EXPERTS from China and Britain will find it hard to bridge the gap on the Court of Final Appeal Bill when they meet for two days of talks starting today, a government source said last night. The lack of trust between the two sides in the Sino-British Joint Liaison Group experts' meeting made it difficult for either side to meet each other's demands, the source said. Mutual suspicion between the two sides was encapsulated in the row over how to define 'acts of state', over which the court would have no jurisdiction. 'The Chinese suggestion of regarding issues concerning Hong Kong and the central authorities as acts of state is unacceptable to the British side,' the source said. It would be equally difficult to convince China to accept the common law version of 'act of state', the source added. If no agreement was reached, there could be another session next month but it would depend on whether any progress had been made, the source said. Paul Tang Kwok-wai, Deputy Director of Administration, hoped the expert session would be the last round of talks on the bill. Everyone knew time was running out for the bill, he said, and that it would have to be enacted soon to set up the court on time. Mr Tang declined to say whether this was a government deadline, saying only the Government was committed to tabling the bill to the Legislative Council in this session, which ends in July. China accused Britain yesterday of playing 'little tricks' over the court. The motion debate moved by legislator Jimmy McGregor was seen as the latest manoeuvre by the British, the People's Daily said.
