But we heard considerable argument as to the meaning and effect of certain provisions of the Bankruptcy Act 1924-1950 and in particular of the extent to which the personal earnings of a bankrupt are after-acquired property which becomes divisible amongst his creditors under s. 91 (i) of the Bankruptcy Act. All property of a bankrupt which he acquires or which devolves upon him before his discharge does not necessarily become divisible among his creditors. Section 98 of the Bankruptcy Act validates all transactions by a bankrupt with any person dealing with him bona fide and for value, in respect of property, whether real or personal, acquired by the bankrupt after the sequestration, if completed before any intervention by the trustee. In addition to this general provision relating to intervention by the trustee there is also the very specific provision contained in s. 101. This section provides that subject to the Act, where a bankrupt is in receipt of pay, pension, salary, emoluments, profits, wages, earnings, or income, the trustee shall receive for distribution amongst the creditors so much thereof as the court, on the application of the trustee, directs. His Honour, having formed the opinion that the obligation of the commissioner to make a refund to the taxpayer was a chose in action deemed to be assigned to the official receiver, did not think it strictly necessary to refer to s. 101 but, "in deference to counsel", he made a brief reference to it. He said: "The after-acquired property of a bankrupt becomes vested in his trustee. See In re Pascoe [1] . To this statement of the law there are some qualifications, and one of these qualifications is contained in s. 101. Whether it is a matter of implication or a matter of assumption moneys of the various descriptions mentioned in s. 101 which are being received by a bankrupt and will in the ordinary course of things continue to be received by him can be retained by him unless the court orders that such moneys or a portion thereof should be received by the trustee for the benefit of the bankrupt's creditors. Section 101 is, I consider, an extension of the long established principle of the bankruptcy law that a bankrupt is entitled to retain out of the fruits of his labours sufficient for the purpose of maintaining himself and his family." This statement can broadly be accepted. The personal earnings of a bankrupt, including his earnings by way of salary or wages, are, on the literal reading of s. 91 (i), after-acquired property of the bankrupt. As such they would vest in the official receiver, as and when the bankrupt received them, and, subject to s. 98, would be part of the property of the bankrupt divisible amongst his creditors. But it has invariably been held that the vesting provisions of Bankruptcy Acts must not be read literally so as to vest the whole of the personal earnings of the bankrupt in his official assignee because to do so would mean that the assignee might, in the words of Lord Mansfield in Chippendale v. Tomlinson [1] : "let the insolvent out to hire, and contract himself for his personal labour": Williams v. Chambers [2] . In In re Roberts [3] , Lindley M.R., delivering the judgment of the Court of Appeal, said that the language of s. 44 (i) of the Bankruptcy Act 1883 Imp. (which corresponds to s. 91 (i) of our Act), "clear and express as it is, must not, be taken so literally as to deprive the bankrupt of those fruits of his personal exertions which are necessary to enable him to live. But, on the other hand, the necessity is the limit of the exception" [4] . His Lordship then referred to certain cases and continued: "Those cases are no authority for the proposition that property of a bankrupt acquired by his personal exertions since his bankruptcy and not wanted for his present support does not belong to his trustee. No such doctrine can be maintained in face of s. 44. After bankruptcy, and before his discharge, whatever property a bankrupt acquires belongs to his trustee, save only what is necessary for his support" [5] . These passages would at first sight suggest that the earnings of a bankrupt would automatically vest in his trustee except so much thereof as was required for the present support of himself and his family without the trustee obtaining an order of the court directing payment of the earnings or part thereof to him during the bankruptcy. But in the later case in the Court of Appeal of Affleck v. Hammond [6] , this judgment of Lindley M.R. was discussed and it was pointed out by Buckley L.J. (as Lord Wrenbury then was) that it was one of the facts in In re Roberts [1] "that the property was not wanted for the bankrupt's support or maintenance; the trustee would therefore be entitled to the whole of it" [2] . In Affleck v. Hammond [3] it was held that a bankrupt who earns salary or wages is entitled to have them paid to him and that he can, if necessary, sue to recover the whole of his personal earnings because, to the extent that they are required for his maintenance, the earnings do not vest in the trustee. Buckley L.J. said: "the trustee can only get the money upon an application to the court" [2] . In Nette v. Howarth [4] , Dixon J. (as he then was) said: "In the receipts enumerated in s. 101 the words "pay", "salary" and "wages" refer to remuneration earned by present service. "Pension" refers predominantly to payments which follow service. The time has passed when the idiomatic use of the word extended to non-recurring payments. But it may perhaps include in this section a succession of payments which are not the consequence of past service or the like. "Emolument" too is a word which has ceased to bear its original meaning