Policy

Section 42 of the Interpretation Act 1984 requires certain instruments of subsidiary legislation [1] to be tabled in both Houses of Parliament within 6 sitting days after their publication in the Government Gazette or on the Western Australian Legislation website (WAL website). Section 42 also makes such instruments subject to parliamentary disallowance.

There are also other Acts (empowering Acts) that require instruments of subsidiary legislation (and quasi-legislation) made under those Acts to be tabled in both Houses of Parliament. These empowering Acts may make the instruments subject to parliamentary disallowance, either by:

  • applying section 42 of the Interpretation Act 1984 to the instrument [2]
    or
  • prescribing their own disallowance procedure for the instrument. [3]

The Joint Standing Committee on Delegated Legislation (JSCDL) holds a standing referral to scrutinise all instruments of subsidiary legislation (or quasi-legislation) on behalf of the Parliament of Western Australia. Instruments are referred to the JSCDL on their publication, usually either in the Government Gazette or on the WAL website. ‘Instrument’ means:

  • ‘subsidiary legislation’ as it is defined in section 5 of the Interpretation Act 1984 [4]
  • an instrument, not being subsidiary legislation, that is made subject to parliamentary disallowance under a written law. [5]

The JSCDL focuses its scrutiny on instruments that are made subject to parliamentary disallowance, either under section 42 of the Interpretation Act 1984 or an empowering Act.

To enable the JSCDL to carry out its functions, the agency responsible for administering an instrument that is subject to parliamentary disallowance must provide the following documents within 10 business days after the publication date:

  1. One electronic copy of the instrument as published in the Government Gazette or on the WAL website;
  2. One electronic copy of an Explanatory Memorandum (EM), prepared in accordance with this Circular (see Appendix 1), signed by the Chief Executive Officer (CEO) of the agency and initialled or signed by the responsible Minister; [6]
  3. One electronic copy of a completed Statutory Procedures Checklist in Appendix 2 format for a region planning scheme or an amendment to it;
  4. For amending instruments, if the principal instrument is not published on the WAL website, an electronic copy of the principal instrument with all amendments consolidated up to the date immediately before the most recent amendments take effect;
  5. Where the Parliamentary Counsel’s Office (PCO) has produced a copy of the principal instrument marked with the amendments made by the instrument under scrutiny, a link to the ‘document compare’ on the WAL website.

For instruments where notice of a disallowance motion must be given within fewer than the 14 sitting days provided for in section 42 of the Interpretation Act 1984, the agency must provide this documentation within 5 business days after publication in the Government Gazette or on the WAL website.

Further information regarding the required content of EMs is in Appendix 1.

The documents must be emailed in PDF/A format to delleg@parliament.wa.gov.au. The subject line of the email must clearly identify the instrument under scrutiny.

Background

The Parliament of Western Australia established the JSCDL to assist with the scrutiny of instruments of subsidiary legislation (and quasi-legislation) made subject to parliamentary disallowance under either section 42 of the Interpretation Act 1984 or the instrument’s empowering Act.

The JSCDL cannot properly fulfil its scrutiny role without timely provision of explanatory material for each instrument referred to it upon publication. Agencies must provide the required material in a timely manner. These requirements are additional to the statutory requirement to table certain instruments in both Houses of the WA Parliament within (usually) 6 sitting days after publication in the Government Gazette or on the WAL website.
