Jackson Kwan San-wai, who ran at the head of the Politihk Social Strategic list in the same constituency as Lau but lost, with his list (of two) gaining only 938 votes (0.34%), filed an election petition against Lau in November 2016 on the grounds that by her conduct during the swearing-in she did not uphold the Basic Law. Politihk Social Strategic is a group of pro-Beijing activists who opposed the 2014 pro-democratic protests. It was followed by the government launching a second legal action, against her and three other legislators, Leung Kwok-hung of the League of Social Democrats (LSD), Nathan Law of Demosisto and Yiu Chung-yim, on 2 December. The four members were eventually disqualified by the court on 14 July 2017.
