A MILLIONAIRESS who used a forged will to try to swindle relatives out of a share in her mother's $33 million estate had her jail term cut yesterday because of her 'extreme eccentricity'. The Court of Appeal reduced the sentence of 21/2 years given to Leung May-chun, 49, to 18 months. But Leung failed to get the conviction quashed after suggesting her mother had intentionally disguised the signature to make it look fake. The court dismissed the claim as 'fantastic', but agreed the sentence was too harsh. Leung was found guilty of using a forged will after a handwriting expert said one of the signatures had been traced and the other copied. When Leung Suet-fun died in 1992, the family expected the estate to be split between her two daughters and her late son's three children. But a few months later Leung produced a Chinese will showing the entire inheritance had been left to her. Her sister Leung Mei-chow, 42, and sister-in-law, Yeung Mei-chung, 31, claimed it was a fake. Leung May-chun admitted writing the text of the will, but told the District Court her mother had signed the document. Judge Lugar-Mawson jailed Leung last December after finding her guilty of using a false instrument. Yesterday her lawyer, Martin Lee QC, said the judge had failed to consider the possibility the signatures were genuine but had been meant to look like fakes. He suggested Leung's mother had 'disguised' her handwriting on purpose so the will would be contested after her death. Mr Lee said Leung Suet-fun may have agreed to sign the document to get 'a nagging daughter off her back'. But at the same time she deliberately made the signatures appear forged so her other daughter would challenge the will after her death and not lose her rightful share. Mr Lee said: 'She was achieving the dual purpose of not displeasing the eldest daughter while she was alive and not having to disinherit the younger children when she was gone.' He also claimed Judge Lugar-Mawson had been wrong to say Leung had 'chosen to lead an eccentric life' in passing sentence. Mr Lee said the jail term was 'excessive' because psychiatric reports showed she could not control her eccentricity. The court agreed the judge should have taken her mental problems into consideration. Mr Justice Mortimer said: 'She is undoubtedly extremely eccentric. Although the psychiatric reports do not suggest the applicant is suffering from any identifiable mental illness, she does suffer from a serious mental eccentricity. 'We think this is not a case of a person who has chosen to lead an eccentric life. 'She leads an eccentric life because of her mental state which is not within her control.'
