (xv) or clause (xvi) not being deposits under the Post Office Savings Bank (Cumulative Time Deposit) Rules, 1959, which have been held by the assessee continuously from a date prior to the 1st day of March, 1970 and the value of assets so included exceeds the limit of one hundred and fifty thousand rupees by any amount, such limit shall be raised by the said amount." (Emphasis supplied)

6. Departments case is that as the assets referred to in the main provision of sub-section (1-A) exceeded in the cases at hand Rs. 1,50,000/- in the aggregate, the exemption limit could have been raised only if the value of assets referred to in clause (xv) or (xvi) held prior to the 1st day of March, 1970 would have exceeded Rs. 1,50,000/- . In such a case only, the limit of exemption provided by the main provision of sub-section (1A) could have been raised by the amount the assets mentioned in the proviso would have exceeded the sum of Rs. 1,50,000/-.

7. To clear the ground, it may be stated that there is no dispute before us that the net wealth of the assessee as regards the assets referred in the clauses specified in the main provision of sub-section (1A) had exceeded Rupees 1,50,000/-. Shri Ahuja, appearing for the D
