How (if at all) can the right to liberty of a child under Article 5 European Convention on Human Rights ('ECHR') be balanced against the rights of parents, enshrined both at common law and under Article 8 ECHR? Is there a limit to the extent to which parents can themselves, or via others, seek to impose restrictions upon their disabled child's liberty so as to secure their child's interests? This case considers the answers to these questions given by and the implications of the decision of the Supreme Court in September 2019 in Re D (A Child) [2019] UKSC 42.
