Administrative - Disclosure. Brown v. Canada (Citizenship and Immigration)
In Brown v. Canada (Citizenship and Immigration) (Fed CA, 2020) the Federal Court of Appeal holds that a disclosure duty applies under the doctrine of administrative procedural fairness when the issue is quasi-criminal (here, immigration detention):
 The interveners assert that detainees do not receive sufficient and timely disclosure to allow them to know the case they have to meet and to respond. They argue that the Immigration Division Rules fall short of what fairness requires because they, and the relevant policy guidelines, require disclosure of only the documents on which the Minister intends to rely. They also point to evidence that says that the disclosure that is made is often late and leaves counsel with no ability to adequately represent the detainee’s interests.
 The existence of a legislated disclosure requirement does not dispose of the question whether procedural fairness has been met. The Court must still examine whether the duty of fairness has been fulfilled. The Federal Court observed that Mr. Brown raised "“legitimate concerns about the timeliness and quality of pre-hearing disclosure”" (Federal Court reasons at para. 127). I agree that those concerns are substantiated by the evidence. Mr. Singh, a hearings officer with the CBSA, admits that, although disclosure is to be provided in advance, "“there are times where it is not provided in advance”" (Federal Court reasons at para. 110).
 The need for detainees to know the case against them creates a disclosure obligation. To be meaningful, the disclosure obligation cannot be limited to information on which the Minister intends to rely. All relevant information must be disclosed, including information that is only to the advantage of the detainee. This includes information pertaining to the grounds for the detention, information pertaining to the section 248 criteria, the existence of an immigration nexus, and the factors that bear upon the judge’s assessment whether continued detention is warranted and consistent with Charter and administrative law principles. While the disclosure obligation necessarily encompasses information that is helpful to the detainee, it is not unlimited. It is always tempered by the requirement that the information be relevant to the circumstances of the particular detainee.
 The lawful exercise of the power to order detention requires an adequate evidentiary foundation. This includes all relevant evidence relating to the factors under section 248. In cases of inadequate disclosure, judicial review can be sought, on an expedited basis, and interim orders can be made compelling disclosure (see section 18.2 of the Federal Courts Act). Importantly, a detention decision may be vitiated if it is established that there has not been timely disclosure of material documents which results in a breach of procedural fairness.
