SEOUL, Feb 24, 2026 (BSS/AFP) - South Korea's former president Yoon Suk Yeol has filed an appeal against an insurrection conviction stemming from his 2024 
martial law declaration, his lawyers said Tuesday.

The Seoul Central District Court found Yoon guilty last week of leading an insurrection designed to "paralyse" the National Assembly, and sentenced him 
to life in prison.

Yoon initially branded the verdict "difficult to accept" but did not immediately indicate whether he would appeal.

His legal team said Tuesday they would challenge the verdict.

"We believe we have a responsibility to clearly place on record the problems with this ruling -- not only in the court's records, but also before the 
judgement of history in the future," Yoon's lawyers said in a statement.

They said they took issue with the prosecution's "excessive indictment" and would take action against "the contradictory judgement rendered... based on 
that premise, and the political context surrounding it".

Last week, presiding judge Ji Gwi-yeon said Yoon sent troops to the National Assembly building in an effort to silence political opponents who had 
frustrated his attempts to govern.

"The court finds that the intention was to paralyse the assembly for a considerable period," Ji said.

Yoon was a deeply unpopular president at the time of the martial law crisis.

His party was vastly outmuscled in parliament, which had voted to block budget measures and impeach key figures in his administration.

With support from senior military figures, Yoon dispatched troops to seize control of the assembly building and arrest critics.

The judge said that Yoon "became fixated" on his belief that the opposition 
"could effectively neutralise the president".

- Protests and panic -

Yoon appeared on late-night television on December 3, 2024, to deliver a shock address to the nation.

Pointing to vague threats of North Korean influence and dangerous "anti-state forces", he declared the suspension of civilian government and the start of 
military rule.

Martial law was lifted around six hours later, after lawmakers raced to the assembly building and voted it down.

The crisis triggered protests, sent the stock market into panic and caught key military allies such as the United States off-guard.

Yoon was ousted in April last year, and voters elected President Lee Jae Myung in a snap election in June.

Yoon apologised last week for the "hardship" caused by his martial law decree, but insisted it was a measure taken "solely for the sake of the 
nation".
