“If they wanted to use Islamic law to settle the dispute, they should have never taken to a US court, they should have taken it to one of their religious leaders.”
Exactly, Judge Nielson should have told them to go away as this is a CIVIL court, not an Islamist court.
To be fair, the judge has clarified his position and says that if it comes to trial, he will be using common law to settle the matter, not sharia law. But the question he is being asked should never have been, they want to know if sharia law was followed properly in the divvying of funds. Not exactly his area of expertise but he will attempt to answer the question anyway.
