Judge Caird pulled out of the Nattrass trial in July last year after the prosecution raised fears he might be biased because of his experiences with the New Zealand immigration authorities. But the judge was ordered back on the case when Nattrass challenged his decision in the High Court. The bid by the Crown to have the judge removed came after he said a potential prosecution witness, Dorothy Smith, had made a racist remark about his Chinese wife. This was 13 years before when the judge, a New Zealander, was making inquiries with Ms Smith at the New Zealand Consulate about residency for his then fiancee. Ms Smith allegedly said: 'I suppose you found her in Wan Chai.' Judge Caird replied: 'She does come from Wan Chai but not from a brothel.' A New Zealand government official was said to have told a defence witness seven years ago: 'There are too many bloody Chinese coming to New Zealand.' In June, Judge Caird said in court: 'My wife is one of those 'bloody Chinese'.' The bitter feud between immigration consultant Nattrass and the New Zealand authorities dates back six years. Nattrass set up a firm in 1987 to help people emigrate to New Zealand. He soon complained applications were delayed because of incompetence among officials, and launched a media campaign there in 1990 to coincide with a visit by the Queen. In March that year New Zealand officials claimed applications had been rejected because of false job offers and bogus addresses. Nattrass denied this and called for an inquiry by New Zealand's chief ombudsman. He later successfully sued one senior immigration official for defamation and issued private summonses accusing another of possessing a forged letter.
