Counsel for the plaintiff relied upon the following passage relating to s. 216 of the Assessment Act in the judgment of this Court in Stapleton v. Federal Commissioner of Taxation [1] : "That section applies in any case where, whether intentionally or not, "a taxpayer escapes full taxation in his lifetime by reason of not having made full, complete and accurate returns" and for the purposes of considering the validity of this contention it may be assumed that this is such a case. It is, therefore, a case in which the respondent has the same powers and remedies against the trustees of the estate of the deceased in respect of the taxable income of the deceased as he would have had against the deceased if he were still living. By the relevant provisions of s. 216 (a) the respondent was, as we understand them, authorised for all purposes relating to the assessment and recovery of tax to regard the trustee or trustees of the deceased's estate as if they were the deceased himself. He might assess the trustees of the estate and proceed against them for the recovery of tax though he could not, of course, recover from them anything in excess of the value of the assets in their hands at the time of the assessment or coming to their hands thereafter (cf. Patterson v. Federal Commissioner of Taxation [2] ). In addition, the respondent, by virtue of s. 216 (d) is given a first charge "on all the taxpayer's estate in their hands". It was said in the course of argument that the liability of the trustees in such a case is an original and independent liability and, therefore, that it does not constitute a debt provable in the course of a bankruptcy administration but this view must be rejected. The section contemplates the imposition of a liability upon the trustees who represent the deceased taxpayer, the amount of the assessment is enforceable only to the extent of the trust estate in their hands and payment to this extent is secured by a charge on the estate. The liability is one which is imposed upon them in a representative capacity and is truly one which fastens on the estate itself. These considerations dispose entirely of the suggestion that an assessment validly made under s. 216 does not constitute a debt owing by the estate" [3] . But there is nothing in this passage which throws any light on the present question. It establishes of course that the debt for unpaid tax is a debt owing by the estate and charged upon the estate but it has nothing to say upon the question whether the debt can be recovered not from the trustees or out of the estate whilst it is still in their hands but from a beneficiary to whom the estate or part of the estate has been distributed in due course of administration. In my opinion this question should be answered in favour of the defendant. I venture to repeat, mutatis mutandis, what I said in Federal Commissioner of Taxation v. Official Receiver [1] to the effect that the Assessment Act is an Act which provides a complete and exhaustive code of the rights and obligations of the commissioner and other officers of his department to members of the general public who are subject to its provisions and of those members of the general public to his department. In my opinion the whole scheme of the Act, to be gathered from its general structure and its specific provisions, is to confine the liability to pay income tax to persons who can be assessed under the Act and upon whom is conferred the right of appeal against the assessment either by way of reference to a board of review or by appeal to the Court at their option. Reference to some of the more important provisions of the Act make this apparent. Section 6 provides that in the Act, unless the contrary intention appears - taxpayer "means a person deriving income". Part IV which is headed "Returns and Assessments" contains ss. 161 to 177 inclusive. Section 166 provides that "From the returns, and from any other information in his possession, or from any one or more of these sources, the Commissioner shall make an assessment of the amount of the taxable income of any taxpayer, and of the tax payable thereon". Section 167 provides: - "If - (a) any person makes default in furnishing a return; or (b) the Commissioner is not satisfied with the return furnished by any person; or (c) the Commissioner has reason to believe that any person who has not furnished a return has derived taxable income, the Commissioner may make an assessment of the amount upon which in his judgment income tax ought to be levied, and that amount shall be the taxable income of that person for the purpose of the last preceding section". Section 169 provides: - "Where under this Act any person is liable to pay tax, the Commissioner may make an assessment of the amount of such tax". Section 174 provides: "As soon as conveniently may be after any assessment is made, the Commissioner shall serve notice thereof in writing by post or otherwise upon the person liable to pay the tax". Section 177 (1) provides: "The production of a notice of assessment, or of a document under the hand of the Commissioner, Second Commissioner, or a Deputy Commissioner, purporting to be a copy of a notice of assessment, shall be conclusive evidence of the due making of the assessment and (except in proceedings on appeal against the assessment) that the amount and all the particulars of the assessment are correct". All these provisions, it will be seen, operate and operate only between the commissioner and some particular member of the public. Section 169 confers on the commissioner a power to make an assessment additional to the power to make an assessment conferred upon him by s. 166 but it is only a power to make an assessment "where any person is liable to pay tax".
