A number of statutory measures are in place to prevent the Equal Opportunities Commission from abusing its powers, the Secretary for Home Affairs, Michael Suen Ming-yeung, said. James Tien Pei-chun of the Liberal Party was worried that the commission would interfere in business operations if it were allowed to initiate formal investigations even when no complaint had been received. 'I want to know what mechanism the Government has to ensure that the commission will not abuse its investigative power,' said Mr Tien. Mr Suen said the commission had to draw up the terms of reference of any investigation, give general notice, and offer those under investigation an opportunity to make oral or written representations. 'Those measures are to ensure that a formal investigation will be conducted in a proper manner,' Mr Suen said.
