CRC/GC/2005/6 page 9 (c) Best interests of the child as a primary consideration in the search for short and long-term solutions (art. 3) 19. Article 3 (1) states that “[i]n all actions concerning children, whether undertaken by public or private social welfare institutions, courts of law, administrative authorities or legislative bodies, the best interests of the child shall be a primary consideration”. In the case of a displaced child, the principle must be respected during all stages of the displacement cycle. At any of these stages, a best interests determination must be documented in preparation of any decision fundamentally impacting on the unaccompanied or separated child’s life. 20. A determination of what is in the best interests of the child requires a clear and comprehensive assessment of the child’s identity, including her or his nationality, upbringing, ethnic, cultural and linguistic background, particular vulnerabilities and protection needs. Consequently, allowing the child access to the territory is a prerequisite to this initial assessment process. The assessment process should be carried out in a friendly and safe atmosphere by qualified professionals who are trained in age and gender-sensitive interviewing techniques. 21. Subsequent steps, such as the appointment of a competent guardian as expeditiously as possible, serves as a key procedural safeguard to ensure respect for the best interests of an unaccompanied or separated child. Therefore, such a child should only be referred to asylum or other procedures after the appointment of a guardian. In cases where separated or unaccompanied children are referred to asylum procedures or other administrative or judicial proceedings, they should also be provided with a legal representative in addition to a guardian. 22. Respect for best interests also requires that, where competent authorities have placed an unaccompanied or separated child “for the purposes of care, protection or treatment of his or her physical or mental health”, the State recognizes the right of that child to a “periodic review” of their treatment and “all other circumstances relevant to his or her placement” (article 25 of the Convention). (d) The right to life, survival and development (art. 6) 23. The obligation of the State party under article 6 includes protection from violence and exploitation, to the maximum extent possible, which would jeopardize a child’s right to life, survival and development. Separated and unaccompanied children are vulnerable to various risks that affect their life, survival and development such as trafficking for purposes of sexual or other exploitation or involvement in criminal activities which could result in harm to the child, or in extreme cases, in death. Accordingly, article 6 necessitates vigilance by States parties in this regard, particularly when organized crime may be involved. While the issue of trafficking of children is beyond the scope of this general comment, the Committee notes that there is often a link between trafficking and the situation of separated and unaccompanied children. 24. The Committee is of the view that practical measures should be taken at all levels to protect children from the risks mentioned above. Such measures could include: priority procedures for child victims of trafficking, the prompt appointment of guardians, the provision of
