SEOUL, Jan. 11 (Yonhap) -- Former Supreme Court Chief Justice Yang Sung-tae was set to undergo prosecution questioning Friday over allegations that he used trials as political leverage to lobby the previous government to achieve his personal ambitions.
His presence is expected at the Seoul Central District Prosecutors' Office by 9:30 a.m. Prosecutors summoned him last Friday, and Yang has said he would comply with the request.
It makes Yang the first former head of South Korea's Supreme Court to face a prosecution interrogation as a criminal suspect. The former veteran justice led the top court from 2011 to September 2017, when he retired.
Yang will issue a formal statement near the Supreme Court before he goes to the prosecution.
Yang, 71, is suspected of using or seeking to use trials as bargaining chips in its dealing with the then Park Geun-hye government to get her approval for establishing a separate court of appeals, his long-envisioned plan.
He allegedly instructed his officials at the National Court Administration (NCA), the top court's governing body, to devise ways to interfere in trials whose rulings potentially held high political significance for Park.
