Lau's performance in Legco was considered one of the worst as he had not initiated a motion since 1998. His only motion was on 4 December 2013 against the incorporation of Tai Long Sai Wan into Country Park but was defeated. In 2009 and 2010, Lau supported the disputed HK$66.9 billion funding of Express Rail, and advocated the controversial reform of methods for selecting the CE and LegCo. In 2014, Lau was awarded top position in the no-show charts in his participation of the Legislative Council. His attendance rate at work had stirred up concern that he was actually deceased given his age. From 2004 to 2016, he was the oldest member in the Legislative Council.
