Yau Wai-ching

On 26 August 2017, the Court of Final Appeal of Hong Kong refused to appeal the case as they did not have a reasonably arguable case. Leung and Yau were found to have manifestly refused and wilfully omitted to take their oath – an act classed as declining and neglecting it.

Representing Youngspiration in the 2016 Legislative Council election, she won the sixth and final seat in the Kowloon West geographical constituency. With 20,643 votes, Yau Wai Ching edged out incumbent Wong Yuk-man to become the youngest female member of the Legislative Council, and its second-youngest ever member, behind fellow-localist Nathan Law, who won in the same election, on Hong Kong Island.

On 12 October 2016 in the first meeting of the session, Yau and her party colleague Baggio Leung inserted their own words into the official script and had their oaths rejected. They were criticised for pronouncing China as "Jee-na", a term considered derogatory since the Second Sino-Japanese War, and Yau mispronounced "People's Republic of China" as "people's re-fucking of Jee-na". As a result, their qualification as legislators were challenged by the government in court. The National People's Congress Standing Committee (NPCSC) intervened in the court case by interpreting Article 104 of the Basic Law of Hong Kong to "clarify" the provision of the legislators to swear allegiance to Hong Kong as part of China when they take office, by insisting oath taking be conducted sincerely and accurately, and later stating that China would firmly oppose Hong Kong independence. On 15 November 2016, the court disqualified the two legislators on the grounds they did not take their oaths "faithfully and truthfully".

She is a member of Youngspiration, a localist group formed by young people after the Umbrella Revolution. Youngspiration fielded nine candidates in the 2015 District Council elections, in which Yau ran against legislator Priscilla Leung in Whampoa East. As a newcomer, Yau received 2,041 votes, only about 300 votes less than Leung. After the district council election Yau served as Kwong's assistant and Youngspiration's Whampoa community officer.

Regine Yau Wai-ching (Chinese: 游蕙禎 ; born 6 May 1991) is a Hong Kong politician. She is a member of the localist group Youngspiration. She was elected to the Legislative Council of Hong Kong as a member for Kowloon West in the 2016 Legislative Council election, but has since been disqualified pursuant to a judgement delivered by the High Court on 15 November 2016.

Yau was born on 6 May 1991 at St Teresa's Hospital in Kowloon City, Hong Kong to a middle-class family. Both her parents are civil servants. Her father was a technical officer in the Hong Kong government. She was educated at Queen Elizabeth School and studied Chinese language at Lingnan University. She was an intern at Ta Kung Pao newspaper during her study.
