The Democratic United Party is set to file another complaint with the prosecutors’ office over the issues surrounding the Northern Limit Line in the West Sea just as law enforcement authorities prepare to look into charges brought earlier.

On Tuesday, DUP lawmakers Reps. Park Beom-kye and Jung Cheong-rae announced that they would file a complaint against senior presidential security secretary Chun Young-woo over his claim to have read the minutes of the 2007 inter-Korean summit between late President Roh Moo-hyun and Kim Jong-il.

Saying that Chun had violated the Act on the Management of Presidential Archives by viewing the records, Park and Chung called for “swift investigation and strict penalization.”

Under the act, records designated as presidential archives require the approval of more than two thirds of the National Assembly or a warrant from the high court that has jurisdiction before they can be viewed by those who are not Presidential Archives staff.

The development comes as the prosecutors prepare to launch the investigation into Saenuri Party Reps. Chung Moon-hun, Lee Cheol-woo and party public relations officer Park Seon-kyu over the DUP’s complaint that the three spread falsehoods damaging to Rep. Moon Jae-in’s campaign according to the Public Official Election Act.

The earlier complaint concerns Chung’s claims that he had read records of Roh dismissing the legitimacy of the NLL.

According to Chung, the comments were made during a one-on-one meeting between Roh and Kim held on the sidelines of the summit, and the contents of the meeting are included in the transcript of the conversation passed onto Seoul by North Korean authorities.

The two parties also continued the war of words over the issue despite NIS Director Won Sei-hoon’s testimony on Monday.

Speaking as a witness in the parliamentary audit of the NIS, Won said that a transcript of the conversation between Roh and Kim exists, but that records of an undisclosed meeting or information regarding the alleged meeting compiled by North Korea did not.

Won, however, left room for further friction between the ruling and opposition parties, saying that the NIS would consider allowing lawmakers to view the records if the two parties reached an agreement.

The development prompted Rep. Suh Sang-kee, who chairs the Intelligence Committee, to officially request the NIS to open the records.

“If the NIS does not accept (the request to view the records), I will achieve the goal even if it requires the use of the rights of a member of the National Assembly,” Suh said on Tuesday.

He added that he was prepared to meet all administrative, legal and political conditions the NIS or the DUP may suggest for viewing the material, saying that the NIS chief has said that viewing might be allowed on condition of nondisclosure.

For its part, the DUP continued to attack the ruling party, calling the situation a “typical case of fabrication” that aims to stir up North Korea-related issues to shore up support for the conservative presidential candidate.

“We cannot but lament this situation where national security is used as a tool of political strife that throws the nation’s fundamentals into disorder,” Rep. Jin Sung-joon of the DUP said.
