Delegated Legislation.
Note: If all commenced amendments have been incorporated then that is the latest version available. An exclamation symbol alerts readers if there are commenced amendments that have not been incorporated. Sometimes this happens when there are a series of amendments commencing in quick succession. Even if the legislation publisher knows that amendments will commence at some future time, they cannot incorporate them into the text of the legislation until they have commenced.
Subscription databases and legislation websites offer a variety of different tools to help researchers identify and analyse legislation amendments and commentary surrounding them. Some also link legislation to case law and journal article citations, looking at how courts have interpreted the legislation.
Bound print copies of Commonwealth legislation are located on Level 4 of the Law Library.
