On May 16, Walter Kwok Ping-sheung sent an e-mail to staff of Sun Hung Kai Properties saying he had appointed his eldest son, Jeffrey, as his personal assistant, according to sources close to the situation. The notice was sent out just a day after Mr Kwok obtained an interim injunction from the High Court preventing the board from convening a meeting to remove him as chairman. Sources said the notice told the staff they could reach him by writing or speaking to Jeffrey, who had just completed his studies in the US. 'Jeffrey came to the office every day and also attended meetings chaired by Thomas and Raymond Kwok, but there were no odd feelings between them at all,' a source said. Walter Kwok also went to the office, even after the relationship with his two younger brothers had soured. 'But he only stayed for a short while and then left,' the source said. Meanwhile, the legal battle continued during the first open-court hearing of the case in the Court of First Instance yesterday when Walter Kwok applied for an extension of the injunction. The application was rejected by Madam Justice Susan Kwan Shuk-hing, but senior counsel Ronny Tong Ka-wah, for Mr Kwok, filed an appeal against her decision. Mr Kwok, who initiated the legal battle on May 15, is represented by Mr Tong and barristers Yvonne Cheng and Mike Lui. His two brothers have engaged a legal team led by senior counsel Adrian Huggins, with barristers Roxanne Ismail and Abraham Chan. The six legal representatives for the two sides are all barristers from Temple Chambers. Stewart Wong, a barrister representing two Sun Hung Kai Properties directors contesting the application for an extension, is also from the same chambers. The company is represented by senior counsel Ambrose Ho and barrister Michael Yin.
