What it does
The Crimes Regulations 2019 is a legislative instrument made under the Crimes Act 1914 (Cth), consolidating and replacing the Crimes Regulations 1990. As stated in section 3, the instrument is made under the Crimes Act 1914 (with Division 2 of Part 11 made under the Crimes Legislation Amendment (Serious and Organised Crime) Act 2010).
Its function is not to create new criminal law. Instead, it handles the administrative machinery that makes the Crimes Act's operational provisions work: prescribing forms, identifying corresponding State and Territory laws for cooperative law enforcement schemes, setting out who is qualified to conduct forensic procedures, and managing which organisations and laws are excluded from, or included in, the spent convictions framework.
