[holding answer 10 September 2008]: I refer my hon. Friend to the answer of 26 November 2007, Official Report, column 23W, on Roads: Construction. The guidance notes that were placed in the Libraries of the House in November 2007 were incomplete, but they were all that could be found on file within the Highways Agency and the Treasury Solicitor's Department at that time. The cost of searching for the missing guidance notes now would be disproportionate.
