Bandon man Graham Dwyer has won his European case regarding the retention of phone data.
The collection of data by the gardaí was a crucial element of evidence in his conviction in 2012.
Dwyer was charged in October 2013 with the murder of Elaine O’Hara and was convicted by a jury at the Central Criminal Court in March 2015.
He was jailed for life.
He will now continue his legal challenge against his conviction.
