I would SERIOUSLY think about this action and the reprocussions even if it IS legal, which I am not sure of. What if he dies overseas? Are you ready for that publicity? Cancelling it could really hurt you, we wouldn't even if we were able to. This is just MHO, not legal advice of course but I would talk to an attorney before taking this action.
Going to church doesn't make you a christian any more that standing in your garage makes you a car.
