The role of the pro-democratic Civic Party in a court battle over the three-way Hong Kong-Macau-Zhuhai bridge was implicitly condemned by Hong Kong's chief executive, Donald Tsang, recently, when he argued that "a certain political party" was harming the city's interests. The dispute relates to the environmental impact of the project, which will span the Pearl river. The government argues that the court case could delay the HK$60bn (US$7.7bn) rail project and might entail an increase in infrastructure costs.

The Civic Party is believed to have helped a woman launch a judicial review of the legality of the environmental assessment report conducted for the project. The High Court upheld her suit on one of the seven grounds pleaded, ordering further studies on the impact of the bridge and forcing the government to launch an appeal, which could delay the start of construction work for six months. Both Civic Party legislators and Albert Ho, the chairman of the DP, have argued that Mr Tsang's comments undermine the rule of law by putting pressure on the judiciary.
