"I turn now to an examination of the section in itself and
in its relationship with other parts of the Act. The
section operates on a factual situation in which the
employer is making weekly payments to the workman pursuant
to s 51. He may be doing this in voluntary discharge of his
obligations, or because an application that s 53(1) does not
apply has not been made in time or has been refused, or
pursuant to an order of the Court made on an application
under s 39. The section prohibits discontinuance or
diminution of the payments except under specified
conditions, and makes discontinuance or diminution otherwise
than in accordance with the section an offence carrying a
fine. The entitlement to discontinuance or diminish under
the specified conditions is spoken of in sub-s (2) as a
'right'. If the workman disputes that 'right' he may apply
to the Court. If the application is dismissed the payments
may be discontinued or diminished. The Court may 'make such
order as to the continuance of the weekly payments as it
thinks fit'. The application must be dealt with in the
summary list. The conditions which give rise to the 'right'
to discontinue or diminish are two in number. The first is
the return of the workman to work. The second is
certification by a medical practitioner that the workman has
wholly or partially recovered or that the incapacity is no
longer a result of the injury and service on the workman of
a copy of the certificate including the grounds for the
opinion, together with twenty-one days notice of intention
to diminish or discontinue the payments. On a strictly
literal reading of the section as it stood prior to the 1979
amendment it could be argued that the second condition is
not fulfilled if the workman makes application to the Court
within the twenty-one day period. I think, however, that
such a reading would carry literalness too far. I do not
think that failure to make application is an ingredient of
the second condition giving rise to the 'right'. The
intention is simply to ensure that the payments are not
discontinued or diminished in fact until the Court has
adjudicated upon the workman's challenge to the right.
Although it is not permissible to use the 1979 amendment as
an aid to the construction of the section as it stood prior
to the amendment, it is interesting to note that this
meaning is made clear by that amendment. The reference to
the application by the workman is removed from sub-s (1)
which specifies the conditions which found the 'right' and
appears in a new sub-s (2a), which provides directly that
where the workman takes out the application the payments
shall not be discontinued or diminished pending
determination of the application. Section 52 immediately
follows the section which fixes the amount of compensation
as a weekly payment during incapacity. It immediately
precedes the section which obliges the employer to commence
weekly payments upon receipt of evidence of the workman's
compensable incapacity unless the Court considers that a
genuine dispute as to liability exists. The section is by
its terms limited in its scope to the discontinuance or
diminution of payments on grounds of recovery. Its
procedures cannot be used to discontinue payments on other
grounds. Issues such as whether the recipient of the
payments was a workman, or whether he suffered an injury, or
whether the injury occurred in the course of or arising out
of the employment cannot be resolved under s 52. Issues
which could be raised in s 53 proceedings cannot be raised
in proceedings under s 52.
I cannot see any warrant in the section, in its relationship
with other parts of the Act, or in legal principle, for the
view which had apparently taken root in the Industrial Court
that the question in an application under the section is
whether it is inappropriate that payments should be
discontinued or diminished and that if the evidence as to
incapacity is finely poised it is inappropriate. What must
be established by the workman on such an application is not
that it is inappropriate that payments be discontinued or
diminished because the evidence is at least finely poised,
but whether the conditions necessary to found the 'right' of
the employer to discontinue or diminish exist. It is
necessary to consider what those conditions are.
As the Full Industrial Court saw it, the section, in
addition to prohibiting under penalty arbitrary
discontinuance or diminution of payments, provides the
machinery for determining finally the issue whether
incapacity continues and in consequence whether the
workman's right to weekly payments under s 51 continues. In
my opinion, this construction faces some formidable
difficulties. The foremost of these difficulties is that no
such indication is to be found in the words of the section.
The full Industrial Court considered that the question for
the Court is 'whether the workman had recovered either
wholly or partially from the injury or whether the
incapacity is no longer a result of it depending upon the
tenor of the relevant certificate of the medical
practitioner'. No such question can be gathered from the
language of the section. Sub-section (1) prescribes the
conditions which give rise to the right to discontinue or
diminish payments and the relevant condition relates to
notification and service of the certificate and notice. The
question for the Court relates to the existence of that
right. A further difficulty is that the section is not apt
to deal with the final resolution of the right to
discontinue payments. This right may depend upon issues as
to liability for compensation which do not come within the
scope of this section at all. Moreover the summary
procedure prescribed by the section cannot have been
intended for the final determination of contentious issues
as to the continued existence of work caused incapacity,
which are always of the utmost importance and sometimes of
considerable complexity. The provision that a s 52
application must be dealt with in the summary list and
cannot be removed from it is a strong indication against the
Full Industrial Court's construction."
