Yau Wai-ching and Baggio Leung placed their left hands on a blue-covered folder, not a bible, and mangled their oaths. During the Legislative Council swearing-in on October 12, 2016, the two Youngspiration party members pronounced China as 'Shee-na,' a derogatory term, and displayed a banner reading 'Hong Kong is not China.' They stretched the oath's syllables into a protest. On November 15, the High Court ruled their performances invalid and declared their seats vacant. The government's Department of Justice had argued the pair declined to swear allegiance, rendering them unfit for office.
The ruling was the first judicial enforcement of a Beijing-interpreted oath law. Just days prior, China's National People's Congress Standing Committee issued an active interpretation of Hong Kong's Basic Law Article 104, stating oath-takers must be 'sincere' and 'solemn.' The court applied this standard retroactively. The legal technicality of oath-taking became the mechanism for removing pro-independence voices from the legislature, setting a direct precedent for subsequent disqualifications.
Many viewed the event as a simple matter of parliamentary decorum. It was a constitutional earthquake. The case demonstrated Beijing's willingness to use legalist tools to define the limits of Hong Kong's promised 'high degree of autonomy.' It shifted the political battlefield from the streets and ballot box to the courtroom, where the government held a structural advantage. The principle of 'one country, two systems' was being delineated, with emphasis firmly on the first part of the phrase.
The lasting impact was the normalization of political disqualification. The ruling created a template. In the years that followed, dozens of opposition candidates were barred from elections, and other legislators were unseated under the same legal reasoning. It chilled political speech and narrowed the spectrum of acceptable dissent within Hong Kong's institutions. The two-minute oath on October 12 triggered a decade-long judicial reshaping of the city's political landscape.
