What is the test for intervening in a finding of fact made by an administrative tribunal?

Section 18.1(1)(d) essentially codifies the way the courts have viewed findings of fact made by administrative tribunals. In Kibale v. Transport Canada (1988), 90 N.R. 1 (F.C.A.) at 4, leave to S.C.C. refused (1989), 101 N.R. 238 (S.C.C.), Pratte J.A. stated that "even if the court is convinced that a decision is based on an erroneous finding of fact, it cannot intervene unless it is also of the opinion that the lower court, in making its finding, acted in a perverse or capricious manner, or without regard for the evidence." Not only must the finding of fact be perverse or capricious or without regard to the evidence before the adjudicator, this court must make such a finding if it is to interfere pursuant to s. 18.1(4)(d).
