I keep seeing right-wingers who want to pass laws to ban "sharia law" in the United States and it's always struck me as being an attempt to find a cure for which there is no known disease. Is sharia law really applicable in any way to our courts? Or are paranoid people just attempting to strike a needless blow against something because it's foreign and Arabic? According to this article, there are a few times when sharia law, like the laws of other foreign nations, is relevant but not controlling to a U.S. court proceeding. And the answer to the second question is yes.
