South Korea’s top court upholds ex-president Yoon’s seven-year sentence in martial law case

South Korea’s highest court on Thursday upheld ex-president Yoon Suk-yeol’s seven year prison sentence over crimes tied to his botched 2024 martial law declaration and its chaotic aftermath.

The case covered accusations that Yoon had obstructed cabinet deliberations and used forged signatures of the prime minister in the lead-up to the 2024 declaration, as well as using presidential security agents to block his own arrest after lawmakers had nullified it.

The former president is already in detention while he appeals a separate life sentence for leading an insurrection with his martial law declaration, which he insists was motivated by public interest.

In the case brought before the Supreme Court, Yoon was accused of obstructing deliberations by convening only a select group of ministers for a meeting shortly before he declared martial law.

Other charges included allegedly creating and destroying a false martial law decree bearing forged signatures from the prime minister, ordering officials to distribute a misleading press release to foreign media, and directing an army commander to delete records from secure military phones.

Prosecutors had sought a 10-year prison sentence for Yoon.

In January, a lower court had sentenced Yoon to five years in prison after convicting him on most charges.

In April, an appeals court upheld the ruling, added a guilty verdict over the misleading press release, and raised the sentence to seven years.

Both prosecutors and Yoon’s legal team had appealed to the Supreme Court, whose rulings are final.

“All appeals are dismissed,” a Supreme Court judge said in a televised ruling, adding that the lower court’s judgment “contained no errors”.

Yoon’s legal team expressed “deep regret”, accusing the Supreme Court of concluding the case “without sufficient deliberation”.
