Why did a Seoul court recognize a U.S. prison sentence for Korean military-service exemption?

The court said the Military Service Act does not require the prison sentence to have been imposed or served in Korea. It found that excluding inmates from active duty to protect military discipline and the quality of the armed forces applies equally to people imprisoned overseas.

What condition did the Seoul court place on overseas prison sentences counting toward military exemption?

An overseas prison sentence qualifies only when the conduct underlying the conviction would also constitute a crime under Korean law. The court applied that condition because unrestricted recognition of foreign sentences could create a loophole for avoiding military service.

What military-service status applies to people sentenced to 18 months or more in prison in South Korea?

They are placed in wartime labor service, which exempts them from peacetime military duty and allows them to be called up for labor support only if war occurs. In this case, the man had instead been classified as eligible for alternative service as a social service agent.

A Korean-born man who spent 14 years in a U.S. prison for armed robbery does not have to serve in the Korean military, a Seoul court has ruled, extending an exemption for convicted inmates to those who have served their jail sentences overseas.

The ruling rejects the Military Manpower Administration's position that only inmates transferred to Korea to complete their sentences qualify for exemption. The court did, however, attach a condition meant to keep the exemption from becoming a loophole for draft evasion.

Under the Military Service Act, anyone sentenced to 18 months or more in prison is placed in wartime labor service, a category that exempts a person from peacetime duty and calls him up only for labor support in the event of war.

The man, whose name was withheld, moved to the U.S. with his family and later became a permanent resident there. He was convicted of robbery and aggravated assault in 2010 and was deported to Korea after completing his sentence last year.

A physical examination classified him as eligible for alternative service as a social service agent, but he sought assignment to wartime labor service instead. The Seoul Regional Military Manpower Administration rejected his request, prompting him to sue the agency.

The Seoul Administrative Court ruled in his favor, saying the law does not require a prison sentence to be imposed in Korea. It added that the rationale for excluding inmates from active duty — protecting military discipline and maintaining the quality of the armed forces — applies regardless of where they served their sentences.

The court also found no meaningful difference between an inmate who was transferred to Korea to finish a sentence handed down by a foreign court and one who served the full term abroad.

It cautioned, however, that recognizing prison sentences served abroad without limits could allow people to avoid military service. It therefore ruled that such a sentence counts only if the underlying offense would also constitute a crime under Korean law.

In the man's case, the court found that robbing a victim while armed and using violence and threats would constitute aggravated robbery under Korean law.
