People Power Party leader Jang Dong-hyuk and lawmaker Kim Min-seok demanded the restoration of the prosecution’s supplementary investigation authority this week [1].
The push for these changes follows allegations of police misconduct in a missing-person case in Jeju. Party leaders said the current distribution of investigative powers creates gaps in law enforcement that endanger public safety.
Jang made these comments on June 26, marking one year [1] since he assumed his role as party leader. He said the stripping of supplementary investigation powers has led to citizens suffering harm [1]. According to Jang, restoring these powers is necessary to protect the safety of the public [1].
Lawmaker Kim Min-seok focused on the need for systemic changes within the police force. Kim said the government must accelerate police reform to eliminate abuses, including the practice of hiding cases [1].
The People Power Party linked the mishandling of the Jeju case directly to the lack of prosecutorial oversight. They said that without the ability for prosecutors to conduct supplementary investigations, police errors remain unchecked, leaving critical cases unresolved.
This demand for reform comes as the party seeks to redefine the balance of power between South Korea's investigative agencies. By citing a specific failure in the Jeju case, the party aims to provide a concrete example of why the current legal framework is insufficient for protecting citizens [1].
“The stripping of supplementary investigation powers has led to citizens suffering harm.”
This move signals an effort by the People Power Party to roll back previous reforms that limited the prosecution's power in favor of the police. By framing the issue around public safety and the specific failure of the Jeju missing-person case, the party is attempting to shift the political narrative from one of prosecutorial overreach to one of police incompetence.
