CRC/C/GC/10 page 14 prejudging the outcome of the trial. States parties should provide information about child development to ensure that this presumption of innocence is respected in practice. Due to the lack of understanding of the process, immaturity, fear or other reasons, the child may behave in a suspicious manner, but the authorities must not assume that the child is guilty without proof of guilt beyond any reasonable doubt. The right to be heard (art. 12) 43. Article 12 (2) of CRC requires that a child be provided with the opportunity to be heard in any judicial or administrative proceedings affecting the child, either directly or through a representative or an appropriate body in a manner consistent with the procedural rules of national law. 44. It is obvious that for a child alleged as, accused of, or recognized as having infringed the penal law, the right to be heard is fundamental for a fair trial. It is equally obvious that the child has the right to be heard directly and not only through a representative or an appropriate body if it is in her/his best interests. This right must be fully observed at all stages of the process, starting with pretrial stage when the child has the right to remain silent, as well as the right to be heard by the police, the prosecutor and the investigating judge. But it also applies to the stages of adjudication and of implementation of the imposed measures. In other words, the child must be given the opportunity to express his/her views freely, and those views should be given due weight in accordance with the age and maturity of the child (art. 12 (1)), throughout the juvenile justice process. This means that the child, in order to effectively participate in the proceedings, must be informed not only of the charges (see paragraphs 47-48 below), but also of the juvenile justice process as such and of the possible measures. 45. The child should be given the opportunity to express his/her views concerning the (alternative) measures that may be imposed, and the specific wishes or preferences he/she may have in this regard should be given due weight. Alleging that the child is criminally responsible implies that he/she should be competent and able to effectively participate in the decisions regarding the most appropriate response to allegations of his/her infringement of the penal law (see paragraph 46 below). It goes without saying that the judges involved are responsible for taking the decisions. But to treat the child as a passive object does not recognize his/her rights nor does it contribute to an effective response to his/her behaviour. This also applies to the implementation of the measure(s) imposed. Research shows that an active engagement of the child in this implementation will, in most cases, contribute to a positive result. The right to effective participation in the proceedings (art 40 (2) (b) (iv)) 46. A fair trial requires that the child alleged as or accused of having infringed the penal law be able to effectively participate in the trial, and therefore needs to comprehend the charges, and possible consequences and penalties, in order to direct the legal representative, to challenge witnesses, to provide an account of events, and to make appropriate decisions about evidence, testimony and the measure(s) to be imposed. Article 14 of the Beijing Rules provides that the proceedings should be conducted in an atmosphere of understanding to allow the child to participate and to express himself/herself freely. Taking into account the child’s age and maturity may also require modified courtroom procedures and practices.
