曾鈺成
In May 2012, Albert Chan and Wong Yuk-man staged a weeks-long filibuster by submitting 1306 amendments altogether to the Legislative Council (Amendment) Bill 2012, by which the government attempted to forbid resigning lawmakers from participating in by-elections as the government's response to the "Five Constituency Referendum movement" launched by the LSD in 2010. On the morning of 17 May 2012, Jasper Tsang Yok-sing, President of the Legislative Council adopt Article 92 of the Standing Order, which allows the president follow foreign parliament rules for unregulated behaviours to terminate the debate. In the end, all amendments were defeated and the Bill was passed.
