 Some other theorists whose approach to group rights is consistent with what is described here as the “collective” conception are Nathan Brett (1991), Allen Buchanan (1993, 1994), Leslie Green (1991), Vinit Haksar (1998), Lesley Jacobs (1991) and Seumas Miller (2001, 2010). (See also Margalit and Raz 1990.) The collective conception need not be tied to an interest theory of rights. Miller, for example, gives an account of the collective conception that owes nothing to that theory (2001, 210–33). But the ascendancy of the interest theory of rights in recent years has meant that those who have adopted the collective conception have frequently followed Raz in combining it with the interest theory. (For criticism of the collective theory so conceived, see Griffin 2008, 261–265; Preda 2013.) Moreover, that theory does provide a ready-made account of what it is that individuals share—interests—that makes them a right-holding group. The way that interests can accumulate across individuals also helps to explain how it is that a group of individuals can have a right, as a group, that none of them possesses singly. For Raz, the number of individuals in a group can affect both whether the group has a right and how weighty its right is (1986, 187, 209). Others are less comfortable with that “aggregative” feature of Raz’s conception; yet the relevance of numbers is often hard to dismiss. Consider, for example, the claim of a linguistic minority that its language should be usable, and provided for, in the public domain. Given the public costs of meeting that claim, it would seem implausible to hold that we should take no account of the size of a linguistic minority (of which there may be several) in deciding whether the claim amounts to a right.
