Hong Kong needs to address an "unreasonable" imbalance in the nominating committee for the 2017 chief executive election, a Beijing legal scholar told the Sunday Morning Post . Professor Chen Duanhong of Peking University's law school also said there was room for talks on giving more people a stake in choosing the nominating committee. Chen was speaking ahead of a decision expected today from the National People's Congress Standing Committee on a framework for Hong Kong's 2017 chief executive election, when the city picks its leader by "one person, one vote" for the first time. The committee is expected to endorse a model under which only two orthree candidates may run for the office after they have secured the support of at least half of a 1,200-member nominating committee. Sources said the NPC was likely to require the nominating committee to be modelled on the 1,193-person Election Committee that nominated and elected Leung Chun-ying two years ago. That body consists of four sectors - business, professional, social and political - each encompassing several subsectors. The Election Committee has been criticised as unfair, not least because a small subsector such as agriculture and fisheries elects 60 representatives, while teachers and lawyers choose just 30 representatives each. All the 70 members of the Legislative Council sit on the Election Committee. And just 250,000 voters from the subsectors choose the rest of the committee members. Hong Kong's electorate numbers 3.5 million. On the subsectors' composition, Chen said: "As Hong Kong is such a highly educated society ... ruled by law, it is really quite unreasonable to have so few representatives from the legal and education subsectors." Chen's comment was in contrast to an answer he gave in June at a public forum in Hong Kong. During the forum, Civic Party leader Alan Leong Kah-kit asked whether the academic believed the imbalance between subsectors suggested that the city's farmers and fishermen were more important than its lawyers and teachers. Chen replied that he had not studied the Election Committee in detail. He said the committee's composition "can certainly change. And how to change it is to be discussed … and it would depend on the importance that society places on these" subsectors. A source warned on Friday that if the wording of the Standing Committee's decision required that the nominating committee's composition follow current provisions, the size of the subsectors could not change. Chen countered that it would be impossible for the decision to go into that much detail. Apart from the nominating committee's composition, Chen said Hong Kong should also discuss how to improve voters' participation. While he stopped short of calling for the nominating committee to be elected by all voters, he said more members of the subsectors - such as employees of businesses represented - should have a say.
