South Korea’s Constitutional Court struck down the impeachment of the country’s prime minister Han Duck-soo and restored his powers on Monday, the latest twist in a political saga that started when the President declared martial law last year.

The accusation comes out of an investigation into the Presidential Security Services prevented prosecutors from arresting the President of South Korea.

The Constitutional Court reinstated Han Duck-soo as acting President, as a ruling on President Yoon Suk-yeol’s impeachment is still to come.
