Last class we looked at the negative side of Harts project. He tried to rehabilitate legal positivism
by discarding what he though was dispensable (command theory) and explaining what he thought was
positive. The command theory of law in Austins view gave a positive explanation of how law could be
law. Hart wants to reject this rule. We now need some other account of what makes law law like.
In Harts opinion, law as the union of primary and secondary rules. Why does a legal system need
secondary rules? But does his version really counter the gunman situation?
A. What makes a rule into a rule of law? How can we fill this gap that (taking the command theory
out) we are left with?
Begins with a thought experiment in order to show why a legal system needs secondary
rules. He asks us to imagine a society with the following features: they only have primary rules (dont
murder other people, dont injure other peoples property, these are rules telling others how they should
behave, lay down a series of dos and donts). There is no legislature, courts, officials, or other authority.
Nor are there rules about how these rules should be enforced or applied. No authority vested in
interpretations or applications of these rules. Could such a society even exist? What kinds of problems
would a society like this have?
1) There would be no way of deliberately changing the rules in a way that everyone in the society
would have to recognize and accept this change. The static character of rules. Its not that it could never
evolve in terms of beliefs or moral practices but that there would be no deliberate way of doing this (at a
particular point in time) or ensuring that everyone would recognize the change (and take it into account).
The change would happen slowly and hazardously.
2) Problem of inefficiency. When disputes arise about what rules say there would be no authority
to resolve these sorts of disputes (or exert pressure for conformity to said rules). There will always be
disputes of these sorts, but there would be no authority to resolve them.3) The problem of uncertainty. Related to number two but comes prior to it. When doubts arise
as to what a particular rule is in a particular case. What things count under certain rules and what does
These problems suggest that we need secondary rules. They are on different level from the primary
rules but they are about the primary rules. They specify how primary rules can be changed, implemented,
ascertained, and who is to do this (and how they are to do this and enforce it). How they come in and out
of existence and how they should be interpreted.
To solve these three issues there are three remedies:
(1)The rule of recognition: one of the most important. Group of rules, or set of rules that lays
down particular features (of a group of rules) of primary rules in order for them to be laws. It tells us
what has to be true of primary rules in order for them to be valid laws. May require that laws have to be
properly enacted, laid down by a judge in a fair trial or that they conform to the constitution (including a
charter of rights or the like), etc. In Canada our rule of recognition includes: the law has to conform the
Canadian Charter of Rights and Freedoms. It divides powers between provincial and federal governments.
How does this fix the problem of uncertainty? It sets some standards against which we may measure
what a law is and is not. It tells us the sorts of procedures that have to be followed if something is to count
as a law or not. * The rule of recognition is key because this is what we look at to see what a valid law is
in the legal system. *
