A candidate who was still battling to pay his $50,000 election deposit as the deadline for nominations passed on Wednesday was eliminated from the poll yesterday. The nomination of non-affiliated hopeful Ha Siu-Kwong in Kowloon West was invalidated after the returning officer sought legal advice. Mr Ha - who declared his occupation as 'an inventor and a Chinese herbalist who has given free medicine and treatment for 32 years' - turned up less than an hour before nominations closed at 5pm with $46,000. But he was still unable to pay the outstanding sum by the deadline, despite desperate efforts by friends to raise the money. A spokesman for the Registration and Electoral Affairs Office said the Legislative Council Ordinance stipulated that a nomination made without the required deposit would be invalidated. Mr Ha also failed to complete the 'promissory oath', a declaration that he is not a civil servant and does not have a criminal record. Mr Ha was a district board member in the 1980s. He earned the nickname 'The Frog Prince' after once suggesting the introduction of an African species of rat-eating frog to help get rid of rodents in Hong Kong. There are now three tickets fighting for the four seats available in Kowloon West: the Confederation of Trade Unions, the Democrats, the Democratic Alliance for the Betterment of Hong Kong and the Association for Democracy and People's Livelihood.
