“[23] …… In 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. This is a binding obligation in international law, and the spirit, if not the precise language, has also been translated into our national law.Section 11 of the Children Act 2004 places a duty upon a wide range of public bodies to carry out their functions having regard to the need to safeguard and promote the welfare of children.”
