In my opinion this analysis of the cases mistakes the individual application or illustration for the principle itself. Whatever the position may be at the time of the issuing of a notice of assessment and whether or not it is correct to say, as Williams J. said in H. R. Lancey Shipping Co. Pty. Ltd. v. Federal Commissioner of Taxation [6] , that the Commissioner is under no obligation to furnish an "alteration sheet" indicating the adjustments which he has made to the taxable income as returned whether by way of addition of income or denial or allowable deductions, when an appeal comes before this Court or a Supreme Court from the Commissioner's disallowance of an objection, the position is quite different. Under ss. 187 and 196A such appeals go to the Supreme Courts of the States, and until regulations are made, are conducted under the High Court Rules which provide by O. 65, r. 2 that, subject to that order, the provisions of other orders also apply to taxation "appeals", which are of course in the original jurisdiction. It has not been the practice in this Court to require pleadings in taxation appeals, though it may well be that the rules are wide enough to enable this to be done. (See the definitions of plaintiff, defendant and proceeding in O. 1, r. 5 and the terms of O. 20.) In the absence of pleadings, the provisions of O. 20, r. 6 may not be directly applicable but in my opinion this Court and the Supreme Courts of the States hearing taxation appeals have inherent jurisdiction to require parties to give particulars if it appears just to do so. The fact that a proceeding may go forward without pleadings does not deprive the Court of such control as is necessary to ensure that the issues are defined and that each party is provided with the necessary information as to the case which he has to meet. The basis of the decision in Philliponi v. Leithead [7] applies equally in the High Court.
