More accurately speaking, in South Korea both the congress and the president is elected by direct nationwide voting, therefore it takes a separate process for the congress to fully impeach the president: the congress votes to impeach and the constitutional court decides whether to approve it. Therefore she has not been impeached, but merely has been suspended til the decision (Roh Moo-hyun [1] is currently a sole example to survive this process). This is quite different to how the impeachment works in USA. [1] https://en.wikipedia.org/wiki/Roh_Moo-hyun https://en.wikipedia.org/wiki/Roh_Moo-hyun
