Every one of thousands of sects of hundreds of different faiths would jump on the bandwagon and create their very own "Laws" the courts would have to follow. If we have to endure a failed justice system it should at least be standard and the same for all citizens as equals. I think the Constitution speaks of this as far as "laws" go.
