Legislation Act 2003
The Office of Parliamentary Counsel must generally deliver a legislative instrument for laying before each House of the Parliament within 6 sitting days of that House after the instrument is registered (with the instrument ' s registered explanatory statement, if applicable).
A legislative instrument (or a provision) may be disallowed by either House within a certain time after the instrument is tabled. A legislative instrument is taken to be repealed if it is disallowed. Some legislative instruments are required to be tabled in Parliament, but are not subject to disallowance.
