Chapter 4: Prosecutor Han Dong-hoon: A Man Who Rose for South Korea

The traces Han Dong-hoon has left on South Korea
A prosecution philosophy free from partisanship, a person who conducted investigations like an independence movement
On the claim that Yoon Suk-yeol elevated Han Dong-hoon's career and raised him
There are claims that Yoon Suk-yeol raised Han Dong-hoon from the beginning. This narrative has come from those who envy and slander Han Dong-hoon. It is an old story, a repeated story, and thus a story that has hardened into accepted fact.
But objective records tell a different story. To be precise, they tell the opposite story.
In 2003, Criminal Division 9 of the Seoul District Prosecutor's Office. Han Dong-hoon, then two years into his career as a prosecutor, was present at a search and seizure operation regarding accounting fraud at the third-largest conglomerate. It was he who secured the key document the investigation team needed most, the so-called "report document." The group's chairman was arrested. Han Dong-hoon was only thirty years old at the time.
We must identify who directed this investigation. At that time, the chief of Criminal Division 9 was Prosecutor Yi In-gyu. He was a skilled investigator of corporate crimes who later served as chief of the Supreme Prosecutors' Office's Central Investigation Division. Under Yi In-gyu, Han Dong-hoon broke through on his first major case. Yoon Suk-yeol was merely one of several prosecutors dispatched from the Gwangju District Prosecutor's Office and assigned after this case expanded to the Supreme Prosecutors' Office's Central Investigation Division. It was not Yoon Suk-yeol who discovered and developed Han Dong-hoon, but Yi In-gyu. Even Yi In-gyu himself wrote in his memoir that Han Dong-hoon's abilities showed "exceptional logical insight and penetrating understanding of the essence of matters."
The same applies to subsequent investigations. In 2004, at the Supreme Prosecutors' Office's Central Investigation Division. A case involving the ruling party's representative illegally receiving presidential campaign funds. This investigation was led by Investigation Division Chief Ahn Dae-hee and Investigation Planning Manager Moon Hyo-nam, with Yi In-gyu joining the investigation team. Yoon Suk-yeol was also one of the dispatched prosecutors at the time. Han Dong-hoon was also a dispatched prosecutor. The two were merely teammates on the same investigation team, not in a superior-subordinate relationship. The fact that Han Dong-hoon was one of the investigators who secured testimonies about 100 billion won in political slush fund flows was only recently confirmed.
In 2006, again at the Supreme Prosecutors' Office's Central Investigation Division. After completing his studies at Columbia Law School in the United States, Han Dong-hoon returned and took charge of investigating a slush fund case involving a major domestic automobile group as a Prosecutors' Research Official. Slush funds of approximately 1.38 trillion won came to light and the group's chairman was arrested. That same year, the Lone Star foreign exchange bank sale case. In Lone Star-related investigations, it was Han Dong-hoon's investigation alone that yielded a guilty conviction. This judgment later became the defense argument by which South Korea protected 6 trillion won in national interest in the Lone Star ISDS. In these investigations, Han Dong-hoon's direct superior was the then-Chief of the Investigation Division, not Yoon Suk-yeol. Yoon Suk-yeol was in a completely different position at that time.
In 2007, the Special Investigation Division of the Busan District Prosecutor's Office. A bribery case involving the incumbent National Tax Service Commissioner. It was the first time in South Korean prosecutorial history that an arrest warrant was sought for the sitting head of tax administration while in office. The leadership of the Supreme Prosecutors' Office urged a non-arrest approach. Han Dong-hoon traveled from Busan to Seoul and met the Prosecutor General directly. He said he would stake his position. The warrant was sought, and the Tax Service Commissioner was arrested. This investigation has no connection to Yoon Suk-yeol. The chain of command was different, the department was different, and the investigation target was different. It was accomplished solely through Han Dong-hoon's own judgment and determination.
