Career

He was offered the position of master of Caius, but declined it in favour of joining the International Court of Justice.

His interest was in the common law and he lectured on contract at Cambridge, though he was most notable as an international law expert. R. Y. Jennings said McNair was of the opinion that international lawyers must first become experts in private law in order to ensure legal actions are founded in "hard law" rather than speculation.
