THE Heung Yee Kuk has thrown down the gauntlet to Legislative Councillors by issuing a seven-point attack on plans to end male-only inheritance in the New Territories. In a statement to be published as an advertisement in newspapers, the rural body says it will not abide by legislation which it decides is contrary to the Basic Law or Joint Declaration. The statement compares the rights of New Territories residents with those of native Americans, and other indigenous ethnic groups. The kuk, the sole statutory advisory body representing 700,000 indigenous inhabitants in 27 rural committees, also draws attention to the fact that male primacy exists in the British Royal family. The statement accuses the Government of supporting without consultation the amendment to the New Territories Land (Exemption) Bill, made by Legislative Councillor Christine Loh Kung-wai, which would end the tradition of male-only inheritance. ''The customary land inheritance system followed by New Territories indigenous villagers is in practice the execution of an unwritten will observed through the generations,'' the advertisement says. ''It truly reflects and realises the wishes and the proprietary rights of the rural landowners. The Government cannot use the pretence of sexual equality to wrongfully suppress it.'' The document goes on to cite the special provisions granted Maoris, American Indians, Polynesians in Hawaii, and the Chamorros in Guam as a practice the Hong Kong Government ought to copy with respect to its own indigenous people. ''Customs are normal practices observed down the generations. They are vital elements to the settlement of disputes and the maintenance of social stability. Respecting and protecting the minorities' social structure, religion, their cultural traditions and their customs are the internationally accepted code of legislative standard. These customs should not be discarded off-handedly on the slogan of sexual equality.'' But legislator Ms Loh said: ''I don't think 700,000 New Territories indigenous people want to be compared with native Americans. And Chinese societies - China and Taiwan - have already abolished customary practice preventing women inheriting land.'' On the subject of the British monarchy, the document says: ''The treatment given to the male and female offspring [in terms of succession rights] are obviously distinct . . . their further existence merits preservation.'' The document concludes by accusing Governor Chris Patten of failing to match his promises to build up trust with China and solve the problems of housing and the living environment. ''The latest proposal is nothing but another of his deliberate attempts to incite a hitherto non-existent hostility between the urban and rural population . . . We will battle to the very end to protect our village, our clan, our way of life. ''From today onwards, we will not accept or abide by any legislation or policy that is contrary to the Sino-British Joint Declaration or the Basic Law of the Hong kong Special Administrative Region. This is our only choice!'' Ho Tung-ching, executive member of the new body, Headquarters for the Battle to Defend Our Home, said: ''We expressed our dissatisfaction through different channels but the Government turned a deaf ear to our views. We had no choice so we plan to issue this statement and declare our firm stance. ''We are not against all the Hong Kong laws. The only legislation and policy we will not accept and obey is to challenge our traditional custom and break our inheritance rights.'' Mr Ho said the body would use ''legitimate and suitable'' methods to handle the matter if the bill was to be passed. ''If they [the Government] use law to seize our rights, we will protect ourselves by law.'' Daniel Lam Wai-keung, convenor of the new body's action group, said: ''We will seek legal advice in order to ensure that our indigenous inhabitants can enjoy male-only inheritance in the New Territories but we will not violate the legislation.''
