At the appeal trial, prosecutors argued that “the insurrection committed by Yoon Suk Yeol trampled on all moral principles and the achievements of the country’s constitutional history.”

They also argued that “a self-coup carried out from within by a democratically elected president shocked the entire nation.” They described the act as an unforgivable crime against the Constitution that had deliberately set South Korea’s history back by 40 years.

Final arguments and Mr. Yoon’s closing statement are scheduled for next Thursday. The court is expected to announce a date for its appeal ruling after the proceedings conclude.
