The decision of the European Court of Human Rights that Abu Qatada cannot, for now, be deported to Jordan because of the risk of a trial using evidence obtained by torture has nothing to do with the Human Rights Act. Unless the UK were to withdraw entirely from the European Convention on Human Rights, that decision would always have been reached with or without our own Human Rights Act.
