One member of a student activist group has won bail ahead of her trial on subversion charges under the national security law, but three of her three co-defendants were sent back to jail on Friday. Chu Wai-ying, 18, an ex-spokeswoman for Student Politicism, was granted bail at the High Court by Mr Justice Alex Lee Wan-tang, having spent 24 days on remand after being charged last month. Bail was set at HK$15,000 plus surety of HK$10,000, with the conditions that Chu surrender her travel documents, remain in Hong Kong, live at the address given, obey a daily curfew and report to police three times a week. Chu was also told not to engage directly or indirectly in conduct which could reasonably be regarded as capable of constituting an offence endangering national security, and not to attend or give any interviews, post on social media, or meet any representatives from foreign governments. But Lee threw out the other bail applications from the group’s former convenor, Wong Yat-chin, and former secretary, Chan Chi-sum, both 20, as well as its former spokeswoman, Wong Yuen-lam, 19. The four have been charged with conspiracy to incite subversion of state power, an offence which carries a maximum jail sentence of 10 years. They were previously denied bail by acting chief magistrate Peter Law Tak-chuen and Principal Magistrate Don So Man-lung, who along with Lee have been designated to handle national security cases. Second mega court for Hong Kong protest cases to have 250-person capacity Prosecutors claim the defendants conspired to incite others to commit acts to overthrow or undermine “the basic system of the People’s Republic of China”, as well as “the body of central power of the People’s Republic of China or the body of power of the Hong Kong Special Administrative Region”. The group disbanded following the prosecution. All four defendants are expected to return to West Kowloon Court on November 3, before the case is moved to the higher District Court, where sentences go up to seven years. The Beijing-decreed national security law, imposed on Hong Kong in June last year, also bans acts of secession, terrorism and collusion with foreign forces.
