Roh and his supporters left the Millennium Democratic Party in 2003 to form a new party, the Uri Party (). Directly ahead of the National Assembly elections, Roh voiced support for the Uri Party, which constituted a technical violation of Constitutional provisions mandating presidential impartiality. After Roh refused to apologize, led by the opposition parties holding the majority, the Assembly voted to impeach him for illegal electioneering on 12 March 2004. The vote was 193–2 (Uri Party members abstained from the vote). Roh's supporters physically blocked the motion for three days in open combat, and had to be hauled out by security guards. Roh's executive power was suspended pending a final decision by the Constitutional Court, and Prime Minister Goh Kun ran the country as the Acting President.
