Former South Korean President Yoon Suk Yeol missed his insurrection trial for the sixth consecutive time on Thursday, prompting the Seoul Central District Court to continue proceedings in his absence.

Yoon, who has been in detention since his second arrest on July 10, has consistently refused to attend hearings, citing health issues. The court noted that prison authorities informed them it was difficult to forcibly bring him in. Under South Korea’s Criminal Procedure Code, trials can move forward if a defendant refuses to appear without valid reasons and enforcement is deemed unfeasible.

The former president faces charges of leading an insurrection and abusing power by briefly imposing martial law last December. Insurrection carries a maximum penalty of life imprisonment or even the death sentence, Yonhap reported. Thursday’s session included testimony from two military officials linked to the martial law plan.

Meanwhile, the court also held a hearing on a warrant request against former Prime Minister Han Duck-soo over his alleged involvement in the failed martial law declaration. Han faces accusations of abetting Yoon, falsifying and destroying documents, and perjury. If approved, he will become the third Cabinet member of Yoon’s administration arrested in connection with the case, following ex-Defense Minister Kim Yong-hyun and ex-Interior Minister Lee Sang-min.

Han is alleged to have pushed for a Cabinet meeting before the decree and later destroyed a revised proclamation meant to strengthen its legitimacy. He also allegedly lied under oath to both the National Assembly and the Constitutional Court.
