this article is all wrong, but it says a K-pop star being called up for duty as a conscript might be subject to trial by court-martial for offenses committed before he has entered the South Korean armed forces. Excerpt:
Last week, prosecutors indicted former Big Bang member Seungri, whose real name is Lee Seung-hyun, on charges of violating laws on prostitution, illegal gambling and foreign currency trading.
The state-run Military Manpower Administration announced on Tuesday that it had sent Seungri documents asking him to report for 21 months of mandatory military service, a requirement for all able-bodied men in South Korea, because prosecutors had ended their investigation.
It said in a statement that it was concerned a protracted trial in civilian courts would hamper its efforts to equally apply the military obligation on Seungri, 29. The administration said Seungri’s case would be handed over to a military court if he joined the military.
