proviso includes overtime rates. The proviso gives the transferred
officer a guarantee of a minimum rate, inter alia, for overtime. The
relevant comparison is between the Federal and State rates of
remuneration for overtime. But it would not determine the issue
whether the plaintiff has been treated less favourably than the
proviso requires to make a comparison between the actual amount
of his Federal remuneration and a hypothetical amount of State
remuneration, or in other words, between his total receipts in the
Federal service and what he would have received if he had attended
for the performance of duty in the State service for the same total
number of hours as he attended for duty in the Federal service. In
the present case the question comes down to a comparison between
the rate prescribed under s. 6 (1) for overtime, that is, time beyond
the regular office hours prescribed under this sub-section, and the
overtime rate under the State award. As regards overtime, the
proviso does not require that the hours worked by a transferred
officer in the Commonwealth service be apportioned on the basis of
State law between usual office hours and overtime, and the State
overtime rate be applied to overtime ascertained in that way. I
think that the proviso requires that in respect of overtime determined
according to Federal law the overtime rate prescribed by Federal law
for any transferred officer in pursuance of s. 6 (1) should not fall
below the standard mentioned in the proviso. Regarding the matter
in that way, upon the facts of the present case, there has been no
departure from the proviso. So far as work done during the hours
mentioned in Questions 2 (a) and (c) is concerned, this would be
Commonwealth " overtime " because it was not done during usual
office hours fixed under Commonwealth law ; but so far as the hours
mentioned in Question 2 (6) are concerned, these were Common-
wealth "usual office hours." I think, therefore, that the answers
to Questions 2 (a), (6) and (c) should be Yes, No, Yes, respectively.
The answer to Question 3 should in my opinion be No.
