The Supreme Court has approved the transfer of Jose Padilla from military custody to the custody of the warden of a federal detention center in Florida, to face criminal charges contained in an indictment filed November 17, 2005. The government has held Padilla as an enemy combatant since 2003.
Padilla was originally accused, but never charged, with plotting to set off a "dirty bomb," or crude radioactive device, in the United States. Padilla was indicted in November on charges of conspiring to murder U.S. citizens and to provide material support to terrorists. His trial is scheduled to begin in September.

UPDATE: The interesting question is whether this transfer now moots his pending challenge to the administration's enemy combatant policies. Eric Muller of Is That Legal? offers this post arguing that the case is mooted.
