On 13-15 June, the Canadian Supreme Court heard Adil Charkaoui’s constitutional challenge against “security certificates”, under the Immigration and Refugee Protection Act. Security certificates have been criticized as violating the right to a fair trial by allowing detention and deportation without charge and trial of foreign nationals deemed to be national security threats, on the basis of secret evidence. The Court simultaneously heard challenges to conditions of detention and secret hearings, also brought by people subject to security certificates.
