The Act states that it is the public policy of the state of Illinois "that its citizens shall be given . . . the right to attend all meetings at which any business of a public body is discussed or acted upon in any way. Exceptions to the public's right to attend exist only in those limited circumstances where the General Assembly has specifically determined that the public interest would be clearly endangered or the personal privacy or guaranteed rights of individuals would be clearly in danger of unwarranted invasion." 5 ILCS 120/1.
