On 12 October 2016 the inaugural meeting of LegCo, Sixtus Leung and Yau Wai-ching used the oath-taking ceremony as a platform to protest, by claiming that "as a member of the Legislative Council, I shall pay earnest efforts in keeping guard over the interests of the Hong Kong nation," displaying a "Hong Kong is not China" banner, and mispronouncing "People’s Republic of China" as "people’s re-fucking of Chee-na".

[3] Chief Executive Leung Chun-ying and Secretary for Justice Rimsky Yuen took the unprecedented step of launching a judicial review seeking the disqualification of the duo.

[9] In Kowloon West, the candidates were Frederick Fung of the Hong Kong Association for Democracy and People's Livelihood (ADPL), Ramon Yuen of the Democratic Party, Occupy activist Ken Tsang and disqualified legislator Yiu Chung-yim, which Tsang subsequently withdrew from the primary to support Yiu; in New Territories East, the candidates were Gary Fan of the Neo Democrats, Kwok Wing-kin of the Labour Party and former president of the Chinese University of Hong Kong Students' Union Tommy Cheung.

[11] Agnes Chow, Demosistō standing committee member, emerged as the party's and the pro-democrats' sole candidate in the Hong Kong Island by-election after Nathan Law's girlfriend Tiffany Yuen reportedly declined to run.

The European Union issued a statement warning that banning Chow from the by-election "risks diminishing Hong Kong’s international reputation as a free and open society".

[15] Yiu Chung-yim, who was rumoured that his candidacy could be foiled on the basis of National People's Congress Standing Committee interpretation of the Basic Law being applied to the entire term of the current legislature, survived the disqualification.

[16] The candidacies of two other localists, Sha Tin District Councillor James Chan Kwok-keung and convenor of the Shatin Community Network Ventus Lau Wing-hong who ran in the New Territories East, were also disqualified by the returning officer Amy Chan Yuen-man on the grounds that they had advocated Hong Kong independence, even though Lau had earlier made a declaration suggesting he no longer supported the idea.

The result in the Kowloon West constituency was a surprise reversal as Vincent Cheng of the Democratic Alliance for the Betterment and Progress of Hong Kong (DAB) narrowly defeated pro-democrat independent Yiu Chung-yim by a margin of 1.1 per cent.

[36] Yiu requested a recount at 5am but only confirmed his defeat in the constituency, which made it the first time the pro-Beijing camp received greater vote share than the pro-democrats in a geographical constituency since the 2000 Legislative Council election in Kowloon East where DAB's Chan Yuen-han and Chan Kam-lam topped the poll with a margin of 2.1 per cent compared to the Democratic Party's Szeto Wah and Fred Li.

[44] The decisions meant that the winners of the Hong Kong Island and New Territories East, Au Nok-hin and Gary Fan, were not duly elected and therefore lost their seats.
