There is an alternate interpretation, that the existence of an explicit exception proves (confirms) the existence of a rule to which an exception can be made.
So the (existence of an) exception proves (the existence of) the rule.
That's what I always thought it meant. For example, if a sign says "No Parking 4-6 PM" that proves that parking is allowed there at all other times.
