The Supreme Court agreed on Friday to rule on claims by two U.S. citizens being held by the U.S. military in Iraq that they have a right to challenge their detention there and future transfer to Iraqi authorities — one of them to be tried, the other to be executed for a prior Iraqi conviction. The cases, drawing the Court more deeply into defining the rights of detainees, will be heard together, probably in March. The cases are Munaf v. Geren (06-1666) and Geren v. Omar (07-394). The D.C. Circuit reached different results on the two; both, however, involve interpretation of the scope of the Court’s 1948 decision in Hirota v. MacArthur. That decision barred U.S. courts from ruling on overseas detention of Japanese nationals by U.S. military forces serving as part of a multi-national force.
