Ukraine's Tymoshenko trial postponed again till September KIEV, Aug. 16 (Xinhua) -- A Ukrainian court Friday postponed the hearing of a case against jailed former Prime Minister and opposition leader Yulia Tymoshenko till Sept. The presiding judge Kostyantin Sadovsky adjourned the hearing for the 21st time due to the absence of Tymoshenko, who was charged with evading taxes while heading an energy company in the 1990s. Tymoshenko was due in court in the eastern city of Kharkiv, but refused to show up again because of her poor health. The former Prime Minister has constantly said this case was falsified and demanded the court to close it in her absence. Tymoshenko, who now is receiving medical treatment in Kharkov hospital, has been charged with embezzling an estimated 405 million U.S. dollars and evading tax worth more than 87,000 dollars. She is serving a seven-year prison sentence on charges of abusing powers as prime minister in negotiating an energy deal with Russia.
