In 2019 amid the historic anti-extradition protests and the pro-democracy landslide in the District Council elections, legal scholar Benny Tai, one of the initiators of the 2014 Occupy protests, put forward a plan for the pro-democrats to win a majority of the seats in the Legislative Council to block the government's bills including the expected legislation of the Article 23 of the Basic Law which would in turn put pressure on the government to implement the five key demands of the protest movement. Based on prior experience, where excessive numbers of candidates split the pro-democratic votes in the 2016 election, he proposed a primary election within the pro-democracy camp to maximise the chance for the pro-democrats to win more seats by setting a limit on the numbers of candidates and avoid wasting votes.
