What is the standard of reasonableness in a judicial review?

37 The standard of reasonableness involves asking: “… After a somewhat probing examination, can the reasons given, when taken as a whole, support the decision?” (Law Society of New Brunswick v. Ryan, 2003 SCC 20 at para. 47, [2003] 1 S.C.R. 247). As stated in Dunsmuir, the review is concerned with both the decision-making process and the outcome (at para. 47): …. In judicial review, reasonableness is concerned mostly with the existence of justification, transparency and intelligibility within the decision-making process. But it is also concerned with whether the decision falls within a range of possible, acceptable outcomes which are defensible in respect of the facts and the law.
