If you go on to Guy Taylor Issues – Facebook, I think – you can read the 'legal' successfully used by the redoubtable John Hurst to defeat an SPV - Hoist Portfolio Holding 2 Ltd. - in court who were attempting to claim on a debt sold to them by Barclays.
A fine collection of legal argument, criminal law, Civil Procedure Rules, Bankers Books Evidence Act, SPV's and many more attractions to delight the discerning debtor.
