Terror suspect in release bid
A lawyer for Mounir el Motassadeq, 29, submitted the formal request to the Hamburg state court.
A federal court last week threw out the Moroccan's conviction on more than 3,000 counts of accessory to murder and membership in a terrorist organisation the world's only conviction for the 2001 attacks on the United States. El Motassadeq is serving a maximum 15-year prison sentence.
