What is the legal test for an abandoned appeal?

The Law Society’s position is that the settlement of the appeal resulted in it being abandoned, and an abandoned appeal is the equivalent of the often quoted statement that a decision is final once “all avenues of appeal have been exhausted”: see, for example Wilson v. The Queen, 1983 CanLII 35 (SCC), [1983] 2 SCR 594 at 599. The Law Society points to the form filed with the court to bring a close to the appeal. The mandatory language of that form provides that the appeal has been abandoned.
