Evan Ramstad reports on "Fistfight Theater in Korea Parliament":
South Korea’s parliament has no filibuster or any other method for opposition parties to slow down legislation they don’t like. Most of the time, the opposition party lawmakers simply vote their votes and let the ruling party take responsibility for good or bad legislation.
But when lawmakers want to show that they really don’t like what the ruling party is doing, they resort to trying to physically control the chamber where the vote takes place. And their staffers are enlisted into a day or two of shoving, pushing, furniture stacking and unstacking, barricading doors, occupying podiums, yelling, singing, hair-pulling and so on.
Generally, it is mayhem that stays within limits. For instance, in July 2009 when opposition lawmakers engaged in fisticuffs to express displeasure with media-reform bills, they made a deal with ruling lawmakers to shove each other with their chests and shoulders and not lift their arms and hands to each other, according to staffers.
