Convicted killer Graham Dwyer has won his case against the Garda Commissioner and the State over data used from his mobile phone, which was used to convict him.
Dwyer was jailed for life for the murder of Elaine O’Hara in 2015.
Ms O’Hara was reported missing in August of 2012, her body was discovered over a year later at Killakee Mountain in South Dublin.
Dwyer’s phone was found by angler’s at the Vartry Reservoir close to Roundwood, three days before her body was discovered in September 2013.
In his case Dwyer argued that phone data used in his trial should not have been used as it breached his right to privacy.
The Court today ruled that Irish laws – which allow for mobile phone data to be retained and accessed – are in breach of EU law.
It means he has won this stage of his legal battle.
Dwyer has already stated his intention to go to the Court of Appeal to challenge his murder conviction.
