I READ with interest Candy Wong's recent column regarding the Housing Authority, ''Now is the chance to put own house in order''. I agree with her assertion that it is time to make the Housing Authority more open and accountable to the public and consumers. People are no longer willing to accept the old paternalistic system of quiet understandings and limited accountability, as it has often benefitted a narrow group of insiders at the expense of consumers' interests. The Housing Authority's policy on the supply of energy to domestic premises is a case in point. Towngas benefits tremendously under the authority's policy of mandating the use of Towngas in public housing estates located in areas where Towngas is available. This gives Towngas an effective monopoly over the supply of domestic energy to the huge public housing sector, even though it is not subject to any Scheme of Control. The Housing Authority has maintained this policy favouring Towngas despite the fact that central supply LPG is cheaper and has been successfully and safely used in many private housing complexes for more than a decade. The Housing Authority's energy policy is not based on legislation, but rather on an internal administrative directive. As such, it has never been the subject of public debate or scrutiny. Limiting competition through administrative fiat is unacceptable in a free and open society. EDWARD H. OLD, managing director, RALPH W. PERRY, general manager & director, Caltex Oil Hongkong Ltd.
