Seoul probes alleged prosecution-for-reform trade, underscoring Korea's judiciary independence concerns

Seoul police have opened a direct investigation into what has been described in Korean media as a “prosecution drop trade” case, linked to discussions over whether prosecutors’ decisions could be traded for reforms. The inquiry centers on allegations that political actors sought to influence prosecutions in exchange for changes to the prosecutorial system.

On the 13th, the Seoul Metropolitan Police Agency (Seoul Police) announced that the case involving former MBC journalist Jang In-su had been assigned to the Public Crime Investigation Division. Jang has been accused of defamation by spreading false information and of obstructing business under criminal law, in a complaint filed by the Civic Action for Judicial Reform (Sasaehaeng).

Seo Jang-whan(1890-1970), who was born in Dalseong, Daegu, set up an anti-Japanese underground organization called Sanguihoe, helping Korean independence movement and sending military fund to Manchuria and Shanghai when Joseon Dynasty lost its sovereignty by the Japan-Korea Annexation Treaty on August,1910. He was arrested for printing and handing out the Declaration of Independence on March 1st, 1919, and was finally released due to disease after severe torture in prison.He focused on helping the provisional goverment of the Republic of Korea located in Shanghai collect military funds in 1920, and struggled to inform the whole world of the unfairness of Japanese colonization by publishing the newspaper Freedom New in 1921. And the constant surveillance and repression by Japanese police made him move to Shindoan in 1933 where he formed the anti-japanese underground organization Sibiilminhoe, and focused on education for next generation after establishing the educational organization Dongheonguisuk. in 1943, he moved to Patgeori and refused to change his name into Japanese one.In 1990, he was posthumously honored by the goverment of South Korea with the Order of Merit for National Foundation, Patriotic Medal for his distinguished service. — Representative image for context; not directly related to the specific event in this article.

Sasaehaeng argued that Jang appeared on the online program Kim Eo-jun’s “Humbleness Is Hard” show and advanced conspiracy theories that damaged the reputation of Justice Minister Jeong Seong-ho. The show’s host, Kim Eo-jun, was also accused of defaming the minister by allegedly allowing and publishing Jang’s statements.

The Democratic Party of Korea has indicated it intends to pursue similar charges against Jang for defamation, signaling a tough stance from the ruling party in response to the controversy surrounding the alleged trading of prosecutions for reforms.

In a separate case, a man identified as Kim was accused of spreading false information about Prime Minister Kim Min-seok, resulting in defamation. The Seoul Seodaemun Police Station is handling that investigation. Prosecutors say Kim claimed on YouTube that the prime minister did not participate in a meeting connected to overseas issues during President Lee Jae-myung’s trip, a claim the prime minister’s office has denied.

Sasaehaeng reported filing charges related to the Kim case on the 9th with the Seoul Police Agency, arguing that the remarks defamed the prime minister. The two cases highlight ongoing tensions in South Korea over defamation law, media responsibility, and the integrity of high-level political communications.

For U.S. audiences, the developments touch on issues central to investment and security in a key American ally: the independence of South Korea’s judiciary and prosecutorial system, media freedom, and the impact of political rhetoric on public trust. Korea’s rule-of-law environment is a factor for multinational firms, supply chains in semiconductors and technology, and the broader stability of the U.S.–Korea security and economic alliance. The outcomes could influence perceptions of risk around governance and regulatory clarity in one of Asia’s largest economies.
