A US court has reportedly quashed the conviction of Osama bin Laden's former driver over material support to terrorism.
The US Court of Appeals for the District of Columbia Circuit ruled Salim Hamdan's offence did not constitute a war crime.
The court's judge Brett Kavanaugh said it could not support a conviction as supporting terrorism was not categorised as a war crime at the time of the actions for which Hamdan was convicted from 1996 to 2001.
"If the government wanted to charge Hamdan with aiding and abetting terrorism or some other war crime that was sufficiently rooted in the international law of war at the time of Hamdan's conduct, it should have done so," the BBC quoted the judge, as saying.
Hamdan had been the first Guantanamo detainee to be sentenced by a US military commission when he was given a 66-month jail term in August 2008.
The former driver, who is reportedly in his mid-40s, was freed in 2009 because he had already spent seven years in US custody after being captured and detained in Afghanistan in November 2001. (ANI)
