Former South Korean President Yoon Suk Yeol was absent from his insurrection trial for the 14th consecutive session on Monday, prompting the Seoul Central District Court to continue proceedings in his absence.

Court officials said the detention center holding Yoon had informed them that it was “difficult to bring him in by force.” The bench, however, cautioned that Yoon could face disadvantages for repeatedly skipping hearings, urging his legal team to persuade him to attend in person.

Yoon’s lawyers cited his poor health and multiple ongoing investigations as reasons for his continued absence. The former president is facing charges of leading an insurrection and abusing power after allegedly attempting to impose martial law in December during his tenure.

He has been under arrest since July, marking his second detention related to the same case. A separate trial concerning the martial law attempt began last month, which Yoon attended briefly as legally required to initiate the proceedings.

In a related development, a special counsel team investigating Yoon’s alleged interference in a 2023 Marine’s death probe announced plans to summon him for questioning on October 23. The team, led by Lee Myeong-hyeon, alleges that Yoon’s administration tried to overturn the findings of a military investigation into the death of Cpl. Chae Su-geun, who died during a flood rescue mission.

This would mark the first direct questioning of Yoon by the special counsel, who insists his appearance is “absolutely necessary.”

Yoon’s continued non-cooperation in both trials and investigations underscores the deepening political and legal crisis surrounding the former leader.
