Updated at 5.24pm: An unemployed Hong Kong man has filed a judicial review to challenge the legality of the territory's Chief Executive election, local media reported on Friday. The plaintiff, Chan Yuet-tung, lodged the lawsuit in the High Court on Friday afternoon. Mr Chan said that the upcoming election might breach the Basic Law - the territory's mini-constitution, local radio reported. Mr Chan earlier claimed he would be a candidate for Chief Executive. He handed in a blank nomination form to the Electoral Affairs Commission last week. He said the present Election Committee - which will select the territory's leader in the July 10 election - consisted of only 796 members, four short of the 800 required by the Basic Law, local radio reported. Further details on Mr Chan were not available on Friday afternoon. But Mr Chan has said he would personally promote the lawsuit. He said he would not need a lawyer to help him as he had completed a master's degree course in law while in prison in Belgium, Apple Daily reported on Thursday. He said his move was not to sabotage the election or 'stir things up', but to help him win the top post.
