South Korea’s impeached President Yoon Suk Yeol appeared in court again Tuesday as hearings continued to determine whether he will be officially removed from office. Yoon, who has been arrested and suspended from his duties after declaring martial law, remains in detention while facing both impeachment proceedings and a separate criminal trial.

The former prosecutor sparked a political crisis on December 3 when he imposed martial law, suspending civilian rule and deploying soldiers to parliament. His decree lasted only six hours before an opposition-led parliament overturned it, later voting to impeach him.

In mid-January, Yoon was arrested in a dawn raid and charged with insurrection, making him the first sitting South Korean president to be detained. He is now awaiting the Constitutional Court’s decision on whether to uphold his impeachment. If upheld, a new presidential election must be held within 60 days.

On Tuesday, Yoon was transported to the court in a convoy of black SUVs for a hearing scheduled at 2:00 p.m. (0500 GMT).

At previous hearings, Yoon denied allegations that he ordered military commanders to forcibly remove lawmakers from parliament to prevent them from overturning his decree. However, opposition MPs and key witnesses have contradicted his claims.

During Tuesday’s session, two former military commanders and an ex-intelligence official testified. Hong Jang-won, a former deputy director of the National Intelligence Service, told lawmakers that he had been ordered to arrest politicians—directly disputing Yoon’s denials.

Prosecutors have labeled the 64-year-old president the “ringleader of the insurrection.” If convicted, he faces severe penalties, including possible jail time or even the death penalty, as insurrection is not covered by presidential immunity.
