At the National Assembly political strife intensified over a move to get several bills on fast-track.
The committees for judiciary and political reform were planning to meet to grant such status to bills on electoral reform and on creating an independent body to investigate corruption among high-ranking government officials.
Four parties,. without the main opposition bloc, agreed earlier this week to fast track the bills.
Speed was of the essence as parliament has to finalize the electoral map ahead of the next year's general elections.
But their plan hit a snag. on fierce resistance from the Liberty Korea Party.
Its members are blocking the venues for the meetings, emphasizing the election law needs bipartisan agreement.
The fast-track move has also sparked backlash from some lawmakers in the minor opposition Bareun Mirae Party.
Their leadership has replaced committee members who have been against the fast-track bills because those votes are critical to getting the designations approved.
