Late in 2007 campaign group Friends of Thornborough requested a judicial review of the planning permission due to a number of procedural irregularities. In response, North Yorkshire County Council ruled the permission to be "fatally flawed," and withdrew the permission previously granted. It is now planned that the planning application will be re-determined by North Yorkshire County Council planning committee on 22 April 2008. Planners indicated that granting of permission was likely. However, campaign group TimeWatch raised the issue of Neolithic archaeology found within the new quarry area since the last planning meeting.
