In contrast with other divisions of the League of Nations, the Minorities Section tended to limit its missions. The Section did not support treaty extensions nor did it consult non-governmental entities ; it did not alert the public about the rise of fascism. In addition, the Section contributed to identifying non-state national demands to “communitarian claims”. In fact, it did not consider conflicts between majorities and minorities as political conflicts between concurrent collective and individual rights. Little studied until now, decisions on non-receivability of petitions, notably those not covered by the treaties, illustrate these hypotheses. Independently of the influence of great powers, the Section supported a political philosophy in favour of majorities’ nationalism, compatible with the juridicisation of the field.
