Your examples are violations of criminal law. No contract, no matter where or when, is enforceable if criminal law is violated. Did you read the bill yourself. There is no mention of Sharia or criminal courts. It deals with foreign law and venue selection in the civil courts. You might know, but many do not that a Florida company can enter a contract with a German company that will use Turkish law adjudicated in a South Dakota courtroom. If the contract is freely entered into, then the South Dakota judge will apply Turkish law to settle any disputes. This happens all the time, and is accepted by courts in all 50 states. You probably know, but many do not, that if two Hasidic men enter into a contract based on Jewish Law, the courts will adjudicate the matter using Jewish Law if the contract so states. I just do not like government interfering in private contracts between individuals and corporations that do not violate criminal law. I have no problem with a Muslim man basing his will on Sharia law, and the courts executing the document. It is called freedom.
Sharia allows polygamy. You accept that?
