A South Korean court has sentenced former president Yoon Suk Yeol to five years in prison, issuing the first verdict in a series of criminal trials linked to his controversial decision to impose martial law in late 2024.

The ruling, delivered on Friday by the Seoul Central District Court, marks the opening judgment in eight separate trials Yoon faces over allegations tied to the short-lived emergency decree and related actions during his time in office.

Judges found Yoon guilty on several counts, including defying authorities who attempted to detain him following the martial law declaration. The court did not rule on the most serious allegation that the former president led a rebellion by enforcing martial law, a charge that could carry the death penalty if proven in later proceedings.

Yoon announced the imposition of martial law in a televised address in December 2024, a move that stunned the country and triggered widespread protests. Demonstrators accused him of abusing executive authority and undermining democratic institutions. Within weeks, South Korea’s parliament moved to impeach Yoon, and he was later arrested and formally removed from office.

Prosecutors argue the emergency decree was not a temporary security measure but an attempt to consolidate power and bypass a hostile legislature. Investigators have charged Yoon with rebellion, abuse of power, and several other criminal offenses connected to the episode.

Yoon’s defense team has rejected those accusations, saying the move was intended only to alert the public to what he described as obstruction by an opposition-controlled parliament. His lawyers have repeatedly accused prosecutors and independent counsel of political bias and of seeking excessive punishment without proper legal grounds.

Yoon has not publicly responded to Friday’s verdict. Earlier, when prosecutors sought a ten-year prison sentence in related cases, his legal team dismissed the demand as unjustified.

Further hearings are expected in the coming months, with the rebellion charge likely to be the most consequential. Analysts say the outcome of the remaining trials could shape South Korea’s political and legal future for years to come.
