62B Use of extrinsic material in interpreting Act
(1) In interpreting a provision of an Act, if material not forming part of
the Act is capable of assisting in ascertaining the meaning of the
provision, the material may be considered:
(a) to confirm that the meaning of the provision is the ordinary
meaning conveyed by the text of the provision taking into
account its context in the Act and the purpose or object
underlying the Act; or
(b) to determine the meaning of the provision when:
(i) the provision is ambiguous or obscure; or
(ii) the ordinary meaning conveyed by the text of the
provision taking into account its context in the Act and
the purpose or object underlying the Act leads to a result
that is manifestly absurd or is unreasonable.
(2) Without limiting subsection (1), the material that may be considered
in interpreting a provision of an Act includes the following:
(a) all matters not forming part of the Act that are set out in the
document containing the text of the Act as printed by the
Government Printer;
(b) any relevant report of a Royal Commission, Law Reform
Commission, committee of inquiry or other similar body that
was laid before the Legislative Assembly before the time when
the provision was enacted;
(c) any relevant report of a committee of the Legislative Assembly
that was made to the Legislative Assembly before the time
when the provision was enacted;
(d) any treaty or other international agreement that is referred to
in the Act;

(e) any explanatory memorandum relating to the Bill containing
the provision, or any other relevant document, that was laid
before, or furnished to the members of the Legislative
Assembly by a Minister or other Member before the time when
the provision was enacted;
(f) any explanatory speech or statement given by a Minister or
other Member to the Legislative Assembly on introducing the
Bill;
(g) any document (whether or not a document to which a
preceding paragraph applies) that is declared by the Act to be
a relevant document for the purposes of this section;
(h) any relevant material in any official record of debates in the
Legislative Assembly.
