It's in a variety of stages. Essentially it's being challenged at the trial level. For example, in Ontario we now have dozens of different trial decisions speaking to whether or not that legislation should be applied retrospectively or on a forward basis. It's a patchwork quilt.
No superior court or court of appeal that I'm aware of has ruled on that issue yet. And in terms of its constitutionality, again, I'm not aware that there's been any authoritative decision on that either. So it's going to work its way up slowly, and it's taking time.
