A South Korean appeals court on April 28 raised the prison sentence of former First Lady Kim Keon Hee from 20 months to 4 years in prison, after convicting her of further charges.

On Jan. 28, Seoul Central District Court sentenced Kim to one year and eight months in prison for corruption, after finding her guilty of receiving luxury gifts, including a Chanel bag and a Graff diamond necklace, from the Unification Church, in exchange for promises of political favors.
The court initially acquitted Kim of other charges, including stock price manipulation and violations of the political funding law, citing a lack of evidence among its reasons.

Both Kim and prosecutors appealed the ruling, and on Tuesday, the Seoul High Court raised her jail term to four years after convicting her of the stock manipulation charge and of receiving another Chanel bag from the Unification Church.

South Korea’s judicial system allows prosecutors to challenge sentences and rulings—giving them the same rights as defendants to appeal—if they believe the decisions are flawed.

The former first lady's defense team has argued the prosecution's investigation was politically driven. The team of independent counsel Min Joong-ki had earlier requested a 15-year prison sentence.

Kim is the husband of former President Yoon Suk Yeol, who is facing multiple charges across eight trials connected to his brief imposition of martial law in December 2024 and related accusations.
In February, Seoul Central District Court found Yoon guilty on charges of abuse of authority and orchestrating an insurrection, and he was sentenced to life in prison.
Kim’s charges were unrelated to her husband’s trials, and investigators have said that the former first lady was not involved in Yoon’s martial law decree.

‘Damaged Public Trust’

The Seoul High Court said that, as first lady, Kim was closest to the president and had significant influence over him.

Due to her position and actions, Kim failed to meet public expectations for her integrity, instead exploiting her high-profile status.

"Kim exerted her influence as first lady and committed the bribery," the lead judge said. "She damaged public trust in government transparency and caused ​a rift in public opinion over national affairs."

The former first lady denies all charges, and her lawyers said they would appeal Seoul High Court's ruling. Both Kim and prosecutors have one week to appeal the decision at the Supreme Court, South Korea's top court.

The former first lady has been in prison since August 2025 after the court approved a warrant to have her detained, citing the chance that she might destroy evidence.

Insurrection Conviction

Yoon attempted to impose martial law on Dec. 3, 2024, but backed down after six hours, following parliament’s vote to overturn the decree.

He said he imposed the measures in order to protect the South Korean constitution because the opposition, which controlled the parliament, was sympathetic to communists and North Korea. He had told the court that it was within his powers as president to call for a state of emergency, meaning that declaring martial law could not constitute an insurrection.

Yoon faces a total of eight trials related to the martial law decree. He received his first conviction on Jan. 16 for charges including mobilizing the presidential security service to prevent authorities from detaining him. For that conviction, he received a five-year prison sentence.

On Feb. 19, Seoul Central District Court found Yoon guilty on charges of abuse of authority and orchestrating an insurrection, and he was sentenced to life in prison.

Prosecutors had sought the death penalty, though no one has been executed in South Korea since 1997, following the introduction of a moratorium on capital punishment in 1998.

Another of Yoon's trials recently closed, during which the former president faced charges of benefiting an enemy and of abuse of power.

South Korean prosecutors accuse Yoon of trying to escalate tensions with North Korea by allegedly flying drones over Pyongyang in a bid to create justification for later imposing martial law.

Prosecutors requested on April 24 a 30-year prison sentence for the conservative politician, if found guilty.

Seoul Central District Court is expected to make a ruling on the case at a later date.

Yoon and his lawyers have denied all charges he faces.
