The Judiciary released a statement on Wednesday evening and expressed grave concerns about the recent repeated incidents involving intimidations against judges and judicial officers. It added the cases have been reported to police.

As for the suspicious letters addressed to judges, the judiciary has strengthened security measures and asked Hongkong Post to screen postal items addressed to court buildings before delivery so that suspicious postal items could be reported and handled by police.

Outdoor checkpoints for postal items will also be set at suitable locations of court buildings to minimize the impact of suspicious mail on court security and operations.

The judiciary added police and security support for court buildings will be enhanced and it will remind staff and security personnel to stay vigilant to ensure a timely response to security incidents.

It also said security screening has been put in place at the Court of Final Appeal Building, those floors with courtrooms at the High Court Building, the Family Court and the Small Claims Tribunal. The measure will be extended to the West Kowloon Law Courts Building by the end of this year.

The judiciary reiterated that as stated in the Basic Law, Hong Kong enjoys independent judicial power, including that of final adjudication, and Hong Kong courts shall exercise judicial power independently, free from any interference.
