A South Korean appeals court reduced the sentence of former prime minister Han Duck-soo on Thursday by eight years for crimes relating to ex-president Yoon Suk-yeol's martial law declaration.

Yoon's decree in December 2024 briefly suspended civilian rule and plunged South Korea into chaos, but only lasted around six hours as opposition lawmakers moved quickly to overturn it in a vote.

A lower court had sentenced Han in January to a heavier-than-expected jail term of 23 years for engaging in the declaration.

An appeals court in the capital Seoul cut that by eight years on Thursday, with the presiding judge announcing: "We sentence the defendant to 15 years in prison."

The court still maintained most of Han's convictions, but lessened the penalties after taking into account his "more than 50 years as a public official prior to the martial law declaration".

"The records also make it difficult to find evidence showing that the defendant participated more actively in the insurrection, such as by conspiring in advance or systematically leading the operation," the judge said.

However, he said Han had "abandoned the grave responsibilities arising from the authority and position entrusted to him and instead sided with those participating in the acts of insurrection".

Han, wearing a white shirt and a dark suit with no tie, listened to the verdict without showing much emotion.
