The constitutional court unanimously voted to uphold Yoon Suk Yeol's impeachment, paving the way for a snap election within 60 days.

South Korea's ousted leader Yoon Suk Yeol argued that his brief martial law declaration late last year was "not a coup d’etat" as he appeared in court on Monday for the start of a criminal trial over charges that he led an insurrection.

Yoon Suk Yeol's legal saga is far from over. Ten days after he was ousted from office over his martial law declaration, the former conservative South Korean president appeared for the first time at his criminal trial Monday on high-stakes rebellion charges.
