A British tax consultant found guilty earlier of using a false document to convince a court she should be allowed to leave Hong Kong while on bail in a separate case last year, was jailed for four years on Wednesday. Deborah Annells, 57, inflated the acquisition price of her company in a memorandum of understanding by changing Hong Kong dollars to US dollars, the District Court heard earlier. She submitted the document to Eastern Court, where she appeared on theft and fraud charges on April 11 last year, hoping that a magistrate would vary her bail conditions. The magistrate was misled into granting her permission to leave Hong Kong for Britain during the Easter holiday. Sentencing Annells yesterday, presiding Judge Eddie Yip Chor-man noted that she had given an impression that her business, AzureTax, was on the rise, despite her "insubstantial and declining assets". "She was every inch a flight risk," he said of Annells. Not only had the tax specialist, who was certified in Hong Kong in 1994, deceived the magistrate - she also misled her two counsel, Christopher Morley and Kevin Egan, who submitted the document on her behalf. Annells was found guilty of one count of committing an act intended to pervert the course of justice, one of attempted fraud and one of possessing a false instrument in October. The court also found Annells used a similar memorandum when attempting to rent the fifth floor of Sea Bird House in Central from landlord Winchell Wong Hung-wai. False documents were found by police who raided her home. Detective Senior Inspector Tony Tse Tsz-fung, of the Commercial Crime Bureau, told outside court how he and his colleagues raced against time to put together the case against Annells. "It was already about 4.30pm to 5pm when the bail hearing finished. It left us with two choices: either to go back to the office and write a report or find out the authenticity," he said. "But we immediately drove to Sea Bird House's office." He said he and police colleague Pang Siu-chung managed to get hold of "helpful" key witnesses that night and found that the document in question was indeed bogus. The inspector said time was tight because it was a Friday evening and had they not contacted the witnesses they could have lost two days over the weekend. Annells was to leave on the following Wednesday. Tse also said he and Pang were under immense pressure since they might have been subject to complaints and undesirable consequences had the document proved authentic. "But it's a professional judgment and we thought we knew the defendant better than the court," he said. Eight policemen, four of them drafted in from other teams, helped the investigation over a period of at least 72 hours before Annells was brought to court on Tuesday.
