WASHINGTON AP – Two Americans who are being held by the military in Iraq want U.S. courts to keep them from being transferred to Iraqi custody, another Supreme Court case that tests executive authority in wartime.

The Bush administration is telling the justices that U.S. courts are powerless to intervene in the cases of Mohammad Munaf and Shawqi Omar because they are being held by international forces, not the U.S. military. The court is hearing arguments in the cases Tuesday.
