This report is a localnews.ie summary based on public court reporting and records; sources are listed below.

Garrett O'Brien’s appeal against his murder conviction was dismissed by the Court of Appeal on 27 June 2017. He had also been convicted of possessing a firearm with intent to endanger life at the Central Criminal Court on 6 November 2012.

The appeal challenged the lawfulness of his arrest, the handling of telephone evidence and the absence of a specific jury finding on whether he was the gunman or participated in a joint enterprise. The court rejected those arguments and held that the verdict could not be undermined by the jury not giving a more detailed explanation.

O'Brien had received a life sentence for murder and a ten-year sentence for the firearm conviction. The judgment recorded that the murder occurred in Tallaght, Dublin, on 13 March 2009.
