In a very reputed private university, there is a rule for sending thesis to internal(national) and external(international) examiner for evaluation. After a report from two reviewers, a viva is conducted. For the last few years, I am noticing that some departments are inviting local professors to thesis defense who have virtually no research relationships with the thesis. They are being invited just because of financial constraints or quid pro quo relationship between professors who just do this to please their friendly peers in academia. By inviting local professors, the university is saving up money from travel and lodging expenses.
Is this process legal?
