I want to jump down to the bottom of the article:
"a New Jersey case, in which a judge refused to grant a restraining order against a Muslim man whose wife accused him of raping her repeatedly, made it necessary for Oklahoma to take action to keep Islamic law from being imposed there.The good news here is that the appellate court overruled the lower court. It is not clear what happened in the lower court that brought about this ruling.
The New Jersey decision, in which the family court judge found the husband was abiding by his Muslim beliefs regarding spousal duties, was overruled by an appellate court."
This particular case is:
"The amendment would require Oklahoma courts to 'rely on federal and state law when deciding cases' and 'forbids courts from considering or using' either international law or Islamic religious law, known as Sharia"This seems pretty straight forward. Use the law of the land. There is either weird judicial freedom happening, or this is over-zealousness.
