OTTAWA - An accused terrorist who won a landmark ruling at the Supreme Court of Canada three weeks ago will get a chance to carry another case to the top court.

In a ruling released without comment, the court has agreed to hear new arguments from Moroccan-born Adil Charkaoui as part of his continuing campaign to stave off deportation.

Charkaoui was one of three men who scored a historic victory in late February, when the high court struck down the federal system of security certificates used to kick terrorist suspects out of the country.

But the judgment won't be fully implemented for a year, to give the Conservative government time to rewrite the law.

That leaves Charkaoui in legal limbo, but he has continued to fight on other fronts to quash the proceedings against him once and for all.

He filed a claim in the lower courts arguing he was denied fundamental justice because the Canadian Security Intelligence Service destroyed notes and tapes of its interviews with him.
