Before I make any points (below), kindly recognise I am not a legal expert or have any formal training in any other than UK housing law!
I have wondered and mentioned before though, when a developer goes to administration (insolvency), the banks are placed in the position of preferred creditors. If there is law (and developed case-law) under 57/1968, does this not allow (at least part of) the consumers money in the banking system to be treated in the same way in future? There must be some consideration of this in the way the money is 'trapped' in the system?
In Ciaron's case, to be recognised as a creditor, is the money Ciaron is claiming also included in the banks own claim of the developer I wonder (in other words is any of this money listed twice!). Once by the bank as the account of the developer and again by the deposit of the individual?
For the money to be recognised by the insolvency, I am assuming there is sufficient proof given to that procedure for the money to be paid in a recognised and accountable way? Surely Ciarons lawyer can look into this to find that proof, and to be honest I would expect Ciaron to have the receipts for this being paid too.
Again I expect this to have been discussed and proven at pre-trial stages and not left until the final trial, with things taking so long it is immensely important to ensure all documents and angles are covered at that stage, it can cost years and years afterwards. I think the lawyer has some direct culpability in these matters if the paperwork is missing (without discussion with the client as a chance case).
