Copenhagen 1990 (28) The participating States recognize the important expertise of the Council of Europe in the field of human rights and fundamental freedoms and agree to consider further ways and means to enable the Council of Europe to make a contribution to the human dimension of the CSCE. They agree that the nature of this contribution could be examined further in a future CSCE forum. (…) IV (30) The participating States recognize that the questions relating to national minorities can only be satisfactorily resolved in a democratic political framework based on the rule of law, with a functioning independent judiciary. This framework guarantees full respect for human rights and fundamental freedoms, equal rights and status for all citizens, the free expression of all their legitimate interests and aspirations, political pluralism, social tolerance and the implementation of legal rules that place effective restraints on the abuse of governmental power. They also recognize the important role of non-governmental organizations, including political parties, trade unions, human rights organizations and religious groups, in the promotion of tolerance, cultural diversity and the resolution of questions relating to national minorities. They further reaffirm that respect for the rights of persons belonging to national minorities as part of universally recognized human rights is an essential factor for peace, justice, stability and democracy in the participating States. (31) Persons belonging to national minorities have the right to exercise fully and effectively their human rights and fundamental freedoms without any discrimination and in full equality before the law. The participating States will adopt, where necessary, special measures for the purpose of ensuring to persons belonging to national minorities full equality with the other citizens in the exercise and enjoyment of human rights and fundamental freedoms. (32) To belong to a national minority is a matter of a person’s individual choice and no disadvantage may arise from the exercise of such choice. Persons belonging to national minorities have the right freely to express, preserve and develop their ethnic, cultural, linguistic or religious identity and to maintain and develop their culture in all its aspects, free of any attempts at assimilation against their will. In particular, they have the right (32.1) - to use freely their mother tongue in private as well as in public; (32.2) - to establish and maintain their own educational, cultural and religious institutions, organizations or associations, which can seek voluntary financial and other contributions as well as public assistance, in conformity with national legislation; OSCE Human Dimension Commitments 79
