From the 1st Observer article:
"Months later, James’s business went bust and in 2010 his loan to the Walkers was transferred to two men he owed money to. The men called in the Walkers’ loan and, when they didn’t pay , took them to court in 2012. During the case James filed a witness statement in which he told the court that “the purpose of the loan is clear: it was required to settle a criminal allegation made against Mrs Walker”.
The court ruled that the Walkers had to repay the debt – which with interest now exceeded £150,000. If they failed to do so within one year, the new creditors could repossess their home.
The Walkers, who were both out of work, had little hope of finding the money. But they came up with an extraordinary plan. Less than two months after the judg ment, Sally and Tim started their own company, Gangani Publishing. It only ever published one novel, How Not to Dal dy Dir (Stand Firm), written by an unknown writer called Izzy Wyn -Thomas.
Readers were encouraged to purchase the novel directly from Gangani’s website, which is no longer active. And the Walkers offered an intriguing enticement. For every copy bought, purchasers would be entered into a free prize draw with a chance to win the Walkers’ home in Wales – the same property that a judge had ordered to be repossessed if they didn’t sell it.
In the prize draw’s terms and conditions, the Walkers said the house was being “offered free of mortgage or any other legal or registered charge”. In fact, at this point the couple had a mortgage of £230,000 in addition to the loan to James. The house was worth less than these sums combined.
It isn’t known what happened to the money raised from this enterprise or whether the Walkers returned the proceeds after their house was finally repossessed in June 2013."
So the final court case was in 2012 and the repossession in 2013.
