This Order amends sections 192 and 207 of the Town and Country Planning Act 1971 (which relate to planning blight) to take account of the changes to the rating system made by the Local Government Finance Act 1988. The Order also increases from £2,250 to £18,000 the annual value limit which applies for the purposes of the blight provisions in the case of an owner-occupier of a hereditament. The blight provisions enable a person with an interest in certain categories of land (including land affected by certain planning and highway proposals) to require the appropriate authority to purchase that interest.
