Seniors John Clark and Andrew Wagner were expelled Oct. 30 due to excessive unexcused absences -- a chronic problem in Congress, student leaders have said.
After any Congress member has been absent from three full Congress or committee meetings, charges can be brought against them if at least three members vote to do so.
The Ethics Committee then considers the charges and decides whether to bring them to a full congressional vote.
David Ruddell, Ethics Committee chairman, said he does not have full attendance records from committee meetings but that there are three people who would be eligible for expulsion from Congress if they miss the next full meeting Nov. 13.
A simple majority of representatives in attendance constitutes a quorum, which is needed to conduct official business.
Before his expulsion, Clark represented District 10, which covers Alderman, McIver, Spencer, Stacy and Graham Residence Halls, and Wagner represented District 21, which includes the area bounded by Columbia Street, West Franklin Street, Jones Ferry Road and the N.C. 54 bypass.
The new expulsions bring the number of empty seats in Congress to 13 out of the total 37. A total of 10 districts at the graduate and undergraduate level are without representation.
Speaker of Congress Mark Townsend said he hopes the special election will fill all empty seats, but he is not optimistic.
"Ideally, I'd like all 37 seats to be filled to represent UNC," Townsend said. "On the other hand, there's nothing I can do if apathy is so rampant."
