South Korea court frees Jehovah’s Witnesses who refused to serve in military
Two South Korean men who refused to do military service have had their convictions overturned in a landmark ruling against the government.

It is the first time an appeals court has ruled against the government in favour of the rights of conscientious objectors. A ruling is expected to follow from South Korea’s Constitutional Court on whether jailing conscientious objectors violates their constitutional rights. The UN human rights committee has called on South Korea to allow pacifists to undertake alternative community service.
A third man, Kim Hye Min, had his not-guilty verdict upheld, despite prosecutors’ calls for it to be overturned. All three are Jehovah’s Witnesses.
