The Secretary for Justice will have to decide if the provisional legislator who sent first-day covers to about 500 Election Committee members had broken the law, the electoral watchdog said last night. Electoral Affairs Commission chief Mr Justice Woo Kwok-hing said that since Lo Suk-ching, who was seeking a seat through the Election Committee, had on Monday withdrawn from the race because of the row, the electoral commission would not investigate. The case would be left to the Independent Commission Against Corruption and Secretary for Justice Elsie Leung Oi-sie. 'We are responsible for matters related to elections. If Mr Lo is not standing, what is the point of us studying whether he offends the law?' Mr Justice Woo asked. Mr Lo, of the New Territories Association of Societies, was criticised for sending out the first-day covers, which were to mark the opening of the National People's Congress plenum in March. Mr Justice Woo said other candidates should take notice of Mr Lo's case. He also said officials need not avoid attending functions where candidates were present, unless it was him or Tung Chee-hwa. 'Mr Tung and I are important because people might think we favour particular candidates,' he said. Concern was raised last week when Secretary for Home Affairs David Lan Hong-tsung attended a function hosted by the New Territories West candidate, Tai Kuen.
