No charges will be brought in relation to the death of a 27-year-old man following a violent disorder incident in Temple Bar.
However, that decision by the Director of Public Prosecutions (DPP) can be appealed, an inquest into the death of Gareth O'Connor heard. The father-of-three, of Lindisfarne Grove, Clondalkin, died at St James's Hospital on September 11, 2015.
Insp Paul Costello applied to Dublin Coroner's Court for a three-month adjournment of the inquest to allow time for a right of appeal.
Gardai carried out extensive investigations into Mr O'Connor's death in the preparation of a file for the DPP.
At least seven people were arrested and questioned in relation to the case.
Mr O'Connor died after he suffered bleeding into and on to the brain, according to a post-mortem report prepared by State Pathologist Prof Marie Cassidy. He had a toxic level of cocaine in his system at the time of his death.
Mr O'Connor suffered subarachnoid and intracranial haemorrhage.
The inquest opened before former Dublin coroner Dr Brian Farrell in November 2015.
At that hearing, he reserved recording an official cause of death until a later date.
At the resumed inquest, Insp Costello said he believed three months was enough time to allow for an appeal of the DPP's decision.
Coroner Dr Myra Cullinane adjourned the inquest hearing until July 20 for further mention.
