THE CANADIAN PRESS/Adrian Wyld] OTTAWA - A lawyer for Mohamed Harkat says the security certificate process being used to deport the Algerian refugee is unconstitutional. Harkat, a former Ottawa pizza delivery man, faces removal from Canada under a certificate that declares him a security threat due to alleged terrorist links. He denies any involvement with political extremism. Lawyer Norm Boxall is telling the Federal Court of Appeal the security certificate system is fundamentally unfair because Harkat doesn't know details of the allegations against him. The Supreme Court of Canada struck down the system five years ago, saying it violated the Charter of Rights and Freedoms. But the government revamped the process and reissued certificates against Harkat and others in early 2008. A judge ruled in late 2010 that the retooled certificate system was constitutional. Harkat is challenging that ruling this week. © 2012 Winnipeg Free Press. All Rights Reserved.
