Passage or principleAustin's Command Theory - Core Elements
John Austin's analytical jurisprudence, developed in his lectures published as 'The Province of Jurisprudence Determined', sought to define law with scientific precision by separating the question of what law is from what law ought to be. Austin defined positive law as the command of a sovereign, backed by a sanction, issued to a political inferior who is in a habit of obedience to that sovereign. The sovereign, for Austin, is a determinate person or body of persons who receives habitual obedience from the bulk of a given society and who does not habitually obey any other determinate human superior. Sovereignty, in this conception, is illimitable and indivisible: no legal limitation can bind a true sovereign, and sovereignty cannot meaningfully be shared between coordinate bodies. HLA Hart, in 'The Concept of Law', mounted an influential critique of Austin's command theory. Hart argued that the command-sanction model, while plausible for criminal prohibitions, fails to account for an important category of legal rules: power-conferring rules that enable private individuals to create, modify, or extinguish legal relations, such as rules governing the making of contracts, wills, and marriages. These rules are not orders backed by threats; rather, they are facilities or powers granted to citizens, and their non-compliance results not in a sanction but in nullity (the transaction simply fails to have its intended legal effect). Hart also pointed out that Austin's theory struggles to explain the continuity of legal authority across a change in the identity of the sovereign, and the persistence of laws after the lawmaker's death or departure from office, since a 'command' is generally understood as time-bound to the will of the one issuing it. Hart proposed instead that a developed legal system is best understood as a union of primary rules (which impose duties or confer powers, governing conduct directly) and secondary rules (rules about rules, including the rule of recognition, rules of change, and rules of adjudication). The rule of recognition, in particular, provides the ultimate criteria by which the validity of all other rules in the system is to be assessed, and exists as a matter of social practice among officials, rather than as a hypothetical presupposition (as in Kelsen's Grundnorm) or a sovereign command (as in Austin's theory).
