Hire a lawyer. They can get you a real answer. What you get on Flyertalk may be useful for travel things, but specific legal questions will only be answered in a qualified way by an attorney. Should you disagree with the rule and be impacted by it, you can always go to the court system. I'm thinking that it won't go anywhere and an attorney will tell you that it will be a monumental waste of your time. At least you'll have your actual answer.
