  Amongst those who think that rights can be analysed, at least in part, into duties, permissions and powers, there is a further main division. Some think that the essence of a right is to have choice or control over the corresponding duty etc. Others think that the main thing is that one’s interests are protected by the duty etc. Hart and Wellman are amongst the proponents of the first view, Bentham, Austin, MacCormick and Raz are amongst those maintaining some version of the second.
