LEGISLATORS yesterday deferred approval of the Legal Department's localisation scheme because of lack of information. Members of the establishment sub-committee were not convinced of the need to create six consultancy posts and other senior posts under the scheme. The scheme aims at achieving 50 per cent localisation in the senior levels and 60 per cent localisation overall by the end of 1995. United Democrat Cheung Man-kwong said the six separate papers submitted failed to show what the overall structure of the department would be like after the new posts were introduced. Independent legislator Emily Lau Wai-hing asked the department to provide a paper showing an organisation chart and a comprehensive report of the impact of the posts. Mr Cheung said consultancy posts were a way to evade Legco scrutiny, as they were not part of the civil service. Attorney-General Jeremy Mathews said it was not the Government's intention to bypass Legco and made the assurance that candidates would be hired solely on suitability. He also rejected Mr Cheung's allegation that the posts were created to accommodate expatriate officers, saying that they would be confined to specific tasks for a short duration, two to three years at most. But Mr Cheung asked: ''If they are needed only for two or three years, why does the Government not hire contractual staff instead?'' Miss Lau was worried that some inexperienced staff would be promoted under the new localisation scheme. ''I'll be alarmed if the lawyers in the Legal Department could climb faster compared to a normal administrative officer in other departments.'' Mr Mathews assured legislators that promotion would be based strictly on merit and quality. ''It is not something automatic and I'm sure that each of them will have all the attributes necessary for promotion,'' said Mr Mathews. United Democrat Lee Wing-tat asked whether the department had overstated the situation, and hence whether the proposed posts were necessary. Mr Mathews responded: ''The posts were absolutely necessary and if we don't get the resources, we're in real difficulties in getting the work done.'' The sub-committee agreed to discuss the matter early next month.
