Awaiting an Ombudsman decision but now bank wants to return to mediation!!!

I have a case with the Ombudsman for 4 years.
It went through the normal processes - complaint to the bank and Ombudsman mediation before the exhausting exchange of correspondence.
The bank has been absolutely firm in their dismissal of any of my arguments.
It's been well over a year since it went to adjudication and I am waiting for the decision any day now.

And now out of the blue, the bank has asked the Ombudsman to refer it back to mediation.

Has anyone heard of this before? Is it worth going back to mediation?

Hello,

If you don't want to return to mediation, just say so. You can say the you've no confidence in it resolving matters to your satisfaction, having tried it previously.

My guess is that the institution in question has been given a signal (or just sense) that there's going to be a ruling against them.
