22 Division 6 of Pt 5.6 of the Law was headed "Proof and ranking of claims". Section 553 in that Division "Debts or claims that are provable in winding up" provided:
"(1) Subject to this Division, in every winding up, all debts payable by, and all claims against, the company (present or future, certain or contingent, ascertained or sounding only in damages), being debts or claims the circumstances giving rise to which occurred before the relevant date, are admissible to proof against the company.".
23 Section 556(1) in Division 6 of Part 5.6 of the Law provided that in the winding up of a company certain "debts and claims must be paid in priority to all other unsecured debts and claims". There followed fourteen lettered paragraphs, the first ten of which consisted of various expenses, costs and debts incurred in the course of winding up, official management or by a member of a committee of inspection. The last four paragraphs of subs(1) were:
"(e) subject to subsection (1A) [which limited the amount paid] - 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) [which limited the amount paid] - 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) [which excluded any amount attributable to non-priority days] - next, retrenchment payments payable to employees of the company."
Only paras (e) wages and superannuation contributions payable by the company in respect of services rendered to it by employees "before the relevant date", (g) amounts due on or before the relevant date to employees in respect of leave of absence under an industrial instrument, and (h) "retrenchment payments payable to employees of the company", were referred to in s433(3)(c). Paragraph (f), which was not referred to in s433(3)(c), gave priority to amounts due in respect of injury compensation, the liability for which arose before the relevant date. Subsection (1C) aside, para (h) set no temporal condition or limitation.
