"Social and professional contact with terrorists -- for example, such as occurs in normal interactions with friends and family members -- will not, absent the specific intent to enhance the abilities of a terrorist group, permit a conviction," the ruling said.
The court also dismissed Khawaja's claim that he was taking part in an armed conflict and should be exempt from being charged under international law. It rejected his contention that he didn't recognize the threat posed by the British terrorist organization, the Khyam group.
