South Korea's special counsel team is questioning former Prosecutor General Shim Woo-jung over his alleged involvement in ex-President Yoon Suk Yeol's short-lived martial law declaration in December 2024. Investigators suspect Shim played a key role by reviewing the deployment of prosecutors to a joint martial law command headquarters on the night Yoon declared martial law, and that he received instructions to do so via phone calls with the then-justice minister. The questioning follows Monday's sentencing of former Justice Minister Park Sung-jae to 25 years in prison for his part in the incident, which has triggered sweeping legal proceedings against senior officials across South Korea's government and security apparatus.
