South Korea Court Upholds Defamation Conviction Linked to Lee Jae-myung Campaign
A South Korean president has publicly commented on the final sentencing in a high-profile defamation case that tied a political opponent to organized crime. The case centers on Jang Young-ha, a district party leader for the People Power Party in Seongnam, a city in Gyeonggi Province near Seoul, who alleged during the 2022 presidential race that President Lee Jae-myung was connected to a violent criminal group.
According to court records, Jang accused the president of receiving about 2 billion won in exchange for business favors while serving as Seongnam mayor, based on statements from Park Cheol-min, a member of a violent group described in the filing as the “International Mafia.” Jang acted as Park’s lawyer in the case. Prosecutors had initially declined to indict Jang, but a related civil or political-advocacy action led to charges being filed in 2023.

In the trial sequence, the first court ruling cleared Jang of the charges. However, the second trial found that he had disseminated the allegations knowingly, even while aware they might be false, and sentenced him to one year in prison with a two-year probation period. The Supreme Court later confirmed that judgment, making the verdict final.
President Lee Jae-myung reacted on social media to share the news of the ruling’s finalization and to condemn what he described as irresponsible media coverage. He criticized coverage that spread unverified claims about him during the campaign and noted that there was no apology or correction from those outlets. He also emphasized that many people still believe the baseless allegation, and urged a media environment free of fake news.
Lee Gun-tae, a Democratic Party lawmaker, thanked those who supported the case and helped publicize the verdict. The president’s post concluded with a call for truth and justice to prevail in public discourse, contrasting it with what he described as misinformation.

The case illustrates the tension between political speech and defamation laws in Korea, particularly during elections. Jang’s conviction reflects the judicial stance that disseminating false allegations about a public figure can be a criminal act, even in a highly charged political climate. The proceedings also spotlight the role of social media in propagating or challenging such claims, a dynamic with clear resonance beyond Korea’s borders.
For international readers, the episode matters because it touches on broader issues of misinformation, media accountability, and the rules governing political speech in democracies. In the United States, debates over fake news, fact-checking, and the consequences of unfounded accusations during campaigns echo Korea’s experience here, with potential implications for trust in institutions, cross-border diplomacy, and the investment climate tied to stable governance in one of Asia’s largest economies.
