Harts conception of law.

At first impression Harts conception of law, as a symbiotic relationship between primary and secondary rules, and more importantly the internal aspect seems valid. However in his attempts to define "What is Law" he has wandered into the social elements of law and how it relates to the group living under a legal order. Hart's interpretation of law falls into the pitfalls it was meant to avoid, mainly that law is a set of rules, claiming the union of primary and secondary rules distinguishes it from primitive societies who are governed under the rule of custom and tradition.

Defining the internal aspect is important before continuing the discussion for it is an integral part of Hart's conception of law. Harts concept of the internal aspect distinguishes between social rules and social habits. The latter is merely convergent behaviour of people within a social group, for instance, people waking up in the morning and reading the newspaper while eating breakfast, or people going to the cinema on a Saturday night. A crucial distinguishing feature from a social habit and a social rule is that habits lack criticism from others in a group when the convergent behaviour is deviated from. Deviation from the convergent behaviour makes criticism and the rule legitimate, and often is manifested through normative language such as "you ought to", or "you should do", a certain type of behaviour. There is no normative consideration when one speaks of going to the cinema on Saturday or reading the newspaper while eating breakfast, this is what distinguishes a rule from a habit. It must also be noted, that for Hart, the general rule can go on unnoticed by the group. It is only until a minority deviates from the standard behaviour that the group recognizes it as a rule to be obeyed and conformed to. Thus making all criticism towards the deviants justified and legitimate because it is the criticism that makes the rules binding and individuals have an obligation to follow the recognized standard of general behaviour.

The internal aspect and therefore rules, is an important constituent for Harts conception of law, because essentially law is the union of primary and secondary rules. A primary rule imposes duties and prescribes how one must act by way of recognizing a general standard mode of behaviour. The secondary rules consist of three important characteristics, which can be characterized as sub rules, which give the concept of rules as law and obligations, but more importantly, laws as a system of rules. The three sub rules within secondary rules act as power-conferring rules, to individuals or legal organs. First is the rule of recognition, which helps to determine whether a rule is indeed a rule, this is determined by the influx of criticism for deviation of the rule and the existence of social pressures to conform. The second, denoted as the rule of change, which allows for the creation of new primary rules or the change and modifications of old rules for the group to live by, these rules are also subject to procedural standards. The final characteristic is the rule of adjudication that determines whether or not a primary rule has been violated and prescribes the procedure the courts must follow to apply sanctions. There is also a strong connection with the rule of adjudication and the rule of recognition "because, if the courts are empowered to make authoritative determinations of the fact that a rule has been broken, these cannot avoid being taken as authoritative determinations of what the rules are."1

Indeed, the mosaic of the internal aspect, a primary and secondary rule as law is very attractive, for Hart is able to explain, where Austin has failed, power-conferring laws without a coercive order where a threatened "evil" is present. Primary rules are laws, because they are general and span over the territory in which the sovereign has authority, and secondary rules are a means to enforce and amend the laws. The power conferred to the individual is not a duty, but merely powered conferred to identify rules and the breach of obligations, this is justified by inextricably linking ...
