The Tenth Justice tells the complete story of one of the strangest sagas in Canadian legal history: the ill-fated appointment to the Supreme Court of Canada of Justice Marc Nadon.

The process by which Supreme Court judges are appointed is traditionally a quiet affair, but this certainly wasn’t the case when Prime Minister Stephen Harper selected Justice Marc Nadon for appointment to Canada’s highest court. Here, for the first time, is the complete story of “the Nadon Reference” – one of the strangest sagas in Canadian legal history.

Following the Prime Minister's announcement, controversy swirled and debate raged: as a federal court judge, was Marc Nadon eligible for one of the three seats traditionally reserved for Quebec? Then, in March 2014, the Supreme Court of Canada broke new ground in statutory interpretation and constitutional law when it released the Reference re Supreme Court Act, ss 5 and 6.

With detailed historical and legal analysis, including never-before-published interviews, The Tenth Justice explains how the Nadon Reference came to be a case at all, the issues at stake, and its legacy.
