JAILED Australian-Chinese businessman James Peng Jiandong was convicted on an amendment to China's company law made more than a year after his arrest, the Sunday Morning Post can reveal. Papers released by the Shenzhen People's Intermediate Court state that Peng was sentenced according to an amendment by the National People's Congress Standing Committee passed on February 28 this year. This was 16 months after mainland-born Peng, 35, was abducted in Macau and dumped at the border where he was detained and later charged. It is understood Peng's lawyers used the discrepancy as the basis for an appeal against conviction lodged with the Guangdong Higher People's Court last week. The verdict said Peng was found guilty of 'possession' of 290,000 yuan (HK$269,410) and embezzling $800,000 in 1992 and 1989 but did not mention corruption - one of the two charges in his original indictment last October. There was no indication from the verdict whether the corruption charge had been dropped or Peng had been acquitted of the offence. He was jailed for 15 years last month on the possession charge, with another three years for embezzlement. It was unclear if the Standing Committee's decision had ex post facto effect but Don Lewis of the Hong Kong University said it was unusual for Shenzhen to convict someone on such a legal basis.
