Kong residents later about Articles 45 and 68 of the Basic Law in 2004. There were also uncertainties concerning the future of the next 2007 Chief Executive election and the next 4th LegCo elections in 2008. In response, Eu, along with other barristers including Margaret Ng and Ronny Tong, formed the Basic Law Article 45 Concern Group that advocated fully democratic processes in the form of universal suffrage in both elections.