To summarize: among the major cases that brought Han Dong-hoon recognition as a prosecutor, there were none that Yoon Suk-yeol directed as his direct superior prior to the 2016 Special Prosecutor investigation. From 2003 to 2007, those who built Han Dong-hoon's investigative career were Yi In-gyu, Ahn Dae-hee, and the chiefs of each division. Yoon Suk-yeol was merely a senior prosecutor with whom he worked on the same investigation teams.
Then where is the basis for the claim that he was raised from the start?
An in-depth reporting article from Monthly Joong Ang made this point clear. At the time in 2003, Han Dong-hoon was a new prosecutor in his second year, and legal community figures testify that it would be difficult to trace the connection between the two back to that period.
In the 2016 Special Prosecutor investigation, Yoon Suk-yeol was the investigation team leader, and Han Dong-hoon was in charge of investigating the chaebol chairman. When the first arrest warrant was rejected, it was Han Dong-hoon who personally appeared in the second warrant review hearing and secured the arrest. Han Dong-hoon's investigation was at the center of praise for the Special Prosecutor achieving the best results to date. It is true that in the Moon Jae-in administration, Yoon Suk-yeol was selected as chief of the Seoul Central District Prosecutor's Office and Han Dong-hoon was assigned as Deputy Chief Prosecutor. However, even then, it was Han Dong-hoon who led the key operational work, including the investigation into the arrest of the former president and the investigation into misuse of judicial administrative authority.
To be honest, it is rather the opposite. It is more consistent with the record to say that Yoon Suk-yeol received recognition as a "star of the prosecution" thanks to the investigative abilities of capable junior prosecutors, including Han Dong-hoon. For an investigation team leader to shine, the investigators must produce results. Han Dong-hoon was a prosecutor who produced results.
Rather, the record points in the opposite direction.
In 2012, Yoon Suk-yeol investigated the National Intelligence Service's rigged comment case and then clashed directly with the Park Geun-hye government. He was demoted to a provincial post. Within the prosecution, Yoon Suk-yeol was treated as a persona non grata. No one came near him.
At that time, Han Dong-hoon was one of the few people who remained by Yoon Suk-yeol's side. When Yoon Suk-yeol came to Seoul on weekends, the two would walk Namsan in shorts. They had few overlapping interests privately and little to talk about, it is said. They simply walked side by side in silence. He was there beside a man whom no one sought out. Looking at objective records alone, it is correct to say that during his prosecution career, Han Dong-hoon actually helped Yoon Suk-yeol more.
Behind the claim that he was "raised from the start" lies a logic of ownership. The logic that since he is a person I created, he must follow my will regardless of South Korea's fate. That is not friendship between a senior and junior. It is a relationship between master and creation. Han Dong-hoon rejected that relationship, and that rejection preserved the Constitution of South Korea on the night of December 3, 2024.
There is one more point to consider.
Yoon Suk-yeol once said this about Han Dong-hoon when he was a presidential candidate. "A person who has conducted investigations like an independence movement." What did this acknowledge? It acknowledged the fact that Han Dong-hoon has conducted investigations by his own strength, by his own conviction, and while taking on his own risks. An independence movement is not something that someone carries you along to accomplish. It is something you take on yourself.
Looking at Prosecutor Han Dong-hoon's career chronologically, Yoon Suk-yeol was merely one of the companions along that long journey, not the creator of that journey itself. In prosecution history, Han Dong-hoon is the only prosecutor who arrested the chairmen of both the first- and third-ranking business conglomerates in South Korea. He is also the only prosecutor who staked his position to arrest a sitting National Tax Service Commissioner. That is not a career anyone can create by raising.
Everyone is the protagonist of their own life. Prosecutor Han Dong-hoon walked on his own two feet from the start, conducted investigations by his own judgment, and sought arrest warrants by staking his position. And at the final moment, he chose the Constitution over twenty years of friendship.
A person you have raised can be set down. A person who has risen on his own, no one can set down.
