Where the exercise of a function, right or power involves incurring an expense or creating a financial obligation, legal authorisation to exercise that function, right or power is not the only requirement that must be met. Generally, the government party is subject to legislation or policies regulating financial commitments, under which the person exercising the function, right or power must also have the capacity to make the financial commitment resulting from the exercise of the function, right or power. For example, the ability of staff of certain public authorities and bodies to make financial commitments is subject to regulations and directions under the Financial Management Act 1994 (including the Minister for Finance's Standing Directions). Approval may also be required from the relevant Cabinet Subcommittee.
