The Advisory Committee found that some States do not recognize some minorities or indigenous people, apply restrictions on ground of ethnicity or make distinctions among them, which affects their participation in political life, or that mechanisms of consultation and dialogue with them are still inadequate. In others, the appointment of members of advisory bodies of minorities is made by State bodies, not by the minorities themselves. Other States do not recognize all rights of participation and consultation to those bodies representing some minority groups or do not facilitate the creation of associations of some small minorities. In some States constituency boundaries and the territorial structures are constantly changed, which affects stability and participation of minorities in public life. Participation of persons belonging to minorities in the police, judicial and other law-enforcement bodies was also noted as insufficient in many States parties. In most European countries the participation of Roma minorities in political life is insuficient, for many reasons, mainly lack of interest and of support of the State bodies and lack of legislation. It was noted that the participation of Roma people in political parties based on political affiliation did not produce significant results for the representation of their concerns. In States where conflicts took place, the Committee asked the Governments to overcome the post-conflict trauma and introduce positive measures to eradicate the negative consequences of practices of curtailing the number of persons belonging to some minorities in various State bodies. 3.Limits to the participation of minorities in political life may result first of all of non-recognition of minorities, of prohibitory legislation or of a climate of intolerance. It may result also from a weak organization of the minority or difficults of cooperation among its leaders; in order to be able to play a role in a society, in accordance with democratic principles, minorities have to be organised on the basis of democratic rules themselves. Most of the limits and difficulties result from the policies of the States concerned. It includes first of all the non-recognition of minorities or simply ignoring their existence. Then, legislation forbidding their organisation, directly or indirectly, may lead to the absence of any form of expressing the concerns of the group as such, of promoting such concerns, of being involved in the elaboration of programmes and projects which may affect their interests. Of particular importance are programmes and projects concerning education, the use of languages and the preservation and development of culture in the country, as well as economic projects
