RTFA. Ph.D "student". There is no 'graduation' as such. The university can refuse to accept the submission.

Yes there is a graduation as such for Ph.D. students -- it's not such a big deal seeing as it happens post viva/defence and many students don't turn up in person however it is still required to get the piece of paper that says Doctor of Philosophy on it.
Submission tends to be covered by laws as well.
