LEGISLATORS decided to set up their own inquiry into labour disputes on airport-related projects, even though the Government is conducting an investigation. The main parties, except for the Democratic Alliance for the Betterment of Hong Kong, gave their support despite a warning that the move might hinder the administration's inquiry and the promise that a full report would be released in three months. With a vote of 46 to six, the council decided to follow trade unionist Lau Chin-shek's proposal to form a sub-committee under the manpower panel. It is empowered to summon witnesses and documents to the hearings. But the Secretary for Education and Manpower, Joseph Wong Wing-ping, said an independent inquiry by Legco would only lower the chances of a successful government investigation. He reminded members that the Labour Department, Immigration Department and the police force were looking into the alleged wage deductions from overseas workers. He said the administration was ready to prosecute in some cases. 'If Legco conducts a hearing at the same time, there will be a severe impact on the normal investigation.' Stressing that the Chinese and the Hong Kong governments were trying hard to seek the truth, Mr Wong also promised members that a full report would be released after three months. Mr Wong ensured members the whole process of the investigation would be made 'open and transparent'. Mr Lau, also a Democratic Party member, said: 'The monitoring work conducted by the Government is disappointing.' Liberal Party spokesman James Tien Pei-chun said: 'I don't believe it's the intention of large companies and contractors to take money from workers' wages.' Three of the alliance's six members abstained in the voting and another six members voted against the resolution.
