I agree about the article being very interesting. It's a rather interesting notion of divorce being not-applicable to religious marriages putting a lot of monostream canadians in the crosshairs of s.293. I would have liked to see the author being around for representations during the court case.
Speaking of which, the running commentary on the court case in BC is here:
BC Reference Case on Polygamy and Group Marriages
We're still waiting on a verdict...and regardless of which way the finding goes, it's just the start.
