Use when building a delegated-legislation checklist for a Commonwealth instrument. The principal confirms that it is a legislative instrument. The checklist does not decide that it has been repealed.

## How AI may be used

AI may enter the registration date the principal supplies and show the section 50 anniversary arithmetic, without stating that the instrument is repealed or unenforceable.

**AI may:**

- Record the instrument name and the registration date from the register extract the principal supplies
- If registration was not on 1 January 2005, show the first 1 April or 1 October on or after the tenth anniversary
- If registration was on 1 January 2005, copy the matching row of the section 50(2) table

**AI must not:**

- Must not decide that the instrument is a legislative instrument
- Must not decide that section 50 has repealed it, or that Part 3 or sections 51, 51A, 53 or 54 do not apply
- Must not describe those other provisions

**The lawyer checks:**

- The principal confirms the instrument is a legislative instrument, using the definition that was not opened here
- The Federal Register extract is the source of the registration date
- Part 3 and sections 51, 51A, 53 and 54 are opened before anyone relies on the repeal day
- Section 15G was not opened, so the explanatory-statement duty is not described beyond section 15K(2)
