27 On this footing, the conclusion is that the claims of the persons the subject of the present application had their "origin" or "genesis" in circumstances occurring before the relevant date. In consequence, they are provable debts within s 553(1).
28 I turn now to the question whether the claims of relevant customers come within any of the priority categories in s 556(1):
"Subject to this Division, in the winding up of a company the following debts and claims must be paid in priority to all other unsecured debts and claims:
(a) first, expenses (except deferred expenses) properly incurred by a relevant authority in preserving, realising or getting in property of the company, or in carrying on the company's business;
(b) if the Court ordered the winding up - next, the costs in respect of the application for the order (including the applicant's taxed costs payable under section 466);
(c) next, the debts for which paragraph 443D(a) entitles an administrator of the company to be indemnified (even if the administration ended before the relevant date), except expenses covered by paragraph (a) of this subsection and deferred expenses;
(d) if the winding up began within 2 months after the end of a period of official management of the company - next, debts of the company properly incurred by an official manager in carrying on the company's business during the period of official management, except expenses covered by paragraph (a) of this subsection and deferred expenses;
(da) if the Court ordered the winding up - next, costs and expenses that are payable under subsection 475(8) out of the company's property;
(db) next, costs that form part of the expenses of the winding up because of subsection 539(6);
(dc) if the winding up began within 2 months after the end of a period of official management of the company - next, the remuneration, in respect of the period of official management, of any auditor appointed in accordance with Part 2M.4;
(dd) next, any other expenses (except deferred expenses) properly incurred by a relevant authority;
(de) next, the deferred expenses;
(df) if a committee of inspection has been appointed for the purposes of the winding up - next, expenses incurred by a person as a member of the committee;
(e) subject to subsection (1A) - next, wages and superannuation contributions payable by the company in respect of services rendered to the company by employees before the relevant date;
(f) next, amounts due in respect of injury compensation, being compensation the liability for which arose before the relevant date;
(g) subject to subsection (1B) - next, all amounts due:
(i) on or before the relevant date; and
(ii) because of an industrial instrument; and
(iii) to, or in respect of, employees of the company; and
(iv) in respect of leave of absence;
(h) subject to subsection (1C) - next, retrenchment payments payable to employees of the company."
29 The only paragraphs of s 556(1) considered by the liquidators to be potentially relevant are paragraphs (a), (dd) and (c). Paragraphs (a) and (dd) are concerned with "expenses … properly incurred". I am of the opinion that the emergence of a liability to refund, in the circumstances under discussion, did not entail any "incurring" by One.Tel and that it cannot be said that the liability to refund was "properly incurred". The reasons are those stated by me in McDonald v Commissioner of Taxation (above). In short, neither One.Tel nor its liquidators did nothing to precipitate the liability to refund. I should also say that I am not satisfied that the liability to refund is properly regarded as an "expense".
30 Section 556(1)(c) affords priority to:
"next, the debts for which paragraph 443D(a) entitles an administrator of the company to be indemnified (even if the administration ended before the relevant date), except expenses covered by paragraph (a) of this subsection and deferred expenses;"
31 Section 443D is in these terms:
"The administrator of a company under administration is entitled to be indemnified out of the company's property for:
(a) debts for which the administrator is liable under Subdivision A or a remittance provision as defined in subsection 443BA(3); and
(b) his or her remuneration as fixed under section 449E.
32 By referring back to "Subdivision A", s 443D(a) operates upon and in relation to a number of classes of debts for which a Part 5.3A administrator is made liable by provisions in Subdivision A of Division 9 of Part 5.3A. Apart from debts within those classes, an administrator is not liable for the company's debts: s 443C. The only class of debts for which an administrator is made liable and which is of any potential relevance here is that in s 443A:
"(1) The administrator of a company under administration is liable for debts he or she incurs, in the performance or exercise, or purported performance or exercise, of any of his or her functions and powers as administrator, for:
(a) services rendered; or
(b) goods bought; or
(c) property hired, leased, used or occupied.
