A High Court judge has rejected a bid to have immigration charges against a millionaire businessman thrown out.
And in a further boost to the Crown case against William Yan - also known as Yang Liu and Yong Ming Yan - Justice Timothy Brewer has ruled that evidence from an Australian investigator is admissible against him.
Yan is on trial in the High Court at Auckland after pleading not guilty to four charges relating to false declarations on immigration papers in 2001 and 2002 and one of using false written statements to get citizenship.
The wealthy businessman was granted New Zealand citizenship in August 2008 under the name Yang Liu, despite advice from Department of Internal Affairs officials that he did not meet the good character test. Just days later he changed his name to William Yan, the name he is being prosecuted under.
The department's case officer, Johannes Gambo, told the court Yan boasted that he had politician friends who would ensure he was granted citizenship.
