Judgment :- R. JAYASIMHA BABU, J. The substantive question referred to us in this reference is as to whether rule 1D of the Wealth-tax Rules, 1957, is mandatory or directory. The Supreme Court in the case of Bharat Hari Singhania v. CWT while upholding the validity of rule 1D of the Wealth-tax Rules has held that: "Rule 1D has to be followed in valuing each and every case of unquoted equity shares of a company (other than an investment company or a managing agency company). It is not a matter of choice or option. The rule-making authority has prescribed only one method for valuing the unquoted equity shares. If be followed, there is no other method prescribed by the rules. Where there is a rule prescribing the manner in which a particular property has to be valued, the authorities u nder the Act have to follow it. They cannot devise their own ways and means for valuing the assets." The questions referred to us therefore have necessarily to be and are answered in favour of the Revenue and against the assessee. The assessee has not been served with notice in this reference. We have never theless proceeded to dispose of the reference having regard to the fact that the law on the question has been now declared authoritatively by the Supreme Court and the law so declared is binding on all persons and authorities in India including the assessee. However, we reserve liberty to the respondent in this reference to apply to us for the purpose of making any submission which though material for the purpose of disposing of this reference had not been brought to our notice by the Revenue. The matter is remitted to the Tribunal to determine the value of the unquoted equity shares in accordance with rule 1D of the Wealth-tax Rules.
