The Anti-Corruption and Civil Rights Commission (ACRC) of South Korea announced on the 5th that it has chosen not to prosecute prosecutor Lim Eun-jung, the head of the Seoul Eastern District Prosecutors' Office, and former chief inspector Han Dong-soo over allegations of leaking official secrets. These allegations stem from an incident in March 2021, when Lim, who was then a policy researcher at the Supreme Prosecutors' Office, posted information related to the investigation into former Prime Minister Han Myeong-sook on her Facebook page. This information was deemed confidential and its leaking raised concerns about the integrity of the investigation concerning allegations of witness tampering involving bribes by a former construction company head.

In March 2021, the Supreme Prosecutors' Office, under instructions from then-Minister of Justice Choo Mi-ae, was investigating the claims that former Prime Minister Han had been implicated in a scheme to influence witness testimonies in favor of the defense. On the eve of a disposition that found no grounds for indictment regarding these claims, Lim's Facebook post accused the Prosecutor General Yoon Seok-youl of attempting to downplay the seriousness of the investigation by refusing to proceed with these charges. The post highlighted internal conflicts within the prosecution regarding how the case was handled.

Ultimately, the ACRC determined that while Lim's actions did bring the investigation's integrity into question, they did not rise to the level of causing significant damage to the investigation's fairness or credibility, especially considering the contentious circumstances surrounding the case proceedings. The decision not to charge Lim has raised questions about transparency and accountability within the South Korean prosecutorial system, given the high-profile nature of the case and the implications it has for public trust in legal institutions.
