Hansaria, J.:- These petitions are under Article 226 of the Constitution of India and are directed against the orders passed by the learned Commissioner, Wealth-Tax, under section 18 (2A) of the Wealth-Tax Act 1957, hereinafter the Act. The relevant facts are that the petitioner is a wealth-tax assessee and he submitted his wealth-tax return for the assessment years 1967-68 to 1969-70 on 11.6.73 under section 14 (1) of the Act. As the petitioner had filed his returns late, he submitted a petition on 21.6.73 to the learned Commissioner u/s. 18 (2A) of the Act for waiver of the penalty imposable under section 18(1)(a) of the Act. By the impugned order the learned Commissioner has rejected the prayer on the ground that according to him the assessee had not made full disclosure, which is one of the essential Conditions for invocation of power under the aforesaid sect­ion of law. What happened was that the petitioner in his wealth-tax return had disclosed the valuation of immovable pro­perty he owns at Ulubari, Gauhati, at Rs. 61,250/- for his half share. The learned Commissioner in his impugned order stated that the total investment in the property was to the extent of Rs. 1,45,500/-being Rs. 23,000 as purchase price of land and Rs. 1,22,500/- as construction cost of the building. Half of this comes to Rs. 72,750/-, as against Rs. 61.250/- disclosed by the assessee. Thus the learned Commissioner felt that by his own reckoning the assessee understand the valuation of his property by Rs. 11.500/-even if appreciation in the value of the properties since 1963 were to be left out of account. The return thus lacked full disclosure according to the learned Commissioner, which resulted in denial of any relief u/s. 18 (2A) of the Act. 2. The submission of Shri Bhattacharjee is that the learned Commissioner misconceived the law in having stated on the above facts that there was lack of full disclosure of the net wealth by the assessee. 3. Before proceeding further, it may be stated that at the relevant time this part of the requirement of law was that the disclosure must be in good faith and 'full'. The section unde­rwent an amendment and under the provision as it now finds place in section 18-B the disclosure must be "full and true". We are, therefore, not concerned in these cases whether the disclo­sure was ture also or not. The section unde­rwent an amendment and under the provision as it now finds place in section 18-B the disclosure must be "full and true". We are, therefore, not concerned in these cases whether the disclo­sure was ture also or not. We may read relevant part of Section 48 (2) as it existed at the material time : "(2A) Notwithstan­ding anything contained in clause (1) or clause (iii) of sub­section (1), the Commissioner may, in his discretion,- (i) reduce or waive the amount of minimum penalty imposable on a person under clause (i) of sub-section (1) for failure, without reasonable cause, to furnish the return of net wealth which such person was required to furnish under sub-section (1) of Section 14, or (ii) ** ** ** if he is satisfied that such person-(a) in the case referred to in clause (i) of this sub-section has 'prior' to the issue of notice to him under sub-section 2 of section 14, voluntarily and in good faith, made full disclosure of his wealth ......." 4. Strong reliance has been placed by Shri Bhattacharjee on the decision of the Allahabad High Court in Hasan Ahmad Khan vs. Commissioner of Wealth-Tax, 99 ITR 414. The facts of that case are almost identical with the case at hand. It was held there that if the assessee honestly though that he had fully disclosed his net wealth, although the disclosure made by him is ultimately found to be inaccurate, it would not be poss­ible to say that he did not act in good faith. The expression in good faith made full disclosure of his net wealth" finding place in the relevant part of section 18 (2A) merely means, said the Division Bench, that the assessee should have honestly described all his assets and liabilities which go to constitute his net wealth along with their estimated value. Once this has been done it would become possible for the Commissioner to cons­ider the assessee's application u/s. 18 (2A) for waiving the penalty imposable upon him. 5. The basic requirement being of "disclosure", of course full and in good faith, it is apparent that once the assessee lays open his assets and liabilities and makes an honest esti­mation of the same, the requirement of this part of law would be satisfied. 5. The basic requirement being of "disclosure", of course full and in good faith, it is apparent that once the assessee lays open his assets and liabilities and makes an honest esti­mation of the same, the requirement of this part of law would be satisfied. The word "disclosure" indicates that something is exposed, brought to light, uncovered, laid open or revealed, which was earlier kept hidden. There is no dispute in the present case that the assessee had fully disclosed the immova­ble property owned by him. The only hitch is regarding the estimation of the value of the property. Assessee's explana­tion is that though the half share of the property came to Rs. 72,750/-, he valued the same at Rs. 61,250/-, because the property being a joint family property, half of its share if sold in the market would not have fetched just the half of the total valuation. It is for the learned Commissioner to accept or not this explanation. What lies within my purview is to state that merely because the estimate of the assessee was not found acceptable, the assessee could not have been totally den­ied relief under section 18 (2A) of the Act inasmuch as it cannot be said that the same had resulted in failure to make full disclosure. It is pertinent to note that good faith of the assessee was not doubted. The main thrust of this require­ment seems to be on the disclosure of each parcel of physical assets owned by an assessee. Let it be said that view about estimation vary, and even if the assessee would have valued his share at Rs. 72,750/- in the present cases, it could have been well said (as it has been) by the learned Commissioner that he under estimated the same, as the valuation has to be according to the market trend, opinions about which are most likely to differ. If benefit contemplated by the section has to be denied on the score of under estimation, made even in good faith, it would render the provision a dead letter. It would have been a different matter if because of this full benefit of the section we would not have been made available to the assessee. But total denial of the relief on the ground which prevailed on the learned Commissioner has to be regarded as an apparent error of law. 6.

The impugned orders are, therefore, quashed and the matters are remanded to the learned Commissioner for disposal of the same in accordance with law. The petitions are allowed.
