The fact that they rarely or may not actually pursue the matter is a different topic.

The passenger has engaged in a contract to use both legs of the ticket - not just one. As another poster also pointed out, BA can refuse to carry you until they reprice the existing ticket.
Lets make this simple and ask the BA Lurker.....
I think we will have to agree to disagree on this. If you look carefully at section 3 of the Conditions of Carriage, you will see that they do not require a passenger to take a return leg, but to take the coupons in order. I can see no term of the contract that requires the passenger to take the return leg, or provides for what should happen in such a situation. If I have missed it, please let me know. And in any event, there is nothing in these terms or elsewhere that permits BA to make unauthorised debits from your credit card.
