What is the standard of proof for a request to close a refugee hearing?

The standard of proof need not be high, however. Since the request to close the hearing can only take place in the context of a refugee claim, actual or anticipated, it would seem appropriate to apply the same test as for the claim itself. In Adjei v. Canada (Minister of Employment and Immigration) (1989), 1989 CanLII 5184 (FCA), 57 D.L.R. (4th) 153, [1989] 2 F.C. 680, 7 Imm. L.R. (2d) 169, this court identified that test as being the existence of a "reasonable chance" or "good grounds" to fear danger. As in other proceedings before him, the adjudicator may base his opinion on any sources of information which he finds to be credible and trustworthy.
