Hong Kong’s Department of Justice (DoJ) has lost its appeal against a lower court’s decision to acquit former lawmaker Lam Cheuk-ting of a perverting the course of justice charge linked to the 2019 protests and unrest.

A panel of three Court of Appeal judges delivered the judgment on Friday, upholding a previous ruling that found Lam and two co-defendants not guilty.

The case relates to a confrontation after a protest at Tuen Mun Park on July 6, 2019, about a month after large-scale demonstrations began.

Lam and two others were accused by the prosecution of pressuring a man, known to the court as X, to delete images on his phone.

Protesters suspected that X had taken close-up photos of protesters at a July 1, 2019 protest outside the police headquarters in Wan Chai.

Lam was charged with perverting the course of justice, while a co-defendant, social worker Aggie Chung, was charged with criminal damage and accessing a computer with dishonest intent.

A third co-defendant, journalist Ronnie Tsang, was also charged with perverting the course of justice as well as participating in an unlawful assembly.

Besides Tsang’s unlawful assembly charge, a District Court judge acquitted the defendants of all the offences in January 2023.

The judge, Douglas Yau, said in 2023 that Lam was acting as a peacemaker to defuse a tense situation, and that he was only trying to get X out of danger when he asked him to let protesters check his phone after being surrounded.

Handing down the judgment on Friday, Court of Appeal judges Derek Pang, Keith Yeung, and Judianna Barnes sided with the District Court judge.

The judges said that while the deletion of pictures would be an obstruction of police investigations and legal procedures, there was no way to confirm whether those pictures actually existed in the first place.

Lam, a former member of the now-defunct Democratic Party, is currently serving time after being found guilty in the Hong Kong 47 proceedings, the city’s largest national security case.

He and dozens of other activists were convicted in May 2024. Lam, who had pleaded not guilty, was sentenced to six years and nine months in prison.
