The status of this republication appears on the bottom of each page.
Editorial changes
The Legislation Act 2001, part 11.3 authorises the Parliamentary Counsel to make editorial amendments and other changes of a formal nature when preparing a law for republication.  Editorial changes do not change the effect of the law, but have effect as if they had been made by an Act commencing on the republication date (see Legislation Act 2001, s 115 and s 117).  The changes are made if the Parliamentary Counsel considers they are desirable to bring the law into line, or more closely into line, with current legislative drafting practice.

3	Legislation history
This regulation was originally called the Boilers and Pressure Vessels Regulations and was originally made under a Commonwealth ordinance—the Machinery Ordinance 1949 No 11 (Cwlth).
The Australian Capital Territory (Self-Government) Act 1988 (Cwlth), s 34 (4) converted most former Commonwealth ordinances in force in the ACT, and the regulations made under them, into ACT enactments. This allowed the ACT Legislative Assembly to amend and repeal the laws. The Machinery Ordinance 1949 and the Boilers and Pressure Vessels Regulations were converted into ACT enactments on 11 May 1989 (self-government day).
As with most ordinances in force in the ACT, the name was changed from Ordinance to Act by the Self-Government (Citation of Laws) Act 1989 A1989‑21, s 5 on 11 May 1989 (self-government day).
This regulation was renamed under the Legislation Act 2001.
Before 12 September 2001, regulations commenced on their notification day unless otherwise stated (see Interpretation Ordinance 1937 s 16, Interpretation Act 1967 s 50, Subordinate Laws Act 1989 s 6).
