The newest member of Canada's highest court says the only unifying principle that seems to stitch his life together is an abiding belief in pluralism. Justice Mahmud Jamal says that means faith in the inherent value of the diversity of nationalities, ethnicities, religions, languages, legal systems and perspectives that exemplify what it means to be Canadian. Jamal was welcomed to the Supreme Court of Canada in a ceremony Thursday, though he was officially sworn in at a private event on Canada Day.
