Wrapping up its investigation into the absence of a 2007 inter-Korean summit transcript at the National Archives on Friday, the prosecution claimed then-President Roh Moo-hyun ordered his aides not to deliver it to the government office. It said he told them to delete all related files from the presidential office’s computer system.

The prosecution said Roh ordered his aides to make a copy of the transcript of his talks with North Korean leader Kim Jong-il, classify it as top secret and keep it at the National Intelligence Service, which had been keeping a recorded Roh-Kim dialogue file. It also said he ordered the draft transcript and the final version, kept in computer files at the presidential office, to be scrapped.

The law enforcement agency indicted Roh’s senior secretary for policy on reunification, diplomacy and security and one of his lower secretaries for scrapping the files. Though taken on an order from Roh, the prosecution said, their action constituted a serious offense.

But the opposition Democratic Party and those who were close to Roh denied the prosecution’s charges, insisting that Roh had no reason to prevent a transcript copy from being delivered to the National Archives when he had sent one copy to the National Intelligence Service. They claimed it was not delivered by mistake. They went so far as to claim that the prosecution tailored the outcome of the investigation into its preset scenario for political purposes.

The four-month investigation into the case was prompted by the ruling Saenuri Party’s claim that Roh offered to Kim to give up the Northern Limit Line, the de facto border in the West Sea. The ruling party also implied that Roh’s aides revised the draft transcript into a final version because the late president had something to hide.

Shortly after it launched an investigation, the prosecution found that the transcript was missing from the National Archives. Now it directed its attention to its mysterious absence as well.

The prosecution found no significant difference between the recovered draft transcript and the revised version. Moreover, it found it was not Roh but Kim that proposed South and North Korea give up the NLL in favor of a maritime “peace zone” on the West Sea. Roh was quoted as offering to heal “(scars left by) the NLL.”

With the investigation having left more questions than answers, however, the prosecution will undoubtedly have a fierce battle with the defendants when the trial begins. But with Roh dead, not many of the questions are likely to be answered.
