You have to realise just how antiquated and unjust the English legal system is concerning debt, bankruptcy and insolvency.
In most countries, if you go bankrupt, you have that debt until you repay it. Bankruptcy does not absolve you of any debt or obligation. In the UK, you can go bankrupt every three to five years to clear your debt and start your next venture again by going into debt without a worry in the world.
This is an appallingly bad law that is taken advantage of time and time again and must be revised to stop the abuse. For instance, it is quite clear that SISU deliberately set things up to use this useless law to get rid of their obligation under the rental contract with SISU. They did this deliberately and quite openly, using the law to abuse the system. Everybody knows they did this, nobody is denying they did this, and yet a lot of people support them doing this because it means they can sit in their seat at 3pm on a Saturday afternoon.
This sort of thing happens multiple times daily in both the private and business sectors, and will continue until the law changes and people have to then be responsible for their debt. Given the state of morality in the UK, I think a change in the law may be a long time coming, and a change in the morality of those responsible for football in this world will be a long way behind even that!
