In May 2012, Leung Kwok-hung, the only LSD member in the Legislative Council joined a weeks-long filibuster staged by Albert Chan and Wong Yuk-man, who were LSD legislators but defected to the People Power, 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.
