[2009] EWHC 1071, 15 May 2009. Concerns an appeal under the Town and Country Planning Act 1990 S289 by Chas Storer Limited (C) against the decision of an inspector appointed by the SoS to dismiss C's appeal against an enforcement notice issued by Hertfordshire County Council (H) alleging a breach of planning control. The enforcement notice related to an alleged material change in the use of land used for waste processing by C, which arose from changes in the type of materials brought onto the site. The notice imposed requirements restricting the type of materials which could be processed, as well as the hours of operation and number of lorry movements to and from the site. "Held": appeal allowed. The alleged change of use did not involve hours of operation or increased vehicle movements, and these should not have been included in the enforcement notice. Referred back to SoS for re-hearing and determination.
