A/HRC/28/27 parent families, large families, and families from ethnic minority backgrounds being particularly affected. The Committee regretted the fact that children from ethnic-minority backgrounds had a significantly weaker record of school achievement, leaving school without having graduated from it twice as often as pupils from non-ethnic-minority backgrounds (CRC/C/DEU/CO/3-4). 40. The Committee against Torture, at its 50th session (6–31 May 2013), in regard to the Netherlands, expressed concern at the alleged incidents of illegal use of force, insults and mistreatment at the Koraal Specht prison in Curaçao and in the cells at police stations on the islands of Aruba, Bonaire and Sint Maarten, as well as at ethnic profiling by the police and border guards that had been aimed in particular at foreigners and members of minorities. It requested the State party to establish systems to obtain disaggregated data about the composition of the detainee population to avoid disproportionate representation of minorities (CAT/C/NLD/CO/5-6). At its 51st session (28 October–22 November 2013), adopting concluding observations on Portugal, the Committee was concerned at reports of discrimination and abuses against Roma and other minorities by the police. The Committee added that the State party should take effective measures to ensure the protection of members of the Roma community (CAT/C/PRT/CO/5-6). B. General comments and general recommendations 41. The Committee on the Elimination of Discrimination against Women adopted, in November 2013, its general recommendation No. 30 on women in conflict prevention, conflict and post-conflict situations, some provisions of which requested that States address the needs of women belonging to minorities. It was noted in the general recommendation that during and after conflict, specific groups of women and girls were at particular risk of violence, especially sexual violence, for example women of diverse caste, ethnic, national or religious identities, or of other minorities, who were often attacked as symbolic representatives of their community. The general recommendation also considered the specific risks and particular needs of different groups of internally displaced and refugee women who were subjected to multiple and intersecting forms of discrimination, including women with disabilities, older women, girls, widows, women who headed households, pregnant women, women living with HIV/AIDS, rural women, indigenous women, women belonging to ethnic, national, sexual or religious minorities, and women human rights defenders, as well as stateless women and girls in times of conflict (CEDAW/C/GC/30). 42. A joint general recommendation/general comment No. 31 of the Committee on the Elimination of Discrimination against Women and No. 18 of the Committee on the Rights of the Child on harmful practices was adopted in November 2014. The Committees recommended to States parties to both Conventions to take all appropriate measures to ensure that stigma and discrimination were not perpetuated against the victims of harmful practices and/or against the practising immigrant or minority communities. 43. The Committee on the Rights of Persons with Disabilities adopted its general comment No. 1 in April 2014, in which it was recalled that article 12 of the Convention on the Rights of Persons with Disabilities affirmed that all persons with disabilities had full legal capacity. It was noted in general comment No. 1 that legal capacity had been prejudicially denied to many groups throughout history, including women (particularly upon marriage) and ethnic minorities (CRPD/C/GC/1). In its general comment No. 2, also adopted in April 2014, the Committee added that States parties should take appropriate measures to enable persons with disabilities to have the opportunity to develop and utilize their creative, artistic and intellectual potential.
