An Oxford graduate's failure to get a top degree cost him a lucrative legal career, the High Court has heard.
Faiz Siddiqui alleges "inadequate" teaching on his modern history course resulted in him getting a low upper second degree in June 2000.
He blames staff being absent on sabbatical leave and is suing the university for £1m.
Oxford denies negligence and causation and says the case is "massively" outside the legal time limit.
Mr Siddiqui also alleges medical information about him was not submitted to examiners by a tutor.
The 39-year-old studied at Brasenose College and singled out the teaching on the Indian special subject part of his course for criticism.
