Attending the trial as observers were citizens from different walks of life.

The trial examined the case of Otto Frederick Warmbier, accused of violation of Article 60 of the DPRK Criminal Code (State Subversion Charge). A written indictment confirming his crimes was submitted and there were inquiries into the facts of the case.

In the course of the inquiry, the accused confessed to the serious offense against the DPRK he had committed, pursuant to the U.S. government's hostile policy toward it, in a bid to impair the unity of its people after entering it as a tourist.

The court sentenced him to fifteen years of hard labor.
