South Korea’s Constitutional Court removed impeached President Yoon Suk Yeol from office on Friday, ending his tumultuous presidency and setting up an election to find a new leader, four months after he threw South Korean politics into turmoil with an ill-fated declaration of martial law, Associated Press reported.

The unanimous verdict capped a dramatic fall for Yoon, a former star prosecutor who went from political novice to president in 2022, just a year after he entered politics. 

In a nationally televised verdict, the court’s acting chief Moon Hyung-bae said the eight-member bench upheld Yoon’s impeachment because his martial law decree seriously violated the constitution and other laws.

“The defendant not only declared martial law, but also violated the constitution and laws by mobilizing military and police forces to obstruct the exercise of legislative authority,” Moon said, “Ultimately, the declaration of martial law in this case violated the substantive requirements for emergency martial law.”
