Agreed. I guess the question then is whether an exception to a rule is put there to "screw" some number of pilots or as a deliberate and/or logical circumstance under which the rule would not apply.

As an example, it was explained to me in C2K that the circumstance outside the control of the Company exception was a deliberate part of the overall negotiation in which we went from unlimited reroutes with no premium pay so long as you did not touch your base, to the system we have now where you can go through your base but you get reroute pay if the Company chooses to keep you out longer than originally scheduled.

Not intended to screw anyone, but rather to provide a financial disincentive for the Company to keep you out longer than necessary. If your airport is closed, then there is no physical way to get you back, and no amount of reroute pay will change that.
