OKLAHOMA CITY (AP) — Oklahoma voters have approved a measure that would forbid judges from considering international law or Islamic law when deciding cases.

Republican Rex Duncan, the sponsor of the measure, called it a "pre-emptive strike" designed to close the door on activist judges "legislating from the bench or using international law or Sharia law."

Members of the Muslim community called the question an attack on Islam and some of them said they are prepared to file a lawsuit challenging the measure.
