South Korean illegal surveillance incident
The South Korean illegal surveillance incident (Korean: 민간인 불법사찰 사건, or illegal civilian surveillance incident) was alleged to have occurred in 2010 when the Civil Service Ethics Division (공직윤리지원관실) under the Prime Minister's Office of South Korea inspected a civilian, a political action that is illegal under the South Korean conventions. The incident re-emerged in early 2012 as the election approached.
