  More recent versions, such as those of Raz (1984a, 1984b), take a different tack altogether. According to them, to say that X is a right-holder is to say that his interests, or an aspect of them, are sufficient reason for imposing duties on others either not to interfere with X in the performance of some action, or to secure him in something. This, inter alia, gets round the third-party rights’ problem, because the explanation is simply that it is all a question of whether the system recognises the interests of Z as part of the reason for X and Y’s duties, or whether it is only the interests of X and Y. Raz (1997) has emphasised that this does not mean that only the right-holder’s interests are relevant to the question of whether something should be recognised as a right. Considerations of the general or common interest may be relevant too.
