Using the notion of correlativity in the Hohfeldian system of rights we not just gain a better understanding of legal relations, but we can identify and differentiate existing and non-existing rights and duties. One has to see clearly, though, who the agents are in these correlative pairs and dissociate them from the State. Using SDL with an iterable and agent-indexed STIT operator we can outline the characteristics of the relations while clearly separating these roles.
