A judge has set a five-day trial for Hong Kong Cardinal, Joseph Zen Ze-kiun, and four other defendants who face charges under China’s stringent national security law.

It will take place Sept. 19-23.

The 90-year-old cardinal was detained May 11 and charged with failing to properly register a fund to offer financial assistance to those involved in anti-government protests in 2019. It was disbanded last year after coming under scrutiny by authorities.

The national security law made participating in or supporting the pro-democracy movement crimes of subversion and collusion with foreign organizations and allowed for those remanded to be extradited to mainland China. Punishment ranges between a minimum of three years and a maximum of life imprisonment.

All five defendants pleaded not guilty. If convicted of the improper registration, each defendant could incur a fine of about $1,300.

A longtime critic of the Chinese government, Zen drew Beijing’s ire for his continued critique of the Vatican’s controversial 2018 deal with China regarding the appointment of bishops.
