Wasn't it more about satisfying entry requirements? Qatar Airways had flown Ghosheh to Amman, even though Amman had said that they wouldn't allow him into the country, until he had renounced his links with Hamas. It was Jordan who had deported him previously. Is it not the airline that is responsible for returning passengers refised entry, to the port of embarkation? However, Captain Bedeiwi would not let him board the aircraft, because he did not have a valid re-entry visa for Qatar. Oh, and Ghosheh was also a Jordanian national, to confuse things even more! I think he eventuallly went to Bangkok, and was allowed back into Jordan about two weeks later, after he issued the required renouncement.
Have never seen any mention of a court case, successful or otherwise, but then I can't read Arabic!
