In the letters the organization recalled that a lot of people and experts still remain skeptical about the "results of investigation" into the case, but the authorities do not positively respond to it.

Worse still, the "government" tried hard to impose additional sanctions upon the DPRK through the UN Security Council and, not content with this, it is suppressing civic and public organizations demanding serious reinvestigation into the case, labeling them "organizations benefiting the enemy", the organization said, adding:

In order to solve this problem, the "National Assembly" should push forward "inspection of the national administration" for probing the truth behind the case irrespective of party affiliation.

Through the above-said inspection the NA should verify the "results of investigation" into the case to probe whether the "government's" assertion is true or not and clarify who is accountable for it.

Meanwhile, the Solidarity for Progress of south Korea, the Citizen's Solidarity for Democratic Society and the Society for Human Rights Movement made public a joint statement on the same day in denunciation of the puppet group of traitors' suppression of the students demanding a probe into the truth behind the case.
