I think the key issue is that the special condition on the Letter of Approval expressly stated that on expiry of the discount period "the then prevailing PTSB tracker rate will apply".
However PTSB wrote out a month before the end of the discount period stating: your current rate option is due to expire" and proceeded to offer a range of fixed rates a variable rate and a ramped up tracker margin.
Crucially, the options letter misled customers as NO RATE OPTION WAS EVER REFERRED TO ON THE SPECIAL CONDITION GOVERNING INTEREST RATE. Rather it stated: the then prevailing PTSB tracker rate WILL apply.
Cant see how any reference to an option in the wording on the contract.
Net result: Borrowers lured off a tracker on basis of a misleading "options" letter
