Client Nomination

Anu has experience winning novel, precedent-setting cases on behalf of clients. He acted as counsel for the successful applicant in Canada Without Poverty v. Attorney General of Canada, 2018 ONSC 4147, a decision that struck down as unconstitutional a provision of the Income Tax Act that prohibited charities from engaging in non-partisan political speech. The Canadian Broadcasting Corporation described this case as a “landmark”, and a “David versus Goliath” win for the client. Anu was also counsel before the Supreme Court of Canada in Christine DeJong Medicine Professional Corp. v. DBDC Spadina Ltd., 2019 SCC 30, a case dealing with when a corporation can be liable for the conduct of a director. In that case, the Supreme Court expressly adopted the amendment to the law proposed by his team on behalf of their client.
