Hi all, long time lurker on this forum but never posted, not visited since my Viva nightmare last November but need some advice about publishing my failed PhD.

Long story, mature student who spent five years working on a charity funded PhD. During write up my 2nd supervisor ignored all contact and first provided positive feedback although on study leave for the last three months. Submitted on time and waited for Viva.

Viva was the worst experience of my life and it was obvious one of the examiners would not have passed me the sugar let alone a PhD! I was frankly not believed when I said how awful the viva was, exam advisor denied any problem despite reading academic papers and ignoring proceedings all the way through....
Given revise, resubmit and re-viva which I am not prepared to do as 1) the entire thesis needs rewriting according to the report and 2) I am convinced one of the examiners will never pass me and 3) lost all faith in the value of a PhD.
Advised initially by my 1st supervisor to complain about the exams advisor but basically fobbed off and unable to make big formal complaints as I work at the Uni concerned. The only way to view my examiners independant report was to make a subject access request which supported my view of events with one examiner saying pass with minor typo corrections and the 2nd saying not even worthy of a masters qualification.
So, fast forward six months and I have withdrawn from the PhD as I am not prepared to waste another year of my life on almost certain failure of a resubmitted thesis unrelated to the research undertaken.
I really don't see though, why I shouldn't publish an account of my PhD experience but obviously want to avoid being sued...... So my question is, who owns the rights to my failed thesis and can I be sued if I publish an online account of my experience and treatment at a Russel Group University?
