South Korean President Yoon Suk Yeol attended on Tuesday a Constitutional Court hearing of his impeachment trial where the detained leader may get a chance to argue his case or answer questions over his short-lived bid to impose martial law.

South Korea’s impeached president has denied that he ordered the military to drag lawmakers out of the National Assembly to prevent them from voting to reject his martial law decree last month, as he appeared for the first time before the Constitutional Court that will determine his fate.

South Korean President Yoon Suk Yeol denied wrongdoing as he branded himself as a firm believer in democracy in his first appearance at an impeachment trial looking into his shocking and brief imposition of martial law last month.
