*** October 2012 UPDATE ***
Permission to appeal to the Supreme Court was granted in Cook v The Mortgage Business PLC et al [aka North East Property Buyers ] - the appeal is not expected to be listed until June 2013 at earliest.
Cook v The Mortgage Business Plc  EWCA Civ 17 judgment
The proceedings concern whether sale and leaseback arrangements between tenants who had previously owned their homes and an organisation known as North East Property Buyers bind the mortgage lenders to North East Property Buyers as overriding interests under the Land Registration Act 2002. By the time of the appeal there were 4 test cases extant and around 90 cases stayed. There were also cases stayed in other parts of the country in relation to similar schemes where mortgagees are attempting to recover possession from tenants after the borrowers have defaulted.

18/10/2010 Test Cases on sale and leaseback
HHJ Behrens sitting as a Deputy High Court Judge at Leeds will commence on Tuesday 19th October 2010 hearing a trial of preliminary issues in respect of nine test cases from Newcastle County Court in respect of whether sale and leaseback arrangements between nine tenants who had previously owned their homes and an organisation known as North East Property Buyers bind the mortgage lenders to North East Property Buyers as overriding interests under the Land Registration Act 2002.
North East Property Buyers either purchased the properties at a discount or required a substantial amount to be deducted and paid to them from the proceeds of sale. The tenants say they were made promises that they could stay as long as they wanted or for life and the vast majority of them had no idea that the purchases were being funded by mortgages.
North East Property Buyers have defaulted on the mortgages and the lenders have sought possession against the tenants.
