Likely unbeknownst to most, Rule 334.12 of
the Federal Courts Rules permits applications for
judicial review in the Federal Court to be prosecuted as class
proceedings. This is unique to judicial reviews in the Federal
Court. It offers a potentially powerful tool for persons or
businesses operating in federally-regulated industries that are
subject to decisions and regulations affecting more than one
industry participant, to challenge certain unfavourable regulations
or decisions on judicial review on a class-wide basis.
Wenham v. Canada (Attorney General), 2018 FCA 199, is a recent decision of the
Federal Court of Appeal that reminds litigants of this available
procedural avenue and provides guidance regarding the test for
certification of such a "class application" under the
Federal Courts Rules. In particular, Stratas J.A.
clarified how the "cause of action" criterion should be
assessed at certification of an "application" for
judicial review.