of mere gain, profit, or advantage. It too relates to revenue, whether casual or constant, arising from an office, station, or situation. "Profits", "earnings" and "income" are wide words. They cover the fruits of labour and much more besides. For example, "income" in the analogous s. 51 (2) of the English Bankruptcy Act 1914 includes maintenance payable under an order in divorce (In re Landau; Ex parte Trustee [5] ). Decisions interpreting expressions reproduced in the Australian section which occur in s. 51 and corresponding previous British enactments will be found in that case (In re Landau [5] ) and in Hollinshead v. Hazleton [6] . But the English and Australian provisions alike appear to be directed at revenue receipts. Indeed, they are reminiscent of the rule long established in bankruptcy, that the personal earnings of a bankrupt do not pass to his trustee except to the extent that they are not required for the support of himself and his family" [7] . The law is stated in the same way in In re Walter; Slocock v. Official Receiver [8] where Tomlin J. (as Lord Tomlin then was) said: "the section (that is s. 38 of the Bankruptcy Act 1914) does not deprive the bankrupt of those fruits of his personal exertions which are necessary to enable him to live; in other words it is only the surplus over and above that which vests in the trustee" [9] . In In re Shine; Ex parte Shine [1] , Bowen L.J. said: "As the Master of the Rolls has already said, the original contract was for personal services, and the creditors are not entitled to the benefit of it by the law of bankruptcy; and, until this sub-section was put in force against him, by diverting to the use and advantage of his creditors that which was primâ facie up to that moment his own, he had a perfect right, although he was a bankrupt, to make any bargain he pleased with any person as to the remuneration which he was to receive for his personal services" [2] . These and other cases cited to us establish that the question whether any part and if so what part of the personal earnings of a bankrupt vests in the official receiver as after-acquired property is really academic. If the official receiver claims any part of these earnings, he must apply to the Bankruptcy Court for an order. He must intervene in this specific manner. In the absence of such an order the bankrupt is free to dispose of the whole of these earnings. The English cases were decided in relation to sections in succeeding English Bankruptcy Acts which provided that, so far as material, where a bankrupt is in the receipt of a salary or income the court upon the application of the trustee shall from time to time make such order as it thinks just for the payment of such salary or income, or of any part thereof, to the trustee during the bankruptcy. The sections in question are - in the Bankruptcy Act 1869 Imp., s. 90, the Bankruptcy Act 1883 Imp., s. 53 (2), the Bankruptcy Act 1914 Imp., s. 51 (2). Section 101 of the Bankruptcy Act Cth. includes more classes of property than the English Acts and it is also somewhat differently expressed. It provides that where a bankrupt is in receipt of pay etc. the trustee shall receive so much thereof as the court, on the application of the trustee, directs. It therefore provides in express terms that an order of the court is necessary before any part of such pay etc. can be recovered by the trustee and it is implicit in the section that in the absence of such an order none of the pay etc. vests in the trustee under s. 91 (i) of the Act. It is the order that effectively vests the pay or any part thereof in the trustee. It thereby becomes part of the property of the bankrupt divisible amongst his creditors. The order can only apply to pay etc. of which the bankrupt is "in receipt" and this means in actual receipt (per Bowen L.J. in In re Shine; Ex parte Shine [3] ). His Honour, in his reasons, said that it would be strange indeed that where a taxpayer has paid to the commissioner a sum which is more than sufficient to discharge his liability for tax, the excess amount which the taxpayer is entitled to receive back from the commissioner can be regarded as earnings or income of the taxpayer within the meaning of s. 101. But what is there strange about that? The instalments on account of tax that were deducted under the provisions of Pt. VI, Div. 2 of the Assessment Act were made from the salary or wages of the employee. Apart from these provisions the employer would have been bound to pay the bankrupt his salary or wages in full. It was part of these earnings that were appropriated for that purpose. But it was only a provisional appropriation. The commissioner is obliged to repay any sum found to be in excess of the required amount. The commissioner is obliged to restore the excess to the taxpayer and if the over collections were made out of salary or wages the restoration must be a refund of part of these salary or wages. It is a refund of part of the earnings of the bankrupt and money which he is entitled to retain in the absence of an order of the court under s. 101 of the Act. When he receives the refund and not before he will become for the first time in actual receipt of this part of his earnings. The official receiver may be able to obtain an order of the Bankruptcy Court under s. 101 of the Bankruptcy Act against the bankrupt for payment by the bankrupt of this sum or part thereof to him but it is not an order with which the deputy commissioner is concerned. It is the duty of the latter to pay the whole of the sum in question to the bankrupt and to make no disclosures about it to the official receiver. How otherwise could he comply with s. 16 of the Assessment Act.
