But par. (b), dealing with cases of injuries received before the
first amending Act of 1951, contained a difference of expression
which gives rise to the problem in the present case. The provision
it makes for a case which falls within its terms is that the amount:
of the average weekly earnings of the worker before the injury
shall be deemed to be increased as from the commencement of the
amending Act No. 20 of 1951 by the difference between the living
wage, the needs basic wage or the basic wage, as the case may be,
applicable at the time of the injury and the basic wage applicable
at such commencement; and it adds that after such commence-
ment the average weekly earnings shall be deemed to be increased
or reduced from time to time by the amounts by which and from
the dates from which the basic wage applicable at such commence-
ment is subsequently increased or reduced as the case may be. (The
expressions the living wage, the needs basic wage and the basic
wage, it may be mentioned, are defined ; broadly, they refer to
amounts so denominated at different periods for the purposes of
industrial awards). The problem in the present case arises from
the fact that the paragraph is expressed as applying " in the case
of an adult worker in receipt of compensation at the commence-
ment of the Workers' Compensation (Amendment) Act, 1951, or
who after such commencement receives compensation in respect
of an injury which occurred before such commencement He Allie
argument addressed to us on behalf of the appellant is that the two
cases described in the words quoted do not include the case of a
worker such as the respondent. True, he was injured before the
commencement of the amending Act, and at that date he was still
partially incapacitated for work as a result of the injury. But, it
is said, he is not within the first class described in the paragraph,
for he was not at that date "in receipt of compensation », even
though this expression should be construed as meaning actually
receiving or entitled to receive weekly payments under a current
award. Nor (the argument proceeds) is he within the second class,
even on a corresponding interpretation of the expression " receives
compensation", for he cannot bring himself within that class
