THE Assistant Commissioner of the Correctional Services Department (CSD), charged with using false documents in an attempt to migrate to Australia, was responsible for liaising between the CSD and the ICAC, Eastern Court heard yesterday. So when Francis Wong Hon-chung, 48, was summoned by the ICAC following the revocation of his Australian visa, he probably thought he was being called in to discuss liaison matters, the court was told. Wong denies uttering forged documents with intent to defraud on September 19, 1990. It is alleged that while employed as acting Assistant Commissioner of the CSD he gave himself a false background in industrial chemistry in order to qualify for an Australian government migration programme. In an ICAC videotaped interview, Wong agreed he had applied for the Employer Nomination Scheme through Patrick Wong, a family friend. The defendant had been offered a job as sales manager by Patrick Wong's company in Australia, but said he had not taken it up. In the video interview shown to the court, Francis Wong stressed that the question of corruption did not arise. He said: ''I received no salary, remuneration or advantage.'' Because he was not paid he did not inform the Hongkong Government, he said. He said it had been his intention to inform the Australian authorities about his full-time employment with the CSD, but Patrick Wong had dissuaded him. Francis Wong subsequently left for Australia with his wife and two children, but returned to Hongkong on the premise that there were further possibilities for promotion in the CSD. His family remained in Australia. ICAC senior investigator James Neilson, cross-examined by defence counsel Anthony Corrigan QC, agreed that Wong had not been told he had been summoned for anything other than the discussion of liaison purposes. But Mr Neilson denied that in an earlier interview Wong had been given the impression that he had already been punished sufficiently by the cancellation of his visa. Robert Ramsay, a director of an Australian-based immigration agency, admitted that a form already signed by Wong had been partly filled in at the consultancy. But he said he had assumed it would be checked by Wong afterwards. Mr Ramsay said he prepared an application for Wong under the provisions of the Employer Nomination Scheme, after he had been approached by Patrick Wong. The case continues.
