The prosecution “indicted former President Yoon Suk Yeol on charges including abuse of power and obstruction of special official duties”, prosecutor Park Ji-young told reporters.
Park said Yoon also did not follow the required procedure to declare martial law, including holding a meeting with all Cabinet members of the Government.
Yoon was also charged with “drafting and discarding a false document” that stated the Prime Minister and Defence Minister had endorsed martial law.
Yoon has refused to attend questioning since he was detained, but appeared in court on Friday at a hearing to argue for his warrant to be cancelled.
The ex-President’s legal team told reporters that Yoon defended himself for over 30 minutes, and mentioned his “limited physical mobility and the challenges he was facing”.
The court denied the request.
Yoon is being held in solitary in a cell which has a fan but no air-conditioning, as a heatwave grips South Korea.
