If you appeal and your appeal is rejected, you can then complain to the Ombudsman.
By that time, there will be an active High Court case on the issue.
I would expect the Ombudsman to pause all cases until the High Court rules.
If the High Court finds in favour of the borrower, I would expect the Ombudsman to follow that.
If you don't appeal, you can't go to the Ombudsman as you will be time barred.
If we win the High Court case, you will have no legal mechanism for getting your tracker back.
The Central Bank might tell AIB to redress all 6,000 customers, but I would not rely on it.
That is why I want everyone to appeal.
