ACFC/56DOC(2016)001 minority communities are adequately taken into account. National minority communities, as is the case in any community, are diverse and their members often hold divergent views. This means that the diversity within the minorities, including women and young people, as well as their various needs and concerns, must be effectively represented in all relevant decision making. 78. Controversies may arise between factions among or within minorities and it is the responsibility of the state authorities to seek flexible solutions that can accommodate them, ensuring that they are all enabled to participate effectively. It is therefore essential for governments to have standards and procedures available to put in place suitable arrangements for the promotion of the effective participation of persons belonging to minorities, in consultation with those concerned. In addition, these arrangements must be sufficiently flexible to allow for renegotiations when conditions or priorities change. In a number of states parties, the granting of different forms of self-governance or autonomy (territorial and non-territorial) is used at regional level, to varying degrees, in order to protect further and more thoroughly and to promote the rights of persons belonging to national minorities. These instruments are fully in line with the international law principle of territorial integrity and can be a useful tool to promote the enjoyment of minority rights, particularly with respect to the preservation and development of minority identities and cultures.109 109.
