The prosecution appeals the commutation of two people in charge of the poor levee of the Osong disaster.

The Cheongju District Prosecutor's Office appealed against the commutation of the site director and supervisor of the Mihocheon Bridge expansion project, which was cited as the cause of the Osong Underpass Disaster, in which 14 people were killed, at the appeal trial.

The prosecution explained the reason for the appeal, saying, "The second trial ruling did not recognize the causal relationship between the construction and demolition of the temporary embankment in 2022 and the flood accident among the business negligence that followed after the embankment incision in 2021 before the accident."

He also added, "Any part of the failure to recognize the use of forged evidence, such as a temporary relief construction plan, needs to be judged by the Supreme Court."

Earlier, the second trial court sentenced a field manager accused of professional manslaughter and evidence forgery to six years in prison, and the head of the supervision team sentenced him to four years, down from six years in prison.
