A family which launched a legal bid for the right to sue police for neligence over the death of young mother Joanna Michael has been turned down by the Supreme Court.
Ms Michael, aged 25, of St Mellons, Cardiff, was stabbed to death by her ex-boyfriend Cyron Williams in a "mad fit of jealous rage" in 2009, despite dialling 999 twice.
The court heard that "individual and systemic failures" by police meant the emergency services arrived too late to save her life. She told the operators that he had threatened to kill her, but the message was not passed on correctly and the call was downgraded.
The family had hoped to overturn a ruling given in 2012 which stated that police have an "immunity" from negligence lawsuits under common law for actions by officers during "the investigation or suppression of crime".
However, the Supreme Court judges upheld an earlier ruling that the family could proceed with a claim that their human rights were breached by a police failure to protect Ms Michael's life, despite a cross-appeal by the chief constables of South Wales and Gwent Police.
Williams, 19, was sentenced to life with a minimum of 20 years for the killing, which saw him stab his former partner 72 times.
