"Mr. Diab was committed for extradition on June 6th, 2011 by the Superior Court of Justice," Justice Department spokesman Christian Girouard wrote in an email. "On April 4th, 2012, the minister of Justice ordered his surrender to France.
"Mr. Diab has 30 days in which to seek judicial review of the minister's decision. In addition, he has appealed his committal to the (Court of Appeal) for Ontario. As this matter remains pending in the Canadian courts, it would not be appropriate to comment further."
Diab's lawyer told the Ottawa Citizen he will appeal the extradition through to the Supreme Court of Canada if necessary.
Last year, Ontario Superior Court Justice Robert Maranger ruled Diab must be sent to France under the terms of Canadian extradition law.
Maranger's ruling left it up to Nicholson to decide whether to surrender Diab to France. The justice minister was supposed to make his decision on April 18.
Since Diab has challenged Maranger's decision in the Ontario Court of Appeal, he is likely to remain in Canada for several more months and quite possibly longer.
French authorities say Diab, a Canadian of Lebanese descent, was involved in the 1980 bombing of a Paris synagogue that killed four people and injured dozens of others.
The RCMP arrested Diab in November 2008 in response to a request by France. He had worked as a contract instructor at two Ottawa universities.
Diab denies any role in the deadly attack.
