Uncertainty looms over Hong Kong’s legal sector as those at the helm of the city’s courts and the Justice Department are expected to leave within the term of the next chief executive. Among them will be Secretary for Justice Rimsky Yuen Kwok-keung – who handles all legal matters for the government – and Director of Public Prosecutions Keith Yeung Kar-hung. It is expected that Yuen will step down when the city’s next leader assumes office in July. “The current contract of Mr Keith Yeung, SC, will end on 8 September 2017,” the Department of Justice said. But it stopped short of commenting on Yuen’s situation. Local newspaper Sing Tao Daily reported that Yeung was expected to become a Court of First Instance judge, while Yuen would return to private practice. Another departure during the next chief executive’s term will involve Chief Justice Geoffrey Ma Tao-li , who will reach the retirement age of 65 in 2021. Commenting on the uncertainties, veteran barrister Ronny Tong Ka-wah said the changes might affect some constitutional matters being handled by the city, although it would not “turn the world upside down”. He shed light in particular on the role of the justice minister, who is expected to deal with sensitive constitutional issues ranging from electoral reform to immigration arrangements for the high- speed rail link between Hong Kong, Shenzhen and Guangzhou . Mainland immigration officers are likely to be stationed in Hong Kong, prompting fears about mainland laws being enforced in the city and their effect on the city’s autonomy. Teresa Cheng Yeuk-wah, 58, who heads the Hong Kong International Arbitration Centre, and Johnny Mok Shu-luen, who represented the government in a legal bid to unseat four lawmakers, are among those being tipped for the post of justice secretary. Tong said it would be important for the next justice secretary not to be too closely associated with Beijing because of the political nature of the role. However, he said he did not think the legal system would be affected much by the likely departures. The Legislative Council’s legal representative, Dennis Kwok, agreed with Tong, saying the rule of law “depends on our system and not individuals”.
