In addition, the information provided by the source indicates that the individuals were held incommunicado at the initial stages of their detention, and none of them appear to have been able to challenge their detention in accordance with article 9 (4) of the Covenant. As the Working Group has argued, holding persons with no access to the outside world, in particular to their family members and lawyers, violates their right to challenge the lawfulness of detention before a court under article 9 (4) of the Covenant20 and article 37 (d) of the Convention on the Rights of the Child. Judicial oversight of the deprivation of liberty is a fundamental safeguard of personal liberty and is critical in ensuring that detention has a legal basis.21 Given that the five individuals were held incommunicado and were therefore unable to challenge their detention, their right to an effective remedy under article 8 of the Universal Declaration of Human Rights and article 2 (3) of the Covenant was violated.
