This Act applies to all accounts or claims owed to "State agencies", as that term is defined in the Illinois State Auditing Act, except that the debt collection and write-off provisions of this Act shall not apply to the Illinois State Scholarship Commission in the administration of its student loan programs. To the extent that some other statute prescribes procedures for collection of particular types of accounts or claims owed to State agencies in conflict with the provisions of this Act, such other statute shall continue in full force and effect. The debt collection and write-off provisions of this Act may be utilized by the General Assembly, the Supreme Court and the several courts of this State, and the constitutionally elected State Officers, at their discretion. However reporting requirements established by the comptroller shall be followed by all State agencies. The provisions of this Act shall be utilized at all times by all departments, agencies, divisions, and offices under the jurisdiction of the Governor.
