The Legislative Council yesterday deliberated the bill on the Legislative Council vacancy replacement arrangement through the night. There was a stand-off between those who supported and opposed filibuster at the protest zone outside the Legco. The scene was once chaotic. Secretary for Constitutional and Mainland Affairs Raymond Tam Chi-yuen said staff had been stationed at the Legco on shift duty to ensure a quorum, stressing that the government would not withdraw the bill. Liberal Party chairperson Miriam Lau Kin-yee, together with seven other members, fasted 30 hours in protest of filibuster, saying the tactic was a form of parliamentary hegemony.
