Retired justice Terrence McMahon says university president Elizabeth Cannon didn't break any rules in her dealings over the school's Centre for Corporate Sustainability.
The investigation began after senior academics alleged that Calgary oil company Enbridge interfered with the centre after the firm provided a donation of more than $2 million.
McMahon concludes there was no academic interference — largely because there was little actual work getting done at the centre.
McMahon says there's no evidence Enbridge tried to influence who taught or spoke at the centre.
