After the 2010 by-election, the government considered the resignations were abusive to the system and planned to plug the loophole. A Legislative Council (Amendment) Bill 2012 was proposed to disqualify a resigned member of the Legislative Council from participating in a subsequent by-election. Leung participated in the filibustering against the bill with Albert Chan and Wong Yuk-man, submitting 1,306 amendments altogether, which began the radical democrats' filibustering practice against the government bills in the following years. On morning of 17 May 2012, LegCo President Jasper Tsang, adopted 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 on 1 June 2012.
