There is hereby created a revolving fund for the department of attorney general to be known as “The Attorney General’s Court Costs Fund”, which shall consist of money transferred by the general assembly of the state of Missouri from the general revenue fund to be credited to such fund, and any money paid into the state treasury and required by law to be credited to such fund. This fund shall be kept separate and apart from all other moneys in the state treasury and shall be paid out by the state treasurer upon warrants issued by the state auditor as certified to by the commissioner of administration, upon verified vouchers of the attorney general. Such money, after appropriation pursuant to law, shall be available only for the making of deposits and the payment of court costs incurred in any litigation, suit or hearing pending or which may hereafter be pending in any state or federal court or tribunal in which it is the duty of the attorney general to prosecute, defend or appear; provided, however, that such deposits and costs as may be awarded or refunded to the state at the termination of any such litigation, suit or hearing shall be deposited in the state treasury to the credit of the attorney general’s court costs fund.
