Immobilisation of Vehicles: Scotland Mr. Spellar To ask the Secretary of State for the Home Department whether she has commissioned research into the effect of banning wheelclamping on private land in Scotland. Mr. Coaker The position in Scotland is determined by case law which has determined that wheel-clamping on private land amounted to theft and the demand of a release fee amounted to extortion under Scottish law. Neither the Home Office nor the Scottish Executive have commissioned research into wheel-clamping on private land in Scotland.
