Former Supreme Court Chief Justice Yang Sung-tae is set to be grilled over his alleged role in a power abuse scandal involving former top court officials.
The Seoul Central District Prosecutors' Office asked him to come for an interrogation on January 11th.
The 71-year-old former judge has been accused of using trials as a bargaining chip in his dealings with the Park Geun-hye administration to achieve his long-envisioned plan of establishing a separate court of appeals.
Last June, Yang flatly denied involvement in the scandal, claiming that there was no interference in trials and that they weren't used for any political bargaining.
If Yang complies with the prosecutors' latest request, he will be the first former head of the Supreme Court to face questioning by the prosecution as a suspect.
