Mr. McGarrigle, the coach of the Dalhousie University basketball team, had improperly allowed an academically ineligible player to play in five basketball games in violation of the CIS rules governing the sport. When this happens, there is an obligation upon the institution to disclose the violation by submitting an appropriate letter to the governing sports body Canadian University Sports (CIS), with the result that the games involved would be forfeited. The letter was also sent to the officials of Atlantic University Sports, which had no direct role in the disciplinary process but did need to know why Dalhousie was forfeiting the specified games. Assuming some of the words in the letter were defamatory, what would be the best defense for Dalhousie in these circumstances? Explain why or why not that defence would be effective.
