THE Commissioner for Police Mr Li Kwan-ha is facing mounting pressure to put his No 1 licence plate up for auction with the Director of Audit Mr Brian Jenney joining the call for him to give up the plate for the good of the public. But Mr Li remained unmoved, insisting there was no pressing financial need to auction his number plate, according to a police spokesman. Mr Jenney recommended in his value-for-money report that the ''1'' and ''2'' number plates ''which were hitherto allocated to government vehicles for the sole use of two senior government officials'' should be retrieved and put up for sale by auction. Financial Secretary Mr Hamish Macleod was a step ahead of Mr Jenney's call by offering his No 2 plate for sale in February. The plate fetched a record $9.5 million, which would go to the Lotteries Fund for charity. Mr Jenney said the number of lucky vehicle registration marks to be auctioned should also be increased. By the end of last year, there were 40,000 unallocated special registration marks plus a certain number of reserved marks pending sale by auction while the number of outstanding requests from the public stood at about 750. Special registration marks are recognisable by their basic symmetry or coincidental relationship such as 111 or 3456, and the reserved marks are mainly those bearing the No 8. Mr Jenney said the administrative arrangements for auctioning the lucky number plates should be improved to settle the outstanding requests. In 1991-92, slightly more than half of public requests for the lucky number plates were satisfied, with 458 registration marks put on sale against the 727 requests made by the public. Waiting time also increased from eight to nine months in November 1989 to 17 months in September 1992. The long waiting period for the requested marks is attributable to the shortage of auctioneers and clerical staff to cope with the increasing backlog. Last September, the Commissioner for Transport undertook to double the number of auctions from once to twice a month. Despite this, the number of outstanding requests increased from 728 to 750 during this period, with an estimated nine months' waiting time. Mr Jenney recommended a performance target be set on the waiting time. To shorten the waiting period and to generate more revenue for the Lotteries Fund, the transport chief proposed to sell the less attractive marks at a fixed fee instead of by auction. The proposal, endorsed by the Secretary for Transport in February 1990, has yet to be put in place. Mr Jenney has also called for a comprehensive review of the administrative practice in the transfer of special registration marks and the transferability of the reserved marks.
