South Korea Supreme Court Upholds Suspended Sentence for Jang Yeong-ha in Defamation Case
The South Korean Supreme Court confirmed the previous ruling against Jang Yeong-ha, a local party official for the People Power Party in Seongnam’s Sujeong District, on charges of spreading false information about a public figure. The courtpunished him with one year in prison, suspended for two years, in connection with claims about President Lee Jae-myung made under the Public Official Election Act.
The charges centered on a 2021 allegation that Lee Jae-myung, then mayor of Seongnam, received about 2 billion won in exchange for business favors to the so‑called International Mafia, a claim Jang cited as based on statements from Park Cheol-min, a member of that violent organization.

The case timeline saw the prosecutors initially not indicting Jang. The Democratic Party sought a retrial, which the court accepted, and the case was brought back to trial in May 2023.
The ruling was reported the day prior to the president’s social media post, which echoed a post by Democratic Party lawmaker Lee Geon-tae related to the case. The message emphasized a desire for truth and justice to prevail free of fake news.
President Lee Jae-myung subsequently criticized coverage that he said reported unverified claims without seeking corrections, arguing that some observers still regard him as connected to organized crime. He asserted that irresponsible reporting is a danger greater than weapons.

The case highlights tensions over defamation, false statements, and media accountability in South Korea’s political landscape. For U.S. readers, it underscores how South Korea enforces election-related misinformation rules and how media coverage can affect political dynamics in a key U.S. ally.
Beyond domestic politics, the episode matters for the U.S. because South Korea’s stability, its rule-of-law standards, and the reliability of its public institutions influence the U.S.-led security alliance, technology supply chains, and regional markets. How Seoul handles such disputes can shape investor confidence and policy coordination with Washington.
