Hundreds of confidential Federal Court documents revealed the evidence that prompted the Canadian Security Intelligence Service to label the men as foreign terrorists, CanWest News Service reported Saturday.

Mohamed Mahjoub, Mahmoud Jaballah, Mohamed Harkat, Adil Charkaoui and Hassan Almrei are the men at risk of deportation under a new Canadian law allowing the government to deport foreign terrorists, the report said.

The court documents also reportedly made public several intelligence methods used to pin the suspects, including phone wiretaps and clandestine searches.

The Federal Court will decide if each of the cases is reasonable, but some critics said the process will be a "secret trial" because so much of it will happen out of the view of the public, the report said.
