  Legal rights are, clearly, rights which exist under the rules of legal systems or by virtue of decisions of suitably authoritative bodies within them. They raise a number of different philosophical issues. (1) Whether legal rights are conceptually related to other types of rights, principally moral rights; (2) What the analysis of the concept of a legal right is; (3) What kinds of entities can be legal right-holders; (4) Whether there any kinds of rights which are exclusive to, or at least have much greater importance in, legal systems, as opposed to morality; (5) What rights legal systems ought to create or recognise. Issue (5) is primarily one of moral and political philosophy, and is not different in general principle from the issue of what duties, permissions, powers, etc, legal systems ought to create or recognise. It will not, therefore, be addressed here.
