37 Any matter or thing relating to electricity prescribed by the Regulations. Schedule 2—Miscellaneous provisions relating to interpretation (section 3) 1—Displacement of Schedule by contrary intention (1) The application of this Schedule to this Law, the Regulations or other statutory instrument (other than the National Electricity Rules) may be displaced, wholly or partly, by a contrary intention appearing in this Law or the Regulations or that statutory instrument. (2) The application of this Schedule to the National Electricity Rules (other than clauses 7, 12, 15, 17, 19, 23 to 26 and 31 to 34, 39, 42 and 43 of this Schedule) may be displaced, wholly or partly, by a contrary intention appearing in the National Electricity Rules. Part 2—General 2—Law to be construed not to exceed legislative power of Legislature (1) This Law is to be construed as operating to the full extent of, but so as not to exceed, the legislative power of the Legislature of this jurisdiction. (2) If a provision of this Law, or the application of a provision of this Law to a person, subject matter or circumstance, would, but for this clause, be construed as being in excess of the legislative power of the Legislature of this jurisdiction— (b) the remainder of this Law, and the application of the provision to other persons, subject matters or circumstances, is not affected. (3) Without limiting subclause (2), this Law is not to be construed as imposing any duty on the Tribunal or AER to perform a function or exercise a power if the imposition of the duty would be in excess of the legislative power of the Legislature of this jurisdiction. The term "function" is defined in clause 10 to include "duty". (4) In particular, if a provision of this Law appears to impose a duty on a Commonwealth officer or body to perform a function or exercise a power, the duty is taken to be imposed by the provision to the extent to which imposing the duty— (a) is within the legislative powers of this jurisdiction; and (b) is consistent with the constitutional doctrines under the Constitution of the Commonwealth restricting the duties that may be imposed on a Commonwealth officer or body. (4a) To avoid doubt, a provision of this Law does not impose the duty on the Commonwealth officer or body to the extent to which imposing the duty would— (a) contravene any constitutional doctrine under the Constitution of the Commonwealth restricting the duties that may be imposed on a Commonwealth officer or body; or (b) otherwise exceed the legislative powers of this jurisdiction. (4b) If imposing on the Commonwealth officer or body the duty to do that thing would— (a) contravene any constitutional doctrine restricting the duties that may be imposed on a Commonwealth officer or body; or (b) otherwise exceed the legislative powers of both the State and the Commonwealth, the provision of this Law is taken instead to confer on the Commonwealth officer or body a power to do that thing at the discretion of the Commonwealth officer or body (as the case may require). (5) This clause does not limit the effect that a provision of this Law would validly have apart from this clause. 2A—Changes of drafting practice not to affect meaning Differences of language between provisions of this Law or the Rules may be explicable by reference to changes of legislative drafting practice and do not necessarily imply a difference of meaning. 3—Every section to be substantive enactment Every section of this Law has effect as a substantive enactment without introductory words. 4—Material that is, and is not, part of Law (1) The heading to a Chapter, Part, Division or Subdivision into which this Law is divided is part of this Law. (2) A Schedule to this Law is part of this Law. (3) A heading to a section or subsection of this Law does not form part of this Law. (4) A note at the foot of a provision of this Law does not form part of this Law. (5) An example (being an example at the foot of a provision of this Law under the heading "Example" or "Examples") does not form part of this Law. 5—References to particular Acts and to enactments (a) an Act of this jurisdiction may be cited— (ii) in another way sufficient in an Act of this jurisdiction for the citation of such an Act; and (b) a Commonwealth Act may be cited— (ii) in another way sufficient in a Commonwealth Act for the citation of such an Act, together with a reference to the Commonwealth; and (c) an Act of another jurisdiction may be cited— (ii) in another way sufficient in an Act of the jurisdiction for the citation of such an Act, together with a reference to the jurisdiction. 6—References taken to be included in Act or Law citation etc (1) A reference in this Law to an Act includes a reference to— (a) the Act as originally enacted, and as amended from time to time since its original enactment; and (b) if the Act has been repealed and re enacted (with or without modification) since the enactment of the reference, the Act as re enacted, and as amended from time to time since its re enactment.

(2) Subclause (1) applies whether or not the purpose is expressly stated in this Law. 8—Use of extrinsic material in interpretation Law extrinsic material means relevant material not forming part of this Law, including, for example— (a) material that is set out in the document containing the text of this Law as printed by authority of the Government Printer of South Australia; and (b) a relevant report of a committee of the Legislative Council or House of Assembly of South Australia that was made to the Legislative Council or House of Assembly of South Australia before the provision was enacted; and (c) an explanatory note or memorandum relating to the Bill that contained the provision, or any relevant document, that was laid before, or given to the members of, the Legislative Council or House of Assembly of South Australia by the member bringing in the Bill before the provision was enacted; and (d) the speech made to the Legislative Council or House of Assembly of South Australia by the member in moving a motion that the Bill be read a second time; and (e) material in the Votes and Proceedings of the Legislative Council or House of Assembly of South Australia or in any official record of debates in the Legislative Council or House of Assembly of South Australia; and (f) a document that is declared by the Regulations to be a relevant document for the purposes of this clause; ordinary meaning means the ordinary meaning conveyed by a provision having regard to its context in this Law and to the purpose of this Law; Rule extrinsic material means— (a) a draft Rule determination; or (b) a final Rule determination; or (c) any document (however described)— (i) relied on by the AEMC in making a draft Rule determination or final Rule determination; or (ii) adopted by the AEMC in making a draft Rule determination or final Rule determination.

(2a) Subject to subclause (3), in the interpretation of a provision of the Rules, consideration may be given to Law extrinsic material or Rules extrinsic material capable of assisting in the interpretation— (a) if the provision is ambiguous or obscure, to provide an interpretation of it; or (b) if the ordinary meaning of the provision leads to a result that is manifestly absurd or is unreasonable, to provide an interpretation that avoids such a result; or (c) in any other case, to confirm the interpretation conveyed by the ordinary meaning of the provision. (3) In determining whether consideration should be given to Law extrinsic material or Rule extrinsic material, and in determining the weight to be given to Law extrinsic material or Rule extrinsic material, regard is to be had to— (a) the desirability of a provision being interpreted as having its ordinary meaning; and (b) the undesirability of prolonging proceedings without compensating advantage; and (c) other relevant matters. 9—Compliance with forms (1) If a form is prescribed or approved by or for the purpose of this Law, strict compliance with the form is not necessary and substantial compliance is sufficient.
