Section 50 ILCS 320/2 - Policy and purpose(a) It is the public policy of this State, in order to provide for the public health, safety and welfare, to provide assistance to units of local government in the formulation and implementation of proper financial accounting procedures, budgeting and taxing practices.(b) The purpose of this Act is to assure fiscal integrity of all units of local government so that they may provide for the health, safety and welfare of their citizens, pay when due principal and interest on their debt obligations and meet financial obligations to their employees, vendors and suppliers. The failure of a unit of local government to so act is hereby determined to affect adversely the health and safety and welfare not only of the people of the unit of local government, but also of the people of the State of Illinois.(c) This Act is an Omnibus Bond Act within the meaning of Section 8 of the Statute on Statutes. No provision of this Act shall be deemed to apply if such application shall result in the impairment of a contract made prior to the effective date of this Act with any person, other than the governmental entities named in Section 7 of this Act. Any person not such a governmental entity shall continue to be able to enforce any rights assigned to or otherwise pledged to or for the benefit of such person by such entity.
