Graham Dwyer has failed in his bid to overturn his conviction for murdering vulnerable child care worker Elaine O'Hara, almost eight years to the day he was found guilty by unanimous jury verdict.
President of the Court of Appeal Mr Justice George Birmingham this morning delivered the judgement of the three-judge court, dismissing all grounds of appeal including a claim by Dwyer's lawyers that the use of call data records at his trial should lead to a retrial.
Mr Justice Birmingham said: "In this case we are satisfied that the admission of limited call data evidence could not give rise to a miscarriage of justice."
