The Governor shall appoint one member from each chamber of the General Assembly to serve as a liaison representative and one member from each chamber to serve as the liaison representative’s alternate. The 2 liaison representatives shall not be members of the same political party, nor shall a liaison representative’s alternate be a member of the same political party as the liaison representative for whom he or she is an alternate. The terms of the liaison representatives and alternate liaison representatives appointed by the Governor shall be 2 years, commencing on the second Wednesday of January in odd numbered years, except that the terms of the liaison representatives and alternate liaison representatives initially appointed by the Governor under this Section shall commence on the date of their appointment and expire on the second Wednesday of January, 1993. Vacancies shall be filled by appointment of the Governor for the unexpired term, and the person appointed to fill a vacancy shall be a member of the same chamber of the General Assembly and the same political party as his or her predecessor in office. The liaison representatives, or their alternates who meet with the Board of Directors of the Illinois High School Association at any meetings of that Board which the liaison representatives are unable to attend, shall communicate to the members of the General Assembly information of importance to the cooperative relationship between the Illinois High School Association and the General Assembly. It shall be the responsibility of the Illinois High School Association to timely supply to both liaison representatives and both alternates all agenda materials and information that are customarily supplied by that Association to the members of its Board of Directors for use in connection with the meetings of that Board.
