PIP appeal success for a mental health condition

I acted as the appointee for my son. Having been turned down for PIP, turned down at the Mandatory Reconsideration, today we SUCCEEDED at the tribunal. We had hoped for standard living rate but received higher rate for living and standard rate for mobility. Unbelievable. We are over the moon. My local CAB was very helpful indeed and I did write a VERY in-depth supporting statement.  I am happy to pass on my suggestions.
As our appeal was around mental health we were not optimistic.
