Changes to standing orders 23 and 25(2)(a)

On 27 November 2019, the Senate agreed to General Business Notice of Motion No. 84, standing in the name of the Chair of the Standing Committee on Regulations and Ordinances, to amend Senate standing orders 23 and 25(2)(a). The amendments accord with the recommendations of the bipartisan report of the committee's 2019 inquiry into parliamentary scrutiny of delegated legislation. In summary, they:

• modernise language and procedures;
• clarify the standing orders to reflect existing committee practice; and
• promote consistency with other Senate standing committees and scrutiny committees in other Westminster jurisdictions.

The amendments took effect on 4 December 2019. Further information about the amendments is available in this explanatory note.
