Jonathan Brown is a lecturer in Scots Private Law at the University of Strathclyde in Glasgow. Previously he was a lecturer in law at Aberdeen’s Robert Gordon University. Jonathan considers himself to be a private law generalist and dabbling legal historian. His recent publications include work on medical jurisprudence, the law of defamation and the relation between the Roman law of slavery and modern Scottish human trafficking legislation. The present essay is intended to provide a modern account which places acts amounting to wrongful detention effected by private persons within the taxonomy of iniuria.
