an employer has, since the second day of March, 1942, employed, is employing, or proposes to employ, females on work" " which is defined by the regulation. Accordingly, reg. 6 in the schedule (as re-introduced by statutory rule No. 75) applies to cases of employ- ment before the introduction of statutory rule No. 548 (on 23rd December 1942) to which No. 548 did not apply. The regulation contained in the schedule includes all the cases to which No. 548 applied, and SO far is identical with No. 548 but it adds another case, namely, the case mentioned of certain past employment (between 2nd March 1942 and 22nd December 1942), to the cases included in No. 548. This is the difference between the two regulations SO far as element 1 is concerned. No. 548 is re-enacted with a small addition.
(2) The next element in the regulations relates to what I have called the defined work. In reg. 6 in statutory rule No. 548, the work is defined as follows: Work-
"(a) which is usually performed by males
(b) which was, during the period from the third day of September, 1939, to the date of the employment of, or proposal to employ, females, performed by males in the establishment of the employer; or
(c) which was not, during that period, performed in Australia by any person"
In reg. 6 in the schedule the work is defined in the following manner (I have added distinguishing letters for the sake of clearness)
(a) work which is usually performed by males; (b) work which was, prior to that employment of females (that is, employment by the particular employer concerned), or is, per- formed by males in the establishment of that employer
(c) work which, prior to that employment, or proposed employ- ment of females, was not being performed in Australia by any person.
The definition of work in (a) is the same in each case. In (b) and (c) it is the same except in relation to the period during which the work has been performed. In No. 548 the relevant period is "from the third day of September, 1939, to the date of the employment of, or proposal to employ, females." In the schedule the period in the case of (b) is described by the words "prior to that employment of females," and in the case of (c) by the words "prior to that employment or proposed employment of females."
The effect, therefore, of the re-introduction of the provision in the schedule is to repeat in respect of this part of the regulation all the provisions of statutory rule No. 548 but to include also in respect of the definition of "work" contained in (b) and (c) the period before 3rd September, as well as a period after that day. Thus the
