THE Lands Tribunal has lambasted the Government for the lack of planning regulations which allowed for the ''rape'' of the New Territories during the 1980s. It also attacked the Government's regulations to control development, brought in two years ago, as falling far short of comprehensive control. ''Important features of a mature legal system of any developed country are clear and simple laws relating to title to land . . .. So far as land-use is concerned, a comprehensive statutory planning scheme is equally desirable. Hong Kong lacks both,'' a judgment prepared by Judge Cruden and M. W. Phillips said. In the 75-page judgment, the tribunal awarded $5.2 million compensation to Niceboard Development Ltd because its 0.01 hectares in Yuen Long had been devalued by China Light and Power (CLP) placing pylons on its land. The tribunal found that had there been a proper land registration system, the dispute might not have arisen because CLP would have arranged to bypass this land. The tribunal held that both parties were ''innocent victims of government failure to provide a modern land title registration system'' and its tolerance of an unsatisfactory land use and planning scheme. ''The parties have been put to the expense of litigating fundamental issues which years ago the Government should have rendered crystal clear,'' it said. Niceboard, represented by Jason Pow, had agreed to sub-let the land to Pioneer to build a concrete batching plant. The lease was terminated because electricity pylons prevented Pioneer from constructing tall buildings. CLP, represented by Barbara Kaplan, argued the land was restricted to agriculture and so was less valuable. The tribunal therefore had to look into the use of the land, which it found was not properly documented. It eventually held on the evidence that the land use had been changed to non-agricultural and it was more probable than not that it was building land and the batching plant could have been built as a right. It therefore awarded the compensation. Up to 1981, New Territories landowners who wanted to use land for anything other than agriculture had to apply for a waiver. But this haphazard provision safeguarding land use ceased after a Court of Appeal judgment in 1981, ruling that storage fell within agricultural use. There then followed a spectacular expansion of containerisation in the New Territories, the judgment said. ''The failure to enact statutory user controls in 1981 resulted in a tragic misuse . . . of the limited land resources of the New Territories. Those who describe what has occurred as the 'rape' of the New Territories may turn out to have erred on the side of understatement rather than exaggeration.'' Two years ago, the Government tried to recover control by enacting the Town Planning (Amendment) Ordinance, but the judgment said the reform fell short of a comprehensive statutory planning scheme.
