Illinois Statutes Chapter 30. Finance § 5/3-5. Special studies for the General Assembly

(a) reviews and analyses of post audits and investigations previously completed by the Office of Auditor General;

(b) reviews and analyses of audits and financial or fiscal studies as they relate to public funds of the State; or

(c) reviews and analyses of reports and data in the State Comptroller's office and the State Treasurer's office.

To the extent that manpower and funds are available to his office for that purpose, the Auditor General shall conduct special studies but shall afford them a lower priority than such post audits and investigations as are required or directed under this Act.

In connection with such special studies, the State Treasurer and the State Comptroller shall provide the Auditor General with such reports and data maintained by their offices as may be requested by the Auditor General and, at the request of the Auditor General, shall develop and provide such additional reports as are capable of being provided with data processing facilities ordinarily utilized by their offices. The costs of such additional reports shall be borne by the Treasurer or the Comptroller, as the case may be.
