South Korea jails former president Yoon Suk Yeol for five years over martial law crisis

Yoon was impeached, arrested and dismissed as president after his short-lived imposition of martial law in December 2024 triggered huge public protests calling for his ousting.

The most significant criminal charge against him alleges that his martial law enforcement amounted to a rebellion, and the independent counsel has requested the death sentence in the case that is to be decided in a ruling next month.

In Friday's case, the Seoul Central District Court sentenced Yoon for defying attempts to detain him, fabricating the martial law proclamation and sidestepping a legally mandated full cabinet meeting.

Yoon has maintained he did not intend to place the country under military rule for an extended period, saying his decree was only meant to inform the people about the danger of the liberal-controlled parliament obstructing his agenda.

But investigators have viewed Yoon's decree as an attempt to bolster and prolong his rule, charging him with rebellion, abuse of power and other criminal offenses.

Judge Baek Dae-hyun said in the televised ruling that imposing "a grave punishment" was necessary because Yoon has not shown remorse and has only repeated "hard-to-comprehend excuses".

The judge also restoring legal systems damaged by Yoon's action was necessary.

Yoon, who can appeal the ruling, has not immediately publicly responded to the ruling. But when the independent counsel demanded a 10-year prison term in the case, Yoon's defence team accused them of being politically driven and lacking legal grounds to demand such "an excessive" sentence.

Prison sentences in the multiple, smaller trials Yoon faces would matter if he is spared the death penalty or life imprisonment at the rebellion trial.

Park SungBae, a lawyer who specialises in criminal law, said there is little chance the court would decide Yoon should face the death penalty in the rebellion case. He said the court will likely issue a life sentence or a sentence of 30 years or more in prison.

South Korea has maintained a de facto moratorium on executions since 1997 and courts rarely hand down death sentences.

Park said the court would take into account that Yoon's decree did not cause casualties and did not last long, although Yoon hasn't shown genuine remorse for his action.
