It singles out Sharia Law but, is there any other religious law that could/should be included? I don't know of Jewish Law, Christian Law, Hindu Law, etc.
You clearly have not read the Old Testament.
ETA: I stand by my earlier posts on this forum that SQ755 was wrong for singling out Sharia Law, not being specific on public or private international law, and not being broad enough to cover other much more commonly used and upheld cultural defenses.
