According to a document made public by the "Military Human Rights Center" on April 8, the Defense Security Command made a survey of the tendency of candidates from opposition parties and presented a report on it to the then minister of National Defense between March and April, 2017 ahead of the "presidential election".

It also collected data on the tendency of media organizations and intelligence related with "national assemblymen" from opposition parties and their supporters.

The "Military Human Rights Center" said that those documents were submitted to the minister of National Defense, chief of the Security Office of Chongwadae, director of the Intelligence Service and chiefs of the staffs of the services of the armed forces.

It claimed that the prosecution knew the existence of those documents in 2018 when it investigated documents of the Defense Security Command on the enforcement of "martial law."

Calling for making an immediate investigation into the doubt about the organized and planned interference in the election by the then acting president Hwang Kyo An's regime, and probing the truth behind it, the center stressed that the Ministry of Justice should make clear why the prosecution turned a blind eye to it instead of investigating it.
