The powers and duties of the Auditor General under this Act and the system of audits established by this Act are in addition to any other powers, duties or audits required or authorized by law.
Where records or information are classified as confidential, by or pursuant to law, such records or information shall be disclosed to the Office of the Auditor General as necessary and to the extent required for the performance of an authorized post audit. Federal tax information shall only be provided in accordance with federal law and regulation applicable to the safeguarding of federal tax information.
Confidential records or information disclosed to the Office of the Auditor General shall be subject to the same legal confidentiality and protective restrictions in the Office of the Auditor General as such records and information have in the hands of the official authorized custodian. Any penalties applicable to the officially authorized custodian or his employees for the violation of any confidentiality or protective restrictions applicable to such records or information shall also apply to the officers, employees, contractors, and agents of the Office of the Auditor General.
The Office of the Auditor General may not publish any confidential information or records in any report, including data and statistics, if such information as published is directly or indirectly matchable to any individual.
Inside the Office of the Auditor General, confidential records or information may be used only for official purposes.
Any officer, employee, contractor, or agent of the Office of the Auditor General who violates any legal confidentiality or protective restriction governing any records or information shall be guilty of a Class A misdemeanor unless a greater penalty is otherwise provided by law.
Where this Act expressly governs or grants authority for regulations to govern other auditing procedures, this Act supersedes all other statutes to the contrary. To the extent that this Act conflicts with another statute, this Act prevails.
Except as provided in this Section, this Act does not supersede or repeal by implication any other statute.
