The question which has been referred at the instance of the assessee reads as follows.

"Whether, on the facts and in the circumstances of case, the 12-year National Defence Certificates and 10-year Defence Deposit Certificates of the value of Rs. 50, 000 held by the assessee were not entitled to exemption under the Wealth-tax Act, 1957 ?" *

The assessee in her wealth-tax assessment for the assessment year 1975-76 claimed exemption from tax with reference to agricultural lands, residential house and 12-year National Defence Certificates and 10-year Defence Deposit Certificates held by her of the total value of Rs. 50, 000. These certificates were purchased by the assessee on March 31, 1964, and March 2, 1968, respectively. The assessee had also claimed exemption from tax to the extent of Rs. 1, 50, 000 out of the value of shares held by her in various limited companies and deposits in banks. The Wealth-tax Officer rejected the assessee's claim for exemption of the value of the 12-year National Defence Certificates and 10-year Defence Deposit Certificates, though admittedly, these were held by the assessee from a date prior to March 1, 1970.

On appeal, the Appellate Assistant Commissioner, however, deleted sum of Rs. 50, 000 from the net wealth of the assessee purporting to do so under the proviso to section 5(1A) of the Wealth-tax Act. The Revenue challenged this order before the Tribunal. The Tribunal allowed the appeal holding that there was no ambiguity in section 5(lA) of the Act and it is only when items (xv) and (xvi) in section 5 of the Act themselves exceed the value of. Rs. 1, 50, 000 that the entire amount was eligible for the exemption. The order of the Appellate Assistant Commissioner was, therefore, set aside. Out of this order of the Tribunal, the question reproduced above has been referred for the decision of this courtLearned counsel for the assessee contended that under the proviso to section 5(l A) of the Wealth -tax Act as was in force at the material time in the case of the assessee, exemption from wealth-tax must be to the extent of Rs. 2, 00, 000, that is to say, the certificates in question were entitled to exemption separately in addition to the general exemption permitted to the extent of Rs. 1, 50, 000. The controversy seems to be concluded at least by three decisions against the assessee with which we are inclined to agree, because it appears to us that that is the only construction possible on a plain reading of the relevant provision.

There is no doubt that the certificates in question fall squarely in item (xvi) only. In item (xvi), in section 5(lA) of the Wealth-tax Act, it is expressly provided that nothing contained in this clause shall operate to exclude from the net wealth of the assessee any assets referred to in the clauses mentioned in that section to the extent the value thereof exceeds in the aggregate a sum of Rs. 1, 50, 000 at the material time. Certificates in item (xvi)are one of the items referred to in section 5(lA). The plain meaning of section 5(lA) of the Act, therefore, is that in respect of the assets which are specified in section 5(1A), exemption from wealth-tax is permissible only to the limit of Rs. 1, 50, 000 and anything in excess of the value of Rs. 1, 50, 000 will not be entitled to exemption. There is a proviso to section 5(lA) which reads as follows

"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 Deposits) Rules, 1959 ], which have been owned by the assessee continuously from a date prior to the 1st day of March, 1970, and the value of the 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." *

Learned counsel for the assessee wants to construe this proviso as to mean that the asset referred to in clause (xvi) is independently entitled
