After House Speaker Chai Chidchob called a quorum, Pheu Thai MP Somkid Bantaisong voiced doubt over whether Democrat MPs were properly registered.
He alleged that government MPs might use others' ID cards to register. Somkid then asked to walk around in order to inspect the Democrat MPs.
As soon as Somkid walked over, Democrat MPs called Somkid to inspect his registration and there was a quarrel between them.
Suddenly, Democrat MP Pramual Aimpia tried to punch and kick Somkid, but missed him as many MPs came in to stop any fight.
After all MPs got back to their seats, Pramual shouted "You, come, I'm not afraid of you!"
The shouting prompted Chai to call for peace again.
The quorum showed 317 MPs attended the session. However, the vote result showed only 307 MPs attended the session.
Later, Pheu Thai MPs Somkid and Sunai Junllapong-sathorn held a press conference to condemn Democrat MPs for the clash. Sunai claimed the problem would not have happened if Chai had not let some MPs use others' ID to register.
Later at a Democrat Party press conference, Democrat MP Kampon Supapang said that Somkid began the fight. Another Democrat MP Soravuth Neangjumnong said he smelled alcohol on Somkid.
