I think that a graphic would have helped viewers to follow the story but here are the facts as I understand them. I have attached the full High Court decision in the case.
Borrowed in excess of €1m from ptsb on his family home and his wife's family home(?) in Dublin to buy "numerous" investment properties.
All loans were on interest-only tracker mortgages with an average margin of 1.3%.
7 December 2006 Fixed loans in excess of €1m for three years.
At the end of the fixed rate period, he would default to the tracker rate "appropriate to the balance outstanding on the loan at the date of expiry of the fixed rate period.)
Interest rates fell so fixed loans were more expensive than rates in the market
Early January 2009 - he heard Shane Ross on Matt Cooper telling ptsb customers that they could break out of their fixed rate and face no penalty.
This is a really big issue. Why did ptsb not have the usual penalties for people breaking out of fixed rates? They say it was a programming error but it is suggested that it was intentional as those who broke out of fixed rates early would lose their right to a tracker.
13 January 2009 - rang ptsb and claims to have been told that he would go onto a variable rate temporarily and then revert to the tracker rate in December when the fixed rate was scheduled to end.
He broke out of his fixed rate and went onto the variable rate.
In December refused a tracker.
complained to Ombudsman
17 August 2010 - Ombudsman issued a decision rejecting his complaint on the grounds that the Ryans were warned about the implications of switching to a variable rate “through the documentation furnished to them at mortgage inception”.
6 Sept 2010 - Started appeal to the High Court.
As part of the preparation for the case, he then did a Data Request and they sent him a transcript of the phone call which he claimed backed up his claims.
The Judge issued his decision on 23 Sept 2011.
It's important to realise that the Judge does not hear the case from the start. He just decided that there was new information which might affect the Ombudsman's decision had it been known at the time, and sent it back to the Ombudsman to hear again.
July 2015 - ptsb launches review of all tracker cases and so all ptsb cases before the Ombudsman are put on hold.
In about 2017 or 2018, he and many others were put back on trackers by ptsb.
Many had a price promise, so they went back on ECB + 1%.
But the Ryans had a price promise on only one of their mortgages, and so they got a refund based on ECB +3.35% - the rate prevailing when their fixed rate was due to end.
