Hon GRANT ROBERTSON (Minister of Finance): As the member I'm sure is aware, there are already conditions attached to the authority granted under an imprest supply bill. This is because every Government going back to 1989 has had multiple imprest supply bills in each financial year, and the process around them is well established. Specifically, any expenditure incurred under the authority of the Imprest Supply (Second for 2021/22) Bill will need to be appropriated by Parliament before the end of the 2021-22 financial year. Authority under an imprest supply Act also only relates to the period a particular Act is in force. The authority granted by the first imprest supply bill for 2021/22 is repealed by the passing of the main appropriations bill. The second imprest supply bill, which is generally passed alongside the main appropriations bill, as we intend to do later today, is generally repealed by the supplementary estimates bill. If the member casts his mind back some months, he will recall that we did just that on Budget day 2021. For further assistance in this particular point, the member may find the current edition of McGee an invaluable resource in this regard.
