Local Authority X v HI and others  EWHC 1123 (Fam)
This is a case whereby information arose by way of a 15-year-old child’s disclosure to the social worker that they did not want communicated to their parents within care proceedings. The local authority considered itself subject to a duty to disclose and the guardian sought to maintain the confidentiality of the disclosure. The court weighed the issues of relevance of the information, gravity and magnitude of harm and the rights of the individuals protected by the Human Rights Act 1998 in the balance.
Birmingham City Council v AB & others  EWHC 3090 (Fam)
This is a case where the father violently killed the mother. The children were initially placed with their grandmother, who sadly misappropriated £32,500 of their compensation monies. The local authority sought and were granted care and placement orders, in a case that had many complex elements.
