Retired Catholic leader Cardinal Joseph Zen Ze-kiun and five others will appear before a Hong Kong court on Tuesday to answer charges of failing to register a now-defunct fund that provided financial assistance to protesters facing legal troubles stemming from the 2019 social unrest. The 90-year-old former bishop, four other trustees of the 612 Humanitarian Relief Fund and its secretary will stand before West Kowloon Court at 10.30am after police served them with summonses. Officers from the police’s National Security Department earlier this month arrested Zen, singer Denise Ho Wan-sze and former Lingnan University academic Hui Po-keung, as well as ex-opposition lawmakers Margaret Ng Ngoi-yee and Cyd Ho Sau-lan, who is already in jail for her role in illegal assemblies. They were held on suspicion of colluding with foreign forces in relation to their work with the fund, but no charges were laid. While Cyd Ho remains in custody, the force on May 12 said the other four suspects had been released. The arrest of Zen was condemned by Western governments, while the Vatican said it was monitoring developments in the case carefully. Police applied to the court to serve summons to the five and 37-year-old Sze Ching-wee, who a source said served as secretary for the fund, for allegedly failing to register the fund with the government. Hong Kong Catholic leader, activist Joseph Zen knew he might be arrested one day Under the Societies Ordinance, a local society or its branch must apply to the Societies Officer for registration or exemption within one month of its establishment or else the responsible person could be fined HK$10,000 upon a first conviction. Subsequent conviction risk jail terms as long as three months. Since it was founded in 2019, the 612 Humanitarian Relief Fund has distributed more than HK$243 million (US$31.2 million) to protesters facing prosecution or financial hardship as a result of the social unrest. The fund announced it would close in October 2021 given “the current political environment”, but abruptly stopped taking donations a month earlier than expected after police opened an investigation into its activities for suspected breaches of the national security law .
