In a historic national security case involving 47 pro-democracy activists that has dragged on for more than a year, a Hong Kong court on Thursday loosened limitations on publishing pre-trial hearings.

The choice was made just one day after a reporting limitation was lifted for a different national security issue involving the civil society organization responsible for the yearly candlelight vigils held in Hong Kong to remember those who perished in the 1989 crackdown on Tiananmen Square.

The lifting of the reporting restrictions was seen as a breakthrough by some activists. It is the first time reporting will be allowed for pre-trial hearings for a national security case in Hong Kong.

Magistrate Peter Law, who had rejected previous applications to lift the reporting ban, did so on Thursday after being ordered to by a High Court judgein the interests of “open justice”.

“It is a fundamental principle of criminal justice … the public has the right to scrutinise whatever the court is doing,” one of the defendants, Gwyneth Ho, told the court in a July hearing.

Since the 47 democracy campaigners were arrested in a city-wide dawn raid in February 2021, the case has been repeatedly delayed as prosecutors requested more time to prepare, with only 13 of the defendants granted bail.

The campaigners have been accused of a conspiracy to commit subversion, after participating in an unofficial, non-binding primary election in 2020.

Government prosecutor Andy Lo had alleged the activists tried to cause an “acute crisis” and to paralyse government.

So far, 29 of the 47 have pleaded guilty, including legal scholar Benny Tai and activist Joshua Wong. Eighteen are pleading not guilty, including Gwyneth Ho, Owen Chow and Gordon Ng.

Despite the decision, some aspects of the proceedings, including bail hearings, will remain unreportable. Law also refused to clarify whether a preliminary inquiry initiated by Ng, to ascertain the strength of the prosecution’s case evidence before trial, would be reportable.

While the full trial date hasn’t been set, Hong Kong Justice Secretary Paul Lam has already ordered the case to be tried without a jury, citing a “real risk” that justice might be impaired, according to a document seen by Reuters. He also cited an unspecified “involvement of foreign factors” as a reason.

The trial will instead be heard by three judges designated by Hong Kong’s leader to handle national security cases.

“A hearing without a jury is unjust,” activist Owen Chow shouted at the end of the hearing on Thursday.
