Before approving any proposed expenditure of relevant money a Minister must have made reasonable inquiries and be satisfied that the spending would be a proper use of relevant money, that is efficient, effective, economical and ethical. Having approved, the Minister must commit the terms of the approval to writing as soon as practicable and observe any further rule requirements on expenditure approvals. In a Parliamentary Department the duty falls on the Presiding Officer responsible for the expenditure, or on both Presiding Officers jointly where responsibility is shared. Neither the Finance Minister nor the Treasurer may delegate this power.
