3-year prison term finalized for ex-PSS chief for obstructing Yoon's arrest

Former Presidential Security Service chief Park received a three-year prison term for obstructing investigators who tried to execute a warrant against former President Yoon Suk Yeol. The sentence became legally final after neither Park nor prosecutors appealed the Seoul High Court ruling by Wednesday’s deadline.

The high court had reduced Park’s four-year lower-court sentence. It found that he had not actively participated in physical confrontations with investigators. The court also viewed his resignation on Jan. 7, 2025, as showing accountability for the confusion and conflict that followed.

The result closes Park’s appeal process in this case. His finalized sentence is shorter than the original term, but he remains convicted of obstructing the warrant’s execution. The same ruling also finalized prison terms for two other former PSS officials, while former deputy chief Kim Seong-hoon continued his case by appealing to the Supreme Court.

The Presidential Security Service, or PSS, is South Korea’s government security agency for protecting the president. Its work includes securing the president, the presidential residence, and, as the article notes, the president’s family. Its central purpose is to prevent threats and maintain safe presidential operations.

That protective role placed PSS officials at the center of the January 2025 confrontation. Investigators went to the presidential residence to execute a warrant to detain former President Yoon Suk Yeol. Former PSS officials were later indicted for obstructing that effort, leading to prison sentences for several of them.

The case shows that presidential protection can involve difficult duties during legal proceedings. Security officials may guard a president, but their actions can still be examined by courts. Here, Park, Lee Kwang-woo, and Kim Shin received finalized terms, while former deputy chief Kim Seong-hoon appealed his five-year sentence.

Investigators went to former President Yoon Suk Yeol’s presidential residence in January 2025 to execute a warrant to detain him. Their attempt was blocked by Park and other former Presidential Security Service officials, who were later indicted over the obstruction.

The warrant had been issued in connection with Yoon’s imposition of martial law. The article does not provide further details about the underlying allegations or the warrant’s exact legal basis. It does establish that investigators were attempting to carry out the warrant at the residence, rather than simply conduct an informal interview.

The confrontation led to criminal cases against former PSS officials. Park’s sentence was ultimately fixed at three years, while Lee Kwang-woo received two years and Kim Shin received a one-year sentence suspended for two years. Former deputy chief Kim Seong-hoon appealed his five-year sentence to the Supreme Court.

Prison terms were finalized for three former Presidential Security Service officials. They were former PSS chief Park, former bodyguard division chief Lee Kwang-woo, and former PSS official Kim Shin. Their sentences differed in length and in whether imprisonment was immediately suspended.

Park received three years in prison. Lee received two years. Kim received one year, suspended for two years. The appellate court had reduced Park’s sentence from four years, while the article reports the other two terms as finalized after the appeal period ended.

The officials’ sentences reflect different outcomes within the same obstruction case. Park and Lee face finalized prison terms, while Kim’s one-year term is suspended for two years. Former deputy chief Kim Seong-hoon is not included in this final group because he appealed his five-year sentence to the Supreme Court.

When neither the defendant nor prosecutors appeal a high-court ruling by the legal deadline, the ruling becomes final. In this case, Park and prosecutors each had seven days to appeal the Seoul High Court’s decision to the Supreme Court. Neither side filed an appeal by Wednesday.

The deadline mattered because an appeal is the route for seeking review by the Supreme Court. Once that period ended without an appeal, Park’s reduced three-year sentence was finalized. The same process finalized the terms for Lee Kwang-woo and Kim Shin, according to the article.

This differs from Kim Seong-hoon’s position. He appealed his five-year sentence, so his case remains before the Supreme Court rather than ending with the high-court ruling. The article does not state when the Supreme Court will decide his appeal or what result it may reach.

Once a prison sentence becomes final, the convicted person no longer has an ordinary appeal pending in that case. Park’s three-year term, Lee Kwang-woo’s two-year term, and Kim Shin’s one-year sentence suspended for two years were all finalized, according to the article.

The difference is especially clear with Kim Shin. His one-year prison term is suspended for two years, unlike the immediately imposed prison terms reported for Park and Lee. The article does not explain additional enforcement details, such as custody arrangements or conditions attached to the suspension.

Kim Seong-hoon remains in a different legal position. The former PSS deputy chief appealed his five-year sentence to the Supreme Court. His high-court sentence is therefore still under review, and the article does not state the Supreme Court’s eventual decision or timetable.

A judicial warrant represents legal authority for investigators to take a specified action. Government security agencies may protect a president, but that protective role does not automatically cancel a court-authorized investigation. Obeying the warrant helps preserve the rule that public officials operate within the law.

The article gives a concrete example. Investigators went to the presidential residence in January 2025 to execute a warrant to detain Yoon over his imposition of martial law. Park and other former PSS officials were indicted after obstructing the attempt. Courts later imposed prison terms on several officials.

The finalized sentences show the legal consequence of resisting the process. Park received three years, Lee Kwang-woo two years, and Kim Shin one year suspended for two years. Kim Seong-hoon appealed his five-year sentence. The article does not describe broader policy changes, but the case underlines that security duties do not erase judicial authority.
