CAT/C/CHE/CO/7 (c) Undertake investigation of reports of surgical and other medical treatment of intersex people without effective consent and adopt legal provisions in order to provide redress to the victims of such treatment, including adequate compensation. Training 21. While noting the information provided on the training programmes for police and prison staff, the Committee finds it regrettable that it received only limited information about the training provided to other public officials in contact with persons deprived of their liberty. It also notes with concern that th e Manual on the Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (Istanbul Protocol) is not covered in this training. Lastly, the Committee is concerned that no specific methodologies exist to evaluate the effectiveness of training programmes for police and prison staff on the absolute prohibition of torture and ill-treatment (art. 10). The State party should strengthen its efforts to provide training for all officials concerned on its obligations under the Convention, as well as systematic training and practice in applying the Istanbul Protocol. It should also develop specific methodologies to evaluate the training programmes provided on the absolute prohibition of torture and ill-treatment to police and prison staff. Follow-up procedure 22. The Committee requests the State party to provide, by 14 August 2016, information on its follow-up to the Committee’s recommendations as contained in paragraph 10, on police violence, particularly subparagraph (b), on the need to send medical reports of injuries indicating ill-treatment to the independent mechanism responsible for examining them; paragraph 13, on the principle of non -refoulement; paragraph 18, on unaccompanied asylum-seeking minors; and paragraph 19, on prison conditions, particularly subparagraph (e), on the need to make inquiries into all acts of violence committed in prison facilities. Other issues 23. The Committee invites the State party to consider expediting the process of ratifying the core United Nations human rights treaties to which it is not yet a party, namely the: (a) International Convention for the Protection of All Persons from Enforced Disappearance; (b) International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families; (c) Optional Protocol to the International Covenant on Economic, Social and Cultural Rights; (d) Rights; Optional Protocol to the International Covenant on Civil and Political (e) Optional Protocol to the Convention on the Rights of the Child on a communications procedure; (f) Optional Protocol to the Convention on the Rights of Persons with Disabilities. 8/9 GE.15-15100
