South Korean prosecutors sought warrants Monday to arrest two former top court justices over allegations that they were involved in a judiciary power abuse scandal believed to implicate a former Supreme Court chief justice.

The Seoul Central District Prosecutors' Office requested writs against Park Byong-dae and Ko Young-han who were interrogated by prosecutors last month, according to local media reports.

It was the first time in the country's history that arrest warrants were sought against former top court judges. The decision on whether to arrest them was forecast to be made Wednesday.

Park and Ko faced multiple criminal charges, including abuse of power and obstruction of justice.

Park, 61, served as chief of the top court's administrative affairs body for two years through February 2016. He was accused of having been engaged in the so-called "trial dealings," in which the Supreme Court ruled in the politically and diplomatically sensitive trials in favor of the policy directions of the impeached President Park Geun-hye.

In return for it, then Supreme Court Chief Justice Yang Sung-tae allegedly sought to win Park Geun-hye's approval for the establishment of a separate court of appeals, known to have been a long dream of Yang.

Ko, 63, who succeeded Park as the chief of the Supreme Court's administrative body from February 2016 to May 2017, was also charged with abusing his judiciary power to intervene in the rulings by lower courts.
