Legco has sought compensation from pro-democracy lawmakers Ted Hui, Ray Chan and Chu Hoi-dick for hurling smelly objects and liquids during a number of meetings over the past two months.
The chairman of the Legco commission, Andrew Leung, said Ted Hui needs to fork out HK$52,000, while Ray Chan and Chu Hoi-dick needs to each pay the council around HK$100,000 in cleaning, carpet changing and odour removal fees.
The three had thrown smelly objects and liquids inside the council chamber and a conference room in a bid to disrupt Legco's scrutiny of the contentious National Anthem bill, which was eventually passed on June 4.
"It damaged not only the carpet, and also some of the clothing of security personnel. Therefore as usual we will claim back the money," Leung said.
Speaking outside Legco after Leung's announcement, Chu said he had no regrets over his actions.
"It is our obligation as legislators to exercise direct action in order to stop a legislation that violates the basic human rights of Hong Kong people," he said.
"So we have no regret for our actions two weeks before, and it is clear that the action going to be taken by the Legislative Council Commission is to threaten legislators for their future actions within the chamber or the council itself," he said.
"But I insist that if we are faced with another unjust legislation or our finance committee agenda which violates the rights of Hong Kong people, we as legislators will have no hesitation to take action to fight against it."
