PhD regulations
The final word.The PhD regulations are nothing short of sacred to the PhD student. They govern all legal and organisational issues from acceptance as a PhD candidate and submission of the thesis to examinations and publication. By the way, it is important to keep an eye on which PhD regulations apply to you. Is it the version that was in force at the time you were accepted, or a later version? This can vary from university to university, so be careful, because exceptions to the PhD regulations are impossible in the vast majority of cases.
