"The case that proves the rule" refers to "the exception that proves the rule," an idiom meaning an unusual case (the exception) highlights or confirms the general rule by showing that a rule must exist for something to be an exception, originating from Roman law where an exception demonstrated the existence of a broader rule, like a "no swimming after 10 PM" sign proving swimming is allowed before then. While often misused today to mean an exception disproves a rule, its core meaning is that an exception validates the underlying principle or tendency.
