Seoul: An appellate court on Friday sentenced former Supreme Court Chief Justice Yang Sung-tae to six months in prison, suspended for one year, for abusing his power through wrongful interference in trials. The Seoul High Court handed down the sentence, reversing a lower court ruling that acquitted Yang of all 47 charges related to his alleged abuse of judiciary power. According to Philippines News Agency, Yang, who headed the top court from 2011 to 2017, was accused by prosecutors of having used trials as bargaining chips in dealings with the then administration of President Park Geun-hye. The aim was to promote his bid to establish a court of appeals. Prosecutors had demanded a seven-year prison term for the former chief justice. In the same case, former Supreme Court justices Park Byong-dae and Ko Young-han were also indicted. The lower court had acquitted both. However, the appellate court on Friday sentenced Park to a six-month prison term, suspended for a year, while upholding Ko's acquittal.
