R&R ad hoc committee

Hello everyone,
The Chairman of the Violations Committee, who is also a Board Member, has set up a committe to "re-vamp" the rules and regulations. Their first meeting is this week but no notices have been posted. I was told by the Property Manager that this is not an "open" meeting. We live in Illinois, can anyone confirm that this meeting should be open by law?
Thanks,
Georgia
