PRO-CHINA legislator Mr Philip Wong Yu-hong faces a heavy defeat tomorrow on his move to stall draft legislation giving effect to Governor Mr Chris Patten's constitutional reform proposals. At least 27 Legislative Councillors have indicated they will vote against Mr Wong, with most legislators saying the debate was ''unnecessary'' and ''meaningless'' as the electoral bills have already been drafted and will be introduced soon to the lawmaking body. The Executive Council will this morning discuss the draft bills and it is expected they will be endorsed without any major adjustment. However, the first hint of open dissent on the proposals in the Executive Council came yesterday when Patten-appointed Executive Councillor Professor Felice Lieh-mak was quoted as saying the proposals should not be pressed at the expense of Hongkong's economy. Professor Lieh-mak could not be reached to confirm the reports carried by the Reuter news agency and a Chinese-language newspaper. ''If the economy is affected in a way that is going to be irreversible, or is going to take a few years to pick up again, then we will have to seriously consider whether there are alternatives,'' she told Reuter. ''Hongkong's economic strength and viability is our one trump card to maintain our autonomy and to really maintain the principle of Hongkong people governing Hongkong. ''Without a strong economy, our usefulness to China will be markedly reduced.'' But her Exco colleague, Professor Edward Chen Kwan-yiu, said he did not expect any difficulties in studying the legislative form of Mr Patten's political proposals. Noting that councillors were only advisers and the Governor the final decision-maker, Professor Chen said they would express their personal views without any political worries. Legislative Councillors said they could debate or amend the constitutional proposals only when the bills were put to the council. Those opposing Mr Wong's call for the Government not to introduce the draft bills are the 13 United Democrats, four Meeting Point legislators, independents Mr Hui Yin-fat, Ms Anna Wu Hung-yuk, Mr Pang Chun-hoi, Miss Emily Lau Wai-hing, Mr Vincent Cheng Hoi-chuen, Miss Christine Loh Kung-wai, Miss Roger Luk Koon-ho, Mr Samuel Wong Ping-wai and Mr Jimmy McGregor, and Mr Frederick Fung Kin-kee, of the Association for Democracy and People's Livelihood. Four other legislators, Mrs Elsie Tu, Mr Chim Pui-chung, Mr Marvin Cheung Kin-tung and Mr Timothy Ha Wing-ho, are undecided and another five were unavailable for comment. Although Mrs Tu is one of the two seconders of the motion, she said she had yet to make up her mind on how to vote. So far only pro-Beijing legislator Mr Tam Yiu-chung - another seconder - has thrown his weight behind Mr Wong. The 17-strong Co-operative Resources Centre will abstain and Dr Tang Siu-tong is likely to join them. The electoral bills to be discussed by Exco today will be based on the political blueprint unveiled by the Governor in his October 7 policy speech. The Election Committee it prescribes will be composed of ''all'' instead of ''all or most'' of the directly-elected district board members as stated in the policy speech. Meanwhile, the vice-director of the local branch of the New China News Agency, Mr Zhang Junsheng, reiterated that China would not accept any compromise plan evolved from the Governor's package. Mr Zhang said in the latest edition of Newsweek: ''I'm afraid it is difficult for us to see any prospect of reaching a compromise with Patten if he does not abandon his proposals.'' Stressing that there would not be any shadow government, Mr Zhang said: ''The aim of China is to resume its exercise of sovereignty over Hongkong but not to exert any influence over the present administration of Hongkong. ''However, I think it will be very unfortunate if the British Hongkong authorities lose their authority here because of the implementation of any wrong policies.''
