it has been said many times previously on this topic alone, that the captain of any a/c that he is in command of, has the final say on any particular persons carriage - period! he is the commander. he carries the rank and is paid his salary because of the resonsibility that he carries, as "the buck stops with him". that said, he must also accept full responsibility for his actions. if this means that he refuses carriage to any passenger (for whatever reson) he must justify his actions, at the time and later at any inquiry. IF, and i repeat IF he is later proven to have made an error of judgement (as hard as it may to beleive sometimes - captains are human afterall) he must be prepared to accept the consequences. as none of us here, were present at the time of this passengers refusal, and only heard infomation 2nd or 3rd hand - we can't comment on the exact circumstances.
