The last by-election was held on 10 December 2000, when then DAB vice-chairman Gary Cheng declined to accept his seat as a result of a scandal. The current leader of the Civic Party, Audrey Eu, who was then running as an independent backed by the pro-democracy camp won the by-election with 52.1% of valid vote. Cheng was subsequently jailed for abuse of office.
