Lloyd Patrick Rayney (b. Aden, Yemen 1962)[1] is a former Western Australian barrister and Crown prosecutor who came to prominence when he was charged and acquitted in 2012 of the murder or manslaughter of his wife Corryn Rayney. In 2017, he succeeded in a defamation action against the State of Western Australia over police behaviour and was awarded a record sum of $A2.62 million. In a long-running action, the WA Legal Professional Complaints Committee and the State Administrative Tribunal had his practising certificate cancelled for "professional misconduct" and "knowingly giving false evidence".
