Host Marie-Claude Desrosiers speaks with Chief Justice J.C. Marc Richard and Justice Kathleen A. Quigg, of the Court of Appeal of New Brunswick, about the implications of the Supreme Court of Canada’s decision in Vavilov for the judicial review and appeals of decisions of self-regulatory professional bodies and other expert tribunals. They explore the meaning of reasonableness and correctness review, how deference may still play a role, and how decisions of self-regulatory professional bodies may now be reviewed.
