What is law?
In any society several systems of rules operate at once: state law, customary law, religious law, professional rules and transnational norms. The state does not hold a monopoly on law.
Law and morality
Varies by order. The theory describes the coexistence and its tensions, and asks how they should be reconciled.
Where does its authority come from?
Each order has its own sources: the state, a community, a religion, a profession.
How should judges decide?
Courts may have to recognise, apply or defer to non-state norms and decide which order prevails.
The question it asks
Who decides which law applies?
Main criticism
Some positivists say that calling every normative order 'law' blurs the concept.
Legacy today
Customary and indigenous law, religious law in secular states, and the study of global governance.
