Graham Dwyer is today due to find out if his appeal against his conviction for the murder of Elaine O’Hara has been successful.

He was found guilty of murdering the childcare worker in 2015; however, he claims he was denied a fair trial.

By the time Graham Dwyer’s appeal was heard just a few weeks before Christmas last year, seven years had passed since a jury convicted him of murder.

The reason it took so long is because his lawyers decided to first challenge the law that allowed for the retention of his mobile phone metadata and the subsequent accessing of it by gardaí investigating Elaine O’Hara’s murder.

He won that challenge and unsurprisingly, the admissibility of the evidence at trial featured heavily in his appeal.

He also claimed prejudice was allowed to creep into the trial and accused the judge of making a mistake by not taking the case out of the jury’s hands due to what they claimed was a lack of evidence.

Today’s judgement will be delivered just days short of the eighth anniversary of Dwyer’s conviction.
