The banks are doing there usual trick here (least cost to them), they have only deemed impacted the cohorts that the CBI have told them that they have to deem impacted.
They have no intention of finding any other cohorts, there are clear outlier cases that the banks themselves won't find impacted, why would they, it will be either the CBI, ombudsman or courts that force them too.
They are dragging there feet because they know that the more time that goes by, the less likely it is that people will continue to fight them.
My advice to everyone is to appeal the banks not impacted decision, either via Padraig Kissane, the courts or the ombudsman.
