Lee and Chow were also leaders of the now-defunct Hong Kong Alliance (HKA).
The HKA was founded in May 1989 to support students holding pro-democracy rallies. Weeks later, the Communist Party crushed pro-democracy protests in Beijing’s Tiananmen Square with troops and tanks. Estimates of the death toll range from a few hundred to many thousands.
Over the next three decades, HKA called on authorities to accept responsibility for the crackdown, free dissidents and introduce democratic reform.
The Alliance’s leaders were charged in 2021 and have been behind bars since.
Rights group Amnesty International has said the case “relies on vague, overly broad and arbitrary definitions of ‘subversion'”.
Sarah Brooks, Amnesty International’s Deputy Regional Director, said Chow and Lee had “not committed any recognisable crime”.
“Chow Hang-tung and Lee Cheuk-yan are prisoners of conscience who should never have been prosecuted in the first place. They must be released immediately and unconditionally”, she added.
In a separate case, Chow was arrested in June 2021 for “inciting” the public to take part in that year’s vigil and later found guilty.
However, Hong Kong’s top court overturned that conviction in 2022, with a judge ruling the police hadn’t properly justified the vigil’s ban.
Chow Hang-tung spoke to the BBC in 2021, weeks before her arrest on 4 June 2022.
“I am prepared to be arrested. That is how Hong Kong is now,” she had said.
“I am willing to pay the price for fighting for democracy”.
