into operation on the day on which it is delivered or on such later date as
the Commission determines and declares when delivering the award.
(2) Subject to
subsection (3), the provisions of an award have effect on such day or
days as is or are, respectively, specified in the award.
(3) The Commission
may, by its award, give retrospective effect to the whole or any part of the
award —
(a) if
and to the extent that the parties to the award so agree; or
(b) if,
in the opinion of the Commission, there are special circumstances which make
it fair and right so to do,
but in a case to which
paragraph (b) applies, not beyond the date upon which the application
leading to the making of the award was lodged in the Commission.
(4) For the purpose of
subsection (3), an award or a provision of it has retrospective effect if
and only if it has effect from a date earlier than the day on which the award
is delivered.
