United Nations Principles and Guidelines on Access to Legal Aid in Criminal Justice Systems 21 54. The privacy and personal data of a child who is or who has been involved in judicial or non‑judicial proceedings and other interventions should be protected at all stages, and such protection should be guaranteed by law. This generally implies that no information or personal data may be made available or published, particularly in the media, that could reveal or indirectly enable the disclosure of the child’s identity, including images of the child, detailed descriptions of the child or the child’s family, names or addresses of the child’s family members and audio and video records. Guideline 11. Nationwide legal aid system 55. In order to encourage the functioning of a nationwide legal aid system, States should, where it is appropriate, undertake measures: (a) To ensure and promote the provision of effective legal aid at all stages of the criminal justice process for persons detained, arrested or imprisoned, suspected or accused of, or charged with a criminal offence, and for victims of crime; (b) To provide legal aid to persons who have been unlawfully arrested or detained or who have received a final judgement of the court as a result of a miscarriage of justice, in order to enforce their right to retrial, reparation, including compensation, rehabilitation and guarantees of non‑repetition; (c) To promote coordination between justice agencies and other pro‑ fessionals such as health, social services and victim support workers in order to maximize the effectiveness of the legal aid system, without prejudice to the rights of the accused; (d) To establish partnerships with bar or legal associations to ensure the provision of legal aid at all stages of the criminal justice process; (e) To enable paralegals to provide those forms of legal aid allowed by national law or practice to persons detained, arrested, suspected of, or charged with a criminal offence, in particular in police stations or other detention centres; (f) To promote the provision of appropriate legal aid for the purpose of crime prevention. 56. States should also take measures: (a) To encourage legal and bar associations to support the provision of legal aid by offering a range of services, including those that are free (pro bono), in line with their professional calling and ethical duty;
