Abousfian Abdelrazik a Canadian citizen born in Sudan was arrested when he went to Sudan to visit his mother in 2003. Sudanese authorities suspected that Adbelrazik had ties to Al Qaeda. Abdelrazik says he was tortured by his Sudanese captors and asked questions that he thinks were prompted by CSIS (Canadian Security Intelligence Service)
While he was imprisoned Abdelrazik's passport expired and he ended up having to live in the Canadian embassy in Khartoum. In July 2006 the U.S. listed Abdelrazik as an Al Qaeda supporter and the UN also added his name to a list of terrorists.
However, Abdelrazik has never been charged with anything. Quite the opposite he has been cleared by both the RCMP (Royal Canadian Mounted Police) and CSIS (Canadian Security Intelligence Agency) of any terrorist connections.
In June of 1909 Federal Court Justice Russel Zinn concluded that CSIS had been complicit in arranging Adbdelrazik's arrest. He also ruled that the Canadian government had denied his constitutional rights by not issuing him a visa to return to Canada.
CSIS asked for a prompt review of the case more than two years ago. But two years later the investigation seems to be dying a slow death. No one from the CSIS has responded to reporters' questions about the status of the investigation.
However finally Abdelarzik's name has been removed from the UN's terrorist list. Abdelrazik has been trying to clear his name ever since he returned to Canada in June 2009. If the case of Maher Arar is any precedent Abdelrazik will probably never get the U.S. to change their characterization of him as an Al Qaeda supporter. Arar is still on a no fly list. Arar was rendered to Syria after he was held during a transfer of planes in the U.S when he was on his way back to Canada. He was deported on the grounds he was an Al Qaeda supporter. He was deported to Syria even though he was a Canadian citizen and told U.S. authorities he would be tortured there. Even though there was a long expensive inquiry in Canada that cleared Arar and awarded him ten million dollars the U.S. has never changed their position. For more on Abdelrazik see this article.
