THE Executive and Legislative Councils should ''keep their hands off'' prosecution-related issues, or the Legal Department's integrity would be jeopardised, legislator Andrew Wong Wang-fat warned yesterday. Mr Wong, a lecturer in government and public administration at the Chinese University, was concerned that the soon-to-be-established Legco legal panel might interfere with the working of the Legal Department's prosecutions division. If Exco and Legco were going to look at public prosecutions there was a risk the issue would become politicised, he said. Mr Wong was speaking at a meeting between legislators and Attorney-General, Jeremy Mathews on the setting up of a panel to monitor the Legal Department. Legislators hoped the Legal Department could become more accountable to Legco. They wanted the Attorney-General to disclose more information so they could be sure the Legal Department's decisions and advice were free of outside influence, such as political pressure. Mr Mathews, while welcoming the creation of the panel, made it clear that he would not draw on individual cases or disclose any legal advice his chambers gave to the Government. But he stressed that he was independent and the question of yielding to political pressure did not arise. Legislators also took the opportunity yesterday to air their grievances about the ''unco-operative'' attitudes of some law drafters. Appointed member Marvin Cheung Kin-tung said it was ''very frustrating to work with unco-operative law draftsmen''. They made legislative work ''much more tedious and time-consuming'', he said.
