The applicants, federal inmates, sought a writ of habeas corpus to challenge the Correctional Service of Canada's (CSC) refusal to reclassify them to minimum security, which prevented their transfer to lower-security institutions.
The core legal question was whether such a refusal constitutes a "deprivation of liberty" reviewable by habeas corpus.
The court, applying the principle of judicial comity and reviewing extensive jurisprudence, concluded that maintaining an existing security classification does not amount to a deprivation of liberty, as it does not impose new or additional constraints on residual liberty.
Consequently, habeas corpus was not an available remedy, and the applications were dismissed.
