Thanks for the reply Michael - if only it were that simple. I shall continue badgering for updates
We were told the following:
RBS has set-off sums due in its PPI redress, but it has not re-proven its claim within the proceedings. It is not clear from the documentation whether or not RBS still have a claim, given the set-off value is lower than the SoA value. The letter from RBS implies there is no claim, but I would think for that to be the case, they will have to have taken the dividends paid into account. Indeed when you consider the dividends paid on some of these accounts, RBS will in fact owe the estate money in refund.
If the bank does not reprove, its claim will be thrown out, the result of which will be the request from the IP for all of the dividends back, plus interest.
I can only advise that this is an incredibly unusual situation affecting any insolvency proceedings with RBS claims that will unlikely happen again for some time.
