Ahenakew v. MacKay

In the Ontario Court of Appeal decision of Ahenakew v. MacKay, official recorded here, all registered political parties were held to have a legal existence separate from their individual members and are entitled to regulate and control their own internal affairs. This includes any measures contrary to their own political party constitution that can be approved by a 50%+1 vote.

Arthur Hamilton and Laurie Livingstone successfully argued this precedent-setting case before the Ontario Court of Appeal on June 1, 2004. These two, with Robert Kligman, later argued successfully against The Honourable Sinclair Stevens v. The Conservative Party of Canada, their client, to prevent Stevens from re-forming a Progressive Conservative Party of Canada under its original name.

All lawyers who have argued this have worked for Cassels Brock.
