What is the standard of review for an administrative tribunal to exceed its jurisdiction?

36 However, where the issue involves the decision maker's jurisdiction to decide a matter (as opposed to an issue within its jurisdiction), the applicable standard of review is not whether it is reasonable but whether it is "correct": U.E.S. Local 298 v. Bibeault, 1988 CanLII 30 (SCC), [1988] 2 S.C.R. 1048. At p. 1086, Beetz J. summarized the circumstances in which an administrative tribunal will exceed its jurisdiction because of error: 1. if the question of law at issue is within the tribunal's jurisdiction, it will only exceed its jurisdiction if it errs in a patently unreasonable manner; a tribunal which is competent to answer a question my make errors in so doing without being subject to judicial review; 2. if however the question at issue concerns a legislative provision limiting the tribunal's powers, a mere error will cause it to lose jurisdiction and subject the tribunal to judicial review.
