Pip medical report used previous medical

Hi I wondered if any one can help me....I have just received my medical report for me to then write a mandatory review letter. They scored me 0 points for both components. Where it states justification for their descriptor they have used the previous medical they themselves carried out 2 years previous as justification. This has been used as if the previous medical was a statement of facts despite me successfully overturning this at a tribunal and being rewarded standard care on both (again originally 0 points) My question is is it even legal for this medical assessor to do this use a previous medical? as the previous assessor was no more qualified in my conditions than she was. I also provided a lot of medical evidence myself from specialist doctors and therapists...so there was plenty of professional evidence...which was ignored. I am going to continue with my letter using the guides but wanted to know if there was a legal angle too. Thanks Nic

Thank you Gordon for such a quick response. I didn't actually put a copy of tribunal decision in with my report as i stupidly thought they would look at that themselves. But I am learning fast when it comes to the DWP include everything and don't make assumptions about common sense.
Initially i was beside myself when reading the medical report but on a positive note i have a lot of points to argue. Glad you mentioned challenging the age of information and ignoring the tribunal result as this clarifies I am going in the right direction with it...at times you really begin to doubt yourself in this process!!!
thanks again Nic
