Suspended President Yoon Suk Yeol attended the third hearing of his impeachment trial at the Constitutional Court on Tuesday, where it was anticipated that he would try to explain his controversial declaration of martial law on Dec. 3.

It marked the first time in South Korea for an impeached president to appear in person at a Constitutional Court trial.

Yoon, who, along with being on trial for impeachment, is under criminal investigation on charges of leading an insurrection and committing abuse of power, was suspended from his duties following his Dec. 14 impeachment in parliament.

Despite being under detention, the 64-year-old appeared in a suit and tie, rather than prison garb.
