The victims of violations of minority rights have been a disparate group, including individuals and small groups of human rights defenders, lawyers, religious minorities and ethnic minorities. The mandate holders also sent a considerable number of communications raising concerns about draft legislation that could have a negative or discriminatory effect on persons belonging to minorities, as well as about the lack of implementation of certain policies or action plans. 7. In terms of the reasons for the communications, the largest number of communications (94) was sent on issues concerning religious minorities. There were also 10 cases where the issues in question related to groups that qualified both as religious and as ethnic minorities. The second-largest group of victims was ethnic minorities, concerning which 72 communications were sent; 114 communications were sent on cases concerning Roma. There were 26 communications concerning human rights defenders working on promoting and protecting the rights of persons belonging to minorities who suffered reprisals, including expulsion, arrest or detention in connection with their human rights activities, and two cases concerning lawyers. In 20 cases, the victims of violations were not groups, but individuals. 23
