Counsel for CLAIHR prepared motions to intervene in two high-profile appeals to the Supreme Court of Canada, Charkaoui and Almrei. Both cases pertained to the constitutionality and proper interpretation of the security certificate provisions of the Immigration and Refugee Protection Act (IRPA). These provisions create a regime whereby a person may be detained and deported from Canada on national security grounds even in cases where that person faces a serious risk of torture if returned to his or her home country.
