Hello -
I am having a lot of disagreements with my University, my supervisor, and my examiner. My supervisor and I did not have a good relationship towards the end of my PhD and the internal examiner he chose was a good friend of his so I believe he chose him on purpose to stall the situation for me as much as possible since he knows I need to graduate as soon as possible. I also don't agree with all of the changes proposed to the thesis (the examiners chosen were both not experts in the field but colleagues of my supervisor) however I did all of them and the examiner still refuses to approve and continues to stall. He hasn't responded to any of my emails in more than a months and it takes my supervisor weeks to do so. Long story short - can I submit the final version of the thesis without it going through the examiner? Thanks!

No, your examiner makes the recommendations to the exam board, without that, you have no PhD.

I don't see how it could possibly be in your supervisor's interest to drag things out and increase the risk of your failing to submit. If anything, s/he'll want you off her/his hands ASAP.

You would think this would be true but surprisingly it does happen.
It assumes that all supervisors are functioning human beings.

I have seen a supervisor deliberately engage in tactics such as this to screw over more than one student. If the relationship has broken down and the supervisor is a right bastard (plenty of them out there), it is no skin off their nose to keep you waiting and in fact it can amuse them to know how desperate you are for a sign off. It's a power thing.

Pissing off your supervisor (regardless of who is to blame) can be truly disastrous.
