  Austin’s reductionist account of the normativity of law, maintaining that the normative aspect of law simply consists in the subjects’ desire to avoid sanctions, was discussed extensively, and fiercely criticized, by H.L.A. Hart. Hart’s fundamental objection to Austin’s reductionist account of law’s normativity is, on his own account, “that the predictive interpretation obscures the fact that, where rules exist, deviations from them are not merely grounds for prediction that hostile reactions will follow…. but are also deemed to be a reason or justification for such reaction and for applying the sanctions” (Hart 1961, 82). This emphasis on the reason-giving function of rules is surely correct, but perhaps not enough. Supporters of the predictive account could claim that it only begs the further question of why people should regard the rules of law as reasons or justifications for actions. If it is, for example, only because the law happens to be an efficient sanction-provider, then the predictive model of the normativity of law may turn out to be correct after all. In other words, Hart’s fundamental objection to the predictive model is actually a result of his vision about the main functions of law in society, holding, contra Austin and Kelsen, that those functions are not exclusively related to the ability of the law to impose sanctions.
