56 Ill. Adm. Code 280.230
Incomplete Complaint
Section 280.230 Incomplete Complaint
If the Department receives a complaint from an individual that
complies substantially with Section 280.210 but is lacking an element that
still must be provided, the Department may accept and docket the complaint as
an incomplete complaint. The Department shall notify the complainant, in
writing, of the elements that must be supplied. If the complainant is
unavailable or unwilling, without good cause, to perfect the complaint within
30 calendar days, the Department may make a finding of a failure to cooperate
or may deem there to be a waiver of all proceedings before the Director.
