SOME of the legislators' criticisms of housing and environmental issues were due to misconceptions, the Secretary for Planning, Environment and Lands, Tony Eason, said. He rejected accusations that limits, set out in the Joint Declaration, had constrained the supply of land and led to high property prices. The Land Commission had granted more than the 50 hectares of land supply allowed every year under the Land Disposal Programme, Mr Eason said. The commission had released 58.4 hectares in 1985, 164.3 hectares last year, and 127.8 hectares this year. The land intended for public housing, private residential and commercial/ residential development was 12.6 hectares, 44.8 hectares and 46 hectares in 1985, 1992 and 1993 respectively. ''Once again convenient myths about the administration maintaining so-called high land prices and private sector-led housing policies have been trotted out without much regard to the plain facts,'' Mr Eason said. ''Some members seem to suggest that if we increase the supply of land for private residential development, property prices would be brought down.'' Mr Eason also challenged the claim that the first phase of the sandwich class housing loan scheme was below expectations. ''Why he [the legislator] should find a 31/2 times over-subscription disappointing is hard to fathom,'' he said. ''We think it was a very good start. We do not expect or want everyone in the sandwich class to become dependent on the scheme.'' Commenting on the legislators' views, Mr Eason said: ''Inevitably, the speeches reflected some misconceptions and some persistent mythology, which only increased our resolve to inform and better educate members.''
