Court overturns 9/11 conviction
Mounir el Motassadeq's conviction on more than 3,000 counts of accessory to murder and membership in a terrorist organisation was flawed as the lower court failed to properly consider the absence of evidence from a key witness who is in US custody, the Federal Criminal Court ruled.
The jailed 29-year-old's case now returns to court in Hamburg.
"The case is to be sent back to another panel of judges at the Hamburg court for a new trial and decision," Presiding Judge Klaus Tolksdorf said in reading the verdict.
But he said: "the defendant el Motassadeq is certainly far removed from being clear of suspicion."
El Motassadeq is serving a maximum 15-year prison sentence after the Hamburg court convicted him in February 2003 of giving logistical support to the Hamburg-based al-Qaida cell that included September 11 suicide hijackers Mohamed Atta, Marwan al-Shehhi and Ziad Jarrah.
After the appeal ruling, el Motassadeq's lawyers said they would ask the Hamburg court to free the engineering student from custody. Stephen Push, founder of the New York-based Families of September 11 organisation, said he was "frustrated" by the move.
