Canada, 2003 SCC 45 (CanLII), [2003] 2 S.C.R. 259, at para. 60, the test for the demonstration of a reasonable apprehension of bias is as follows: What would an informed person viewing the matter realistically and practically – and having thought the matter through – conclude. Would he think that it is more likely than not that [the decision-maker], whether consciously or unconsciously, would not decide fairly.”
