HONG KONG (Reuters) -A Hong Kong court found three prominent pro-democracy activists guilty on Thursday over an unauthorised assembly on June 4 last year to mark Beijing's 1989 crackdown on protesters in and around Tiananmen Square.
Hong Kong has traditionally held the world's largest annual June 4 vigils, as part of wide-ranging freedoms promised when it returned to Chinese rule in 1997, but applications to hold the vigils this year and in 2020 were rejected by police.
The ruling against media tycoon Jimmy Lai, barrister Chow Hang-tung and former opposition politician Gwyneth Ho is the latest blow to the democracy movement, in which scores of activists have been arrested, jailed or fled since Beijing imposed a sweeping national security law.
Lai, Chow and Ho had pleaded not guilty to the charges linked to the gathering on June 4, 2020.
Prosecutors had been "able to prove beyond reasonable doubt" that Lai and Chow had incited others to attend the vigil, District Court Judge Amanda Woodcock wrote in her judgment.
These efforts included an appeal by Chow for people to "light candles" across Hong Kong, including at the vigil site of Victoria Park.
Lai was found guilty after spending 15 minutes in the park in what Woodcock called a "deliberate act to rally support for and publicly spotlight the unauthorised assembly that followed", even if he did not speak.
Ho was found guilty of participating in an unauthorised assembly.
During the trial, Chow, a former leader of the now disbanded Hong Kong Alliance in Support of Patriotic Democratic Movements in China, had argued the annual vigil was "their right, their freedom".
The police, however, rejected the Alliance's application after taking into account the advice of government medical experts regarding COVID risks and that a mass gathering was "not recommended", according to the judgement.
Ho earlier told the court that "remembrance is resistance", adding that she only went to the site to test the difference between Hong Kong and mainland China, where any commemoration of June 4 is taboo and can lead to imprisonment.
Sentencing will be delivered on Dec. 13.
Sixteen other activists are already serving sentences of between four and 10 months for the same incident.
After mass pro-democracy protests in 2019, China imposed a sweeping national security law that punishes offences such as subversion and secession with jail terms of up to life.
Critics, including the U.S. government, say the law has been used as a tool to erode the city's freedoms and quash dissent, but Beijing says it has brought stability and order to the financial hub.
Chow and several former leaders of the now disbanded Alliance, which had long sought to "end one-party rule", have also been charged with inciting subversion under the new law.
China has never given a full account of the 1989 crackdown. Days later officials put the death toll at about 300, most of them soldiers, but rights groups and witnesses say thousands of protesters may have been killed.
