Except in an emergency, as defined under section 2-101, the purchasing director shall not issue any order for delivery on a contract or
open market purchase until the office of the clerk of the circuit court and county
comptroller shall have certified, after preaudit, that there is to the credit of the
using agency concerned a sufficient unencumbered appropriation balance in excess of
all unpaid obligations in the current fiscal year in which the contract or open market
purchase is approved to defray the amount of such order for the goods or services
to be provided during that fiscal period. Using agency shall be responsible for ensuring
all future encumbrances for each budget year for all multi-year contracts.
