 The prison officials argued that a prisoner must complete the administrative review process in accordance with the applicable procedural rules, including deadlines, before bringing suit in federal court.Ngo's attorneys, on the other hand, argued that this provision simply means that a prisoner may not bring suit in federal court until administrative remedies are no longer available, even if the reason they are no longer available is due to the prisoner's own non-compliance with the applicable rules.Justice Alito, for the majority, ruled in favor of the prison officials, writing that "proper exhaustion demands compliance with an agency's deadlines and other critical procedural rules because no adjudicative system can function effectively without imposing some orderly structure on the course of its proceedings."
