SEOUL, Ruling party lawmakers said Tuesday they will push for a parliamentary probe into allegations that the top court under ex-Chief Justice Yang Sung-tae used trials as bargaining chips in its dealings with the presidential office.

The Supreme Court is alleged to have sought to use politically sensitive trials in persuading senior presidential aides to then-conservative President Park Geun-hye to support Yang's bid to establish a court of appeals.

Democratic Party (DP) lawmakers sitting on the judiciary committee delivered their resolve to the party's leadership and raised the need to find the truth in the power abuse case.

"We think that the National Assembly should look into the top court's power abuse scandal and structural problems facing the judiciary circle, which is not cooperative in prosecutors' investigation," they said.

The scandal has stirred up a war of nerves between the judiciary and prosecution. Prosecutors have requested search warrants of key premises and residences of those implicated in the scandal, but these were turned down by courts.

"If a parliamentary probe reveals any wrongdoings, we will push for impeaching justices involved in the case," DP lawmakers said.

Hong Young-pyo, the floor leader of the DP, said that he will first discuss the issue at the party level and later seek consultation with opposition parties.
