Thus, if Hart’s theory is true, in order to defend a preferred theory of legal interpretation, a theorist must argue either: 1) that the way in which the theory takes a provision to contribute to the content of the law is incorporated in the rule of recognition because it is treated as correct by a large majority of judges; or 2) that the way in which the theory takes a provision to contribute to the content of the law is validated by a criterion that, in turn, is treated as correct by a large majority of judges.[37] This would be a challenging task. (As these are the only two possibilities that Hart’s account allows, to the extent that there is no consensus on a theory of legal interpretation and no criterion grounded in consensus that validates a particular theory of interpretation, it is indeterminate which theory of interpretation is correct.)[38]
