30 ILCS 230/2A.2
No officer or employee of this State shall create or maintain or participate in a trust fund or bank or savings and loan association deposit of any money received by him by virtue of his office or employment except as provided by law. Any such officer or employee who on the effective date of this amendatory Act of 1961 has in his possession, or after such effective date receives, money under conditions which do not require payment thereof into the State Treasury, but which he is authorized by law to receive and hold in a trust fund or bank or savings and loan association deposit outside the State Treasury, shall immediately submit a report to the Auditor General identifying the trust fund or bank or savings and loan association deposit as well as the depository in which it is maintained.
If any such officer or employee receives or has in his possession money under conditions which do not require payment thereof into the State Treasury, and there is no trust fund or bank or savings and loan association deposit authorized by law for the receipt thereof, he may, upon the written approval of the Governor and the State Comptroller, establish a temporary trust fund or bank or savings and loan association deposit which shall be legal until the thirtieth day after the sine die adjournment of the next regular session of the General Assembly. A copy of such written approval shall immediately be forwarded by the Comptroller to the Auditor General.
As soon as the next regular session of the General Assembly has organized for the transaction of business, a complete report concerning each such temporary trust fund or bank or savings and loan association deposit shall be filed, by the State officer or employee having charge thereof, with the presiding officer of each house of the General Assembly. If such General Assembly does not, by law, authorize the continuance of the trust fund or bank or savings and loan association deposit so required to be reported, the money in such temporary trust fund or bank or savings and loan association deposit shall be deposited in the general revenue fund in the State Treasury.
