How can anyone know what follows when we don't know what the answers are!
On a simple level. If CCFC Ltd was a non-trading subsidiary, as TF suggests, then how has it been forced into administration, as it wouldn't have any debts if it had passed on the rental costs to the trading company? Therefore, the wrong company has gone into administration. Where do we start with that? Why not ask TF what happens next?
However, as far as I'm aware, when you take control of a company, a period of due diligence ensures that the any complexities are sorted and then the new owners are responsible for the previous mistakes/errors etc of that company. It becomes their 'mess' to quote TF.
You are quite right, of course, and as he tried to explain (not well, but again, I think he was trying to choose his words carefully) the due diligence that was carried out under the original Sisu management was not as it might have been.
As for which company was placed into administration, that is surely down to ACL. They initiated the action against "Ltd", and would have put "Ltd" into administration if Sisu hadn't done so the night before.
