Although Christians and Jews have quietly and successfully run religion-based arbitration tribuals for a decade, they will now lose this legal right in the name of "fairness" as Ontario cannot legally exclude one religious group and allow others to continue. I guess it's a small price to pay. Too bad, though. From what I've heard, Rabbis make very good arbitrators, even in disputes involving a Jew and a Gentile.
Interestingly, in the US there is nothing preventing arbitrations from being settled using Sharia or any other religious law.
When's the last time you heard of a Rabbi ordering someone's hand cut off or an adultress stoned to death? I'm betting any rulings Judeo-Christian tribunals have dished out weren't against Canadian or American laws. So, I don't see why they should have to go away.
