 Raz’s conception of a collective right is tied to his interest theory of rights according to which, as we have seen, X has a right if X has an interest that suffices to ground another’s duty (1986, 166). Thus, a group of individuals has a collective right if their shared interest is sufficient to ground a duty in others, and if the interest of any single member of the group is insufficient by itself to ground that duty. When these conditions are satisfied, the group of individuals possess a right together that none of them possesses separately. In fact, Raz argues that the interests that ground a right are not necessarily limited to the interests of the right-holder; they can also include interests that others have in the right-holder’s having the right (1986, 245–63; 1994, 44–59; 1995). For example, the right of journalists not to disclose their sources is grounded not only in their own interests but also in the public’s interest in their having that right. That consideration can also apply to collective rights. The rights of a group in respect of its culture, for example, might be grounded not only in the interests of the group’s members in their culture but also in the interests of “outsiders” in the continued existence of the group’s culture.
